SIOUX FALLS, S.D. — A damp, early-morning chill settled over the Sioux Empire on Saturday as a blanket of cloud cover kept the sky muted. The quiet start won’t last long: a more active stretch arrives late Sunday into Monday, marking the first real nudge toward November’s colder feel.
The National Weather Service in Sioux Falls expects the weekend to stay mild, with Sunday’s highs reaching the mid-60s. South-southeast winds will build through the afternoon, with gusts around 25 to 30 mph ahead of an approaching cold front. As that front pushes in late Sunday night, widespread showers are set to spread across southeast South Dakota, with the most persistent rainfall likely Monday morning.
Drivers along I-29 and I-90 should anticipate wet pavement, patchy ponding, and reduced visibility into early Monday afternoon. Severe weather isn’t expected, but steady rain and brisk gusts could slow commutes and disrupt outdoor plans. Once the front clears, cooler air sweeps in quickly. Highs tumble to the upper 40s Tuesday, with morning lows in the upper 30s—a chilly reminder that winter is getting close.
High pressure rebuilds by midweek, bringing back sunshine, lighter winds, and a modest warm-up. Temperatures edge into the low 50s Wednesday, setting the stage for crisp, calm conditions as Halloween approaches.
Following this brief rainy period, South Dakota’s weather turns drier and seasonable, with a colder November still looming just ahead.
