838 FNUS63 KFSD 240703 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 203 AM CDT Mon Aug 24 2026 .DISCUSSION... Scattered showers and storms will continue to progress east- southeastward through this morning, bringing a threat of locally heavy rain. Southerly winds around 8-12 mph will help keep dew points in the 60s and 70s, keeping relative humidity high and thus the fire danger low. Additional showers and storms may move in tonight, but confidence is low in this potential. A cool front moves across the area on Tuesday, turning winds to the west and then northwest and drying the area out a bit. This will mean relative humidity values drop as low as 35-40% mainly north of I-90 where winds will also gust upwards of 25-30 mph Tuesday afternoon, resulting in a moderate GFDI across mainly northern and western parts of the area.
