...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.
