MESOSCALE DISCUSSION 1150
   NWS STORM PREDICTION CENTER NORMAN OK
   0207 PM CDT THU JUN 14 2007
   
   AREAS AFFECTED...MUCH OF AL...FAR SRN MS
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 141907Z - 142000Z
   
   ISOLATED SVR TSTMS MAY DEVELOP OVER NRN/CENTRAL AL ALONG WEAK SFC
   TROUGH IN THE NEXT FEW HOURS. ADDITIONAL TSTMS...POSSIBLY SVR WILL
   MOVE OUT OF NRN GA/ERN TN INTO NRN AL IN THE NEXT FEW HOURS. FURTHER
   SOUTH...ISOLATED SVR THREAT IS POSSIBLE WITH SEA BREEZE TSTMS OVER
   FAR SRN AL/MS. 
   
   LATEST SFC ANALYSIS PLACES A SFC TROUGH FROM NWRN AL SEWD INTO
   CENTRAL AL. CONVERGENCE ALONG THIS BOUNDARY AND MINIMAL REMAINING
   CINH SUGGESTS THAT AT LEAST ISOLATED TSTMS ARE POSSIBLE ALONG THIS
   BOUNDARY BY 21Z.  TEMPERATURES IN THE LOWER 90S AND DWPTS NEAR 60 F
   WILL SUPPORT HIGHER BASED TSTMS. GIVEN BACKGROUND 20 KT NELY
   WIND...THERE WILL BE SOME POTENTIAL FOR ISOLATED DOWNBURST WINDS
   WITH ANY TSTMS THAT DEVELOP ALONG THIS BOUNDARY. ADDITIONALLY...
   TSTMS DEVELOPING OVER ERN TN/NRN GA WILL LIKELY MOVE INTO NRN AL IN
   THE NEXT FEW HOURS. IF THEY BEGIN TO ORGANIZE AND FORM A COLD
   POOL...A WW MAY BE NEEDED FOR NRN/CENTRAL AL BEFORE 21Z. 
   
   FURTHER SOUTH...TSTMS HAVE DEVELOPED OVER FAR SRN MS/SRN AL ALONG
   THE SEA BREEZE FRONT. THIS AREA REMAINS ON THE PERIPHERY OF THE
   BROAD NLY MID LEVEL FLOW. ENOUGH SHEAR WILL BE PRESENT TO SUPPORT
   WEAKLY ORGANIZED MULTICELL MODE. WITH MODEST INSTABILITY IN
   PLACE...THERE MAY EXIST AN ISOLATED SVR WIND THREAT WITH ANY OF
   THESE TSTMS.
