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.
