137 FXUS62 KKEY 260241 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1041 PM EDT Tue Jun 25 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1041 PM EDT Tue Jun 25 2024 A couple reverse cloudlines across the Lower and Middle Keys got excited towards the late afternoon and early evening. In fact we saw two rounds of convection develop within these bands. The first band last about 2 to 3 hours and produced just under a half inch of rain at the Marathon Airport, an isolated thunderstorm, and a couple of waterspouts. Based on public report and images sent to us via social media, they developed across the Bay waters north of Marathon. The second round occurred just prior to sunset and produced a more robust looking thunderstorm that put out quite a bit of lightning strikes before eventually dissipating. For now the radar is quiet with decaying convection moving off south Florida towards Bimini and the Bahamas. Closer to home there are several ghost boundaries left over from earlier showers and storms. It remains to be seen how this will evolve overnight. Some of the hi-res CAMs show activity reinvigorating overnight as the flow slows down. While others show any resurgence in showers and potential thunderstorms staying offshore across the Straits of Florida. For now, given the uncertainty as to where things may re-fire, have maintained chance PoPs for the overnight. && .MARINE... Issued at 1041 PM EDT Tue Jun 25 2024 No watches, warnings, or advisories are in effect for the Florida Keys coastal waters. A weak ridge axis will extend westward from the western Atlantic across the Straits of Florida overnight through Thursday evening, with light to gentle southwest to west breezes prevailing over the Keys waters. Breezes may become variable at times during this period. The ridge will shift back northward late this week into the weekend, allowing gentle east to southeast breezes to resume. && .AVIATION... (00Z TAFS) Issued at 1041 PM EDT Tue Jun 25 2024 All is quiet for both airfields at this time. There is a chance that additional showers and thunderstorms may develop overnight however, exact timing and location remains uncertain. As such, will omit for now and leave for future amendments. Given the light southwest to west flow expected to continue into Wednesday (6/26) there the potential for another cloud line to develop within the vicinity of both terminals. && .KEY WATCHES/WARNINGS/ADVISORIES...
