.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Showers and thunderstorms will be widespread today with all zones
likely seeing some convection. Zones 140, 415 and 416 will have the
better chances. Due to the dry atmosphere, chances of wetting rains
will be low with these showers and storms. Gusty outflow winds of
40+ mph will be the primary hazard. These storms will wane after
1800, with an isolated shower possible midnight.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Showers and thunderstorms will mostly be widespread today with zones
286, 287 and 288 having the better chances. Due to the dry
atmosphere, chances of wetting rains will be low with any showers
and storms. Gusty outflow winds of 40+ mph will be the primary
hazard with any nearby developing storms. These storms will wane
after 1800, ending across the area by sunset.

279...280...281...285...289...and 300)...
