414 FXUS62 KKEY 171434 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1034 AM EDT Wed Jul 17 2024 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1033 AM EDT Wed Jul 17 2024 A mostly quiet morning for the Florida Keys. Dry air that was in place is slowing exiting stage left. This is being replaced with a relatively more moist air mass as seen on the GOES Total Precipitable Water satellite derived imagery. That being said, there is still dry pockets embedded not only in this moisture plume but in the mid levels as well. The morning sounding continues to show a stubborn dry layer present above the boundary layer to about 400 mb. This dry air is enough that shower coverage remains limited this morning. Given the recent radar trends and the persistent dry layers still present, see no need to deviate from the slight chance PoPs we have. Meanwhile, broad, expansive Atlantic Ridge will hold steady roughly centered near 30N, 50W and extend an axis well westward across the Florida Peninsula. This will maintain east to southeast breezes across the island chain. Dew points this morning remain in the upper 70s and we will have to monitor to see if we reach Heat Advisory Criteria for this afternoon. It`s going to be very borderline for today so make sure to take extra precautions if you are planning on being outside for an extended period of time. && .MARINE... Issued at 1033 AM EDT Wed Jul 17 2024 Atlantic ridging will remain across the Florida Peninsula through the forecast. This will result in gentle to moderate east to southeasterly breezes across Keys waters. Winds will tend to surge in the evening and night hours and lull during the day. Winds may strengthen this weekend as the ridge lifts northward into North Florida and the southeastern United States. && .AVIATION... (15Z TAFS) Issued at 1033 AM EDT Wed Jul 17 2024 VFR conditions will prevail at the EYW and MTH terminals through tonight with rain chances remaining below normal for this time of the year.
