Some fog will be possible tonight. If the fog develops, there could be some patchy dense fog which may deposit some ice on roadways or sidewalks with temperatures below freezing. The fog may persist into Sunday morning. A slow moving storm system will exit the Rockies and lift east northeastward through the central US Sunday into Monday and into the Great Lakes toward mid week. This will allow for continued chances for snowfall across much of Iowa throughout the beginning of the work week. Initially this system will spread some light snow across mainly western Iowa Sunday night into Monday with general accumulations around an inch or less. As the system moves from MO into IL, additional snow will spread across much of central Iowa Monday night through Wednesday. This could bring some light accumulations to much of central Iowa, with moderate to heavy accumulations of snow possible across portions of south central and southeastern Iowa. Breezy conditions are also expected.
