Pattern Shift Now Occurring, Rain chances Increase

Complex mid-upper level pattern developing today over the NE states
and South Central into the Northern Gulf. The trough further south will not effect Florida directly later today, but will do so Monday and Tuesday before possibly lifting out almost due north to NNE by mid-week

TODAY: As expected , noted 48 hours ago (per the GFS weather forecast model), full pattern swing is in place today. Onshore easterly winds will be less prevalent today, remaining close to the coast as upper level westerlies and mid level SW winds, albeit light increase by mid afternoon. High clouds over parts of the state seem to be getting ready to clear to some degree. The GFS has been consistent with showing the greatest instability from south of I-4 to Miami, mainly due to some drier mid-level air further north.  The Short Term Analysis at the Storm Prediction Center access point (aka, Mesoscale Analysis Page) shows this well via high down draft CAPE values, working toward the Beach Line (Dead Central zones). 

If so, it might be hard for thunder to come by today in that area except toward I-95 and east from near Titusville and southward. It is possible some thunder could be experienced therefore in North and Central Brevard County today after 4-5pm, although the depiction below shows only rain showers as storms might have a hard time shooting high into the atmosphere against the down draft CAPE in the presence of warming upper level temperatures. 

The better chance for thunder is shown in orange.  As noted above, the upper level temperatures are expected to warm later today as warmer air aloft is drawn northward ahead of a strengthening low pressure area to our west also previously shown.

Again, Northern More zone at this time lacks drivers and instability, but the GFS is showing some rain along the east coast later today all the way up to JAX (which is not shown in the post today). It also shows possible thunder in Brevard (also not shown). There is no sign of thunder producers being imminent as of noon time with few cumulus clouds (the harbingers of thunderstorms) showing up on satellite imagery and days are getting shorter. But, changes are in progress as we read and write in the grand, synoptic scale. For purposes of today's post, have taken thunder out...except as shown in orange.

MONDAY-TUESDAY: Much better chances of rain and thunder many areas as moisture increases from the South, being pulled northward ahead of a low pressure trough deepening and shifting east ward.

WEDNESDAY: This too could be another transitional day if the trough to our west begins to lift northward. If so, mechanisms for the east coast thunder machine could begin to wane, yet, moisture remains under the auspices  foreboding the chances of coastal and offshore showers and inland daytime thunder; but, thunder could occur almost anywhere really, with limited nocturnal activity toward the beaches. 

There is no "down for the count at any particular time" rain-outs lurking around the next bend, but rain chances  do remain to be accompanied by  warm over night lows and continued status quo day time highs in the limelight through the remainder of this coming week into next weekend.

Summersolstically Inclined Trend Foreseen

Splish Splashing Outlook Continues Be By  Land or  By Sea

TODAY: Not much different today than yesterday. Upper level temperatures this morning are surprisingly  very cool at 700 - 500mb aloft, but warmer 500mb air is expect (around 20,000 ft aloft) later today as high pressure at that level expands east ward across the Gulf as it gets spread out by an approaching and developing low pressure level boundary in the form of a cool to stationary frontal boundary over the weekend which is shown later in the post.

Otherwise, with respectable mixing ratios and deep layer convergence now occurring over the South Half of the state, suspect that is there that the bulk of the showers and thunder will occur, first along a slowly developing sea breeze as showers closer toward the coast with possibly thunder near the eastern side of   Big Lake Okeewhatever  with outflows and later day storms manifesting as instabiliyt builds with the full onset of the east coast sea breeze inland.  Any strong storms it appears as of this hour will be from near Yeehaw Junction and South into the Glades and western portions of the Broward/Dade Miami Metro areas.

Most activity very isolated except maybe late today. Activity over South Florida could move off toward the SW Coastal regions as indicated but overall shower and storm motion will be extremely slow to indiscernible

WEEKEND: Frontal boundary taking shape from off the coast of Maine South and westward into SE Texas by tomorrow. This boundary will serve as the main focus of rains all along that region especially near Coastal Texas to Southern Alabama and maybe Pensacola, with the brunt of rainfall occurring right near the region of Louisiana impacted heavily by the Hurricane a while back.Rainfall totals could climb toward 8" or more locally if the GFS (Global Forecast System) weather forecasting model verifies . 

