James Spann: Wind, rain for Alabama tonight; severe storms possible near the coast



WINDY, WET NIGHT AHEAD: A dynamic weather system will bring widespread rain to Alabama tonight, along with strong gradient winds unrelated to thunderstorms. There is a possibility that unstable air could enter the southwest corner of Alabama, and the Storm Prediction Center maintains an increased risk (Level 3 of 5) of severe thunderstorms for areas south of a Millry to Brewton line.

GRADIENT WIND: It’s important to note that while the core severe thunderstorm threat is limited to the southwest corner of Alabama, the entire state will experience strong gradient winds (unrelated to thunderstorms) tonight. A wind warning is in effect statewide and a high wind warning has been issued for Mobile, Baldwin and Washington counties. Expect intermittent wind gusts up to 40 mph, which could down some trees due to wet ground conditions. Those along the ridges could see a gust of up to 80 km/h in places. Tonight it will be very windy and noisy.

HEAVY THUNDERSTORM: Thunderstorms in southwest Alabama could produce hail, damaging winds and some tornadoes tonight. A strong tornado (EF-2 or higher) cannot be ruled out. The air over the northern half of the state will be cool and stable, and very little thunder is expected there. Slope winds are the problem over northern and central Alabama.

TIMED COORDINATION: High gradient winds are likely over the state from about 8 tonight through Wednesday morning. Gusts are still possible up to 25-30mph on Wednesday afternoon before tapering off on Wednesday evening. Regarding severe thunderstorms in southwest Alabama, the window is from tonight 11 a.m. through 4 a.m. Wednesday.

A NOAA weather radio is the baseline, and make sure you have wireless emergency alerts enabled on your phone. If you live in an RV, know the location of the nearest emergency shelter or 24-hour convenience store that can serve as a safe haven. have transportation available.

Due to strong wind gusts expected tonight, all states should secure loose items on your property.
