   MESOSCALE DISCUSSION 0603
   NWS STORM PREDICTION CENTER NORMAN OK
   0523 PM CDT WED MAY 14 2014

   AREAS AFFECTED...FAR EASTERN AL INTO WESTERN/NORTH-CENTRAL GA

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 142223Z - 150000Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...BRIEF/LIMITED TORNADO RISK MAY EXIST INTO THIS EVENING
   ACROSS PARTS OF EASTERN AL/WESTERN GA...WHILE ISOLATED SEVERE TSTM
   WIND GUSTS WILL BE POSSIBLE IN THE SHORT TERM ACROSS NORTH-CENTRAL
   GA IN AREAS INCLUDING THE I-75 CORRIDOR.

   DISCUSSION...SOME OF THE TSTMS PARTICULARLY ACROSS FAR SOUTHEAST AL
   NEAR THE SOUTHWEST GA BORDER HAVE SHOWN SIGNS OF TRANSIENT LOW-LEVEL
   ROTATION OVER THE PAST 1-2 HOURS. THIS APPEARS COINCIDENT WITH A
   CORRIDOR OF DIFFERENTIAL HEATING/WEAK WARM FRONT AND MOIST LOW-LEVEL
   CONFLUENCE...AND WHERE DEEP-LAYER/LOW-LEVEL SHEAR IS ADEQUATE FOR
   UPDRAFT ROTATION. NON-CONVECTIVELY INFLUENCED WSR-88D VWP DATA
   ACROSS THE REGION SUGGEST THAT 0-1 KM SRH MAY BE AS HIGH AS 100
   M2/S2...WITH RELATIVELY STRONG DEEP LAYER VIA SOUTH-SOUTHWESTERLY
   WINDS ABOVE 1 KM. IN CONCERT WITH THE WEAK WARM FRONTAL FEATURE AND
   A PROGGED INCREASE OF 1-2 KM AGL SOUTH-SOUTHWESTERLY WINDS THIS
   EVENING...THE BRIEF TORNADO THREAT COULD GRADUALLY DEVELOP
   NORTH-NORTHEASTWARD ACROSS ADDITIONAL PORTIONS OF FAR EASTERN AL AND
   WESTERN GA THROUGH EARLY EVENING. 

   FARTHER EAST...BOUTS OF WIND DAMAGE WILL BE POSSIBLE THROUGH 00-01Z
   INTO NORTH-CENTRAL GA AS A COLD POOL/OUTFLOW-INFLUENCED LINEAR BAND
   OF CONVECTION SURGES NORTH-NORTHWESTWARD ACROSS NORTH-CENTRAL GA
   INTO A RELATIVELY WARM ENVIRONMENT.
