.KEY MESSAGES... Issued at 1003pm EDT Tuesday May 12 2026

- Rainfall moves out this evening with a drier pattern setting up into the weekend and early next week.

- Very warm temperatures expected this weekend with a high (70 to 90 percent) chance of temperatures exceeding 90 degrees. The heat may affect those who are sensitive, especially without cooling/hydration.

Issued at 1003pm EDT Tuesday May 12 2026

PoPs were adjusted to account for current radar trends across the region, rain chances continue to wind down and will continue to do so over the next several hours.

.SHORT TERM... (This Evening through Wednesday) Issued at 254pm EDT Tuesday May 12 2026

The upper level trough and associated surface low will move east through the remainder of the forecast area this evening and overnight. Widespread rain showers will move out with coverage steadily decreasing this evening and into the overnight hours. A few showers could stick around across the southeast Florida Big Bend into the early morning hours of Wednesday, but most of the area will begin to dry out by daybreak.

Northerly winds and drying conditions take over on Wednesday as the upper level system moves out. With more sunshine expected tomorrow, expect warmer temperatures as we climb into the low 80s.

Long Term
(Wednesday night through next Monday) Issued at 254pm EDT Tuesday May 12 2026

A drier and warmer pattern sets up across the area from Thursday into the weekend as an upper level ridge builds across the Gulf and southerly low-level flow returns. The beneficial rains from the last few days should help improve longer range fire concerns through at least through the next few days. The main story will be the first taste of typical summertime heat.

As the ridge builds expect highs in the mid to upper 80s on Thursday to climb to around 90 by Saturday and possibly into the low 90s by Monday and early next week. No rainfall is expected during the long term, but with flow becoming southerly, and conditions getting much warmer, it wouldn't be surprising to see a few isolated showers each afternoon late this weekend and into next week, but a broad widespread rain event is not likely in the next 7 days.

Marine
Issued at 254pm EDT Tuesday May 12 2026

East and northeast winds will range from 15 to 20 knots with seas building up to 3 feet tonight. Cautionary conditions will continue into tonight with improving conditions expected on Wednesday. Expect briefly higher winds and seas in the vicinity of any thunderstorms. A dry cold frontal passage Wednesday night into Thursday will bring northerly winds to area waters and then clock back around to the northeast Thursday night. Easterly winds will become onshore during the day Friday and Saturday within the seabreeze zone. Southerly winds return by late in the weekend and into next week with generally favorable boating conditions expected to continue.

Fire Weather
Issued at 254pm EDT Tuesday May 12 2026

Widespread rain showers will lift out this evening and into early Wednesday with drying conditions expected through the remainder of tomorrow. A frontal passage will then occur late Wednesday into Thursday bringing a reinforcing shot of drier air as well as a small increase in transport winds. With good post-frontal mixing and warm temperatures we'll likely see high dispersions along with sub 30% humidity for much of the area. Recent rains will help prevent larger fire weather concerns, but localized elevated concerns given longer term drought and the low RHs could not be ruled out. Sub 30% humidities remain possible again on Friday before southerly flow slowly brings low-level moisture back this weekend. However, no significant chance of wetting rains is likely from Wednesday into much of next week.

Hydrology
Issued at 254pm EDT Tuesday May 12 2026

Recent rainfall is not expected to cause river flooding. Rainfall amounts over the last several days have been beneficial for long- term drought, but we still have a long ways to go before a significant dent in the drought would occur. Looking ahead, a dry period of weather is in store through the weekend and into early next week.
