SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE BIRMINGHAM AL
330 PM CST MON MAR 9 1991

...SEVERE THUNDERSTORMS POSSIBLE OVER ALABAMA TONIGHT AND TUESDAY...
   ...FOLLOWED BY MUCH COLDER WEATHER TUESDAY NIGHT AND WEDNESDAY...

A DEVELOPING LOW PRESSURE SYSTEM OVER TEXAS AND OKLAHOMA IS EXPECTED
TO SPREAD RAIN AND THUNDERSTORMS ACROSS ALABAMA TONIGHT AND TUESDAY.
MOISTURE HAS BEEN INCREASING ACROSS ALABAMA THIS AFTERNOON. BUT
TONIGHT AND TUESDAY THE AIR OVER THE STATE IS EXPECTED TO BECOME
SUFFICIENTLY MOIST AND UNSTABLE SUCH THAT SOME THUNDERSTORMS COULD
POSSIBLY BECOME SEVERE.  AT 320 PM THIS AFTERNOON...SCATTERED STRONG
THUNDERSTORMS...SOME SEVERE...HAD ALREADY MOVED INTO NORTHWEST ALABAMA.

THUNDERSTORMS WILL INCREASE AS THE WEATHER SYSTEM BECOMES BETTER
ORGANIZED TONIGHT AND TUESDAY AND MOVES EASTWARD INTO ALABAMA.  SO
THE POSSIBILITY FOR SEVERE THUNDERSTORMS TO DEVELOP IS FORECAST IN
ALABAMA TONIGHT AND TUESDAY AND IN SOUTHEAST ALABAMA THROUGH TUESDAY
EVENING.

NATIONAL WEATHER SERVICE FORECASTERS WILL CONTINUE TO MONITOR THE
SITUATION VERY CLOSELY.  WE ADVISE THAT THAT YOU KEEP IN MIND THE
POSSIBILITY OF SEVERE WEATHER WHEN PLANNING YOUR ACTIVITIES
TONIGHT AND TUESDAY.

IN ADDITION TO THE THREAT OF SEVERE WEATHER...A TURN TO MUCH
COLDER WEATHER IS EXPECTED TUESDAY NIGHT AND WEDNESDAY. TEMPERATURES
WILL FALL INTO THE 20S IN NORTH ALABAMA AND THE 30S IN SOUTH ALABAMA
BY WEDNESDAY MORNING.  COLDER AIR WILL CONTINUE TO POUR INTO THE STATE
WEDNESDAY AND BY THURSDAY MORNING FREEZING TEMPERATURES...MOSTLY IN
THE 20S AND LOWER 30S...WILL OCCUR OVER MUCH OF ALABAMA.  IT IS
TOO SOON TO SAY...BUT IT APPEARS AT THIS TIME THAT ONLY THE COASTAL
SECTIONS MAY ESCAPE THE FREEZING TEMPERATURES.

DUE TO THE RELATIVELY MILD TEMPERATURES THE PAST FEW WEEKS...MANY
TREES AND SHRUBS ARE IN BLOOM OR HAVE DEVELOPED BUDS EARLY.
CONSEQUENTLY...PROTECTION OF MUCH OF THIS TENDER GROWTH IN THESE
PLANTS FROMF THE FREEZING TEMPERATURES IS RECOMMENDED.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR LOCAL RADIO OR TELEVISION
