582 FNUS63 KFSD 142144 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 344 PM CST Fri Nov 14 2025 .DISCUSSION... Issued at 300 PM CST Fri Nov 14 2025 Mildly gusty winds, very warm temperatures for November, and low relative humidity continue into the late afternoon today. Winds have underperformed somewhat today, with only occasional gusts greater than 25 mph in south central South Dakota, and northwestern Iowa. This afternoon have trended the winds down from NBM guidance a little to better match current conditions. Winds have also helped to mix down the very warm temperatures (16-20 C) in the 925 mb level. This worked to warm afternoon highs into the 70s and even 80s. The air mass through the column today has remained very dry, allowing minimum relative humidity values to fall to less than 25% for areas west of the James River Valley. While these are near critical Fire Weather conditions, the fact that the winds have underperformed has prevented the need for an eastward expansion of the Red Flag Warning this afternoon. Gregory county remains the only county in a Warning which continues through 6pm CST. Cooler temperatures and increased surface moisture will keep Fire Weather conditions at bay for the rest of this weekend and much of the upcoming week. Do not leave open fires unattended.
