| Area Forecast Discussion National Weather Service Key West FL 1053am EDT Wednesday Mar 25 2026 Issued at 1053am EDT Wednesday Mar 25 2026 The Keys lie beneath a messy and fractured mean low-level ridge. This ridge is fragmented into essentially three elongated (west to east) pieces. We lie on the eastern periphery of the middle section, which is maintaining a northeast to east wind across the island chain today. This fractured state is also why our winds have been peaking overnight and then lulling during the late morning and early afternoon hours. That pattern will not change this afternoon and expecting the same thing to occur. Meanwhile, this persistent low level ridge continues to provide a capping subsidence inversion across the region with very dry in the low to mid levels of the atmosphere. As such, this will continue to suppress rain chances and keep most clouds at bay for today. Temperatures are on track to reach once again to near 80 degrees this afternoon. Therefore, saw no need to make any changes for this forecast update cycle. Marine Issued at 1053am EDT Wednesday Mar 25 2026 Gentle to occasionally moderate northeasterly breezes will prevail into the afternoon. Across the nearshore waters north of the island chain, breezes may briefly slacken to light to gentle this afternoon but return to gentle breezes this evening. High pressure across the region will gradually slide eastward into the Atlantic over the coming days. This will allow for breezes to gradually freshen ahead of the next approaching cold front. This front is slated for late Saturday into Sunday with fresh to strong breezes expected in the wake. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
