ACROSS NORTHERN WI AND THE WESTERN MI UPPER PENINSULA THIS
AFTERNOON. LOCALIZED SNOW RATES MAY REACH 1 IN/HR FOR A FEW HOURS

WATER VAPOR IMAGERY DEPICTS COMPACT SHORTWAVE TROUGH PROGRESSING
FROM THE EASTERN DAKOTAS INTO MN EARLY THIS AFTERNOON. RELATIVELY
CONCENTRATED AREA OF MODERATE/OCCASIONALLY HEAVY SNOW IS OCCURRING
ACROSS NORTHWEST WI AT THIS TIME...WITH THIS ACTIVITY LARGELY
ORIENTED WITH MODEST LOW TO MID LEVEL FRONTOGENETICAL FORCING AND
ASCENT AHEAD OF UPPER IMPULSE. SIMILAR TO ONGOING TRENDS...LATEST
