Day 4-8 Outlook
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.
