URGENT - WINTER WEATHER MESSAGE
National Weather Service La Crosse WI
745 PM CST Thu Feb 23 2017

...Dangerous Winter Storm To Impact The Region Later Tonight
through Friday Night...Dangerous Travel Expected...

.A dangerous winter storm will impact the area tonight through
Friday night. This storm will contain strong winds, heavy snow,
rain, a wintry mix, and thunderstorms. Due to considerable snow
accumulations and strong wind, there will be significant impacts
to travel for most of the area. Blizzard Warnings continue for
portions of southeast Minnesota and northeast Iowa while Winter
Storm Warnings and Advisories continue for the rest of the area.

As of 730 PM, precipitation has moved northward, impacting areas
mainly along and south of Interstate 90. While mostly rain,
precipitation has already changed over to light snow across
portions of north central Iowa into southeast Minnesota. Snow,
rain, or a wintry mix will continue to lift northeastward this
evening. Minimal snow accumulation with limited impact to travel
is expected through midnight, although some slick spots may
develop on untreated roadways as temperatures begin to cool.

Travel will then become dangerous overnight through Friday as
snow becomes heavy coupled with strong northerly winds causing
blowing and drifting of the snow. Snow accumulations from 1 to 4
inches are expected overnight, highest north of a Charles City
Iowa, Winona Minnesota, and Black River Falls Wisconsin line. Some
thundersnow will also occur, adding to snowfall rates and reduced
visibilities. Light icing could also mainly south of I-90.

Plan on mostly snow continuing Friday through Friday night,
although a mix with rain or freezing precipitation could occur
near and south of Interstate 90 at times during the day Friday.
An additional 4 to 12 inches of snow is expected Friday through
Friday night with the highest amounts expected across southeast
Minnesota into west central Wisconsin.

Strong north winds with gusts 35 to 45 mph will cause significant
blowing and drifting of the snow Friday and Friday night which
will cause some whiteouts. This will be especially true in open
and unsheltered areas.

Expect any slush or standing water to freeze Friday night into
Saturday morning.

Prepare now for this dangerous winter storm, especially if you
have travel plans.
