A light mix of rain and flurries will be possible, mainly north of Highway 30 tonight into tomorrow. Snowfall accumulations are not expected. Roads should stay in good shape, but isolated slick spots will be possible.
Mild weather will dominate the first half of the forecast. On Monday, highs will be in the 50s over SW Iowa, with a quick drop off NE of Des Moines as a warm front just starts to arrive. On Tuesday, much of Central Iowa will be in the very mild air, but a strong cold front will slam through by mid-afternoon.
Temperatures will fall sharply behind the front, from the 40s and 50s on Tuesday, to the 20s and 30s on Wednesday and likely teens by Thursday.