Locally, not a big change tomorrow from today for Florida, with only a hint of the boundary getting closer to the Florida Peninsula prior to sunset Sunday.  In that regard, inland thunder but isolated again possible Saturday and more so on Sunday with some coastal showers possible before and at the time immediately preceding onset of the east coast sea breeze (like today). 

Continued warm and even more muggy on Sunday as this summer like pattern becomes more reminiscent of the Dog Days of mid-August rather than post Autumnal Equinox.

Watching that low to form near Central Texas which is forecast to shift east into next week toward Louisiana, never really reaching Florida as it stands now. SW Steering aloft is expected over the state Monday - Wednesday, showers and thunder much more likely during that time frame most areas, esp. Tuesday.

INTO NEXT WEEK: Increasing showers and thunder chances through Wednesday after which time the GFS becomes (as would be expected) less consistent in regard to the evolution of the synoptic scale pattern over the Eastern United States, especially over Florida. 

The only agreed upon resolution within that model's robotic mindset is that cooler weather is no where to be seen into Mid-October if not later than that unless a big shift from the trend occurs. This is a bit unusual, as by now we would have experienced a cool morning in the upper 60Fs at the beaches if not statewide which has yet to materialize. None is yet to be found or foreseen though.

"Beware of False Prophets"  

Big Pattern Change Is Being Projected By the Weekend

Pool Side Blooms Leave Honeysuckle Aroma Many Yards Away

This Morning Near Sunrise

Early Model Imagery shows the potential for a mid level trough to form northeastward from the Gulf toward Early Next Week, after the trough currently (as shown) over the northern states presses on east 

TODAY: Small, light showers near and north of I-4 inland a way could linger off and on as high cloud jet stream cirrus clouds (mainly) continue which began yesterday across much of the peninsula. The jet streak (wind speed max well aloft), might lift out late today before sunset, and if so, we could see significant clearing many areas about or before that time later today. Otherwise, mostly cloudy due to high clouds and some mid clouds  with possibly some showers as noted below.

Meanwhile, little change to the current pattern, although suspect the high clouds could be on the wane by tomorrow as steering aloft is expected to become more westerly; no longer from the moist, source region near the SW Gulf.  The GFS has been showing for several days off and on an inverted like trough to form once the trough over the Great Lakes presses off the east coast over the weekend, allowing the mid-level trough to re-emerge and form a broad, moist swath off 'troughiness" across Central Florida (somewhere) by late weekend into much of next week, much like an 'elevated warm front'. 

The net result would be increasing rain chances especially toward the weekend or so into much of the first week of October. The details are too vague at this point to get into finer details, but for now it appears we could be in for more cloudy/showery, and possibly some thunderstorm like conditions contingent upon where (and if) that boundary materializes. Little change in temperatures are being projected out through 10 days, although as days grow shorter mornings could be a bit cooler and with cloud cover so too the afternoons.

Similar To Yesterday, Slow Moving Showers and Thunder

SUNRISE Cape Canaveral with rain storm back drop, TODAY, Saturday

See Captions above

TODAY: Another short blog post today. Biggest concern for east coasters in Brevard is for an Air Show scheduled. Clouds will be in the picture all day putting a damper on high flying "Bird" viewing, but outside of that winds quite light, crickets chirping, and a moist atmosphere will provide for drifting rain showers and thunderstorms as noted in orange. Note that those orange thunder areas are a first best guess, but are there as shown as well to indicate 'sparse thunder' rather than to signify exactly where it will occur.

SUNDAY: Rain chances might shift further south yet as a mid level impulse passes to our north. This is the theme for the next 10 days..mid level impulses and/or very shallow surface fronts making only benign daily to three day changes to the overall pattern, but no significant wind or rain is shown outside of toward South Florida where some local flooding has occurred this morning and where moisture will be most prominent for several days.

Cape Canaveral Sun Rise Storm Approaches the Coast off the Atlantic

Mainly Showers and Some Isolated Thunder

Soupy and nearly stagnant low to mid level air mass under divergence well aloft should allow ample shower and some thunder formation today. Steering is very slow at 8-12mph (tops) , and with moisture over-loading in that slow motion would expect most storms not to move far from their source before weakening. Early evening cloud cover along much of the east 1/2 of the state is possible due to cloud debris accompanied by spacious sprinkles.

BEYOND: Little change into the weekend with rain chances decreasing some by later Sunday. Could be quite a bit of cloud cover for the Cocoa Beach Air Show, or less than pristine conditions for viewing certain elements of the show.

