SIOUX CITY, Iowa (KCAU) — A winter weather warning has been issued for multiple Siouxland counties.

Portions of east-central and southeast South Dakota, northeast Nebraska, and northwest Iowa have had the winter weather watches upgraded to warnings.

According to the National Weather Service, affected counties included in the new warning are Lyon, Osceola, Dickinson, Sioux, O’Brien, Clay, Plymouth, Cherokee, Emmet, Kossuth, Winnebago, Worth, Palo Alto, Hancock, Cerro Gordo, Pocahontas, Buena Vista counties in Iowa; Charles Mix, Douglas, Hutchinson, Bon Homme, Yankton, Minnehaha, Turner, Lincoln, and Union counties in South Dakota; and Boyd, Holt, Knox and Cedar counties in Nebraska.

The National Weather Service said that heavy snow is expected, with a total accumulation of 5-9 inches. The warning is in effect from Thursday midnight to Friday midnight.

They warn that blowing and drifting snow are expected with the snowfall, which would cause hazardous travel conditions, saying northeast winds will increase to 15 to 30 mph in the afternoon. They said that hazardous travel is expected to begin late Friday morning or early afternoon.

Those traveling are asked to monitor forecasts for updates.

If traveling through the snow, drivers are asked to have an extra flashlight, food, and water in your vehicle in case of an emergency. The latest road conditions can be found by calling 511.

(Dec. 8, 10:24 a.m.) – The first real snow of the season is approaching.

Since mid-November and through December, we’ve seen a lack of precipitation and cold seasonal temperatures. With temperatures back in the 30’s, our first appreciable snowfall is coming our way this Friday.

It’ll start off as a rain and snow mix as temperatures fall below freezing early Friday morning and transition to just snow as the day progresses. The best bet for widespread snow through Siouxland is during the daytime.

Accumulations are forecasted between 2-5 inches across the area. We’ll be focusing on the track of the system over the next few days, as shifts of a few miles in any direction can drastically alter the amount of snow a given area could receive.

The Sioux Falls area has remained as the highest accumulation expected with a chance to see over 5 inches of snow through the day. Temperatures over the weekend will be below or close to the freezing point, so this snow will be sticking around. A winter storm watch will be in effect for Friday.
