wintry weather moves across the Dakotas late Saturday night into

late Sat night and a wintry mix or freezing rain is possible to
start off the day on Sunday.  There is a better chance for ice

allow a change over to mostly rain for Sunday afternoon. Expect a
wet and cool Sunday afternoon.  As the system departs and temps once
again fall below zero, a wintry mix of freezing rain or snow is
possible again Monday morning.  Wet weather continues through the
day on Monday with a drier and warmer airmass arriving for mid-week,
with temps ranging from the upper 30s to low 40s Wednesday.  Chances
for some light snow increase again by the end of the week as temps
