.SHORT TERM & Long Term (This Evening through next Sunday) Issued at 151pm EDT Monday May 18 2026

Scattered showers and storms are beginning to develop over the Florida Panhandle early this afternoon. This should continue for the remainder of the day over mainly inland parts of the Panhandle into portions of southeast Alabama. Some of the storms this afternoon could produce strong wind gusts of 40-60 mph, locally heavy downpours, and frequent lightning. These will fade during the early to mid part of the evening with a warm and muggy night ahead. Lows area-wide will be in the upper 60s to lower 70s.

Tuesday through Thursday, there will be less coverage of showers and storms overall as strong ridging builds overhead and PWATs (Precipitable Waters) decrease a bit. Rain chances are at most around 20-30% each day. It will be very hot, however, by May standards. Highs will be in the low to potentially mid 90s for much of the area over the next 3 days with some areas seeing heat index values nearing 100 for the first time this year. This level of heat could affect those who are sensitive to heat, such as the elderly, those with chronic health conditions, or those without access to adequate cooling or hydration.

By late in the week into the weekend, the ridging will begin to shift a little bit more to the east as troughing nudges more into the Mississippi Valley and southern Plains. This will gradually pull in more moisture to our area with rain chances increasing heading into the holiday weekend. This would primarily be an increased chance of afternoon showers and storms. High temperatures will come back down to the upper 80s to lower 90s, but with the increased humidity, heat index values will still remain in the mid 90s to to low 100s. Lows remain near 70.

Marine
Issued at 151pm EDT Monday May 18 2026

Gentle to moderate east to southeast breezes continue over the next several days. The highest winds will generally be tonight with some areas approaching cautionary levels, especially over Apalachee Bay. Otherwise, tranquil boating conditions are expected to continue through the end of the week.

Fire Weather
Issued at 151pm EDT Monday May 18 2026

Generally southeasterly transport winds around 10 mph will continue each day, though the afternoon sea breeze will turn winds more southerly to southwesterly as it passes through. Dispersions will be good each day across the area. Isolated to scattered showers and storms will be possible along the afternoon sea breeze. Some of these storms may produce gusty, erratic winds as well as frequent lightning strikes.

Hydrology
Issued at 226am EDT Monday May 18 2026

Isolated to scattered storms will be possible each day through the next week. These could produce locally heavy downpours, which may lead to some nuisance flooding, mainly in urban or poor drainage areas. However, widespread flooding concerns are not expected.

Extreme to exceptional drought continues across the area. While the rain is beneficial, significant improvement in drought conditions is not expected. For more information on local drought impacts, please visit www.weather.gov/tae/DroughtInformationStatement.
