Weather Summary for Upper Mississippi River Valley
National Weather Service La Crosse WI
338 AM CDT Fri Apr 13 2018

A broad area of low pressure was centered over Kansas early this
morning. Clouds ahead of this system had spread across much of the
Upper Midwest. The deeper moisture ahead of it was also arriving,
with showers and even a few thunderstorms spreading across
southern Wisconsin to northern Iowa and southern Minnesota. Early
morning temperatures ranged from some 20s across northern
Minnesota to near 60 across far southern Iowa.

The low will move slowly east today and strengthen. Rain will
continue to overspread much of the region today, with some
thunderstorms across the south half. A few storms in central and
southern Iowa could be strong to severe this afternoon and
evening. Some snow is expected across parts of northern Minnesota
and far northern Wisconsin this afternoon. Highs today are going
to range from the 30s across the northland, to the lower 70s in
southern Iowa.

The low will move little tonight with cooler air spreading into
Minnesota and Wisconsin. Rain and some thunderstorms are expected
to continue across the south half of the region, while across
much of Minnesota into central and northern Wisconsin the
precipitation turns to wintry mix. Winter storm watches and
warnings are posted for these areas tonight. Lows tonight will
range from the 20s across the northland, to the lower 40s in
southern Iowa.

Looking ahead, a prolonged period of wintry weather is set to
impact the Upper Midwest through the weekend. Winter storm
watches or warnings continue for much of the area into Sunday.
