Storms, then cold...


Slight risk issued by the Storm Prediction Center

I do not want to overstate this, but there is a slight risk for severe weather overnight in Alabama. Fortunately this system is not as potent as the one that went through here on February 6 or February 17. Nevertheless, there is a risk for damaging winds. The time of greatest risk will be during rush hour in the early morning hours. Storms may enter West Alabama around 3 a.m. and exit Alabama to the east by noon. Here is an excerpt from the SPC outlook:
DESPITE THE LOSS OF DAYTIME HEATING ...LOW-LEVEL MOISTENING AND
FORCING ASSOCIATED WITH THE SURFACE FRONT SHOULD BE SUFFICIENT TO
MAINTAIN THUNDERSTORMS OVERNIGHT. THE SEVERE THREAT IS EXPECTED TO
EVOLVE TO A MORE DAMAGING WIND THREAT OVERNIGHT ACROSS PORTIONS OF
TN/MS/AL...AS A LINEAR CONVECTIVE SYSTEM EVOLVES ALONG THE COLD
FRONT.
The big story this week will probably be the bitter cold weather on Wednesday. The models have been showing a major shot of cold air in here for Wednesday for at least a week. I would not be surprised if the temperature does not make it out of the 30's in parts of North Alabama on Wednesday. Bundle up and stay warm!

Before I go, let me give you a "head's up" for another possible severe weather outbreak next Tuesday March 4. A lot can change between now and then, but this one certainly bears watching.
