Elevated fire weather conditions may be possible over portions of
southern Wyoming through 8 PM, due to low relative humidity and gusty

mainly be confined to the Absaroka and Bighorn Ranges along with
lower elevation locations east of these mountains.

combine with breezy westerly wind to create critical fire weather

daytime highs at or above seasonal normals, and low relative
humidity will continue to produce elevated to perhaps critical fire
weather conditions across portions of southwest and central Wyoming.

conditions according to Standard Operating Procedures.
