768 FNUS63 KFSD 281018 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 418 AM CST Fri Feb 28 2025 .DISCUSSION... Issued at 350 AM CST Fri Feb 28 2025 Deep mixing behind a couple frontal boundaries will bring wind gusts of 40 to 50 mph across the area during this afternoon and evening. In addition, with temperatures into the 50s across much of the area and drier air behind the frontal boundaries, afternoon RH will drop to 30 to 35 percent through the western James River Valley, the Missouri River Valley, and northwestern Iowa. With deeper mixing, RH values could drop even lower than this over that area. In spite of the fact that RH is expected to be higher than 20-25 percent, with the aforementioned very strong winds any fire starts could exhibit explosive growth. In light of that, issued a Red Flag Warning for the above areas. People are urged to exercise extreme care with respect to outdoor activities that could cause grass fires. Avoid equipment that can cause sparks near dry grass or brush. Do not toss cigarettes on the ground. Report new fires quickly to the nearest fire department or law enforcement office.
