   AREAS AFFECTED...SRN WI/FAR NRN IL
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 635...636...
   
   VALID 220713Z - 220815Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   635...636...CONTINUES.
   
   DAMAGING WIND THREAT EXPECTED TO PROGRESS EWD ACROSS SERN/SRN WI
   THROUGH 08-09Z...WITH APEX OF BOW /NOW LOCATED OVER DODGE COUNTY/
   MOVING OVER LM BY 08Z.
   
   REGIONAL RADARS INDICATED A WELL-ESTABLISHED BOW ECHO TRACKING ENEWD
   ACROSS SERN WI AT 45-50 KT.  DOWNSTREAM AIR MASS ALONG THE WRN SHORE
   OF LM IS SOMEWHAT COOLER.  HOWEVER...STRONG WLY REAR INFLOW JET /50+
   KT/ ATTENDANT WITH BOW AS INDICATED BY BLUE RIVER WIND PROFILER
   SUGGESTS POTENTIAL FOR DAMAGING WINDS TO POSE A THREAT INTO THE WI
   COUNTIES ALONG THE SHORE OF LM.
   
   FARTHER SW...DAMAGING WIND THREAT MAY BE MORE ISOLATED ALONG SRN
   EXTENT OF BOW ACROSS FAR SRN WI AND WITH SECOND LINE OF TSTMS NOW
   ENTERING FAR NWRN IL.  THIS ACTIVITY IS EXPECTED TO TRACK EWD WITHIN
   INSTABILITY AXIS EXTENDING E-W ACROSS FAR NRN IL INTO SRN LM. 
   LIMITED SEVERE THREAT AND SMALLER AREAL COVERAGE OF THIS THREAT WILL
   LIKELY PRECLUDE THE NEED FOR A NEW WW TO THE S OF WW 636.
