...Blizzard Conditions Tonight Through Sunday North and West...
Heavy snow continues over western, northwestern and north central
Iowa at this time. Snowfall rates of two to three inches per hour
are very common. Increasing winds will lead to widespread blowing
and drifting snow with blizzard conditions along and north of an
Atlantic to Ames to Waverly line overnight tonight into Sunday.
Rain and a wintry mix is changing over to snow over portions of
central and east central Iowa.
The axis of heaviest snow is expected to fall from Denison and
Carroll north and east through Fort Dodge, Algona and Mason City
where eight to twelve inches may fall. One to three tiers of
counties either side of these areas confidence is lower due to a
sharp gradient in expected snowfall where amounts could
potentially vary one to four inches just across one county.
Regardless of how much snow falls, wind gusts of 35 to 50 mph
later tonight into Sunday will produce blizzard conditions where
more than several inches of snow has fallen. Blowing and drifting
snow will continue into Sunday even after the snowfall has ended.
Travel will be very difficult to dangerous for much of tonight as
well as Sunday.
