Have you ever wondered what our forecast workstations look like? Tonight's your lucky night! Our operations area features multiple workstations like this one where we study observations, weather models, and develop the forecast. Some of our workstations have up to 6 screens!

Although temperatures are warming steadily toward 15-30°, this does not come with plentiful sunshine. 10:26 am satellite imagery shows mid and high level clouds streaming across the region this afternoon. Clouds are expected to decrease this evening, as temps slip into the 20s.

We know, we might be starting to sound like a broken record but folks - above normal temperatures are almost here! Downside will be the strong wind, leading to patchy blowing/drifting snow. But wind chills remain above zero!
Forecast for the next five days. Blustery to windy with highs in the 30s and lows in the teens and 20s. Dry weather with patchy blowing and drifting snow.

Cold for most today, but warmer temps are on the way! Blustery winds could lead to isolated blowing snow, so be aware if traveling. With temps falling below freezing at night this weekend, watch for slick spots of snow melt refreeze.

Who's ready to thaw out a tiny bit? With deep snow cover, we won't get extremely warm, but the next week looks to be above normal (28-31F) for temperatures.
Warmer temperatures are ahead, with a chart showing a high in the teens on Friday, warming into the 30s through the middle of next week.

Temperatures continue to fall this evening. Many locations may see below zero overnight lows. Temperatures may begin to warm by daybreak, but winds will be on the increase. This will lead to very cold wind chills Friday morning.
Dangerous wind chills are expected. Lowest values from -15 to -30 degrees, coldest in Southwest Minnesota and warmest near the Missouri River. Wind chill advisories remain in effect into Friday morning for eastern South Dakota, southwest Minnesota, and northwest Iowa. Stay safe, and stay warm.

A cold night is on tap for the region, and this cold weather will persist through Friday. Wind chill values may fall below -20 in many locations! Good news though. Warmer weather is ahead!
With the breezy conditions expected to return Thursday and Friday, wind chill values are expected to be in the -20 to -30 range for most of the Tri-State area. Use caution outdoors, pack a winter survival kit in your vehicle, and monitor your furnace for proper functionality.

The Groundhog saw his shadow this morning, so he predicts 6 more weeks of Winter. It seems reasonable to us at NWS Sioux Falls, with 17" snow depth, falling temps today, and a "warmer" weekend only reaching 30-35°. The NWS 3 Month outlook looks chilly for the Sioux Falls area.

Another good example of the near surface blowing/drifting snow issues that will be common across the area into the afternoon. Be prepared for changing conditions and keep your headlights on!

The winds have come up and the snow is blowing once again. Watch for areas of reduced visibility, especially where the snow is blowing off the top of some of the deeper cuts along the highways. Headlights on!

In addition to the chance for flurries this morning, gusty northerly winds will result in the potential for drifting of existing snow back across roadways. Be prepared for changing road conditions in open areas! (📸 via

After another day of cooler temps, mild conditions return by the weekend boosting highs back into the 30s. Unfortunately before that, colder temps and breezy conditions will promote some wind chill concerns as quiet conditions continues.
Weather Outlook for tonight through Sunday. As breezy conditions return Thursday, some wind chill concerns will follow Thursday night. Otherwise, more mild conditions return this weekend as highs bounce back to the 30s.
