Heavy Snow, Wind Likely Later Today

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.

Major Spring Storm System to Bring Rain, Snow and Wind

It is going to be an absolutely gorgeous day! However, once again the sunny, mild weather will only last about a day. We have big changes in the forecast for tomorrow. In fact, a Winter Storm Watch is in effect for parts of northeast and east central South Dakota late tonight and tomorrow.

Let’s talk about the good stuff first: Today will be partly cloudy with afternoon temps ranging from the low 60s in Sioux Falls and across the tri-state area, to the upper 60s and low 70s across central and south-central South Dakota. Unfortunately, like a swerving, speeding, fist shaking nut-job in your rearview mirror, our next system is coming up fast! And, just like that aforementioned individual, the system will not be pleasant.

A fairly significant spring storm system will move across the plains tonight through tomorrow. There’s no doubt that there will be a considerable amount of moisture with the system. But, as it is with any spring system, the big question is, “how much rain vs. snow.” As of right now, I think that the Sioux Falls area will get a good mix. There will be between 0.25″ and 0.50″ of total precip. with about 1-3 inches of snow.

Further north and west of Sioux Falls, where temperatures will be colder, there will be more snow. As of right now, I think the heaviest snow will fall along a l9ine that extends from Pierre to Sisseton. Some places could get 4 to 6 inches by the end of the day tomorrow.

In addition to the rain and snow, tomorrow will also be very windy. North wind gusts from 35 to 45 mph are possible throughout the day and into tomorrow night. This will create areas of blowing and drifting snow. Stay tuned for the latest details on this developing storm system.

Wednesday will be breezy and colder with scattered showers and high temps in the low 40s. We will be back in the 50s on Thursday with another chance of rain or snow on Friday. The weekend ahead will be colder with highs in the upper 30s to low 40s.

Significant Winter Storm to Impact MN/IA

I’m keeping an eye on a huge winter storm system that will impact much of Minnesota and Iowa tonight and tomorrow.

As of right now, I think SIoux Falls will get about an inch of snow overnight through tomorrow. Snow will be heavier east of Sioux Falls. Warnings and advisories are in effect for much of MN/IA. Many Minnesota schools have already closed for tomorrow.
