   AREAS AFFECTED...E-CNTRL MN
   
   CONCERNING...TORNADO WATCH 271...
   
   VALID 110145Z - 110315Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 271 CONTINUES.
   
   STORMS WILL CONTINUE TO POSE A SEVERE THREAT FOR AT LEAST ANOTHER
   HOUR OR TWO AS THEY TRACK NEWD INTO FAR E-CNTRL MN. WHILE LARGE HAIL
   HAS BEEN THE MAIN CONCERN AND WILL CONTINUE TO BE...A BRIEF TORNADO
   WILL ALSO BE POSSIBLE AS THE STORMS INTERACT WITH WARM FRONTAL
   BOUNDARY.
   
   FURTHER N AND E...SFC DEWPOINTS DIMINISH GREATLY FROM THE UPPER 60S
   ENVIRONMENT WHERE STORMS ARE CURRENTLY LOCATED TO THE UPPER 40S AND
   50S. COMBINED WITH LOSS OF DAYTIME HEATING...EXPECT THAT STORMS WILL
   EVENTUALLY BEGIN A RAPID DECREASE IN INTENSITY WITH CONTINUED NEWD
   TRACK INTO LESS FAVORABLE ENVIRONMENT.
