Sioux Falls, SD – Spring weather conditions bring a high fire risk across South Dakota starting Monday afternoon, especially west of I-29. As dry conditions persist, a combination of gusty winds and low humidity will increase the chances of wildfires spreading quickly, posing a significant hazard to outdoor activities and travel.
According to the National Weather Service, southerly winds of 20 to 30 mph combined with humidity levels as low as 20 to 30 percent will set up a high fire risk for many areas. This threat will peak in the afternoon, so residents should avoid outdoor burning and be cautious of sparks or discarded cigarettes.
In Sioux Falls and surrounding regions, winds will gust from the south, bringing dry air that heightens the fire threat across open fields and grasslands. The fire risk will remain elevated through Monday evening, with winds calming later in the night. Although no immediate spotter activation is expected, residents should remain alert and report any signs of smoke or wildfires to local authorities.
Looking ahead, the remainder of the week looks to bring warmer temperatures and clear skies. Temperatures on Monday will reach 78°F, with highs of 80°F on Tuesday and near 80°F by Wednesday, making for a beautiful but dry start to the week. The risk of fire danger is expected to decrease after Monday, but any outdoor activities west of I-29 should be monitored closely until the wind dies down.
Extended 5-Day Forecast:
Monday: High of 78°F, sunny skies, light winds becoming gusty by afternoon.
