UPDATE
Issued at 837 PM EDT Thu Mar 12 2026

Early evening radar imagery is showing a broken band of showers continuing to push south through southwest Florida, with rain free conditions filling in behind the line and expected to hold overnight. While almost the entire forecast area received some amount of the rain today, only a few pockets of around an inch or more of rainfall was observed, with the majority of the region receiving around a quarter of an inch or less.

The forecast looks on track overall, with drier air filling into the northern half of the forecast area for Friday keeping the rain chances generally over southwest Florida, then moisture surging back across the entire area this weekend with more widespread rain chances. A few minor adjustments were made to the rain chances for the next couple of hours to keep up with radar trends. Otherwise, no significant changes are planned for the evening update.
