Pulse thunderstorms continue to be widely scattered across the eastern half of North and Central Alabama this evening.
We say they are pulse storms because they form quickly, pulse up in intensity, then quickly rain themselves out, their updrafts choking on their own precipitation.
They are producing brief very heavy rain and intense lightning.
At 6:30 p.m., the severe thunderstorm warning for Chilton County has expired. The warning has been replaced by a significant weather alert for Chilton, Dallas and Perry Counties.
Storms continue over Chilton into eastern Perry County. They have “gusted out,” meaning that theyir cores have collapsed, spread strong gusty winds outward. These winds fan out in the of mini-cool fronts that are pushing north and northwest into Bibb and southern Shelby Counties. The boundaries can trigger new storms. This was happening to the east southeast of Calera.
Storms are becoming a little more numerous from northern Jefferson County around Warrior through northern Blount around Snead up to Albertville. A storm was forming south of Garden City, moving north into Cullman County.
Sea breeze storms (yes I said sea breeze storms) are over West Central Georgia moving northwest towards Chambers and Randolph Counties. These storms have pushed all the way from the Atlantic Coast!
