Significant Winter Storm Likely Thursday

Heavy Snow and Strong Winds Possible

JANUARY 8, 2017 - Siouxland's weather is currently delightful, but a big change is coming later this week. 

Monday's highs have been in the 40s for many spots, and we'll be back in the 40s Tuesday and Wednesday.

A mighty cold front will slam into Siouxland Wednesday evening. This front will have plenty of moisture to work with.

The precipitation will begin Wednesday evening as a mix of rain, sleet, and snow, but will change over to all-snow by midnight Thursday.

Expect heavy snow Thursday morning, tapering off Thursday afternoon.

How much? It still is too early to pinpoint, but some parts of Siouxland are in line to see 4-8" of accumulation in a heavy band that sets up. Outside of the heavy band, 2-4" of accumulation will be common.

Another issue: It will be windy. Gusts of 30-40 mph will be seen Thursday, causing blowing and drifting snow. Whiteout conditions will be possible during this storm.

The details of this system are still being ironed out, and the forecast is likely to change somewhat. Those with travel plans should continue to closely monitor the latest forecast on siouxlandproud.com and KCAU 9 News.

One other item: Behind this next cold front, you can expect another round of Arctic air. Wind chills will be below zero Friday through Monday, with the coldest wind chills around -30.

We'll keep you updated!
