A significant spring/winter storm system continues to develop and move toward our region this morning. A Winter Storm Warning is in effect for this afternoon and tonight for portions of eastern South Dakota, including Sioux Falls, much of Minnesota and portions of northwest Iowa. A Winter Weather Advisory is in effect for areas adjacent to the warning. Check our weather alerts section at KSFY.com for specific county by county information on watches, warnings and advisories.
It is already misting in Sioux Falls this morning and with temperatures dropping, roads will likely be slippery for your commute.
Rain will mix with, then change to snow later this morning or early this afternoon. Snow will be heavy at times with 1 to 3 inches of accumulation possible through 5 PM. Heavy snow will continue through the night tonight with an additional 2 to 4 inches of accumulation by tomorrow morning. In addition to the snow, strong north to northwest wind gusts to 35 or 40 mph will create blowing snow at times.
As of right now, I expect overall snowfall totals of 3 to 7 inches in Sioux Falls, with heavier amounts across parts of Southwest and central Minnesota.
Snow will end by sunrise tomorrow but the wind will continue to gust to 35 or 40 mph through lunchtime tomorrow.
After we get through tomorrow, things will improve quickly. Saturday will be partly cloudy with high temps in the mid 40s. A few scattered showers are possible Sunday into Monday with high temps in the 50s. By the middle of next week, high temps will soar into the low to mid 60s. Parts of central South Dakota could reach the 70s by the middle of next week.
