Wind Chills Saturday Night with near Record High Minimums During the Day?


TODAY: Frontal boundary located across Central Florida pressing slowly south during the late morning to mid afternoon with much drier air and hence clearing skies in it's wake as the day wears on. 

There is sufficient low to mid level moisture though for some clouds once the sun gets working on the atmosphere, so not expecting an entirely CLEAR day but for perhaps later in the day. Temperatures to hover mainly in the mid-upper 70Fs to near 80F especially South Central/South.

Halloween Cat Scratch Fever

HALLOWEEN NIGHT: Cool and clearing with temperatures lowering from low 70Fs into the lower to mid 60Fs by around 10pm. Otherwise, very pleasant.

It is the next front that is the 'hum-dinger of Daddy Fronts' to come across Florida early Saturday that is going to have something to say though.

SATURDAY: After morning lows occur mainly in the mid 50Fs Saturday morning with lower 60Fs limited to the immediate beachside residents, the next front will glide invisibly across with increasing winds on its heals. Strong low pressure will be forming just off the coast of the Carolina s with a strong anomalous mid-level jet aloft of 110 Kts across North Florida and 10,000 foot level winds across Central Florida of 70 + kts as high pressure dives south through the lower Mississippi River Valley Basin. 

This is an extremely unusual set up any time of year  esp. this time of year. With 2000 foot level winds showing to be around the 35 kts mark, with heating of the day atop strong cold air advection, wouldn't be surprised if we might see some winds gusts near 40 -42mph on Saturday afternoon, but more likely in the 25-38mph range.  

The next factor will be to mix the temperatures in. Afternoon highs as noted the other day might not crack 60F parts of North Central Florida. 60Fs looks for Central parts of Central and south to South Florida..but where to draw the line of 60F and below has been wobbling north/south somewhere across Central. Either way, it's going to be very dry, very windy, and unusually cool for what we've been used to. Not a good day for boating by any means.

SUNDAY: Wind chills overnight?! Last NAM is coming in showing upper 30Fs to just inland of Vero Beach and across almost all of the west side of Orlando toward Ocala, whereas the GFS implies closer to low 40Fs along the 27 Corridor and mid-40Fs elsewhere. 

There could be a huge temperature gradient (difference in temperature) between the IMMEDIATE BEACH side east of A1A Sunday morning from anywhere to the west toward US1 and then I95. West of I95 is guaranteed 40Fs and near US1 looks close to upper 40Fs, with the sand shores east of A1A from the Cape South   perhaps in the lower 50Fs, with a continued breeze but decreasing just a bit and shifting to NNE.

Noting that most of the U.S. along and east of The Mississippi River will be in the 30Fs Sunday morning save parts of Florida and the eastern parts of the Carolinas likely because there will be some cloud cover and perhaps precipitation.

Sunday to 'warm' to the mid to 'maybe' upper 60Fs many areas by near noon to late morning though and thus endeth the cold spell for the beaches from the Cape and south. Overnight lows continue toward upper 40Fs to lower 50Fs as winds might decouple a bit after dark inland, but remain just strong enough to actually never fall much after dark at the beach near the A1A strip mainly.

MONDAY - BEYOND: Beaches to wake up to mid-upper 60Fs but remaining cooler well inland with highs in the mid 70Fs and from there on out the beaches will be in the 70Fs 24/7 through the end of the week. Deeper easterly winds with time could advect and dense low level cloud deck across the east coast and into the interior Tuesday through Friday with some sprinkles perhaps possible at the immediate beaches region mainly with probably no measurable totals if any falls at all. 

Cloud cover if it does manifest though as it looks like it could might actually hold afternoon high temperatures down, but then again, keep over night lows warm (hence in part, round the clocks 70Fs).
