Strong gusty winds with periods of light snow showers and blowing snow will cause a significant reduction in visibility. Drifting snow will continue as well, with all of these conditions making travel extremely dangerous in rural open areas.
Because of this, a winter weather advisory is now in effect until midnight tonight. Conditions will only marginally improve into the evening hours. Visibilities will continue to drop down in intermittent snow showers with strong gusty northwest winds. The combination of strong wind and falling snow will continue to produce blowing and drifting snow into the evening.
Northwest winds of 25 to 35-mph with gusts to 40-mph or more will like likely. Visibility will be reduced to below a mile at times, and spotty areas down to near zero in rural open areas.
Travel is not advised in some areas due to considerable blowing snow and restricted visibilities. Numerous accidents have been reported along interstate 35 between Ames and Clear Lake. Drifting snow will also cause slick icy roads and dangerous travel. Conditions may change rapidly, even across individual counties. Winds of this magnitude may also affect driving of low profile vehicles and loose light weight objects.
