...Freezing Ice Tonight Followed By Potential Blizzard Conditions
Saturday Evening Into Sunday...
.We are looking at two separate wintry weather impact events
across portions of Iowa. The impact for tonight into Saturday
morning will be freezing ice potential. The location of the
greatest icing potential may shift slightly, so this advisory may
be more "dynamic" than most advisories typically are. Winds should
be light during this event, so impacts will be precipitation-
driven. A more potent system will impact Iowa Saturday evening
Into Sunday. As much colder air moves into Iowa Saturday evening,
precipitation will change over to all snow, potentially heavy at
times. A narrow band of heavy snow is expected to set up across
portions of western, central and northern Iowa with this system.
There may be tight gradient on the north and south sides of this
narrow band of snow. Strong and gusty northwest to west winds to
increase across the state Saturday night through Sunday. This will
cause areas of blowing snow and potentially near-blizzard
conditions especially in rural areas.

...WINTER STORM WATCH NOW IN EFFECT FROM SATURDAY AFTERNOON
THROUGH SUNDAY AFTERNOON...
* WHAT...Blizzard conditions possible. Total snow accumulations
of 3 to 5 inches and ice accumulations of a light glaze
possible. Winds could gust as high as 50 mph.
* WHERE...Northwestern to north-central Iowa.
* WHEN...From Saturday afternoon through Sunday afternoon.
* ADDITIONAL DETAILS...Plan on slippery road conditions. Areas
of blowing snow could significantly reduce visibility. Gusty
winds could bring down tree branches.
A Winter Storm Watch for blizzard conditions means there is a
potential for falling and/or blowing snow with strong winds and
extremely poor visibilities. This can lead to whiteout conditions
and make travel very dangerous.
