A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.

...CRITICAL FIRE WEATHER CONDITIONS THURSDAY ACROSS PORTIONS OF NORTHEASTERN WYOMING AND WESTERN SOUTH DAKOTA... .Anomalously warm temperatures (70s to low 80s), very dry air (relative humidity as low as 10 percent), and gusty west winds (gusts 25 to 35 mph) will result in critical fire weather conditions Thursday. Humidity recovery will be poor tonight through daybreak Thursday, particularly for the Black Hills and northeastern Wyoming. Strongest winds are expected across southern Campbell County and northwestern South Dakota where gusts to 35 mph are expected. Lesser confidence in critical gusts elsewhere, however between the low humidity, dry antecedent conditions, and transient critical gusts, critical fire weather conditions can be expected for much of the area.
