DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0656 PM CST WED NOV 12 2008
VALID 130100Z - 131200Z
...NO SVR TSTM AREAS FORECAST...
...S TX...
MID-LVL WAVE OVER NRN MEXICO WAS BEGINNING TO TURN ENE AND WILL MOVE
ACROSS FAR S TX OVERNIGHT. PRIMARY BAND OF TSTMS WILL LIKELY REMAIN
WELL OFFSHORE INVOF A PRE-FRONTAL TROUGH/LOW WHERE STRONGER
INSTABILITY WILL RESIDE. HOWEVER...ANOTHER AREA OF CONVECTION WITH
EMBEDDED TSTMS WILL LIKELY EVOLVE OVER NERN MEXICO AND ADJACENT
PARTS OF FAR S TX WITH THE APPROACH OF THE IMPULSE LATER THIS
EVENING. LINGERING INSTABILITY COULD STILL SUPPORT A THREAT FOR
ISOLD LARGE HAIL AND/OR DMGG WINDS GIVEN THE FAVORABLE BUOYANCY AND
DEEP LAYER SHEAR NOTED ON THE BRO 00Z SOUNDING.
...TN VLY AND SE ATLC CSTL AREA...
LEAD SHORTWAVE TROUGH OVER THE MID-SOUTH IS EXPECTED TO TRANSLATE NE
INTO THE OH VLY TONIGHT. CONVECTION WAS INCREASING JUST DOWNSTREAM
OF THIS IMPULSE OVER THE TN VLY IN ASSOCIATION WITH MODEST DCVA AND
WEAK ELEVATED INSTABILITY. ISOLD LIGHTNING STRIKES WILL BE POSSIBLE
DOWNSTREAM INTO MIDDLE/ERN TN...THE COALFIELDS OF KY/VA AND PARTS OF
UPSTATE SC/NC LATER TONIGHT.
MEANWHILE...INFLUX OF SE ATLC LOW-LVL MOISTURE MAY RESULT IN
SUFFICIENT DESTABILIZATION FOR ISOLD TSTMS LATE IN THE PD ALONG THE
CSTL FRONT AS IT RETREATS TOWARD THE CAROLINAS.
