AREAS AFFECTED...WI

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 021335Z - 021530Z

ISOLATED DAMAGING WINDS AND HAIL WILL BE POSSIBLE AS A BOW ECHO
TRACKS SEWD ACROSS WI OVER THE NEXT FEW HOURS. A WW MAY BE NEEDED BY
MID TO LATE MORNING.

WATER VAPOR IMAGERY SHOWS A WELL-DEFINED VORTICITY MAX OVER NW MN
WHICH IS MOVING QUICKLY SEWD. STRONG PVA ASSOCIATED WITH THE
SHORTWAVE WILL CONTINUE TO SUPPORT AN MCS WITH A COLD POOL MOVING
SEWD ALONG A QUASI-STATIONARY FRONT ACROSS WRN WI. AS INSTABILITY
INCREASES IN CNTRL WI THIS MORNING...THE LINE SHOULD BECOME
SFC-BASED. THIS COMBINED WITH INCREASING LOW-LEVEL LAPSE RATES
SHOULD RESULT IN A WIND DAMAGE POTENTIAL AS THE BOW ECHO MOVES
ACROSS WRN AND CNTRL WI OVER THE NEXT FEW HOURS. IN ADDITION...HAIL
WILL BE POSSIBLE WITH THE STRONGER CELLS IN THE LINE.
