Hail Possible Tonight in Northwest Alabama


SPC Day One hail Probability Map

The Storm Prediction Center has included Northwest Alabama for a slight risk of severe weather tonight, mainly for the possibility of hail. Areas in Alabama covered in the risk area are roughly north and west of a line from Tuscaloosa to Guntersville.

Here is an excerpt from this morning's SPC Outlook:

BUT COMBINATION OF INCREASING MOISTURE AVAILABILITY...FAIRLY STEEP MID LVL LAPSE RATES...AND 55-65 KT UNIDIRECTIONAL WLY FLOW IN THE 700-500 MB LAYER WILL SUPPORT STORM ORGANIZATION/ SUSTENANCE. SLIGHTLY ELEVATED ROTATING STRUCTURES AND BOWS WILL POSE A THREAT FOR SVR HAIL...AND...ESPECIALLY TOWARD 12Z...POSSIBLY DMGG WIND

On another note, thanks to the guys at the NSSTC Weather Blog for posting some of my pictures from last Wednesday's dryline wind event in North Alabama in thir blog. They have an excellent blog with very extensive coverage of weather for the Huntsville NWS Office coverage area.
