Late this weekend, winds will once again freshen as the next cold front pushes through the Keys. -The next opportunity for showers is sometime over the Saturday to Sunday timeframe. && .DISCUSSION... Issued at 506 AM EST Thu Dec 11 2025 KBYX is finally experiencing some relief since it has been rain- free all night. Though not shower related, Nighttime Microphysics does depict mostly cloudy skies for the region. Across the island chain temperatures cooled to the mid to upper 60s. Winds along the Reef are 10 to 15 knots. For today, winds are expected to slacken, and dry conditions will prevail as high pressure dominates our present weather. Not much is to change over the next few days, but as the high eventually goes into the western North Atlantic, winds will go from north to northeast back to northeast to east. The next front is expected to move through the Keys Sunday night into Monday morning and as a result breezes will become fresh to strong. For Monday and Monday night, Small Craft headlines may be required as winds are expected to reach those conditions. While winds will peak Monday night behind the front, they will remain elevated before gradually slackening later the work week. Prior to this frontal passage, Saturday night and Sunday will experience an uptick in rain chances. Once again dry conditions will return after the front has made its way through. && .MARINE... Issued at 506 AM EST Thu Dec 11 2025 No watches, warnings, or advisories are in effect for the Florida Keys waters. From synopsis, as high pressure drifts eastward over the next several days and eventually into the western North Atlantic, winds will clock around to the north to northeast, then eventually northeast to east. The next frontal boundary is progged to push through the Florida Keys marine zones on Sunday night, with fresh to strong northeasterly breezes expected in the wake of the frontal passage. && .AVIATION... (06Z TAFS) Issued at 506 AM EST Thu Dec 11 2025 VFR conditions are expected to prevail at the terminals through the TAF period. While observed cloud bases have generally remained below FL030, coverage has been largely SCT or less, and satellite imagery shows a lessening coverage trend, so dips into MVFR CIGs are still possible, but not anticipated. Northwest to north winds will gradually veer over to north to northeast by this afternoon. && .CLIMATE... On this day in 1962, the daily record cold high temperature of 60F was recorded at Key West, and 62F at Marathon. Temperature records for Key West date back to 1872, and for Marathon to 1950. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
