We continue to monitor a developing spring storm system that is currently over the Plains. Ahead of the storm strong southerly winds have warmed temperatures into the lower 80s today. Huntsville reached 80 degrees for the first time this spring. The last time Huntsville reached 80⁰ was on November 3rd, 2012. Temperatures will reach the lower 80s Wednesday afternoon after morning lows in the middle 60s.
Wednesday night a line of thunderstorms will be moving towards the Mississippi River. This line will be racing out ahead of the main cold front. The line will weaken during the overnight hours but once the cold front catches back up with the rain the line will reform and could become severe as it moves into the Tennessee Valley late Thursday morning.
The primary threat with will be the potential for damaging straight line winds 50-70mph. By Thursday afternoon the line will get stronger as it moves from west to east and there will be the potential for some quick spin up EF0-EF1 type tornadoes as the line gets east of I-65 and moves towards Madison, Jackson, DeKalb, Marshall and eastern Morgan counties.
Storm timeframe…(Shoals 8-11am…Huntsville Metro 11am-3pm…Marshall, Jackson, DeKalb Co. 3pm-6pm)
