533 FXUS62 KKEY 050205 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1005 PM EDT Tue Jun 4 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1000 PM EDT Tue Jun 4 2024 A broken cumulus cloud line forming along the island chain struggled through the late afternoon hours, then gradually dissipated. This was likely a response to the surprising dry layer sampled in the 00z sounding at KEY between 950-875 mb. KBYX radar is generally void of any meteorological echo returns across the Florida Keys and the adjacent nearshore and offshore coastal waters. Seasonably muggy conditions are being observed across the island chain, with temperatures generally in the lower to mid 80s and dew points in the lower 70s. Given the aforementioned sampled dry air, elected to nudge measurable rain chances down to slight levels overnight. With the lack of large-scale forcing for ascent, any shower activity will generally be produced by any residual boundary interactions, which appear somewhat limited given the lack of convection this evening across South Florida. No other changes proposed for this late evening forecast update. && .MARINE... Issued at 1000 PM EDT Tue Jun 4 2024 No watches, warnings, or advisories are in effect for Florida Keys coastal waters zones. An Atlantic pressure ridge will extend westward across the southeastern United States over the next couple of days. As a result, gentle to moderate easterly breezes will persist, peaking during the afternoon and evening hours. Thereafter, the ridge will shift southward across Florida, resulting in slackening and, at times, variable breezes. The next upper level trough moves in starting Sunday will southerly breezes gradually freshening. && .AVIATION... (00Z TAFS) Issued at 1000 PM EDT Tue Jun 4 2024 VFR conditions will prevail at both island terminals through the TAF period. Rain and thunder coverage will largely be limited to any residual boundary collisions overnight, but dry low-level air sampled this evening suggests chances are too low to include mention in the TAFs at this time. Near-surface winds will remain out of the east at 8 to 10 knots. && .PRELIMINARY POINT TEMPS/POPS...
