DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0231 AM CDT THU APR 12 2007
VALID 141200Z - 151200Z
..THERE IS A SLGT RISK OF SVR TSTMS ACROSS MUCH OF THE DEEP S INTO
THE SERN STATES...
..DEEP SOUTH INTO THE SERN STATES...
STRONG UPR LOW THAT WILL MOVE INTO THE SRN PLAINS AREA ON FRI WILL
DEAMPLIFY FOR A TIME SATURDAY AS IT PHASES WITH THE NRN STREAM. NRN
STREAM ENERGY DIGGING SWD ALONG THE LONGWAVE TROUGH AXIS LATER
SATURDAY WILL ENHANCE THE UPR LEVEL JET ACROSS THE CNTRL/ERN GULF
COASTAL AREA.
WIDESPREAD TSTMS...SOME SVR...WILL LIKELY BE ONGOING ACROSS THE
MID-SOUTH AND WRN GULF COAST REGION EARLY SATURDAY. THE WARM SECTOR
AHEAD OF THE STORMS WILL CONTINUE TO MODIFY THROUGH THE DAY
SATURDAY...WITH 60S DEW POINTS ADVECTING NWD INTO ERN LA...SRN PARTS
OF AL/MS AND THE WRN FL PNHDL. THIS SHOULD RESULT IN SUFFICIENT
DESTABILIZATION FOR TSTM INTENSIFICATION...EITHER FROM MORNING
ACTIVITY...OR FROM NEW DEVELOPMENT ALONG BOUNDARIES ACROSS THE DEEP
SOUTH.
SUFFICIENT SHEAR WILL EXIST FOR SUPERCELLS...THOUGH THE SOMEWHAT
UNIDIRECTIONAL CHARACTER TO THE EXPECTED PROFILE WOULD SUGGEST
LINES/BOWS WITH POSSIBLE HIGH WINDS...HAIL AND ISOLD TORNADOES. AS
THE TROUGH INTENSIFIES AGAIN DURING THE EVE...THERE MIGHT BE A
SLIGHTLY HIGHER POTENTIAL FOR MORE DISCRETE CELLS FARTHER DOWNSTREAM
ACROSS SRN AL...SRN GA AND NRN FL. ACTIVITY IS EXPECTED TO
MOVE/DEVELOP ENEWD TOWARD THE ERN CAROLINAS BY 12Z SUNDAY AS THE LLJ
AXIS SHIFTS QUICKLY ENEWD TO NEAR THE SERN COAST.
