The National Weather Service says a winter storm will move across Iowa on Wednesday spreading moderate to heavy snow over the state. The snow will intensify during the morning and persist into the afternoon before diminishing in the evening.

Heaviest snow will occur in a band from northwest to southeast Iowa where 5 to 7 inches are expected and a Winter Storm Warning is in effect. On either side of this heavy band, 2 to 5 inches will occur with lighter amounts in the far southwest and far northeast.

Much colder air will dive into the state behind the system with highs in the single digits on Thursday and readings well below zero by Friday morning
