446 FXUS62 KKEY 130329 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1029 PM EST Wed Nov 12 2025 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... -Moderate breezes will persist through the remainder of the week and into the weekend. -Temperatures will trend up to near or slightly below normal by the end of the week as high pressure, centered over the northeastern Gulf coast, weakens and stretches eastward into the Atlantic. && .DISCUSSION... Issued at 613 PM EST Wed Nov 12 2025 Mild conditions have returned to the Keys after the short lived burst of cold brought by the recent cold front. These conditions are being sustained by a surface ridge reaching far eastward into the Atlantic from the Gulf Coast. This high is driving gentle to moderate northeasterly breezes across the Keys this evening. Temperatures have recently slipped just below 70 at many island locations, likely helped some by much cooler bay water temperatures. No change to the synoptic makeup is expected overnight. Mainland cooling and cooler shallow waters will likely help to back winds north northeasterly across portions of the island chain. Latest observations already indicate this is occurring in some stretches. Expect overnight lows broadly to range broadly in the upper 60s to near 70. Dew points should meander near 60. Stable conditions will remain due to a sharp persistent frontal inversion based below 900 mb. && .MARINE... Issued at 613 PM EST Wed Nov 12 2025 High pressure centered over the southeastern United States extends a ridge increasingly further eastward into the Atlantic. This will maintain gentle to moderate mostly northeasterly breezes. The stronger breezes will tend to fall over the Florida Straits. That said, expect a subtle pickup in winds late overnight on waters in the lee of South Florida. && .AVIATION... (00Z TAFS) Issued at 613 PM EST Wed Nov 12 2025 VFR conditions will prevail at the island terminals through the overnight period. Surface winds will be gentle out of the northeast, potentially increasing to a moderate breeze late tonight. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
