A large gale centered off the SE coast will generate a brisk and steady NW flow across FL overnight. Strong subsidence inversion on the backside of the gale has trapped between 0.75"-1.00" of precipitable water below the H85 lyr as noted by the 17/00Z RAOBs. Latest IR sat pics shows a large ST/SC deck over FL extending well into south GA...wrap around moisture assocd with the gale. Surface obs measuring cigs generally 1,000-1,500FT across central and north FL. Abv the inversion, airmass is bone dry with H85-H50 average dewpoint depressions between 15-20C.

Nil precipitation chances tonight as depicted in the current grids. Coolest night of the season on hand overnight as the cold air advection generated by the NW flow pushes min temps into the M/U40s along and north of I-4, and into the L/M50s over the Treasure Coast/Lake-O region. Update will primarily address sky cover, which will need to be increased based on latest satellite trends.
