A cold front will move into the state from the northwest this afternoon and evening. Very warm air will push temperatures into the 80s over the southeast half of the state, with 70s over much of the rest of the state. The far northwest will only reach the 60s. Thunderstorms are expected to develop along the cold front late this afternoon and tonight. The front will stall across southeast Iowa on Wednesday with rain continuing through the next few days. Cold air spilling into the central U.S. will change the rain to snow over much of northwest and central Iowa Thursday and Thursday night. (NWS/Des Moines)
