   MESOSCALE DISCUSSION 1607
   NWS STORM PREDICTION CENTER NORMAN OK
   0259 AM CDT SUN AUG 24 2014

   AREAS AFFECTED...PARTS OF NRN/CNTRL MN

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 240759Z - 240930Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...STRONG WIND GUSTS PRODUCING ISOLATED DAMAGING WINDS WILL
   ACCOMPANY THE LEADING EDGE OF A BULGING LINE SEGMENT TRACKING NE
   ACROSS PARTS OF W-CNTRL TO N-CNTRL MN OVER THE NEXT COUPLE OF HOURS.

   DISCUSSION...THE LEADING SURGE OF CONVECTIVE OUTFLOW ATTENDANT TO A
   WAVY QLCS YIELDED A 53 KT GUST AT KBBB DURING THE PAST HOUR...WITH
   MORE RECENT GUSTS OF 44 KT AT KAXN AND 39 KT AT KGHW. RECENT FORWARD
   PROGRESSION OF 45-50 KT /CONSISTENT WITH 3-6 KM AGL SPEEDS SAMPLED
   IN THE PAST COUPLE HOURS WITH THE FSD VWP/ MAY CONTINUE TO SUPPORT A
   SWATH OF STRONG WIND GUSTS THAT WOULD BE CAPABLE OF PRODUCING
   ISOLATED DAMAGING WINDS. HOWEVER...THIS SURGE WILL MOVE INTO A
   PROGRESSIVELY LESS UNSTABLE AIR MASS ACROSS NRN MN WHERE SURFACE
   TEMPERATURES ARE LARGELY IN THE MIDDLE TO UPPER 60S. THIS SHOULD
   YIELD A DIMINISHING SEVERE RISK AFTER ABOUT 09-10Z.
