145 FXUS62 KKEY 040252 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1052 PM EDT Thu Jul 3 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 923 PM EDT Thu Jul 3 2025 Persistent troughing over the eastern United States has resulted in the formation of a weak low centered over northern Florida. This has helped to keep an Atlantic ridge displaced eastward of our area and resulting in light and varying breezes across the Keys. The Keys are just within the lower level cyclonic flow around the developing low. this has resulted in very moist conditions with this evenings sounding indicated 2.21 inches of precipitable water. In addition, weak confluence has moved in through the lower levels. However, surface forcing is quite limited. After an afternoon of reverse island cloud lines, activity has diminished significantly. Winds will remain quite light through the overnight period with a col remaining roughly in the Florida Straits. Deep layered moisture and lower level troughing will remain across our area. With that said, the weak surface kinematics and lack of upper level support should help to keep PoPs in the chance range. Expect overnight lows broadly in the lower 80s with dew points in the mid 70s. && .MARINE... Issued at 923 PM EDT Thu Jul 3 2025 The combination of a weak low centered over northern Florida and the Atlantic ridge off to the east will result in light breezes across Keys waters overnight. Most waters will see winds back from westerly to southwesterly. More variability is expected over the Florida Straits. && .AVIATION... (00Z TAFS) Issued at 923 PM EDT Thu Jul 3 2025 VFR conditions will prevail at the island terminals overnight. With that said, there will be a chance of sub VFR conditions due to expected scattered showers. A thunderstorm cannot be ruled out. Surface winds will be light out of the west, shifting southwest. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
