Area Forecast Discussion National Weather Service Key West FL 1120 PM EDT Sun Jun 14 2026 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... - Island cloud line formation will be possible in the late morning or early afternoon hours through Tuesday. - Water levels will approach Coastal Flood Statement thresholds in the Lower and Middle Keys around the time of high tide on Monday through Wednesday. - Conditions will remain seasonably warm and muggy, with heat indices approaching near 100F each afternoon through early next week. && .DISCUSSION... Issued at 1120 PM EDT Sun Jun 14 2026 Another summer night for the Florida Keys. Temperatures in the mid 80s and dew points in the mid 70s making it feel muggy once again. A few boundaries are moving through the CWA occasionally sparking off a few light showers but as of now the island chain has not seen any impacts from those. Along the Reef, marine sites are reporting light southeasterly breezes of 5 knots or less. The rest of tonight is expected to go similarly to what we have been experiencing muggy, slight chances of showers, light southeasterly breezes. No changes were needed for tonight's update package. && .MARINE... Issued at 1120 PM EDT Sun Jun 14 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, with a weak high pressure system centered in the North Atlantic, light to gentle breezes will persist through the middle of the week across the Florida Keys coastal waters. The interaction of the high with a stationary front draped over the Mid-Atlantic will support generally southerly winds. The high will strengthen after Tuesday night, supporting modestly freshened breezes for the latter part of the work week. Shower and thunder chances are on track to remain very low through the forecast period, largely limited to the nearshore waters off the Lower Middle Keys in the late morning and early afternoon hours with island cloud lines. && .AVIATION... (00Z TAFS) Issued at 1120 PM EDT Sun Jun 14 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. Mostly dry night expected so no mentions of VCSH at this time. Near surface winds will continue to be light and southeasterly. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
