...TWO MAJOR WINTER STORMS TONIGHT INTO FRI MORNING AND SAT NIGHT
INTO MON MORNING...

.The first winter moves through northern Wisconsin tonight into
Friday morning bringing snow to areas along and north of US Highway
10 in central Wisconsin with expected amounts rising rapidly north
of Wisconsin Highway 29. With wind gusts ramping up overnight to 45
to 50 mph by Friday morning, unsheltered areas will see blowing and
drifting snow leading to hazardous driving conditions. Light snow
and blowing snow are expected to linger through the morning before
winds begin decreasing Friday afternoon.

The second winter storm could approach historic levels as a large
band of 12 to 18 inches of snow falls across the region with
localized amounts up to 24 inches. The main uncertainty in the
forecast is exactly where this band sets up with the highest
confidence currently from southeast Minnesota to between I-90 and
Highway 29 in Wisconsin. There will be a relatively sharp gradient
in snow amounts on the southern side of the snow band over northeast
Iowa and southwest Wisconsin. In addition to the heavy snow, winds
increase Sunday afternoon into Monday morning, with gusts of 35 to
50 mph possible west of the Mississippi River. These winds could
lead to widespread blowing and drifting of snow and blizzard
conditions, especially west of the Mississippi River. Regardless of
exact snow amounts, expect widespread major travel impacts
regionwide with some roads possibly becoming impassable.

* WHAT...Blizzard conditions possible. Highest total snow
accumulations between 12 and 18 inches with localized amounts
approaching 24 inches possible. Lesser amounts of 6 to 12 inches
of snow possible outside of this band. Winds could gust as high as
50 mph. A glaze of ice is also possible if the storm trends
further north.

* WHERE...Portions of north central and northeast Iowa and southeast
Minnesota.

* WHEN...From Saturday evening through Monday afternoon.

* IMPACTS...Travel could be very difficult to impossible. Widespread
blowing snow could significantly reduce visibility. The hazardous
conditions could impact the Monday morning commute. Gusty winds
could bring down tree branches.

Information:
Prepare for possible blizzard conditions. Continue to monitor the
latest forecasts for updates on this situation.
