We have a very active forecast the next few days as wave of light to moderate snow mix with periods of freezing drizzle today and tomorrow. Winter weather advisories have been posted today in the blue shaded areas, including Aberdeen, Pierre, Chamberlain, Mitchell, and Winner. Snowfall of 2-5″ is expected with occasional light icing with freezing drizzle. A winter storm watch has been issued for Saturday night into Sunday for areas of SW MN and NW IA for ground blizzard conditions. This watch may be expanded farther west as wind forecasts expand on Sunday across eastern South Dakota.
Snowfall the next 24 to 36 hours will add up to 2-5″ in many spots. Sioux Falls would get most of the snow forecast overnight tonight, but another surge in NW IA Saturday night may clip Sioux Falls as well.
The wind on Sunday will blow around the snow on the ground and it will miserable. Gusts over 50 mph are looking more and more likely and that will whip around the snow into drifts and piles, creating dangerous travel conditions. The depth of the snow before the wind will the biggest problem. Stay alert to the latest wind forecasts the next 36 hours as we fine-tune the details.
The weather will be much colder again next week. This will be a tough weather pattern the next few days.
