Due to the moderate to heavy snow that will arrive this afternoon and evening, several counties have been upgraded from a winter weather advisory to a winter storm warning.
Snow will overspread much of northern Iowa this afternoon and then settle slowly southward into central Iowa tonight and early Friday morning. Snowfall rates will be moderate to heavy at times. In addition, northerly winds will increase late tonight into early Friday morning with areas blowing and drifting snow expected, especially in rural, open areas.
Heavy snow is expected with total snow accumulations of 5 to 7 inches now expected in the winter storm warning area. Northerly winds will increase to 15 to 25 mph tonight and will create areas of blowing and drifting of snow. The greatest potential for this heavy and blowing snow includes portions of Central Iowa mainly along the Highway 20 and Highway 3 corridors from 3 PM this afternoon to 9 AM CST Friday.