The earliest autumn since 1896 arrives this Saturday, September 22, at 10:49 A.M. (EDT). At this time, the Sun appears to cross the celestial equator from north to south.

Isolated Thunder Far East Central Portions Late Today

TODAY: Frontal boundary has moved little since yesterday and lower level winds have weakened a bit as a reflection of what will eventually happen to the boundary in the next 48 hours. Meanwhile, winds just above the deck are only a tad weaker today as opposed to yesterday but I expect they will weaken yet more as the day progresses. This should allow the east coast sea breeze to set up along the east coast, but make very little inland progress, maybe just toward US1 up and down the east coast except further south of West Palm Beach.

The best convergence will be near the front; however(!) - <gotta love ('howevers')>, it appears there is little in the mid-level moisture parameter north of I-4, and south of I-4 toward Melbourne is starting to dry out as well where convergence will not be as formidable for storm formation.

Conservative Approach to Shower and Thunder Coverage today, Possibly overboard
on the Strong Department Since any Strong Storms might be short lived. Strong due to wind gusts

Otherwise, the area that has cleared out since early day cloudiness is all but SE Florida, and with shorter days now in tow, this area might never realize enough destabilization for thunder. Drawn in is a Green zone, but this 'could' end up being thunder late today as well with a better chance of sea breeze collision away from the coast over the Glades. Otherwise, under the supposition there is a least a "side shore type sea breeze and up the intracoastals (but very light)", best convergence and upper level divergence will be along the east coast from Melbourne Beach and North under the drier mid-level air and thus stronger down draft Convective Available Potential Energy. With that said, some brief but strong wind gusts in the 38-50mph range are always possible near and east of I-95 mainly. Storms will move (assuming there are some after 4pm through 7pm) toward the ENE-E, and maybe work a bit ESE near Canaveral along outflows a tad slower than yesterday, but would anticipate that many roads across East Central will have another period of dreary dripping heading toward sunset, if only from showers.  All continget upon storm initiation/location  .

BEYOND: Thursday looks a bit similar to today with slower storm motions and better chances yet still of a sea breeze convergence. The front will sink just maybe a bit further south and continue to become more diffuse/indiscernible during the frontalysis process, while the upper level trough and winds remain positioned for SW flow aloft. Thus, chance of showers and some isolated thunder continues close to the surface to mid-level boundary, mainly Central and North Central .  

Continuing the road ahead, we're seeing only light onshore easterly flow and close to no- flow at the steering level, leading to a drifting inland shower regime with coastal showers also possible from the Cape and south to Miami. No change in temperatures,

Pattern Shift Has Begun - Showers and Thunder More Widespread Today Statewide

Sunrise on Monday, Cape Canaveral, Florida

TODAY: Long-awaited (for some) pattern shift has arrived. What is meant by 'pattern shift'? We have been under the influence, intoxicated by easterly flow (onshore east coast winds) for quite some time.  Today herald's a shift in gears to SW flow at the surface and aloft as a frontal boundary draped up and down the entire U.S. East Coast presses eastward across the far Northeast states southward well into the Gulf of Mexico. This could mean a warmer afternoon toward the east coast south of I-4, in particular, and far South Florida with delayed onset of rainfall chances. Rain and thunder is already occurring under the cloud cover shown in the satellite image (below).

Quite a bit of lightning is occurring over North Florida early this Tuesday morning. This area is under the best 'upper level wind dynamics' which weaken the further south one proceeds, especially south of Dead Central Florida toward the Big Lake of Okeechobee. Outflows from activity further north look plausible to move in over the region north of I-4, so that area might be a bit stabilized by "that 'air' " before full heating of the day (which is now earlier due to earlier sunset and later sunrise) can be 'realized', or come to fruition/occurrence. Therefore, watching further south.

TODAY: Some storms could be strong, but brief due to fast motion, toward the East Coast south of I-4. The only reasoning being is that outflow from earlier activity and increasing cloud cover further north might cut off destabilization (as noted in the above caption); whereas, further southward, better heating accompanied by a bit of divergence aloft (not really significant) under SW flow aloft which is quite moist could pile up some heavy rainfall in short periods accompanied by lightning strikes 'afrequent' (under the assumption thunder storms can develop there alongn the 'red zone' shown).  

