Issued at 1030 PM EDT Sat May 25 2024 Currently - A surface through lower level Atlantic ridge stretches westward across South Florida and the Keys this evening. This along with day time heating has resulted in light and variable breezes across the Keys. Despite a subtle shortwave trough riding around a gulf upper level ridge, stable conditions remain in the Keys. This evenings sounding indicated quite a bit of drier air through the lower levels and a fairly strong inversion based around 800 mb. As a result, while shower and thunderstorm activity was quite a bit more rambunctious over South and Central Florida compared to yesterday, the Keys and southern South Florida have been essentially quiet. Near seasonable conditions are in place with temperatures coming down through the lower and mid 80s with dew points in the lower 70s. Short Term Update - Guidance suggests that the previously mentioned trough will brush the Keys later in the night. However, it is not expected to have any impact. Moisture will remain limited and the troughs influence will be insufficient to wipe out the lower level inhibition. In addition, lower level forcing will be limited. As a result, will keep PoPs out of the overnight forecast. The surface ridge will remain across South Florida and the Keys. This along with dissipating day time heating effects will result in winds becoming a broad southeasterly. Expect overnight lows to range quite a bit from the upper 70s to lower 80s due to some early radiational cooling. && .MARINE... Issued at 1030 PM EDT Sat May 25 2024 Atlantic ridging across South Florida and the Keys will result in light broadly southeasterly breezes tonight. Expect some initial variability due to the lingering effects of day time heating on the mainland. && .AVIATION... (00Z TAFS) Issued at 1030 PM EDT Sat May 25 2024 VFR conditions will prevail at the island terminals.
