.DISCUSSION...

...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...

An influx of moisture will begin to work its way into the region
today. Most locations are expected to remain dry with seasonable
temperatures. Isolated showers and thunderstorms will develop this
afternoon and evening mainly across zones 414 and 416. A small
chance around 10 percent for wetting rains is possible over the far
southern portions of these zones. Relative humidity will remain
above critical levels. Wind will be light to moderate except in and
around any shower or thunderstorm. Mixing and smoke dispersal will
be generally good to excellent in the afternoon. Chances for showers
and thunderstorms along with wetting rains increase throughout the
upcoming week.

...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...

An influx of moisture will begin to work its way into the region
today. Most locations are expected to remain dry with seasonable
temperatures. Unfortunately the bulk of the precipitation will
remain to the south of the dispatch area. However, an isolated
shower or thunderstorm cannot be ruled out across higher elevation
zones and portions of zones 283 and 289. Relative humidity will
remain above critical levels. Wind will be light to moderate except
in and around any shower or thunderstorm. Mixing and smoke dispersal
will be generally good to excellent in the afternoon. Chances for
showers and thunderstorms along with wetting rains increase
throughout the upcoming week.

...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...

An influx of moisture will begin to work its way into the region
today. Most locations are expected to remain dry with seasonable
temperatures. Isolated showers and thunderstorms will develop this
afternoon and evening mainly across zones 277, 278, 279, and 289. A
small chance around 10 percent for wetting rains is possible over
some isolated portions of these zones. Relative humidity will remain
above critical levels. Wind will be light to moderate except in and
around any shower or thunderstorm. Mixing and smoke dispersal will
be generally good to excellent in the afternoon. Chances for showers
and thunderstorms along with wetting rains increase throughout the
upcoming week.

...Thunderstorms imply strong gusty and erratic winds...