The off setting 'proverbial fly in the ointment' is that the east coast sea breeze today does not look likely to develop except maybe briefly before the frontal boundary gets further Southeast ward (and slows down significantly tonight presumably) south of Fort Pierce.  Meaning,  1) no chance of low level convergence; and 2) this will not be a summer time/like rain chance regime today where sea breezes or Lake Breezes are the biggest player (except far south).

Latest KSC sounding is showing 23 kts of wind around 2000 ft which will at least try to mix to the surface, so would expect no sea breeze today, possibly unusually breezy along waters and lakes for this time of year from a SW direction. 

The 700mb temperatures are not cold at all, although 500mb temperatures are cool enough that water over-loading aloft could translate in cooler temperatures in to the mid-levels regardless, for gusty winds in and near heavier showers and/or thunderstorms. 

Either way, guidance is split on activity today with the NAM going extremely low key as it has been for three days now in regard to storms and even showers, with the GFS showing a good chance to likely  along the east coast from Melbourne or so, southward..toward Fort Lauderdale. The best chance of an east coast sea breeze is well south of the Lake, so it may be that area will end up with a big storm.

Overall though, the air mass over much of the peninsula south of I-4 is fairly uniform early today, so the driving factors for this afternoon into early - mid evening might be from outflows resulting for earlier activity further north working southward into areas where heating has built up. 

The down fall of this is that outflows without a conflicting sea breeze can act purely to stabilize the atmosphere. Unless a vorticity max comes through, today could be a big bust, but not willing to hedge bets on that one this early in the day. In short, today's post is a 'play it safe just in case post", and speak of the worst case scenario, which is good rainfall and thunder coverage working south after 1pm through early evening. And this stabilizing factor seems more likely near and north of I-4 and less likely along the east coast south of Ponce Inlet.

BEYOND: The frontal boundary is expected to wash out in the next 2-3 days across all of Central Florida in a wide swath, with the upper level trough never clearing the area (nor the true front)...rather, it gradually gets replaced after frontalysis by high pressure from the north without any drying of the atmosphere, followed by a light onshore flow re-asserting itself by later on Thursday or Friday. Either way, showers will remain with temperatures running about where they have been lately, either coming in off the Atlantic or inland showers and thunder.

The earliest autumn since 1896 arrives this Saturday, September 22, at 10:49 A.M. (EDT). At this time, the Sun appears to cross the celestial equator from north to south.

 Coupling Up For  the Cape Canaveral Sunrise

   

Isolated Thunderstorms Mainly From 4pm to Dark

Cape Canaveral Late Thursday, September 6, Thunderstorm

TODAY: Not much different than yesterday sums it up, with only a few conditions that point to less favorable for widespread thunder. Morning sounding, as expected, revealed warmer 500 mb temperatures now that the upper low has opened to a trough and is well east of the state. Additionally, steering is a meager 5-8 mph from the NW to WNW and the air becomes sharply drier about 10,000 ft.  up in the atmosphere.Thus, with only weak sea breezes along the east coast with the west coast sea breeze more than likely making greater headway, appears inland activity is possible along the larger Lakes especially Lake Okeechobee toward Ft. Pierce and on the South Side of the Lake and the South Side of Orlando eastward toward Seminole County and SW Volusia toward North Brevard potentially.

Outflows from even showers will likely be the next boosting mechanism since air aloft is still cool in the mid-levels which would give convergence along lake and those boundaries something for the atmosphere to play with. 

The issue today will be how much forcing there is upward to propel the column through the mid-drier level to big and great heights (strong thunderstorms). Making no mistake about, any said storm should it develop, will be able to produce frequent lightning, but as of the past two days I have not seen little  beyond the ordinary except toward Lake Okeechobee, and today the playing factors on those days are absent. 

But if so, it would be from Orlando/Sanford/Port St. John to west of Rockledge area and maybe southward toward US 1 to Melbourne. Did not really draw in specifics today as there is too much contingent upon 'additive'  mystery factors coming together to make a true hypothesis; point being rather to establish a framework dialogue describing what we are working with today rather than trying to strain a gnat. 

The other missing factor is upper level vorticity which was present along the east coast the past two days. It could still become a bit cloudy and 'drippy' anywhere along the east coast by late afternoon into the early evening though toward the east coast and inland areas where storms lay to bury and die out.

