Issued at 1100 AM EDT Mon May 13 2024 CIMSS satellite-derived vorticity analysis highlights a well- defined mid-level ridge bridging the Gulf of Mexico and South Florida. The 12z sounding at KEY reflects this feature, with a mixed layer up to around 975 mb, and then a series of thermal inversions above. KBYX is void of any meteorological returns at this late Monday morning hour, which will continue through this evening. The main weather story for the day is the heat. Temperatures are already in the mid 80s across the island chain. Combined with dewpoints in the mid to upper 70s, it feels like the upper 90s to near 100F at most communities. Temperatures will likely top out in the upper 80s to near 90F by this afternoon. Stay cool, Florida Keys. && .MARINE... Issued at 1100 AM EDT Mon May 13 2024 An area of high pressure will slide over the western North Atlantic, resulting in generally gentle to moderate southeast to south breezes for much of the week. A brief bout of moderate to fresh breezes is also possible tonight through Tuesday morning.
