Sioux Falls, SD – A dramatic weather change is expected across South Dakota this weekend, with summer-like warmth on Friday giving way to potential snow by late Saturday night.
According to the National Weather Service in Sioux Falls, Friday’s highs could soar into the mid-80s, threatening to break longstanding temperature records. Strong winds combined with dry conditions will also elevate fire danger to very high levels, prompting caution across the region.
By Friday evening, the weather will take a sharp turn as showers and thunderstorms develop, with some storms potentially reaching severe levels. The NWS projects a 60–80% chance of widespread rainfall on Saturday, with at least half an inch of precipitation expected in many areas.
Temperatures will plunge Saturday night, dropping into the 20s and allowing for a mix of rain and snow. Snow may fully develop into Sunday morning, though forecasters anticipate less than one inch of accumulation.
Residents are urged to stay weather-aware and take necessary precautions, especially in areas at risk for fire or travel disruptions. The shift from record heat to wintry weather over just 48 hours underscores the importance of preparing for rapidly changing spring conditions across the Plains.
