This Hazardous Weather Outlook is for northwest Iowa, west central
Iowa, northeast Nebraska, central South Dakota, east central South
Dakota, south central South Dakota and southeast South Dakota.

.DAY ONE...Today and tonight.

Gusty northwest winds will continue to decrease through this
morning. An area of light snow develops tonight with amounts around
an inch or less by daybreak Saturday.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

A major winter storm will impact the region Saturday evening into
early Monday. Strong winds and a risk of moderate to heavy snow will
impact some locations while a wintry mix south of the heaviest snow
could create light icing before the colder air and snow arrives.

The exact storm track and snowfall totals remain uncertain. However,
locations along/north of a line from Chamberlain to Beresford South
Dakota, to Ida Grove and Storm Lake Iowa, have a moderate (40-70%)
chance of seeing snow totals greater than 6 inches. Regardless of
amounts, north winds gusting 40 to 50 mph on Sunday may produce
blizzard conditions with significant travel impacts.

Continue to monitor forecasts closely and be prepared to adjust or
cancel travel plans.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected at this time.
