UPDATE: System May Be Shifting North
Our latest model runs are suggesting that this winter storm system could be shifting further north. That means Sioux Falls could get more snow and an increased likelihood of blizzard conditions in the Sioux Falls area tomorrow into tomorrow night. As of right now, I am forecasting a range of 2 to 5 inches across the Sioux Falls metro area, however, if the midday model run remains consistent with our latest run and continues to suggest that this storm system will track further north, I will most likely adjust that snow forecast range upward by several inches.
Stay tuned for updates… I should have new information by around noon or shortly after.
Previous Update Below
A powerful winter storm system is winding up and getting ready to move into our area late tonight and will bring heavy snow and strong wind gusts to the Tri-State region through Tuesday night and into early Wednesday.
A Blizzard Warning is in effect from 3 AM tomorrow through 4 AM Wednesday for Union County, SD and parts of northwestern Iowa including the Okoboji area, Orange City, Sioux Center, Sioux City, and Elk Point. A Blizzard Watch is in effect from late tonight through Tuesday night for extreme southeastern South Dakota, a large portion of northern and western Iowa, southern Minnesota, and eastern Nebraska. South Sioux Falls, Harrisburg and Tea (Lincoln County) are included in the Blizzard Watch. I 90 from the Minnesota line east across Minnesota is included and I 29 from Sioux Falls south past Omaha is also included in the Blizzard Watch.
Snow will develop from southwest to northeast late tonight and continue through much of the day tomorrow. Snowfall accumulation will range from between 2 to 5 inches across the Sioux Falls Metro area to over 12 inches southeast of Sioux City and Spencer, Iowa. Strong north wind gusts from 25 to 35 mph will create blowing snow through much of the day tomorrow and into tomorrow night. Blowing snow will reduce visibility to near zero at times making travel nearly impossible at times.
We are going to be keeping a very close watch on this developing storm. Stay with us for the very latest updates.

We are tracking another powerful winter storm system today. A Winter Storm Warning is in effect for Clay and Union counties in South Dakota, eastern Nebraska, southern Minnesota and all of Iowa. A Winter Weather Advisory will go into effect this afternoon for a good chunk of eastern South Dakota including Sioux Falls, Yankton, Mitchell, Huron, Miller, Redfield, Brookings, Watertown and Sisseton.
Snow will begin by late this morning or early this afternoon and continue through tonight. Travel conditions will deteriorate quickly as the storm moves in during the day today. Total snowfall accumulation of 4 to 8 inches is likely with the heavier amounts east of Sioux Falls and lighter amounts north and west of Sioux Falls. The wind will kick in for a while this afternoon through tonight creating areas of blowing snow that will reduce visibility significantly at times. While the heaviest snow will fall later today through tonight, light snow will continue through Tuesday and into Tuesday night with, perhaps, an additional one-half inch to an inch of accumulation possible.
The storm will have an even bigger impact to our east. Parts of central and eastern Iowa, south central and southeastern Minnesota and western Wisconsin could get 8 to 12 inches or more of accumulation by tomorrow.
A Winter Storm Warning is in effect all along I-90 from the SD/MN line to Chicago and along I-29 from Beresford, SD to Kansas City and beyond. Some flights from the Sioux Falls regional airport have already been delayed or canceled.

It’s Monday morning and we’re gonna hit the ground running in the ‘ol weather department this week. This morning it’s cloudy and dreary with areas of freezing drizzle in places. Plus, we are watching a winter storm system that will impact much of our region late tonight, tomorrow and Wednesday. In fact, a Winter Storm Watch has already been issued for much of western, central and northern South Dakota.
I’ll start with today: Today will be cloudy, foggy and drizzly. With temperatures hovering around the freezing mark this morning – especially across central and northern South Dakota – roads are icy in places. Be prepared to give yourself plenty of time to get to work, school or wherever you might be headed this morning. In the Sioux Falls area, temperatures are in the mid 30s and should stay there most of the day, however, there could also be slick spots around the Sioux Falls area throughout the day.
Meanwhile, a powerful winter storm system is gearing up in the Colorado Rockies. This system will move across our area late tonight, tomorrow and Wednesday. A Winter Storm Watch is already in effect for much of western, central and northern South Dakota. Areas of freezing drizzle will develop late tonight and will be followed by heavy snow tomorrow into Wednesday. As of right now, I think the heaviest snow will fall across western, central and northern South Dakota where some locations could get 6 or more inches. In Sioux Falls, freezing drizzle will be followed by snow – possibly 2 or more inches. By Wednesday, strong northwesterly wind gusts to 40 or more mph will create blowing snow that will reduce visibility at times.
In addition to the snow and wind, temperatures will continue to drop through the week. Highs will only reach the upper 20s to low 30s on Tuesday and Wednesday, falling into the teens by Friday. The weekend ahead will be dry but cold. Highs will only reach the upper 20s on Saturday but will warm into the 30s on Sunday.

A powerful winter storm system will bring a significant, long-duration snowfall event to much of South Dakota, Minnesota, Iowa and Nebraska today and tomorrow. With 6 to 10 or more inches of snow likely over the next couple of days and wind gusts to 20 or 25 mph tomorrow into tomorrow night, travel will be impacted. A Winter Storm Warning is in effect for much of our region – including the Sioux Falls metro area – through Tuesday evening.
The storm will begin with areas of light freezing drizzle this morning. That will quickly change to snow that will become heavy at times by later this morning and will continue through the afternoon. Our heaviest snow will fall during the day today with 4 to 6 inches possible today alone. Snow that falls today will be relatively wet and heavy but will become lighter and fluffier as temperatures drop slightly this afternoon. Snow, while a bight lighter, will continue to fall through tonight and tomorrow with an additional 2 to 4 inches possible through tomorrow evening.
The wind will be relatively light both today and tonight, however, it will increase tomorrow. Gusts to 25 mph are possible by tomorrow afternoon through tomorrow evening and that will create areas of blowing snow at times, especially in rural areas.

Roads are icy but passable. Just take it easy and allow plenty of extra time for travel.
