Patchy fog or very light freezing drizzle may redevelop across eastern portions of central Iowa tonight. This could lead to some slick spots on roads due to freezing fog deposits or the patchy freezing drizzle. Little or no ice accumulation is anticipated. Quiet and cold conditions are then expected into Saturday with highs only around 10 above north and into the 20s south. Another weather system may impact Iowa late Sunday into Monday bringing a chance for some accumulating snow to southern Iowa. For the latest forecast, visit weather.gov/desmoines
Another weather system will impact Iowa beginning late Sunday afternoon across southern Iowa and continue into Iowa Sunday night and Monday before exiting the state late Monday afternoon. Temperatures will be cold enough for the precipitation to be all snow with this system, with some potential for accumulating snow across southern Iowa. Just how far north the accumulating snow will reach is still in question, with a possibility that this system will track further south across Missouri and limit the accumulating snow potential across Iowa. The Monday morning commute is likely to be impacted by the snow. The latest updated forecast can be found at weather.gov/desmoines.
