   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 75 CONTINUES. AN
   ENHANCED THREAT FOR DAMAGING WINDS MAY BE DEVELOPING AS BOW ECHO
   EVOLVES FROM DUNN/PEPIN COUNTIES.
   
   BROKEN LINE OF SUPERCELLS HAS BEGUN TO TRANSITION INTO A BOW ECHO
   TYPE STRUCTURE AROUND 20 W EAU. LATEST SURFACE ANALYSES INDICATE A
   DRY PUNCH HAS SWUNG NEWD AHEAD OF THIS LINE FROM CNTRL IA INTO EAU.
   DEW POINT DEPRESSIONS AROUND 30 DEGREES /INDICATIVE OF STEEP
   LOW-LEVEL LAPSE RATES/ WILL SUPPORT ENHANCED DOWNDRAFT POTENTIAL
   AMIDST 40 KT SWLY FLOW AT 1 KM PER SLATER IA AND BLUE RIVER WI
   PROFILERS. THIS SHOULD LEAD TO A GREATER THREAT FROM DAMAGING WINDS
   IN W-CNTRL WI OVER THE NEXT FEW HOURS.
