Sioux Falls, South Dakota – Southerly winds gusting up to 30 mph and dry air are fueling an elevated fire danger west of Interstate 29 through Monday, prompting warnings from local officials across South Dakota. The combination of cured fuels, unseasonably warm temperatures, and low humidity is creating conditions ripe for fast-moving grass fires.
According to the National Weather Service in Sioux Falls, highs will range from the 70s to low 80s through Friday, with overnight lows in the 40s to low 50s. Fire weather concerns remain highest west of I-29 through early Monday. From Tuesday onward, isolated rain showers may develop over the Missouri River Valley and into northwestern Iowa, but significant rainfall remains unlikely.
Areas most at risk include communities along U.S. Highway 81 and smaller towns west of Sioux Falls. Residents are urged to avoid outdoor burning and to secure items that could spark under dry, windy conditions. Farmers and ranchers should monitor local alerts and remain cautious when using machinery near grassy areas.
Dry and breezy conditions are expected to persist into midweek. Further fire weather advisories may be issued if winds increase or humidity drops again.
