| Area Forecast Discussion ...UPDATED National Weather Service Key West FL 136pm EDT Tuesday April 14 2026 Issued at 959am EDT Tuesday April 14 2026 High pressure centered between the Atlantic Bight and Bermuda supports fresh northeast to east breezes across the Florida Keys this morning. Dewpoints are in the upper 50s to near 60, making for a relatively comfortable mid-April morning. The 12Z KKEY RAOB sampled a 6.0 degC inversion near 820 mb, with a shallow mixed layer barely capable of small patches of drizzle. The forecast calls for slight rain chances (10% or less) and highs in the lower 80s. The only needed modification this morning was an update to the Fire Weather Forecast that highligheights moderate Fire Danger Risk and 20 ft winds greater than 15 mph. With dewpoints in the upper 50s, some areas may see RH values fall into the upper 30s. Marine Issued at 959am EDT Tuesday April 14 2026 A high pressure system over the central North Atlantic will maintain fresh northeast to east breezes. Occasional fast- moving light showers cannot be ruled out, especially in the overnight periods. Breezes may briefly lull during the late afternoon and early evening across the Gulf waters due to the heating of South Florida. As the high moves farther eastward and slowly weakens, easterly breezes will modestly slacken for Thursday and Friday. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...Small Craft Advisory until 5pm EDT this afternoon for GMZ052>055-072>075. |
