738 FXUS62 KKEY 111455 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1055 AM EDT Mon Aug 11 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1047 AM EDT Mon Aug 11 2025 A lingering moisture surge, coupled with modestly freshened and veered boundary layer winds, have promoted more than expected scattered shower and isolated thunderstorm coverage this morning. Given radar trends, elected to nudge measurable rain chances to high-end chance levels for the first period, with many island communities receiving over a tenth of an inch of rainfall. Looking upstream in the eastern Straits of Florida, shower coverage appears to be much more limited, as dry air sampled in satellite- derived total precipitable water products continues to filter towards the Keys. The forecast calls for waning rain chances after the early afternoon hours. Although temperatures will take a bit to rebound, ample late afternoon solar insolation should provide a window for temperatures to quickly climb to the upper 80s again today. Other than the aforementioned nudge upward in PoPs, no other changes proposed for this late morning update package. && .MARINE... Issued at 1047 AM EDT Mon Aug 11 2025 No watches, warnings, or advisories are currently in effect in the Florida Keys waters. From synopsis, an Atlantic Ridge will continue to build westward and across the Keys. This will result in gentle to moderate east to southeast breezes over the next couple of days. The ridge will buckle briefly mid week, allowing for breezes to slacken temporarily. Breezes freshen to gentle to moderate once again towards the end of the week. && .AVIATION... (15Z TAFS) Issued at 1047 AM EDT Mon Aug 11 2025 Scattered showers and isolated embedded thunderstorms will remain in the vicinity of the terminals through the early afternoon hours. A general mention of VCSH is included in the TAFs for now, with specific impacts to be left to possible short-fused amendments and TEMPOs. Near-surface winds will remain out of the east to southeast, modestly freshening after 18z. && .PRELIMINARY POINT TEMPS/POPS...
