DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0341 AM CDT WED MAR 12 2008

VALID 151200Z - 201200Z

..DISCUSSION...

ECMWF AND GFS ARE IN REASONABLE AGREEMENT WITH MID LEVEL SPEED MAX
EJECTING EWD ACROSS THE NRN GULF STATES AND OFF THE CAROLINA COAST
EARLY SUNDAY MORNING. DEEP SW-WLY FLOW SHOULD ALLOW FOR BOUNDARY
LAYER RECOVERY AND STEEPER LAPSE RATES TO SPREAD ACROSS
CONVECTIVE-FREE ZONE OF TX/LOWER MS VALLEY INTO THE ERN GULF
STATES/CAROLINAS...ENHANCING INSTABILITY WITHIN STRONGLY SHEARED
ENVIRONMENT. ORGANIZED SEVERE THUNDERSTORMS SHOULD SPREAD FROM WEST
TO EAST BEFORE ENDING WITH FRONTAL PASSAGE EARLY SUNDAY MORNING.

BEYOND DAY4 TOO MUCH UNCERTAINTY EXISTS WITH EVOLUTION OF WRN U.S.
TROUGH FOR A SEVERE OUTLOOK.
