   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 708
   CONTINUES.
   
   ISOLATED STRONG TO SEVERE STORMS REMAIN POSSIBLE MAINLY ACROSS
   CENTRAL MN THROUGH 17Z.  OVERALL DECREASING TREND IN COVERAGE OF
   STRONGER ACTIVITY IS EXPECTED TO CONTINUE THROUGH EARLY AFTERNOON
   AND THUS WILL LIMIT THE NEED FOR A NEW WW.
   
   SURFACE ANALYSES INDICATED A CONVECTIVE OUTFLOW BOUNDARY EXTENDED
   FROM THE TWIN CITIES METRO WSWWD TO JUST N OF RWF...NEAR ATY...TO 35
   SE MBG.  25-30 KT SWLY LLJ EXTENDING INTO ERN SD/WEST CENTRAL MN WAS
   MAINTAINING A WAA REGIME ALONG AND N OF THE OUTFLOW BOUNDARY AND
   SUPPORTING ADDITIONAL TSTM DEVELOPMENT WITHIN THE REMNANT MCS. 
   INFLOW OF STEEPER MIDLEVEL LAPSE RATES AND STRONGER INSTABILITY
   RESIDING OVER SD COMBINED WITH EFFECTIVE BULK SHEAR /40-50 KT/
   ACROSS CENTRAL MN SUGGEST THIS TSTM COMPLEX WILL CONTINUE TO HAVE
   NEW DEVELOPMENT INTO THE AFTERNOON.  HOWEVER...GIVEN DOWNSTREAM
   CLOUD AND PRECIPITATION SHIELD LIMITING SURFACE HEATING AND
   REDUCTION OF SBCINH...TSTM ACTIVITY IS EXPECTED TO REMAIN ELEVATED
   WITH PERIODIC STRONGER UPDRAFTS SUPPORTING AN ISOLATED SEVERE STORM.
