Sioux Falls, and much of the southeastern side of South Dakota, is expected to see anywhere from a trace of snowfall up to 2 inches Monday, according to the National Weather Service office.
According to the agency’s latest forecast, rain and snow will develop Monday morning, with a brief mix of precipitation that could result in slick surfaces. That rain, however, will transition to snow by mid-morning, moving northwest to southeast as the system heads into Iowa in the early evening hours.
The risk for hazardous travel conditions for the area is growing, the NWS stated.
When will the storm hit the area?
The beginning of the storm is expected to start at about 4 a.m. Monday, but peak timing for the storm is expected between noon and 9 p.m., according to the NWS.
The system will end sometime between 4 a.m. and 6 a.m. Tuesday.
When will Sioux Falls see rain transition to snow?
The highest snowfall amounts, possibly 2 to 4 inches or more, are expected near and west of the James Rivery Valley, the NWS stated.
Most of the area will see light to moderate rain through about noon or later. Then, the rain will change over to snow by 3 p.m., though the exact timing isn’t certain, the forecast states.
By 6 p.m., the Sioux Falls area will see a full transition to light or moderate snowfall, the prediction states.
A variety of precipitation types will impact the area on Monday. Light to moderate rain should dominate the midday hours, but cooling through the afternoon and evening will bring a change to snow, generally from northwest to southeast.
Have any watches or warnings been issued?
As of 5 p.m. Sunday, areas to the west of Mitchell and Huron are under a winter weather advisory from 6 a.m. to 9 p.m. Monday, where the areas could see up to 4 inches of accumulation from the storm.
No warnings or watches have been issued for Minnehaha or Lincoln counties at this time.
Mild late December weather will soon be a thing of the past, as the area sees a downward trend in temperatures into 2025. A wintry mix Monday may result in hazardous winter travel conditions at times.
What’s expected after the storm?
After the storm moves through, the area will see temperatures plummet as the new year kicks off. Then, chances for snow showers are anticipated to return by Saturday, through the weekend. The average high will be 28 degrees while the average low is expected to be 10 degrees.
