   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 620
   CONTINUES.
   
   LINEAR MCS CONTINUES ESE AT 40-45 KTS AND IS EXTRAPOLATED TO BE
   ALONG A LINE FROM JUST EAST OF EAU CLAIRE WI SWWD TO WINONA MN AND
   CHARLES CITY IA BY 0530-06Z.  SYSTEM CONTAINS A WELL-DEVELOPED
   MESO-HIGH/COLD POOL AND COULD CONTINUE TO PRODUCE AT LEAST ISOLD
   DMGG WINDS INTO WRN WI AND NERN IA FOR THE NEXT FEW HOURS.  IT
   REMAINS UNCERTAIN ON HOW FAR E AND SE THE SVR THREAT WILL EXTEND. 
   BUT...GIVEN BOTH A VEERING/INCREASING WLY COMPONENT TO THE LLJ AND
   PROPENSITY FOR THE RUC FCST SOUNDINGS TO SHOW ONLY MODEST MLCINH
   DOWNSTREAM...EXPECT SOME SVR THREAT TO EXTEND BEYOND THE MS RVR VLY
   INTO SRN/CNTRL WI AFTER 07Z.
