   MESOSCALE DISCUSSION 1036
   NWS STORM PREDICTION CENTER NORMAN OK
   0632 AM CDT TUE JUN 17 2014

   AREAS AFFECTED...W-CNTRL LOWER MI

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 171132Z - 171300Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...LOCALIZED STRONG WIND GUSTS MAY OCCUR WITH A CLUSTER OF
   RAPIDLY PROGRESSING STORMS FROM CNTRL LK MI.

   DISCUSSION...LONG-LIVED STORM CLUSTER THAT HAD EVOLVED INTO AN MCV
   OVER THE MS VALLEY WEAKENED SUBSTANTIALLY ACROSS FAR SE WI DURING
   THE PAST HOUR...WITH COMMA-HEAD STRUCTURE BECOMING ILL-DEFINED.
   FURTHER WEAKENING OF THIS CLUSTER APPEARS PROBABLE OVER THE
   COOLER/MORE STABLE LK MI AIR MASS. DOWNSTREAM AIR MASS OVER W-CNTRL
   LK MI HAS LIKELY BEEN STABILIZED TO SOME EXTENT IN THE WAKE OF A NOW
   DECAYING MCS APPROACHING LK HURON. NEVERTHELESS...WITH 45 KT SWLYS
   AT 1 KM AGL SAMPLED IN GRR/APX VWP DATA...AND CLUSTER MOVEMENT STILL
   AROUND 60 KT...IT IS POSSIBLE THAT LOCALIZED STRONG WIND GUSTS COULD
   MIX TO THE SURFACE WITH A RISK FOR DAMAGING WINDS.
