   MESOSCALE CONVECTIVE VORTICITY CENTER THAT EVOLVED FROM THE FORWARD
   PROPAGATING MCS IS TRACKING ENEWD TOWARD THE THUMB REGION OF LWR MI.
    A FEW TSTMS CONTINUE TO DEVELOP VCNTY THIS FEATURE AND ARE
   ATTEMPTING TO BUILD NEWD INTO NRN LWR MI.  HIGHEST POTENTIAL FOR
   DAMAGING WINDS AND HAIL APPEARS TO BE ACROSS AREAS EAST OF
   INTERSTATE 75 AND SOUTH OF A OSCODA-HOUGHTON LAKE LINE.  
   
   FARTHER N...CLOUD CANOPY ALLOWED THE BOUNDARY LAYER TO COOL AND 18Z
   GAYLORD MI SOUNDING WAS NOT PARTICULARLY UNSTABLE.  CLOUDS MAY CLEAR
   SUFFICIENTLY FOR A LITTLE RECOVERY THIS EVENING.  MIDLEVEL SHORTWAVE
   TROUGH CONTINUES TO TRACK EWD ACROSS WI AND STEEPENING LAPSE
   RATES/ENHANCED VERTICAL SHEAR HAVE BEEN AIDING STRENGTHENING TSTMS
   UPSTREAM.  SO...DESPITE THE RECENT LULL IN ACTIVITY ALONG NRN
   PORTIONS OF THE WEATHER WATCH...THE THREATS FOR HAIL/DAMAGING WINDS
   MAY INCREASE SOMEWHAT IN A COUPLE OF HOURS AS THE WAVE MOVES ACROSS
   THE REGION.  AS A RESULT...WILL MAINTAIN NRN/ERN PORTIONS OF WEATHER
   WATCH 468.
