033 FNUS63 KFSD 100954 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 454 AM CDT Fri Oct 10 2025 .DISCUSSION... Less windy today (north-northeast 5-10 mph), but relative humidity values will be down to around 30% this afternoon as dry air filters in behind a frontal passage that occurred this past night. Overall, a moderate fire danger will be in place today due to the lower RH values. Winds will pick up again this weekend, with gusts of 25-35 mph likely on both Saturday and Sunday area-wide. RH values will be lowest (around 30%) along and east of I-29 on Saturday, but the gusty winds will lead to a widespread high fire danger area-wide Saturday afternoon. On Sunday, the lowest RH values (again around 30%) will be in south-central South Dakota. Very warm temperatures and gusty winds will once again lead to a high to locally very high GFDI Sunday afternoon. Rain chances increase on Sunday and could limit the fire danger in some areas, but confidence is low- to-medium on where the best chance of rain will be at this time.
