...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Warm with mostly light winds across the Dispatch area. Chances for
showers and thunderstorms will begin to develop in the afternoon
lingering through the evening. Coverage will be limited, with
isolated chances of 10 to 30%. However, the dry atmosphere will
likely hinder wetting rains leading to mostly virga showers and dry
thunderstorms. This will create the possibility for some strong
gusty outflows winds nearby any developing showers or thunderstorms.
Gusty outflow winds of 40 to 50 mph cannot be ruled out in some
locations. An influx of above normal moisture is expected to arrive
by Wednesday through Friday leading to increased chances for wetting
rains.
...Cody dispatch area (includes fire weather zones 275...276...
