Fall - Phase I - Has Arrived?

(this image shows some kind of "boundary" aloft passing over the aparment stretching east-west)
If a water vapor image tells a thousand words, then the old phrase holds true. Much drier air aloft is already overhead, and even drier air resides in extreme North Brevard knocking at our door. At the surface, the dewpoint has dropped below 70 degrees for the first time in who knows how long (I would probably suffice it to say since April though as a wild guess...or maybe early May).

All in all, today will be a dry one with no change in the ambient outside air temperatures. After sunset and into early Tuesday morning it will be the very immediate coast that will notice the change with the drier air and a light westerly wind component. As of shortly before noon today the wind even veered to the NW, an indication that indeed a front has passed. It currently resides from a Palm Beach to Ft. Myers line and probably won't make it much further south during the day. And yet another front is waiting on its heels for post-noontime tomorrow. This will be the second half (Phase II) of falls arrival with an accompanying drop in temperature as well.

The models are continuing to show a chance of rain to accompany the second front after noon tomorrow along the central east coast, but as of now I have extremely low confidence of any such animal to make an appearance. Most likely what is showing as precipitation by the models will manifest itself as a band of short lived mid-level cloudiness.

Open the windows Tuesday night before going to bed because unless one likes it really REALLY cool inside with the A/C cranked up it should be cool enough for the meekest of souls to bear. I'm holding true to yesterday's temperature forecast other than it's possible that everyone other than those living within 3 blocks of the beach will fall below 70 degrees. Coldest temperatures will be on the west side of the state from Punta Gorda north, especially 5 miles or more away from the Gulf of Mexico. The warmest morning lows in the state will be found along and east of A1A from Cape Canaveral south.
Looking into the future a bit, we can rest on our haunches for a while as far as anything spectacular weather wise to occur. At least until Saturday. The local air mass will undergo a very slow modification starting Friday with no more fronts poised to impact us until at least early NEXT week...if even that. Often these first fronts are more like a friendly gesture to remind us the summer is over, but fall still has some biding to do..but don't forget 'it'...because sure enough it will be here for the long haul sooner than you think!
