549 FXUS62 KKEY 010254 AFDKEY Area Forecast Discussion National Weather Service Key West FL 954 PM EST Sun Nov 30 2025 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... -Slight rain chances are expected through tonight before tapering out of the forecast by tomorrow morning. -Generally gentle easterly breezes will continue through the next few days before turning around the clock Tuesday through Wednesday morning. These gentle breezes will maintain a northerly direction over the middle of the week. -An overall benign pattern of weather will remain in place through the week, but another front may try to approach the forecast area over the second half of the week. && .DISCUSSION... Issued at 954 PM EST Sun Nov 30 2025 The evening crew has had the pleasure of watching showers in the distant Florida Straits tapering off over the course of the evening, and our KBYX radar is now mostly clear of any rain besides a stray shower in the eastern Straits. GOES-19 Nighttime Microphysics is picking up on some low level clouds skirting across the skies, and the automated observations at both Key West and Marathon International Airports are picking up on a few clouds occasionally around 2000ft aloft. Other surface observations along the island chain show temperatures currently in the mid 70s with dew points just a couple of degrees lower than that. The air may feel a little bit sticky for this time of year, and that is courtesy of these prevailing easterly breezes. Some CAM guidance continues to show a light pop up shower, or two, possible for tonight, so will maintain the slight chance of rain currently advertised. The forecast is unfolding as expected, so no updates or changes are needed at this time. && .MARINE... Issued at 954 PM EST Sun Nov 30 2025 There are no watches, warnings, or advisories in effect across the Florida Keys local waters. From synopsis, high pressure across the New England region will progress further east through Monday and breezes will continue to slacken as well as shift to the east. Another high will take the place of this previous high for Monday night and early Tuesday keeping breezes gentle to moderate. A developing storm system on the heels of this high Tuesday will result in a weakening of the pressure gradient across the Keys through early Wednesday. Its corresponding cold front may try and push through the Keys mid to late week resulting in freshening north to northeast breezes. && .AVIATION... (00Z TAFS) Issued at 954 PM EST Sun Nov 30 2025 VFR conditions with easterly surface winds near 10 knots will continue through the TAF period. Weather is expected to remain dry, and any shower activity that does develop should be far enough away from both terminals to keep respective TAF packages dry. && .PRELIMINARY POINT TEMPS/POPS...
