Sioux Falls, SD – Light mixed precipitation is expected across portions of South Dakota and northern Nebraska today, with slick travel conditions possible despite generally low snowfall and ice totals, according to the National Weather Service in Sioux Falls.
Forecasters say the wintry mix will be focused south of Interstate 90, particularly along the Missouri River Valley into northern Nebraska. Precipitation may fall as a mix of snow, sleet, and freezing rain, with accumulations remaining light. Snow totals are expected to stay under one inch, while ice accumulations may reach only a few hundredths of an inch.
While amounts are limited, even small ice accumulations can create hazardous driving conditions. The National Weather Service warns that slick roadways and reduced visibility are possible, especially during the late morning and early afternoon hours when impacts are expected to peak, roughly between 8 a.m. and 5 p.m.
A Winter Weather Advisory is in effect for parts of south-central South Dakota through northern Nebraska, where confidence is highest that mixed precipitation will affect travel. Conditions may vary significantly over short distances, depending on precipitation type and timing.
Drivers are urged to check road conditions before traveling and to be prepared to adjust or delay plans if conditions worsen. Untreated roads, bridges, and overpasses are most likely to become slick during periods of freezing drizzle or sleet.
The National Weather Service notes that some uncertainty remains regarding the exact precipitation type and timing, which could influence where the greatest impacts occur. Temperatures near freezing will play a key role in determining whether areas see more snow or ice.
Beyond today, quieter weather is expected to return, with no major winter systems immediately following this event. However, residents are encouraged to remain weather-aware, as winter conditions can change quickly across the northern Plains.
