CEDAR RAPIDS, Iowa (KCRG) – After sunshine this afternoon cloudiness will redevelop again tonight. Fog is a part of this redevelopment. In spots of eastern Iowa, particularly in the northeast zone, some of the fog could be dense overnight through the morning commute. Visibility could be lower than one-quarter of a mile at times. Give yourself some extra time and turn on your low beams. A strong storm system takes shape in the Plains Friday through this weekend.
