AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM, AL
950 PM CST WED MAR 29 2000

STATIONARY FRONTAL BOUNDARY EXTENDS ACROSS CENTRAL GA AND CENTRAL AL
TO A LOW OVER CENTRAL LA.  THUNDERSTORMS HAVE BEEN DEVELOPING  ALONG
THE BOUNDARY OVER CENTRAL AL.  THE LOW IS FORECAST TO TREK EAST TO
VICINITY OF SE MS BY MORNING. SPC IS CANCELLING THE WATCH TO OUR
SOUTH.  WE ARE NOT LOOKING FOR SURFACE BASED INSTABLILTY TO GET ANY
FURTHER NORTH THAN IT ALREADY IS SO THE SEVERE THREAT FOR OUR AREA IS
RATHER MINIMAL...THOUGH THERE IS SOME THREAT OF LOCALIZED HAIL AS
THUNDERSTORMS IN THE MID MS VALLEY MOVE IN LATER TONIGHT.

THE CONVECTION TO OUR WEST HAS NEVER REALLY GOT ORGANIZED A-ND IT
LOOKS LIKE IT WILL STAY SOMEWHAT SCATTERED SO WILL LOWER THE POPS FOR
TONIGHT...AT LEAST FROM BHM N... AND MAYBE A BIT FOR THURSDAY ALSO.

.BHM...NONE.
