Areas of fog over portions of Iowa and southern Minnesota this morning are expected to expand westward this afternoon through tonight, persisting into Christmas Day. Areas of drizzle could also develop, mainly along and east of the I-29 corridor. As temperatures fall below freezing tonight, freezing drizzle could produce a light glaze of ice on untreated roads and sidewalks. Locations north of I-90 are currently more favored to see potential icing, though portions of the I-90 corridor could also see a brief period of freezing drizzle Christmas morning. If you have travel plans tonight into Christmas Day, please be sure to check the latest weather and road conditions before heading out.
