Good Tuesday evening! Here’s an update on the risk of strong to isolated severe storms Wednesday afternoon. Looking over our latest highres computer model data coming in tonight, everything is on track. I expect a mostly weak and broken line of showers and storms to race southeast across west & central Alabama during the afternoon hours on Wednesday.
The best wind shear for tornado formation will be well north of Alabama. The best uplift for more widespread and intense thunderstorms will be well north of Alabama. Instability here will be decent for an early March event. Basically, we’ll have just enough instability and uplift to kick off a very thin and broken line of showers and storms. The more intense storms along the thin line may produce a damaging wind gust or two as it passes across central Alabama, with a quick burst of heavy rain and brief intense lightning. An isolated storm or two may even produce small hail. The risk of a tornado in central Alabama appears really low, but we’ll carefully watch storms. This will be an incredibly fast hitting event, where the storm may begin and end in your area within 15 to 30 minutes.
The thin, broken line will impact areas near Hamilton, Vernon, Fayette, Jasper, Cullman and Reform between noon and 4pm. Areas along I-59 such as Livingston, Tuscaloosa, Birmingham and Gadsden will deal with the storms between 2pm and 6pm. Storms will exit our south and east Alabama counties by 7pm, impacting areas around Auburn and Montgomery to the south of our coverage area.
