954pm EDT Sunday August 23 2026

Issued at 950pm EDT Sunday August 23 2026

The only changes of note to tonight's forecast were to introduce mentionable Probability of Precipitation for a decaying thunderstorm cluster pushing south across Apalachee Bay and adding "patchy fog" to the point-and- click weather grids for parts of the Eastern FL Big Bend into the I-75 corridor. Some isolated showers may develop some tonight later tonight near the AL Wiregrass into the Western FL Panhandle thanks to the presence of a lingering frontal boundary.

.SHORT TERM... (This Evening through Monday) Issued at 322pm EDT Sunday August 23 2026

An Storm Prediction Center Marginal Risk (level 1 of 5) for severe storms remains in effect for the rest of today into the evening. Although a watch is not anticipated, low level lapse rates and PW will be sufficient in a northwest flow regime to allow for wet microbursts to produce marginally damaging winds in isolated storms through this evening. A stalled front to the north and existing outflow boundaries are potential triggering mechanisms.

Coverage of storms will increase on Monday and another SPC Marginal Risk for severe storms is already in place due to the continued combination of a northwest flow regime, deep moisture and low level instability. A WPC Marginal Risk (level 1 of 4) for excessive rainfall is also in place.

Uncertainty in timing of development of convection and associated cloud cover precludes the issuance of a heat advisory at this time, especially considering how the current advisory is not panning out. However, forecast heat indices currently support one for our FL counties as well as South GA from Lowndes County east along the FL border to Lake Seminole. The overnight shift will reassess.

Long Term
(Monday night through next Saturday) Issued at 322pm EDT Sunday August 23 2026

Tuesday and Wednesday will be carbon copies of Monday with Storm Prediction Center and WPC marginal risks in place. Heat advisory criteria does not appear in jeopardy. Rain chances will increase for Thursday and Friday as a front approaches from the northwest. Near normal rain chances and temperatures are forecast for the weekend.

Marine
Issued at 322pm EDT Sunday August 23 2026

Gentle to occasionally moderate southwesterly flow will continue over the waters for the next several days. Scattered showers and storms are possible each day, mainly in the overnight and morning hours, decreasing in the afternoon. The main exception will be for any clusters of storms that move off the coast this week during the late afternoon or evening hours. Seas will remain around 1 to 2 feet.

Fire Weather
Issued at 322pm EDT Sunday August 23 2026

Generally light west to southwest transport winds will continue through the next several days. Dispersions will remain good overall each afternoon. Increasing coverage of storms are expected Monday and Tuesday. Gusty, erratic winds and dangerous lightning strikes will be possible.

Hydrology
Issued at 322pm EDT Sunday August 23 2026

There is a WPC Marginal Risk (level 1 of 4) for excessive rainfall across the region from Monday through Thursday. Storms could produce locally heavy rainfall over the next several days. If the storms are slow- moving, then they could produce several inches of rain in a short period of time. This would lead to some nuisance to isolated flash flood concerns, particularly in low- lying or poor drainage areas. River flooding is not expected.
