The National Weather Service in Sioux Falls has posted a Winter Weather Advisory for portions of northwest Iowa. The advisory will remain in effect until 9:00am Sunday Morning. Light freezing drizzle is expected in northwest Iowa during the overnight hours. While the atmosphere remains above freezing, temperatures at the surface should dip below freezing.
The combination could lead to some glazing of area roadways and sidewalks, potentially affecting travel during the overnight and early morning hours. People living in the area under the freezing drizzle advisory should be cautious if venturing out tonight or early tomorrow morning. A light glaze of ice on roadways is often difficult or impossible to see.
