Issued at 1030 PM EDT Sun Jun 29 2025 A surface Atlantic ridge extends westward across Florida, resulting in gentle to moderate easterly breezes across the Keys this evening. Meanwhile, an upper level Low is rolling slowly westward across the Bahamas. This has contributed to weakness in the lower level ridge and associated weak troughing aligned over the Bahamas. This evenings sounding indicated the Saharan dust is virtually gone. With that said, there was ample CAPE, limited inhibition based around 950 mb, and near normal precipitable water. Overall, the environment has been supportive of only a few showers and thunderstorms. Activity has tended to be small and short lived. Surface ridging will hold across Florida through the overnight period, keeping breezes mostly gentle easterlies. The lower level troughing, associated with the approaching upper level low, will remain off to our east through the night. Forecast soundings suggest lower level inhibition will persist. As a result, despite precipitable water climbing modestly, more than sufficient CAPE, and healthy boundary layer flow, activity should remain isolated. Skies will generally remain mostly cloudy thanks to copious cirrus wrapping around the upper lows western flank. Expect overnight lows in the lower 80s and dew points holding in the mid 70s. && .MARINE...
