.DISCUSSION...
Near-critical fire weather conditions with localized critical
conditions will continue through late this afternoon over portions
of northeastern Wyoming and far southwestern South Dakota.
Relative humidity values have fallen below 15 percent, with wind
gusts remaining around 25 mph. Winds should diminish later this
afternoon, with relative humidity values gradually increasing
thereafter. Breezy downslope winds ahead of an approaching front
will lead to poor relative humidity recovery over portions of the
Black Hills and foothills tonight.
Conditions will improve somewhat tomorrow, though elevated fire
weather conditions cannot be ruled out over portions of
southwestern and south central South Dakota. Milder temperatures
and chances for precipitation return late tomorrow into the
weekend, with best chances for wetting rains over southwestern
portions of our area (Black Hills, northeastern Wyoming, and
southwestern South Dakota).
