DISCUSSION
Issued at 955 PM EDT Mon Mar 18 2024 Water vapor imagery highlights a Rex Block across the CONUS, although the 00Z RAOBs sampled rising heights within the cutoff low meaning the Rex may be breaking. At 925 mb, Slidell sampled a temperature almost 25 degreesC lower than Key West, and Freeze Warnings are in effect for the northern Gulf Coast. For middle to late March, this is a pretty good air mass gradient. Surface observations place a cold front over the eastern Gulf of Mexico and Central Florida. Northerly breezes are near Gale (28-33 kt) at the offshore oil platforms behind the front. The Keys remain in a little col region between the warm conveyor emanating from western Cuba, and the frontally forced convection dying out over the southeastern Gulf. The Cuban Boomers are happy near the coast, but seem to be struggling with the Cuban shadow (sampled by KEY)
lurking farther north in the Straits of Florida. The forecast calls for 30% rain chances overnight, which is notably below the MOS consensus. The main forecast challenge is assessing the moisture convergence between the percolating Cuban Boomers and the developing northwesterly breezes. By dawn, northwest to north winds will increase to near 20 knots, which should set up a good scenario for a broken line of convection over the Straits after midnight. Aside from introducing a Small Craft Advisory for the expected winds, we will hold at 30% rain chances as we expect the best convergence to be south of the island chain. No other changes are needed with the inherited forecast.

Issued at 955 PM EDT Mon Mar 18 2024 Small Craft Advisory in effect for all coastal waters of the Florida Keys due to north winds increasing to near 20 knots after midnight. Northerly breezes will freshen sharply tonight as a cold front pushes through the coastal waters of the Florida Keys.
Breezes will turn easterly and diminish Tuesday through Wednesday.
Unsettled weather at the end of the week will result in fresh to strong breezes Thursday night and Friday, followed by breezes shifting to the southwest then northwest at the tail-end of the unsettled weather.
AVIATION
(00Z TAFS)
Issued at 955 PM EDT Mon Mar 18 2024 The merging of a cold front with showers spreading northeast through the Straits of Florida will introduce a short window of VCSH at both terminals overnight. Forecast soundings suggest northerly crosswinds will reach 20 to 25 knots around sunrise, along with a brief period of TEMPO MVFR CIGS. Winds will shift east of north and decrease after 16Z.
