Sioux Falls, South Dakota – Strong winds and unseasonably warm air are creating elevated fire danger across eastern South Dakota today, with conditions expected to worsen Thursday before a sharp turn toward colder temperatures and snow by late week. Drivers, farmers, and anyone working outdoors around Sioux Falls should prepare for rapidly changing conditions that could affect travel and safety.
According to the National Weather Service in Sioux Falls, northwest wind gusts today could reach 40 to 50 mph, combining with dry fuels and warm temperatures in the mid-40s to mid-50s to increase the risk of fast-moving grass fires. Winds remain strong Thursday as temperatures fall, with a 30 percent chance of light snow developing late in the day and into Friday.
By Friday, colder air settles firmly over the region, with highs dropping into the mid-20s and lows falling into the single digits. Light snow and gusty winds could lead to areas of blowing snow, especially on open stretches of Interstate 29, Interstate 90, and rural highways across Minnehaha, Lincoln, and Moody counties. While widespread heavy snow is not expected, even minor accumulation could reduce visibility and create slick spots.
Colder and breezy conditions persist through the weekend, with highs Saturday struggling to reach the teens and early morning wind chills dipping below zero. Residents are urged to secure loose objects, avoid outdoor burning, charge devices ahead of potential travel delays, and use caution on area roads late Thursday through Friday.
Additional advisories or fire weather statements may be issued as conditions evolve, and residents should monitor updates from the National Weather Service through the weekend.
