AREAS AFFECTED...MN...IA...WRN WI...IA

CONCERNING...SEVERE THUNDERSTORM WATCH 535...536...

VALID 272037Z - 272200Z

RISK OF DAMAGING WIND GUSTS/LARGE HAIL CONTINUES ACROSS WWS 535 AND
536.  NEW WW MAY STILL BE NEEDED TO THE EAST...ACROSS
WISCONSIN/PARTS OF UPPER MICHIGAN.

EVOLUTION OF VIGOROUS CONVECTIVE CLUSTER IS ONGOING ACROSS NORTH
CENTRAL/NORTHEAST MINNESOTA...WITH INTENSE LEADING EDGE OF STORMS
JUST EAST OF SURFACE FRONT...FROM NEAR BRAINERD INTO AREAS EAST OF
INTERNATIONAL FALLS.  PROXIMITY OF THIS ACTIVITY TO 35-40 KT
SOUTHERLY LOW-LEVEL JET SHIFTING INTO ONTARIO WILL ENHANCE POTENTIAL
FOR DAMAGING WIND GUSTS AS ACTIVITY SPREADS WEST THROUGH NORTH OF
DULUTH INTO THE MINNESOTA ARROWHEAD NEXT FEW HOURS.

THOUGH ACTIVITY HAS BEEN FOCUSED NORTH/NORTHEAST OF WEAKENING
MID-LEVEL CIRCULATION...DESTABILIZATION AHEAD OF COLD FRONT SUPPORTS
CONTINUING SEVERE THREAT TO THE SOUTH/SOUTHWEST OF THIS FEATURE. 
BEST POTENTIAL STILL APPEARS TO BE IN ZONE OF ENHANCED LOW-LEVEL
WARM ADVECTION NOW SPREADING EAST OF OMAHA INTO THE DES MOINES AREA
THROUGH 22-23Z.  HOWEVER...INCREASING CONVECTION IS EVIDENT WEST OF
MINNEAPOLIS MN...WHERE AIR MASS IS MODIFYING IN WAKE OF EARLY BAND
OF STORMS.
