URGENT - WINTER WEATHER MESSAGE
National Weather Service La Crosse WI
1159 AM CST Thu Feb 23 2017

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

.A dangerous winter storm is taking aim on the area tonight
through Friday night. This storm will contain strong winds, heavy
snow, rain, possibly a wintry mix, and thunderstorms. All this 
will impact the region tonight through Friday night. Due to 
considerable snow accumulations and strong wind, there will be 
significant impacts to travel for most of the area. Blizzard 
warnings have been posted for portions of southeast Minnesota and
northeast Iowa while winter storm warnings and watches remain in 
effect for a good portion of the rest of the area.

Rain and some snow will move in this evening with minimal impact 
expected on travel or activities. Travel will then become dangerous
overnight through Friday with snow becoming 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 Austin and Winona Minnesota to Black River 
Falls Wisconsin line. Some thundersnow will also be likely, adding
to snowfall rates. Light icing could also occur if freezing 
precipitation develops.

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 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 30 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.

Confidence is high that this storm will produce significant
amounts of snow. However, even a small shift in the storm track
will have large impacts on what falls where, and how much. There
still could be some slight adjustments as to where the heavy snow
band sets up.

Be sure to keep up to date on the latest forecasts and prepare
now for this dangerous winter storm, especially if you have 
travel plans.

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.

* Light snow or a wintry mix this evening will transition to all
  snow overnight. Then expect blizzard conditions with heavy snow
  to develop around midnight, tapering off Friday night. 

* Winds gusting as high as 45 mph will cause whiteout conditions
  in blowing snow. Significant drifting of the snow is likely,
  especially on ridge tops and in open areas. Tree branches could
  fall as well.

* Total snow accumulations of 10 to 16 inches are expected. Snow
  rates up to 2 inches per hour at times are also possible in
  thundersnow. 

* Travel will be very difficult to impossible...including during

mix. Snow or a wintry mix will continue overnight into Friday for 
most areas. 2 to 4 inches of snow have already fallen across 
portions of southeast Minnesota with lesser amounts south and 
east. Many area roads have become snow covered and slick, 
resulting in numerous slide offs. In addition, northeast winds

...Dangerous Travel Continues Today...

.A dangerous winter storm will continue to impact the Upper
Midwest through tonight with a combination of snow, wind, rain,
and ice.

As of 7 AM, heavy snow has occurred across parts of north- 
central Iowa through southeast Minnesota and west central 
Wisconsin with snowfall totals of 6 to 12 inches so far. Snowfall
amounts have been much lighter to the south where more of the 
precipitation has occurred as rain or a wintry mix. While 
precipitation has become lighter early this morning, snowfall is 
expected to increase through the morning as the storm system 
continues to track northeastward. 

Dangerous travel will continue through today as periods of snow 
coupled with strong northerly winds causing blowing and drifting 
of the snow. Additional snowfall accumulations of 4 to 8 inches 
are possible through tonight from north central Iowa through 
southeast Minnesota and parts of western Wisconsin with 1 to 4 
inches farther to the south. Storm total snowfall within the 
heaviest snow band will exceed a foot. A wintry mix will remain 
possible, especially across parts of northeast Iowa into 
southwestern Wisconsin before transitioning to snow later today or
this evening. Light ice accumulations are possible. 

Strong north winds with gusts of 30 to 40 mph will cause

URGENT - WINTER WEATHER MESSAGE
National Weather Service La Crosse WI
1037 AM CST Fri Feb 24 2017

...Dangerous Travel Continues Today...

.A significant winter storm will continue to impact the region
through tonight with a combination of snow, freezing drizzle, and
wind. 

As of mid morning, heavy snow from the overnight hours had tapered
off to a mix of light rain, freezing drizzle, and snow across the
area. Snow totals of 6 to 12 inches were common along and either
side of a line from Charles City, Iowa to Rochester, Minnesota to
Eau Claire, Wisconsin, with amounts tapering to less than an inch
across southwest Wisconsin and portions of far northeast Iowa near
the Mississippi River. Where heavy snow occurred, some blowing and
drifting of snow was also noted, though conditions had improved by
10 am in many areas.

Through the afternoon and evening hours, some light snow is
expected to redevelop eastward across the area, but with mainly
light additional accumulation. With continued stronger winds, some
blowing and drifting snow remains possible over parts of southeast
Minnesota and northeast Iowa where blizzard conditions may be
found at times along with hazardous travel. Farther south and east
into western and southwestern Wisconsin, precipitation for today
will remain a mix of light rain and snow, mixed with freezing
drizzle at times but changing to light snow before ending tonight.
Additionally, expect any slush or standing water to freeze 
overnight as temperatures dip well below freezing.

...Periods of Snow Return into the Evening...

.After a break in accumulating snowfall for many areas today,
a period of light to moderate snow will return through the 
evening and nighttime hours, gradually tapering off from west to 
east after midnight.

will result in some blowing and drifting of snow, especially for
open areas west of the Mississippi River, though the threat for
blizzard conditions has ended.
