Fast-Moving Clipper System to Drop 3–6 Inches of Snow Across South Dakota, Minnesota, Iowa, and Illinois From Saturday Afternoon Through Sunday

SIOUX FALLS, SOUTH DAKOTA — A strengthening clipper system is expected to sweep across the Northern Plains and Upper Midwest from Saturday afternoon through Sunday, bringing a broad swath of light to moderate snowfall across South Dakota, Minnesota, Iowa, and Illinois. Forecast confidence has increased as the storm track remains consistent, and meteorologists now expect a higher likelihood of 3 inches or more across the central corridor of the region.

Snowfall rates may approach 1 inch per hour at times, making road conditions slippery and reducing visibility, particularly during peak snowfall late Saturday and early Sunday.

Snowfall Forecast: 3–6 Inches in the Central Band

Based on the latest forecast map:

• 3–6″ of snow is likely from central South Dakota through southern Minnesota and into northern Iowa, extending toward northwest Illinois, including areas near Rockford.
• 1–3″ is expected farther south into Des Moines, Omaha, Davenport, and Peoria.
• Under 1″ is likely for areas on the southern and northern fringes, including Chicago, Milwaukee, and northern North Dakota.
• A separate Lake Effect band up to 6 inches may develop near Lake Superior, affecting areas from Marquette to Sault Ste. Marie.

The clipper’s quick motion means totals won’t be exceptionally high, but the intensity of snowfall bursts could still create significant short-term impacts.

Travel Impacts Expected Despite Light Winds

While winds are not forecast to be particularly strong, the snow itself will be dry and fluffy, creating ideal conditions for:

• Blowing snow across open highways
• Drifting in rural areas
• Rapidly changing visibility
• Slippery untreated roads

Even a few inches of this powdery snow can produce hazardous travel, especially on interstates such as I-90, I-29, I-35, and I-94.

Drivers heading through South Dakota, Minnesota, Iowa, or Illinois Saturday night should anticipate extra travel time and changing conditions.

Impact on Concertgoers, Touring Artists, and Venues

For the music community across the Upper Midwest, the timing of this clipper system may cause:

• Delays for fans traveling to evening shows or weekend performances
• Difficult load-ins or equipment transport due to blowing snow and slick surfaces
• Reduced turnout at smaller venues in rural or suburban areas
• Slowdowns for touring buses and trucks moving between cities such as Sioux Falls, Minneapolis, Des Moines, and Rockford

Even moderate snowfall can disrupt event schedules, especially for artists on tight regional tours.

Storm Strength Increasing as It Approaches

Forecasters note that the system has trended stronger over the last 48 hours, raising confidence that more areas will see accumulating snow. While not a major winter storm, the clipper’s speed and snowfall rates mean it will still be disruptive for weekend travel across the northern U.S.
