   AREAS AFFECTED...WRN INTO CNTRL WI
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 232226Z - 232330Z
   
   TRENDS ARE BEING MONITORED FOR THE POSSIBILITY OF AN INCREASING
   SEVERE THREAT THAT COULD REQUIRE A WW WITHIN THE NEXT HOUR OR TWO.
   
   SUSTAINED CONVECTION IS NOW UNDERWAY NEAR/SOUTH AND WEST OF EAU
   CLAIRE WI...LIKELY MOSTLY ASSOCIATED WITH LOW-LEVEL WARM ADVECTION
   ALONG A REMNANT OUTFLOW BOUNDARY GENERATED BY OVERNIGHT CONVECTION. 
   AN INCREASINGLY DIVERGENT UPPER FLOW FIELD IS PROBABLY CONTRIBUTING
   TO DEVELOPMENT...WHICH MAY CONTINUE TO GROW UPSCALE AND ORGANIZE
   DURING THE NEXT FEW HOURS.  THIS WILL BE AIDED BY LOW-LEVEL INFLOW
   OF HIGH MOISTURE CONTENT AIR POSSESSING LARGE CAPE...IN THE PRESENCE
   OF STRONG SHEAR BENEATH 35-40 KT NORTHWESTERLY 500 MB FLOW.  GIVEN
   DEEP LAYER WESTERLY MEAN FLOW FIELDS STRENGTHENING TO AROUND 30
   KTS...THIS MAY BE ACCOMPANIED BY AN INCREASING RISK FOR DAMAGING
   WIND GUSTS...IN ADDITION TO AT LEAST MARGINALLY SEVERE HAIL...ACROSS
   CENTRAL WISCONSIN BY 00-02Z.
