Issued at 1030 PM EDT Sun Aug 31 2025 The wet weather pattern continues for yet another evening. A very early season mid latitude trough is balling up over the eastern United States. This has contributed to a surface trough draping southwestward across the Florida Peninsula and resulting light westerly breezes across the Keys. This has set up a very moist atmosphere spanning our area. Models suggest that despite the trough just to our north, the lower level flow in our area might have been less confluent than last night. This along with less support aloft may have helped to suppress overall convective intensity and coverage. With that said, we still saw scattered to numerous activity. The synoptic makeup of our weather is not expected to change overnight. The mid latitude trough will continue to congeal over the eastern United States and surface to lower level troughing will remain across Florida. Consequently, a broad zone of wet air, and more often than not, confluent flow will linger across and north of our area. Expect further rounds of showers and thunderstorms overnight. During quiescent periods, winds will be light out of the west. Overnight temperatures will range a bit due to rain effects, but be broadly in the lower 80s. Dew points will meander in the mid 70s. && .MARINE... Issued at 1030 PM EDT Sun Aug 31 2025 Surface troughing draping across Florida is responsible for mainly light westerly breezes on Keys waters this evening. This trough, along with copious moisture has been conducive to scattered to numerous showers across the broader area. These showers and thunderstorms have repeatedly perturbed surface flow with 20 to 30 knot wind gusts. No significant change is expected and the overall wet pattern will continue. The trough to our north will maintain light mostly westerly breezes overnight. && .AVIATION... (00Z TAFS) Issued at 1030 PM EDT Sun Aug 31 2025 A wet weather pattern persists across the area. As a result, while VFR conditions will prevail, bouts of sub VFR conditions are expected overnight. Away from convection, surface winds will be generally light out of the west to northwest. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
