234 FNUS63 KFSD 120943 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 443 AM CDT Sun Oct 12 2025 .DISCUSSION... Breezy conditions continue across the area today, with gusts of 25-35 mph expected. Locally higher gusts up to 40 mph can`t be ruled out. Temperatures are also expected to be much warmer, with highs in the mid-70s to low-80s this afternoon. This will all lead to a high fire danger across the area, but there are some limiting factors. First, showers are possible (30-60% chance) this morning along and east of the James River, and again this afternoon mainly east of I-29 (20-50% chance). Relative humidity values this afternoon will also generally be higher today, around 40-60%. However, some spots along the Missouri River valley into south-central South Dakota could see RH values drop to 35% so there could be a locally enhanced fire weather danger in those areas. Cooler temperatures and lighter winds arrive tonight into tomorrow, so the fire weather concerns will be much lower heading into Monday. More rain chances are set to return on Tuesday as temperatures remain cool.

The Grassland Fire Danger Index will reach the high category this afternoon. Unfavorable weather conditions and low moisture content of grasses, and other dry organic material on the ground, indicate that there is a high potential for a fire to spread.. Outdoor burning should be restricted to early morning or evening hours, when wind speeds are usually lower and the relative humidity is higher. OUTLOOK FOR COLUMBUS DAY AFTERNOON...The Grassland Fire Danger Index will reach the moderate category. The grassland fire danger product reflects fire danger for native grasses.
