DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0328 AM CDT THU MAY 24 2012
VALID 271200Z - 011200Z
...DISCUSSION...
THERE IS INCREASING CONFIDENCE...BASED ON LATEST MODEL
GUIDANCE...THAT A STRONG SHORT-WAVE TROUGH WILL EJECT INTO THE HIGH
PLAINS EARLY IN THE DAY4 PERIOD...THEN INTO THE UPPER MS
VALLEY/GREAT LAKES DAY5. THIS FEATURE SHOULD ERODE THE WARM EML
ACROSS MUCH OF THE MIDWEST SUCH THAT STRONG/SEVERE THUNDERSTORMS ARE
EXPECTED TO DEVELOP ALONG ADVANCING COLD FRONT. BY LATE IN THE WEEK
BOUNDARY LAYER MOISTURE SHOULD BE SUBSTANTIALLY HIGHER THAN
CURRENTLY OBSERVED ACROSS THE PLAINS. SRN EXTENT OF ORGANIZED
SEVERE EACH OF THESE DAYS IS SOMEWHAT IN QUESTION BUT LIKELY LIMITED
BY HEIGHT FALLS THAT SHOULD EXTEND INTO KS/MO.