BEYOND: Above note the RED "L" in the image . This surface low formed in part from remaining energy associated with Isaac's Rotator cup. It is not expected to do a whole lot considering a frontal boundary will be giving it   Das Boot within about 48 hours toward the East to EastNorthEast as it it  can no longer dig its heals, being absorbed in a trough to move through the middle of the country (which will make for some cool mornings indeed - into the 40Fs in some locations in the wee hours). Speaking of which, I noticed Okeechobee City this morning was at 64F degrees before sunrise, and Vero hit a record low of 69F I believe it was yesterday morning. They were right around there before sunrise today as well.

IN any case, the frontal boundary will be sinking in to Central Florida around Monday now, and just exactly how far south the boundary will get is a bit more aloof, but the ECMWF and the previous GFS had it getting to the Florida straits. It might just take a little while longer to get there (if at all). Might even hang up toward Lake Okeechobee. 

But for the weekend, Saturday is not looking like such a big deal as far as rain goes as it appeared it would be, at least not for thunder. Very warm near the east coast though with delayed if any sea breeze north of Brevard. With all the sun and few clouds at the beaches and with Leslie loafing offshore, rip current threat is now reading "HIGH" from the National Weather Service so be advised of 'under toe out' and 'over head burnin'.'

FEW CHANCES FOR SCENES LIKE THIS NEAR THE BEACHES AFTER TODAY
IT APPEARS "SUMMER" STORMS WILL BE SOON DOWN FOR THE COUNT FOR 2012

Better rain chance on Sunday, but really does not appear all too impressive with no chance of a sea breeze and not real good forcing. mainly, rain chance on Sunday is well north of Lake Okeechobee...continuing into Monday Central and South Central.

Stronger Activity Possible Today Central Florida

September 4th, 2012 Storm Scapades - "Horizing Arising"
Arcus Cloud, Gust Front Formation 

TODAY: There is little change from yesterday's pressure pattern for the most part. An upper low off the east coast will lift north to north-northeast today and be located approximately 120 NM east of Cape Canaveral by mid-afternoon. Localize stronger winds aloft flow down its west side from the northeast across north rather than central Florida today, so as a result the best upper level divergence which was over South Florida yesterday will now be over Central Florida. Net result is that there is a minutiae of chance that stronger activity could be seen over Central as opposed to only South Florida as was the case yesterday (for the most part). Area to watch again near Ft Pierce toward the North side of Lake Okeechobee as well as far north possibly as Canaveral. Cold air aloft really never gets much further north than the Melbourne area though.  The net result of the better divergence could mean an early start to some showers as the east coast sea breeze begins between the beaches and Cocoa. If this earlier activity does take shape the chance of stronger activity later on might be nil due to stabilization of the atmosphere.  

Latest KSC morning sounding shows steering to be stronger than any model guidance indicates, with temperatures aloft cooler than yesterday as well. Thus, strong storms are possible today should nothing change later today from those conditions reflected in the sounding. Steering from the west about 10-14mph toward the east. Small hail also possible with gusts in the 35-48mph range in/near strongest storms.

Refer to  Numbered Captions in the Above Image

FRIDAY/SUNDAY: Weak low pressure area being watched for tropical development . Appears that feature no matter where it ends up or how strong in manages to gather wits (right now, not looking too likely) will have little time to strengthen before a frontal boundary and mid-level trough absorb it going into Sunday. Most guidance so far bring the strung out energy across mostly the North Half of the State, focusing it on Central Florida on Monday. Before that time though, the upper low to the east of the state will finally be released off to the northeast behind LESLIE...which will then allow the front and the old energy pocket from Isaac to swing through as the first cold front of the pre-fall Season. By Monday's night into early Tuesday. This will also mean that the cooler air aloft will move out, so the threat of strong storms could be over after today. 

This boundary is expect to clear south to at least Cuba or the Florida Straits followed by moist and brisk ENE winds for a few days, with cloudy periods and possibly some sprinkles. Temperatures in the low-mid 80Fs depending on cloud coverage. The boundary by or toward the following weekend could lift back north, or 'buckle back' ahead of another tropical disturbance from the South Central Atlantic which does not yet exist, per se. This would bring another shot of rainy weather toward the 15th or so of September with easterlies continuing . Thus, after this front clears out, the Wet Thunderstorm Season Door is Slammed shut for 2012 (not to say, thunder still cannot happen, nor that it still cannot be 'wet'). Referring only to the blanket "Typical Florida Thunderstorm" season as one might imagine it to be.

Isolated Storms, A few Strong Possible Later Today

 

TODAY: Having problems signing into my blog posting site today, thus,

this is a bit of a 'test post' attempt from email.

