Bitter Cold Tonight into Thursday Morning

Weekend Accumulating Snow

Bitter cold conditions will settle over the state tonight into Thursday morning with record low temperatures possible in at least several Iowa cities. Wind chills as low as -15° to around -25° are forecast over central Iowa, which can cause frostbite on exposed skin in just 30 minutes. Ensure you are dressed in layers if you must be outdoors.

Accumulating snow is forecast to return to the region later Saturday into Sunday. Our current forecast has the highest snow chances - up to 50% - over northern Iowa, with a 30% snow chance for southern Iowa. This snowfall is expected to be a drier, fluffier snow. How much snow may fall, where the higher snowfall amounts will be, and will the wind on Sunday cause blowing snow are still things that are not certain. Please monitor the forecast as we refine details for this weekend's snowfall.
