South Dakota, USA – A chilly, damp breeze sweeps across Sioux Falls before sunrise, scattering wet leaves over driveways as a gray deck of clouds hints at an early Winter Tease forming to the west. Light rain builds through the day, and Tuesday may deliver a brief mix of drizzle and snow that could nudge travel times higher as Thanksgiving movements begin.
According to the National Weather Service in Sioux Falls, bands of rain expand from northeast Nebraska into southeast South Dakota and northwest Iowa this afternoon. Drivers should watch for slower patches on I-29 and I-90, especially where drizzle clings to cold windshields. Residents heading to school or early holiday errands should keep layers dry and carry a scraper in case a light glaze develops after sunset.
According to meteorologists, a subtle shift in wind direction tonight pulls colder air toward the region. Models hint at a small window for snowflakes Tuesday morning, mainly north of the city and into southwest Minnesota. Accumulation looks minimal, but even a short slushy burst can reduce traction on rural roads. The day stays brisk and cloudy as temperatures cool toward freezing in sheltered valleys.
According to South Dakota DOT, crews will monitor bridges and overpasses late Tuesday, focusing on areas east of Sioux Falls where drizzle may linger. Travelers leaving early for Thanksgiving should build in extra time, check updated advisories twice daily, and stay alert for sudden visibility changes under low clouds.
The pattern relaxes midweek, and Wednesday looks drier with thinning clouds and lighter winds. A calmer stretch may settle in for the weekend, offering decent November weather for leaf cleanup, early decorating, or regional travel. After all, winter edges closer, and another pattern shift may arrive next week.
