   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH

   GUSTS HAVE BEEN ASSOCIATED WITH THE MOST INTENSE STORMS SINCE MID
   AFTERNOON ACROSS NORTHWEST WI/WESTERN U.P. OF MI. ALTHOUGH
   POTENTIALLY VERY UNSTABLE...THE 00Z MINNEAPOLIS OBSERVED SOUNDING
   REFLECTED A COUPLE OF DEGREES C OF WARMING SINCE 18Z IN THE 650-800
   MB LAYER. WITH THE PRIMARY UPPER TROUGH WELL INTO CANADA...THIS
   WARMING IS LIKELY REFLECTIVE OF THE PROGRESSIVELY LESS FAVORABLE

   FOCUSED ACROSS NORTH CENTRAL/NORTHEAST WI INTO THE U.P. OF MI...WITH
