163 FXUS62 KKEY 132011 AFDKEY Area Forecast Discussion National Weather Service Key West FL 411 PM EDT Wed Aug 13 2025 ...New AVIATION, MARINE, PREV DISCUSSION... .AVIATION... Issued at 305 PM EDT Wed Aug 13 2025 VFR conditions will prevail for the 18Z TAF period at EYW and MTH. Short lived bouts of VCSH to possible VCTS cannot be ruled out, but are not forming with enough consistency to warrant a TEMPO group. Outside of showers, winds will remain southeasterly from 5 to 10 knots. && .MARINE... Issued at 1015 AM EDT Wed Aug 13 2025 No watches, warnings, or advisories are in effect for the waters surrounding the Florida Keys. From synopsis, a broad ridge stretching across the North Atlantic westward to the Florida Peninsula will result in light to gentle east to southeast breezes for the rest of the week through the weekend. Rain and thunder chances will be near to below normal for this time of year, tending to peak in the late overnight and early morning hours. && .PREV DISCUSSION... Issued at 305 PM EDT Wed Aug 13 2025 A surprisingly quiet pre- sunrise period led to nearly cloud free skies across the Florida Keys. Returns from the KBYX radar show mostly non-meteorological echoes across the waters, and GOES-E Day Cloud Phase microphysics images depict shallow, sparse cumulus clouds over the Straits. The morning KKEY 12Z sounding measured a few layers of CIN above the boundary layer with a PWAT near 2 inches, about halfway between the 50th and 75th percentile for the day. Zooming out to the synoptic view, 500 mb heights rose slightly over the past 12 hours and satellite water vapor observations show a weak westward- moving TUTT north of the Yucatan. All indications suggest drier, ridging conditions will prevail today and tonight. Potential hazards for the day will revolve around heat, because heat indices up to 108 F are possible.
