AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
529 AM CDT FRI APR 21 2006

.DISCUSSION...
AFTER A FEW DAYS OF RATHER SIGNIFICANT HAIL PRODUCING
THUNDERSTORMS ...WE ARE POISED FOR ANOTHER ROUND OF SEVERE WEATHER
TODAY AND TONIGHT. THEN THINGS BEGIN TO QUIET DOWN FOR A FEW DAYS.

FAIRLY CONFIDENT A FEW STORMS IN THE PAST SEVERAL HOURS PRODUCED HAIL
UP TO THE SIZE OF GOLF BALLS...ACROSS WALKER, WINSTON, TUSCALOOSA,
AND FAYETTE COUNTIES...ALTHOUGH NO REPORTS OF THAT SIZE HAVE COME IN
JUST YET. STILL A FEW THUNDERSTORMS LURKING AROUND BUT THEY HAVE LOST
INTENSITY FOR THE TIME BEING.

COMPLEX WEATHER SCENARIO SETTING UP FOR THE NEXT 30 HOURS ACROSS
CENTRAL ALABAMA. NOW TO THE DETAILS...
1) STORMS ACROSS THE FORECAST AREA THIS MORNING HAVE DEVELOPED WITH
THE AIDE OF RESIDUAL BOUNDARIES AND INCREASED LOW LEVEL BOUNDARY
LAYER FLOW. EXPECT THESE STORMS TO CONTINUE TO WEAKEN EARLY THIS
MORNING...ALTHOUGH SMALL HAIL COULD STILL FALL IN A FEW SPOTS THROUGH
8 AM.

2) MCS ACROSS NORTH CENTRAL MISSISSIPPI FIRING UP WITH THE HELP
OF A SHORT WAVE TROUGH...SURFACE LOW ALONG COLD FRONT...AND MOISTURE
CONVERGENCE NEAR THE COLD FRONT AND PRE-FRONTAL TROUGH. ALSO EXPECT
THESE STORMS TO SHOW A WEAKENING TREND AS THEY APPROACH MARION AND
LAMAR COUNTIES BETWEEN 7 AND 9 AM. MID TO HIGH LEVEL BLOW OFF FROM
THESE STORMS SHOULD SLOW THE HEATING AND DESTABILIZATION IN
NORTHERN ALABAMA.

3) POTENT MID LEVEL SHORT WAVE TROUGH AND COLD FRONT STILL SCHEDULED
FOR ARRIVAL TONIGHT. A FEW SURFACE WAVES ALONG THE FRONT ARE ALSO
EXPECTED WHICH MAY ENHANCE STORMS IN THEIR VICINITY. THIS IS THE
TRICKY PART. CLOUDS AND SUBSIDENCE BEHIND UPPER DISTURBANCE THIS
MORNING WILL LIMIT DESTABILIZATION ACROSS NORTHERN ALABAMA
INITIALLY. WILL GO WITH THE IDEA THAT CONVECTION WILL FIRE LATE
THIS AFTERNOON ACROSS WESTERN ALABAMA AND SPREAD EASTWARD TO ALL
AREAS EXCEPT FAR SOUTHEAST THROUGH MIDNIGHT. THE MAIN SEVERE THREAT
WILL BE LARGE HAIL AND DAMAGING WINDS. AN ISOLATED TORNADO CAN
NOT BE RULED OUT ESPECIALLY LATE THIS AFTERNOON AND EARLY THIS
EVENING WEST OF INTERSTATE 65. STORMS THEN EXIT THE STATE EARLY
SATURDAY MORNING.

I WANT TO STRESS THAT THIS IS NOT A CLEAR CUT SCENARIO BY ANY
MEANS. THE POTENTIAL LIFTING MECHANISM TIMING AND DEGREE OF
DESTABILIZATION WILL PLAY A MAJOR ROLE IN THE DEVELOPING SITUATION.
PLEASE STAY TUNED TO ADDITIONAL WEATHER INFORMATION THROUGHOUT THE
DAY.

BLOCKY UPPER LEVEL PATTERN EVOLVING VERY SLOWLY FOR THE PAST SEVERAL
DAYS. LARGE UPPER CLOSED LOW SPINNING OVER THE WESTERN GREAT LAKES
AND SOUTHERN STREAM MIGRATING SEVERAL SHORT WAVE TROUGHS OVER THE
REGION. TWO STREAMS EXHIBIT SOME FORM OF INTERACTION OR PHASING THAT
WILL SEND AN UPPER TROUGH THROUGH CENTRAL ALABAMA BY SATURDAY
MORNING. THE GOOD THING WITH THIS TROUGH PASSAGE...WE ENTER NORTHWEST
FLOW ALOFT AND VIRTUALLY END THUNDERSTORM CHANCES AT LEAST FROM THE
SECOND HALF OF SATURDAY THROUGH MONDAY. THE NEXT FRONT ARRIVES IN THE
AREA ON TUESDAY WITH THUNDERSTORMS RE-ENTERING THE FORECAST. MODEL
GUIDANCE WAS CLOSE ON THE SYNOPTIC EVOLUTION BUT HAD MIXED RESULTS
IN THE MASS FIELDS. TAKE A MIX OF NAM/GFS IN THE SHORT TERM AND
GENERALLY ACCEPTED THE GFS IN THE EXTENDED.
