DUBUQUE, Iowa (AP) — A blast of winter in late spring is hitting northern and northeastern Iowa. A snowstorm that is pushing through the upper Midwest this weekend is also moving through parts of northern Iowa, dropping heavy snow in the area, including along Interstate 35 through Clear Lake and Mason City. The snow, paired with high winds, rain and fog in some places, have cut visibility and made driving in the area dangerous.

The National Weather Service has issued a winter storm warning for the area, including the cities of Dubuque, Maquoketa, and Waterloo, until 10 p.m. Saturday.
