Severe weather analysis – 242 pm

It’s still clear where the front is from the strong temperature and dewpoint gradient in the analysis above…now from near Selma to Montevallo to Weiss Lake.  Research has shown that on the near and just south of a front like this, atmospheric shear is enhanced.  This explains the tornado warnings and rotating storms generally concentrated from south of Tuscaloosa earlier to Alex City area now.  Given the location of the front, expect the tornado threat to stay south of I-59 for the most part, so people in BHM, TCL, Cullman, and Huntsville are in the clear.

South of the front, in places like Anniston, Springville, Alexander City, Jacksonville, and Montgomery, the threat for damaging winds and tornadoes will continue.  However, the threat is not nearly what it was during the major outbreaks in the spring.  That day, energy-helicity index was near 10, today it is  only 1, and that is south of the front.
