Good evening. We’re watching a squall line move towards northwest Alabama at this 11 O’clock hour. The Storm Prediction Center may issue a severe thunderstorm watch over west and parts of central Alabama soon. Instability is pretty low, so I don’t expect widespread severe weather. An isolated damaging wind gust or isolated tornado is possible, mainly over west Alabama between now and 3am. After 3am, the line should be much weaker. Have a source to wake you up just incase a warning is issued for your area. We’ll be here watching it for you. If a tornado warning is issued for west Alabama, we’ll be on TV for the latest…
Here’s an udpate from the Storm Prediction Center.
DISCUSSION…LATEST RADAR IMAGERY SHOWS A BAND OF STORMS WITH EMBEDDED BOWS/LEWPS MARCHING EWD ACROSS NRN MS ATTM. THE DOWNSTREAM AIRMASS ACROSS AL INCLUDES A MUCH MORE STABLE BOUNDARY LAYER…SUGGESTING THAT SEVERE POTENTIAL SHOULD SLOWLY DIMINISH WITH TIME AS STORMS BECOME INCREASINGLY ELEVATED.
STILL…GIVEN THE WELL-ORGANIZED NATURE OF THE LINE — OWING TO THE VERY DYNAMIC MID-LEVEL SYSTEM…EXPECT SOME THREAT FOR LOCALLY DAMAGING GUSTS WILL LIKELY PERSIST FOR AT LEAST A COUPLE MORE HOURS. THUS…NEW WW MAY BE REQUIRED.
