Northwest Iowa — Earlier today (Wednesday) the National Weather Service in Sioux Falls had issued a Winter Weather Advisory for Lyon and Sioux counties in the broadcast area, and a Winter Storm Watch for the O’Brien and Osceola County portions of the broadcast area. That changed a bit mid-afternoon today.

Around 3:00 pm, the National Weather Service issued a Winter Weather Advisory for all four counties here in extreme northwest Iowa, O’Brien, Osceola, Lyon and Sioux.

The Winer Weather Advisory will be in effect from midnight tonight to 6:00 pm tomorrow (Thursday). The advisory calls for snow and blowing snow, with northwest winds of 25 to 45 mph. According to the National Weather Service, slippery road conditions and greatly reduced visibilities may result in brief near whiteout conditions around the area.

Forecasters are calling for total snowfall for this storm to be somewhere between two and four inches. But National Weather Service Meteorologist Kerry Hanko says it doesn’t take a great deal of snowfall to reduce visibility in the forecast high winds.

With the high winds forecast for the period, expect wind chill indices to reach as low as -20 degrees.

Once the snow has ended, the bottom will drop out of the thermometer once again, with daytime highs through the remainder of the work week into the weekend reaching only the single digits either side of zero, with overnight wind chills reaching the 20’s below zero.
