   MESOSCALE DISCUSSION 0226
   NWS STORM PREDICTION CENTER NORMAN OK
   1007 PM CST FRI MAR 02 2012
   
   AREAS AFFECTED...CNTRL AND E-CNTRL AL / W-CNTRL AND NWRN GA / SERN
   MS
   
   CONCERNING...TORNADO WATCH 63...
   
   VALID 030407Z - 030600Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 63 CONTINUES.
   
   GREATEST TORNADO POTENTIAL SEEMS TO BE FOCUSED ACROSS CNTRL AND
   E-CNTRL AL DURING THE NEXT 1-2 HRS BEFORE MOVING EWD INTO W-CNTRL
   AND NWRN GA AFTER 06Z.  A NEW TORNADO WATCH WILL BE ISSUED WITHIN
   THE HOUR FOR PORTIONS OF CNTRL-SRN AL AND SERN MS.
   
   RADAR IMAGERY SHOWS AN INTENSE AND LIKELY TORNADIC SUPERCELL
   EXHIBITING VELOCITIES SEEMINGLY CONDUCIVE FOR A STRONG TORNADO
   --STRADDLING CHILTON AND AUTAUGA COUNTIES IN ALABAMA-- WITH THIS
   STORM PROJECTED TO MOVE INTO E-CNTRL AL WITHIN A FAVORABLY
   MOIST/UNSTABLE LOW LEVEL AIRMASS.  KMXX VAD SHOWS 400-500 0-1 KM SRH
   WHICH WILL SUPPORT NOT ONLY SUSTAINING LOW LEVEL MESOCYCLONES BUT
   POSE THE RISK FOR MULTIPLE TORNADOES WITH ANY VIGOROUS SUPERCELL
   MOVING FROM CNTRL AL EWD INTO WRN GA.  ALTHOUGH CAPE HAS DECREASED
   IN PART DUE TO DIURNAL COOLING...A VERY MOIST BOUNDARY LAYER IN
   WHICH STORMS CAN ROOT THEMSELVES IN THE NEAR-SURFACE LAYER WILL POSE
   NOT ONLY A DMGG WIND/LARGE HAIL THREAT...BUT ALSO THE POSSIBILITY OF
   A FEW STRONG TORNADOES.  FARTHER W...A SQUALL LINE WITH EMBEDDED
   STRONGER UPDRAFTS MAY FOSTER A LOWER /ALBEIT NOT INSIGNIFICANT/
   TORNADO/DMGG WIND RISK FROM MESOCYCLONES/MESOVORTICIES AS THE LINE
   PROGRESSES EWD FROM E-CNTRL MS AND N-CNTRL AL INTO CNTRL AL AND NWRN
   GA.
