Severe Thunderstorm Warning 140, NWS Birmingham, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM, AL
308 PM CDT MON MAY 21 2001

THUNDERSTORMS SHOULD CONTINUE ALONG AN OUTFLOW BOUNDARY ACROSS
CENTRAL AL THIS AFTERNOON, AND SLOWLY DRIFT SOUTHWARD THROUGH THE
EVENING.  A SEVERE THUNDERSTORM WATCH WAS IN EFFECT THIS AFTERNOON
AND I WOULD NOT BE SURPRISED TO SEE IT EXTENDED FOR A TIME LATER IN
THE EVENING FOR AREAS SOUTH OF INTERSTATE 20. ADDITIONAL SHOWERS AND
THUNDERSTORMS SHOULD DEVELOP NEAR THE COLD FRONT THAT WILL BE MOVING
THROUGH LATER, HOWEVER, I EXPECT THE MAIN SEVERE THREAT TO BE WITH
THE BOUNDARY CENTRAL AND SOUTH AL. I WILL CONTINUE WITH CATEGORICAL
POPS EVERYWHERE TONIGHT. THERE MAY BE SOME LINGERING PRECIPITATION
CENTRAL AND SOUTH EARLY IN THE MORNING, THEN MUCH COOLER AND DRIER
AIR WILL FILTER IN.
