South Dakota wakes up under a muted winter sky as low clouds drift over frozen fields and city streets. Light flakes flicker in and out of view, barely audible as they tap windshields and sidewalks.

A Weather Alert is in effect across the Sioux Falls region as winter conditions linger through the day. According to the National Weather Service, light snow continues east of I-29 this morning, with a dusting possible. Visibility may briefly drop during passing flurries, especially during early travel hours. Winds increase slightly through the morning, adding a sharp edge to the cold air.

Temperatures hover near the upper 30s this afternoon, but cold ground conditions mean even small amounts of snow can create slick spots. Pockets of freezing drizzle or a light wintry mix may develop into the mid-morning hours, creating patchy ice on untreated roads, parking lots, and sidewalks. Drivers should slow down and increase following distance, particularly on bridges and ramps.

Tonight stays mostly cloudy with lows dropping into the teens. That cooling raises the risk of refreezing where snow melts during the day. Plan ahead for the Monday morning commute.

Monday remains quiet but colder, with highs near 30 degrees under mostly cloudy skies. Monday night brings another chance for light snow, though accumulations look minor. Tuesday trends similar, with clouds holding firm and highs in the upper 20s before clearing begins.

By midweek, conditions gradually improve. Wednesday stays cold but dry, and Thursday delivers a noticeable warm-up with sunshine and highs climbing into the mid-40s. No significant snow systems are expected through the end of the week.

Meteorologists continue monitoring broader winter patterns across the Northern Plains. For now, Sioux Falls faces a manageable but slippery stretch of winter weather.

Take extra care on the roads today and tonight. How are conditions where you’re driving this morning?
