Weather Summary for Upper Mississippi River Valley
National Weather Service La Crosse WI
428 AM CST Sun Jan 21 2018

Mostly cloudy to cloudy skies were the rule across the Upper
Midwest during the late evening and overnight hours. Even so,
areas of fog develop across much of southern Minnesota, northern
Iowa and the south half of Wisconsin. It was another seasonably
mild night across the region, with early morning temperatures
mostly in the upper teens to mid 30s.

Another mild day is in store for the area, even as clouds thicken
and light rain spreads into the south half of the region. Some fog
will persist across the south half of the region much of the day.
Look for highs to range from the mid 30s across the northland to
the mid 40s across southern Iowa.

Attention then turns to a strong winter storm system that will
impact the area tonight through Monday. The heaviest snow will
fall from south-central Minnesota into northern Wisconsin, where
accumulations of 6 to 12 inches are likely, with much of this
falling Monday into Monday evening. Farther south and east, a
wintry mix is expected, with some light ice accumulations
possible. Finally, in eastern Iowa and southern Wisconsin, mainly
rain is expected.

Lows tonight will be in the 20s across the northland to the lower
40s in southern Iowa. Highs Monday will range from the 20s across
the northland to near 50 in southeast Iowa and northern Illinois.
