   WW WILL LIKELY BE ISSUED SHORTLY.
   
   SMALL CONVECTIVE CLUSTER APPROACHING THE MINNEAPOLIS AREA APPEARS TO
   BE MAINTAINED BY ZONE OF ENHANCED LOW-LEVEL WARM ADVECTION AND
   DIVERGENT UPPER FLOW AHEAD OF A WEAK IMPULSE EMBEDDED WITHIN THE
   SUBTROPICAL STREAM.  ACTIVITY IS MOVING EAST NORTHEASTWARD ALONG OR
   JUST SOUTH OF SURFACE FRONTAL ZONE AT AROUND 45 KTS...AND WILL
   PROGRESS THROUGH AT LEAST NORTH/WESTERN PORTIONS OF THE GREATER
   MINNEAPOLIS AREA BY 08Z.  SERIES OF OUTFLOWS WHICH HAVE ALREADY
   ADVANCED THROUGH THE MINNEAPOLIS AREA...ASSOCIATED WITH STORMS NOW
   TO THE NORTH/EAST...APPEAR SHALLOW...AND NOT SIGNIFICANT ENOUGH TO
   PRECLUDE CONTINUING DAMAGING WIND POTENTIAL WITH APPROACHING STORMS.
    RISK FOR DAMAGING WINDS MAY CONTINUE THROUGH THE RICE LAKE /EAU
   CLAIRE AREAS OF NORTHWEST WISCONSIN BY 09/10Z...BEFORE STORMS
   ENCOUNTER COOLER MORE STABLE BOUNDARY LAYER.
