Episode Narrative

A line of thunderstorms moved across Central Alabama during the early morning hours of Wednesday, February 7, 2018. Supercells embedded within the line were responsible for producing large hail, damaging winds, and several tornadoes. Severe weather was not anticipated as most model guidance indicated insufficient instability and wind shear for the development of supercells, tornadoes and other severe convective hazards. Even so, a marginal risk was highlighted for the western and southern portions of Central Alabama. The storms exhibited organization and frequent lightning, indicators that instability was likely higher than expected. The radar signatures were marginal at best and therefore, only a few Severe Thunderstorm Warnings were issued during the event.
