DISCUSSION

Issued at 238 AM EDT Wed Sep 23 2026

The forecast for today will largely be more of the same, with light east and northeast flow keeping seasonably warm and humid conditions in place. A few showers may push into the southwest Florida coast from the Gulf during the morning hours, then scattered showers and storms will develop across the area in the afternoon. The pattern begins to change on Thursday as a deepening surface low off the Mid-Atlantic coast drags a weak cold front south and southwest through the Florida Peninsula. Increasing northeast winds along and behind the front will advect in a drier and slightly cooler air mass. As a result, rain chances on Thursday will be lower across the area, especially north and along the coast. By Friday, the drier air will have filled in across the entire area, keeping the entire area largely rain free through Monday. Otherwise, conditions should feel noticeably cooler and drier during the weekend, with morning lows in the low to mid 60s over the Nature Coast, and mid 60s to low 70s across the rest of the area. Afternoon highs will top out in the mid to upper 80s, but with dew points mainly in the 60s, humidity should feel a bit more comfortable than it has been recently.

By early next week, surface high pressure will start to settle south into Florida and the western Atlantic as the coastal low departs to the north. Southerly low level flow will gradually bring back moisture, with isolated showers and storms forecast for southwest Florida on Monday and isolated to scattered coverage across the entire forecast area on Tuesday. Temperatures and humidity will also gradually moderate back to near normal through the first half of the week.

AVIATION

(06Z TAFS) Issued at 238 AM EDT Wed Sep 23 2026
