URGENT - WINTER WEATHER MESSAGE

National Weather Service Twin Cities/Chanhassen MN

244 AM CST Sat Feb 23 2019

...DANGEROUS WINTER STORM EXPECTED TONIGHT THROUGH SUNDAY...

.A Winter Weather Advisory continues through Saturday morning for

portions of west central Wisconsin through southeastern

Minnesota, specifically along and east of a line from Blue Earth

to Faribault in Minnesota, continuing to River Falls and Bloomer

in Wisconsin. Snowfall accumulations of up to around 2 inches

along with up to a tenth of an inch of ice accretion can be

expected through Saturday morning.

A stronger system is expected for Saturday night through Sunday

when accumulating snow plus blowing snow will impact travel,

including blizzard conditions for much of southern and western

Minnesota.

A Blizzard Warning is in effect Saturday evening through Sunday

afternoon for most locations in Minnesota and Wisconsin south of

I-94. This includes southern portions of the Twin Cities metro,

away from more suburban areas. Within the Blizzard Warning, snow

accumulations will range from 1 to 3 inches in the west near the

South Dakota border to 6 to 8 inches along Interstate 35 and east.

The snow is expected from late Saturday afternoon through the

early morning hours Sunday, followed by strong winds of 25 to 35

mph with gusts to near 50 mph for most of the day Sunday. This

could lead to whiteout conditions, making travel very difficult or

impossible in the open areas of western, central, and southern

Minnesota, and far western Wisconsin.

A Winter Storm Warning is in effect Saturday evening through

Sunday afternoon for St Croix, Barron, Rusk, Chippewa, and Eau

Claire counties. Within the Winter Storm Warning, snow

accumulations of 6 to 9 inches can be expected with localized

higher amounts possible. The snow is expected Saturday evening

through Sunday morning, followed by strong winds of 20 to 30 mph

with gusts to 40 mph for most of the day Sunday. This may produce

areas of blowing and drifting snow, making travel difficult for

portions of far southeastern Minnesota into west central

Wisconsin.

A Winter Storm Watch is in effect for the counties along I-94

for the potential of 1 to 4 inches of snow and very strong wind.

Winds could gust as high as 40 to 45 mph which could lead to very

low visibility and dangerous travel.

stay with your vehicle.
