633 FXUS62 KKEY 121430 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1030 AM EDT Wed Mar 12 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1030 AM EDT Wed Mar 12 2025 It is an absolutely GORGEOUS Wednesday morning across the Florida Keys. KBYX is not detecting any shower activity and GOES 16 Visible satellite imagery shows some fair weather cumulus clouds over the Straits of Florida with otherwise abundant sunshine throughout the area and practically the whole state of Florida for that matter. Temperatures along the Island Chain are on the cool side of things with most locations observing mid to upper 60s this morning. A few locations were observing lower 70s namely Big Pine Key RAWS. Dew points are also still on the lower side of things ranging from the upper 40s to the upper 50s. Surface high pressure remains centered over Florida this morning. As a result, marine platforms around the Keys are observing north to northeast breezes of 5 to 10 knots with Island Chain communities observing 5 to 10 mph. .SHORT TERM FORECAST... The 12z morning sounding displays a very dry profile. The PWAT value measured was 0.48 inches which is below the 10th percentile for the date and not too far away from the min for the date. The wind profile shows a slight veering profile with north to northeast breezes near 10 knots around 1000 ft AGL becoming northeast around 3000 ft AGL. All this to say, no changes expected with the morning update. && .MARINE... Issued at 1030 AM EDT Wed Mar 12 2025 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure centered over the central Gulf will slide eastward through the rest of the work week. Light to gentle breezes will respond, veering from the north to northeast this afternoon to the southeast by Thursday. A second, stronger high will build in the western North Atlantic and interact with a developing area of low pressure in the central United States, supporting freshening southeasterly breezes for Friday night through early Sunday. As the front approaches the Keys marine zones late Sunday, breezes will once again briefly slacken. && .AVIATION... (15Z TAFS) Issued at 1030 AM EDT Wed Mar 12 2025 VFR conditions will prevail at both EYW and MTH through the TAF period. Limited cloud coverage and near nil rain chances are expected through the afternoon. North to northeast winds will become variable and light this afternoon. && .PRELIMINARY POINT TEMPS/POPS...
