4 to 5 inches of now has already fallen in Sioux Falls. Snow will decrease in intensity by later this morning, but wind will continue to create blowing and drifting snow through tonight. As of right now, I’m thinking we’ll get about 5 to 7 inches in Sioux Falls with locally heavier amounts. About 3-5 inches is possible in Aberdeen.
Snow reports as of 8:15AM:
|Sioux Falls @FSD Airport||4.8|
|Sioux Falls Downtown||4.2|
A significant winter storm system will continue to bring snow and blowing snow to the region throughout the day today and into tonight. A Winter Storm Warning remains in effect for much of South Dakota, North Dakota, and Minnesota through this evening.
5 to 7 inches of accumulation is expected in and around the Sioux Falls metro area with heavier 3 to 7 inch amounts north of I-90. Strong northwest wind gusts to 30, possibly 40 mph today and tonight will create blowing and drifting snow that could reduce visibility to near zero at times, especially in rural areas. In addition to blowing snow, the wind will create dangerously cold wind chill factor to near 30 below zero tonight.
Snow will stop falling this evening but the wind will continue to create blowing and drifting snow through much of the night. This is a dangerous storm. If you get stranded, do not leave your car. Stay with your vehicle and wait for someone to find you. Conditions will improve by later tonight and tomorrow.

This morning, areas of dense fog in Sioux Falls and across the tri-state area will reduce visibility to less than one-half mile and make roads very slippery. Give yourself plenty of extra time to get to your destination this morning.
A winter storm system will bring big changes to our weather over the next couple of days. Snow and blowing snow are likely today, tonight and tomorrow and will be followed by bitter, arctic cold temperatures. A Winter Storm Warning is in effect for northern South Dakota. A Winter Weather Advisory is in effect along and north of I-90. The Winter Weather Advisory does not include the city of Sioux Falls.
In Sioux Falls, areas of light freezing rain are possible this morning. The freezing rain will change to just rain as temperatures warm above freezing later this morning. Light rain showers are possible through early afternoon. Rain will change to snow this afternoon as temperatures drop back below freezing. Light snow will continue through tonight and into tomorrow. 2 to 5 inches of accumulation is expected in Sioux Falls and across the tri-state area with heavier amounts possible just north of Sioux Falls. Wind will be fairly light across the region today but will shift to the northwest and increase to 15-25 mph tonight. Gusts to 30 mph are likely from late tonight through tomorrow night, creating blowing snow at times especially in rural areas.
In Aberdeen, Watertown and Pierre: Snow has already developed across portions of central and northern South Dakota and will continue today, tonight and into tomorrow. Later this afternoon and tonight strong northwesterly wind gusts to 35 mph will create blowing and drifting snow reducing visibility significantly at times. 3-5 inches of accumulation is possible in Pierre and Watertown, 5-7 inches is possible in Aberdeen.

We have been talking about a potential autumn storm system for the past several days and now, more than ever, this storm system looks as though it absolutely will deliver. In Sioux Falls and across the tri-state area there is a significant severe weather threat today. Large hail, damaging straight-line wind gusts and tornadoes are possible this afternoon and this evening. Rain will continue tonight and into tomorrow with a total of 1 to 2 inches across eastern South Dakota, southwest Minnesota and northwest Iowa through Saturday night. Across central and western South Dakota, this system is developing into what will become a significant winter storm.
A Winter Storm Watch Is in effect for central South Dakota. A Blizzard Warning is in effect for today into tomorrow across the plains of western South Dakota and a Winter Storm Warning is in effect for the Black Hills. 3-7 inches of snow is possible along and west of the Missouri River with up to 15 inches of snow combined with 40 to 60 mph wind gusts across the western plains of South Dakota. In the Black Hills, 1-2 FEET of snow is expected.
East of the Missouri River, precipitation will be mostly in the form of rain. We could see a little snow mixed in with the rain along and west of the James River, but I do not expect much accumulation. Clouds, showers and thunderstorms are likely today, tonight and tomorrow. 1 to 2 inches of rain is possible by the time the storm system winds down on Saturday night. By Sunday, rain will end and the clouds will move out with sunshine and above-average highs returning for most of next week.

Check Back… I’ll be adding some pics and graphics later this morning.
We have one more mild day to enjoy before some BIG TIME changes take place as we head into the weekend. Today will be partly cloudy with clouds increasing and even a few scattered thundershowers developing this afternoon. High temperatures will range from the low 80s in Sioux Falls and across the tri-state area to the low 70s across central and northern South Dakota.
Clouds will increase this afternoon with showers and thunderstorms possible this evening and overnight tonight. Scattered showers and thunderstorms will continue, on and off, through the day tomorrow and into tomorrow night. I don’t expect a constant rain tonight and tomorrow, however there will be numerous scattered showers and thunderstorms. One-half inch or more of rain is possible in some places through tomorrow.
A low-pressure system will move out of the Rockies and onto the plains on Friday, bringing widespread rain for everyone and the possibility of severe weather across extreme southeast South Dakota, southern Minnesota and most of Iowa. On the backside of the low, rain and colder temperatures are likely. In fact, a couple of our forecast models hint at the possibility of snow mixing in with the rain along and west of the James River on Saturday. Stay tuned for updates on that. Whatever happens, I do not expect snow to be a big deal. Although, I know that the first snowflakes of the year, even if it’s just one or two flakes, it’s kind of a big deal.
Overall, between one and two inches of rain is possible in some places over the next several days. As of right now, it looks as though the system will move out late Saturday with sunshine and warmer temperatures (in the 60s) returning by early next week. Stay tuned for the very latest updates.
