DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0351 AM CDT SUN MAR 08 2009
VALID 111200Z - 161200Z
...DISCUSSION...
AS THE EARLY WEEK UPPER TROUGH QUICKLY MOVES INTO EASTERN CANADA ON
DAY 4/WEDNESDAY...THE CENTRAL STATES COLD FRONT IS EXPECTED TO
CONTINUE A STEADY SOUTHWARD PROGRESSION...FOCUSING TSTM POTENTIAL
ACROSS PORTIONS OF THE LOWER MISSISSIPPI VALLEY AND TX. THE GENERAL
QUICK PROGRESSION OF THE FRONT/POTENTIAL FOR EXTENSIVE CONVECTION
AND AMORPHOUS LARGE SCALE FORCING SUGGESTS ANYTHING BEYOND AN
ISOLATED SEVERE THREAT IS UNLIKELY FOR DAY 4/WEDNESDAY.
THEREAFTER...IT SEEMS LIKELY THAT THE COLD FRONT/ASSOCIATED MOIST
PREFRONTAL AIRMASS WILL BE SHUNTED SOUTHWARD INTO THE NORTHERN GULF
OF MEXICO AS EXPANSIVE HIGH PRESSURE DOMINATES EAST OF THE ROCKIES
THROUGH LATE WEEK. AS SUCH...THE OVERALL SEVERE THREAT APPEARS QUITE
LOW INTO THE WEEKEND.
