557 FXUS62 KKEY 081435 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1035 AM EDT Mon Jul 8 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1034 AM EDT Mon Jul 8 2024 A very quiet but muggy start to the day across the Florida Keys. Substantial dry air is moving into the region as noted in our sounding this morning between 850 and 650 mb. This dry air is the leading edge of a Saharan Air Layer that is working it`s way westward across the Lesser Antilles and Bahamas. This unsurprisingly has shut down almost all rain chances. Currently KBYX radar shows no precipitation echoes in our immediate vicinity. Satellite representation is a a little different. It would seem that as the leading edge of the dry layer approaches, a mid deck of clouds has sprouted but this will be brief. The lack of clouds, a light southeasterly wind, and dew points in the upper 70s will lead to heat indices between 108 and 112 degrees today. As such a Heat Advisory remains in effect for the Florida Keys. Extra precaution should be taken today to reduce the risk of heal-related illnesses. With the dry air in place, near nil rain chances will persist through the remainder of the day. Therefore, no changes needed at this time. && .MARINE... Issued at 1034 AM EDT Mon Jul 8 2024 No watches, warnings, or advisories are in effect. Gentle to occasionally moderate southeasterly breezes will slacken through this afternoon. High pressure will build westward across the Florida Peninsula and into the Gulf tonight through the rest of the week, bringing gentle to occasionally moderate easterly breezes to the Keys waters for Tuesday through Friday. && .AVIATION... (15Z TAFS) Issued at 1034 AM EDT Mon Jul 8 2024 VFR conditions will prevail at both island terminals, as rain chances today and tonight are slight at best.