 

Tough call today, Wednesday, but all in all appears an upper

low off the SE Florida Coast is making for colder air aloft today

over the South 1/3 of the state and toward the east coast as far north

as near Melbourne. Steering is equally a tough call as it is divided in the

mid levels from WSW to the North. All in all, expect only slow storm motions today with propagation

along boundaries. Best chance of strong storms appears to be west of the Big Cities over South Florida

and just north of the LAKE on the north side of the Lake Shadow...this spells out the Ft. Pierce

to Vero Zone..with later activity as a result of outflows as far north as the Beach Line toward Rockledge/Port St John

areas of populace, whereas further west toward Orlando this is mainly swamp land and as far west as

Orlando might be west of the sea breeze convergence. Following images from Tuesday.

OTHERWISE: Remnants of the Seeds of Isaac (upper and mid level energy) is hovering

and will move little through tomorrow along the northern Gulf Coast. Perhaps be forced

a bit to the WSW off Southern Alabama as a result of the passage of Lisa to our east.

LARGE SWELLS in the offing, and dangerous high risk threat of rip currents

beginning today but more so ALL WEEKEND. Thunder chances

continue through the weekend as well.

I see the Hurricane Center is giving "Isaac" a 10% chance of something happening with it, but

so far this looks less likely over likely. Cannot say for sure, and bears watching, but all in all

what will come out of it for better or for worse is better rain chances for at least the north half of the state heading into Monday.

 

 

"Remnants of Isaac" to Revisit Florida By Friday/Saturday

"It is Best Not to Assume Too Much Responsibility in Areas We have no Control Over". Call it as one see's it...with a disclaimer.    

TODAY: Not much difference across Central from the past several days since the departure of Issac. It is possible though that as moisture increases slightly from South Florida and closes in from the North that we could see some thunder toward the Lake/Sea Breeze collision zone near Ft. Pierce and the surrounding area toward Lake Okeechobee north toward Vero, as well as north of I-4. Elsewhere, isolated too isolated to highlight. Otherwise, light winds. Overall, more activity across the state.

WEDNESDAY/THURSDAY: The mid level 'energy' (vorticity) from "Isaac's Ashes" very loosely speaking has already become well entwined with a synoptic scale trough and related surface front which is driving into the Southeast states after impacting the area from Arkansas, Missouri and other portions of the Mississippi River and Ohio River Valley basins, providing drought relief and some tornadoes. This energy is now being driven toward the southeast, so one could say at least in portion that "Isaac" is back to re-visit having gone full circle. In a larger sense, this is similar to what Ivan did several years ago as it went full loop out into the Atlantic and re-entried toward South Florida nearly 10 days after making its initial passage. 

"General" example of path of Ivan and Isaac and very general
forecast depiction in 'black'

In any case, increased moisture convergence along the trough with energy from the mid-levels ("Isaac" so to speak) will increase rain shower chances and some thunder mainly Thursday through Saturday, perhaps Sunday. Lack of a sea breeze  convergence except well east of the spine of the state should provide for a good day or two of storms until 'the remnants' move out into the Atlantic on the heels of by then what appears will be "Powerful Leslie" (hurricane) which is forecast to bring large swells and rip current threats up and down the U.S. East Coast.

FRIDAY-SUNDAY: Increased chance of showers and thunder with larger swells moving into the East coast. Rip Current/larger swells and lightning threat increases this weekend, beach goers over the weekend beware.

BEYOND: In the all in all, the thunderstorm wet season ended long ago before Isaac. Granted, some will assuredly argue the point, but tell us then "where are the storms?" 

The only reason we really are only going to have a chance now is from the frontal boundary and remnants of Isaac which is a far cry from the normal 'summer mechanisms' of sea breeze collisions in abundant moisturized and heat energized atmospheric environment one expects in a 'normal summer pattern', whatever that is. In the past 3 years, no two summers have been even close to similar although from an 'outside perspective' one could hardly say they can tell the difference.

The past two summers ..the wet season ended almost perfectly with the first day of Fall (September 21). This year looks far from that. That is not to say thunder is all but forgotten, but it will not be the norm any longer after this week. It might in fact, be quite sometime for any return of thunderstorms, as the boundary works eventually south (per the GFS) and onshore flow ensues, looking much more like an early Fall pattern, at least in the interim. That does not mean, however, the tropically related threat 'potential' does not continue to lurk well into October and early November.
