DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0326 AM CDT SAT MAY 12 2012

VALID 151200Z - 201200Z

...DISCUSSION...
A QUIESCENT PATTERN FOR SEVERE POTENTIAL IN MID-MAY APPEARS LIKELY
TO PERSIST THROUGH THE PERIOD. A WEAK MID-LEVEL IMPULSE INVOF THE
TX/MEXICO BORDER AT 12Z/TUE SHOULD EVOLVE EWD MID-WEEK...BUT WITH
WEAK FLOW FIELDS AND OFFSHORE LOW-LEVEL WINDS OVER MUCH OF THE GULF
COAST. CONSENSUS OF GUIDANCE SUGGESTS A LARGE-SCALE UPPER-LEVEL
TROUGH SHOULD APPROACH THE WEST COAST LATE WEEK...BUT DAMPEN
THEREAFTER AS IT SHIFTS INLAND.
