DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0346 AM CST FRI MAR 12 2010
VALID 151200Z - 201200Z
...SEVERE POTENTIAL TOO LOW TO DELINEATE A SVR RISK AREA...
VARIABILITY AMONG THE MEDIUM RANGE FORECAST GUIDANCE BECOMES
CONSIDERABLE BY THE END OF THIS FORECAST PERIOD. BUT MODELS ARE
SUGGESTIVE THAT A SIGNIFICANT NEW UPPER CLOSED LOW OR TROUGH WILL
EVOLVE ACROSS THE SOUTHEASTERN U.S. DURING THE EARLY TO MIDDLE PART
OF NEXT WEEK...AS A PRECEDING LARGE CLOSED LOW FINALLY WEAKENS AND
ACCELERATES AWAY FROM THE ATLANTIC SEABOARD. RELATIVELY DRY/STABLE
CONDITIONS EXPECTED ACROSS MUCH OF THE NORTH CENTRAL AND
NORTHEASTERN GULF OF MEXICO BY EARLY NEXT WEEK ARE EXPECTED TO
PERSIST...WHILE LOW-LEVEL RIDGING NOSING SOUTHWARD FROM THE LEE OF
THE ROCKIES STABILIZES MUCH OF THE WESTERN GULF OF MEXICO.
