.DISCUSSION...

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

The majority of showers and thunderstorms end this evening.
Increasing moisture keeps light rain shower chances (15-20%) through
the night, with increasing shower and thunderstorm chances late
Tuesday morning and afternoon. Tuesday temperatures are comparable
to Monday, with minimum humidity trending up to 10 percent higher.
The chance of wetting rain is low overall, but localized moderate to
heavy rain could bring pockets of wetting rain.

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

Isolated (15-20%) showers remain overnight, primarily for the higher
elevations and nearby lower elevations. Shower and thunderstorm
chances (20-40%) become more widespread by Tuesday afternoon as
moisture increases across the area. Tuesday temperatures are
comparable to Monday, with minimum humidity trending 5 to 10 percent
higher.

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

Isolated showers and thunderstorms remain around zones 280, 289, and
300 through about midnight. Moisture increases from the southwest
tonight, with increasing light rain chances starting around zones
277, 278, and 279 after 0100. More widespread 15 to 30 percent
chances for showers and thunderstorms occur for all zones through
Tuesday. Tuesday temperatures are comparable to Monday, with minimum
humidity trending 7 to 10 percent higher.
