242 FXUS62 KKEY 170231 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1031 PM EDT Fri Aug 16 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1030 PM EDT Fri Aug 16 2024 Currently - Its been a wet evening for much of the Keys this evening. This can be attributed to the combination of copious lower level moisture, weak steering currents, and island cloudline and mainland boundaries. On top of this, high pressure building southwestward across Florida and the Gulf is driving an incoming prevailing light to gentle easterly flow which is enhancing lower level confluence across our area. MRMS indicated over six inches of rain over portions of the Florida Bay while many island locations received one to two inches. Activity is finally winding down but a few locations near Long Key continue to receive moderate to heavy rain. Thanks to the rain and late afternoon cloud cover, temperatures are already well into the lower 80s for much of the Keys with dew points still steamy in the upper 70s. Short Term Update - Ridging across Florida and the Gulf Coast will remain in control of our winds through the overnight period. Winds will remain light to gentle and broadly out of the east. This flow will do little to dislodge the moisture axis as this axis runs east to west and the lower level steering flow remains nebulous through. Expect shower activity to continue to wane in the near term but is expected to pick up again late in the night as the boundary layer recharges and new boundaries move in. Expect overnight lows in the lower 80s with dew points generally remaining in the upper 70s. && .MARINE... Issued at 1030 PM EDT Fri Aug 16 2024 High pressure spreading southwestward across Florida and the Gulf of Mexico is reestablishing light mostly easterly breezes on Keys waters this evening. These easterly breezes will then persist through the night. Only minor adjustments made in the evening marine update. && .AVIATION... (00Z TAFS) Issued at 934 PM EDT Fri Aug 16 2024 VFR conditions will prevail at the island terminals overnight. Surface winds will be light and broadly out of the east. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
