Very impressive bow echo signature on radar now, from near the Jefferson/Tuscaloosa county line, into southern Tuscaloosa county. Likely winds over 50 mph will move into the southern parts of the BHM metro area soon. Also, at the northern end of the bow, there is a “comma head” echo, indicative of some rotation. Occasionally, tornadoes can spin up at the northern end of intense bow echoes, so be ready to go to a safe place in Jefferson and Shelby counties.
