...New UPDATE, AVIATION...
.UPDATE... Issued at 801 PM EDT Thu Sep 18 2025
Early evening water vapor satellite imagery is showing a drier air mass that has pushed south into the northern and central portions of the forecast area this evening, which kept rain coverage significantly lower than what was seen on Wednesday afternoon. A couple of showers are still lingering over southwest Florida, but these will continue to rapidly dissipate over the next couple of hours, with rain free conditions then expected through the rest of the overnight hours.
Some minor adjustments were made to the rain coverage forecast through 10 PM to keep up with radar trends. Otherwise, the forecast looks on track, and no other changes are planned for the evening update.
