Late Night Update, Storms Moving Out, Wintry Weather Continues North

Showers and thunderstorms continue moving through the eastern and southeastern counties of the state. These storms are moving out of the state at this time (see image), however some thunder and lightning have been detected with the deformation zone snow in the northern counties of the state. This will continue in an isolated fashion through the rest of the night.

Looking at the northern counties, snowfall amounts of 4-5″ have been reported in and around Sioux City with more snow to occur through the rest of the night. Still thinking the heaviest snow will be in our northwestern through north-central counties with the earlier map. There has been some freezing rain and sleet which may limit a little of the snow amounts that are forecast. This has led to some road hazards in the northern counties of the state as well. Most of the precipitation in our northern counties will transition to snow if it has not done so already by Midnight while the rain and storms over the eastern counties will move out of the state leaving mainly drizzle for most of the night before the tail end of the deformation zone sweeps in during the morning hours with a burst of some snow.

If you have to be out tonight, be aware of the very changeable road conditions with the ice and snow in our northern counties and the rain in the south. Stay tuned for later updates.
