607 FXUS62 KKEY 070237 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1037 PM EDT Fri Jun 6 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 937 PM EDT Fri Jun 6 2025 Deep layered ridging is resulting in very low rain chances across the Keys this evening. An Atlantic surface ridge stretches westward across Florida while the lower level ridge is nearly overhead. Meanwhile, the eastern Gulf is within the sharp descending half of a sloppy nearly cut off upper level low centered over Cuba. The ridging, with an assist from a Saharan Air Layer, is providing robust inhibition based just below 950 mb with significant dew point depressions through the lower levels and is effectively capping convection. Skies have been mostly clear with only shreds of stratocumulus. All convection has been located over the mainland and Cuba. Surface conditions are seasonably warm and humid with winds gentle to moderate out of the east to southeast. Expect ridging to remain in control of Keys weather through the overnight period. Surface ridging will maintain gentle east to southeasterly breezes and help to limit overnight cooling. Expect overnight lows in the lower 80s with dew points remaining in the mid to upper 70s. Forecast soundings indicate the base of the inhibition layer will lift to just below 900 mb. While chances will be quite slim, a strong boundary may be able to generate a weak shower. With that said, may update to remove first period PoPs. && .MARINE...
