.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
The trend will be toward warmer and drier conditions Wednesday
and Thursday. Breezy westerly wind 15 to 25 mph will be common,
especially in the mountains, from late morning until sunset.
Warmer and breezier conditions Thursday afternoon will decrease
relative humidity. Drier air aloft will hinder the development of
any showers or thunderstorms.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Cooler air remains entrenched across the dispatch area Wednesday
afternoon and tonight. Daytime temperatures will be 12 to 25
degrees below seasonal normals. Cloud cover clears Wednesday
afternoon leaving a mostly clear sky overnight. Other than a few
afternoon and evening showers and thunderstorms over mainly zones
286 and 288, conditions look mostly dry through Thursday. Seasonal
temperatures return to most areas Thursday and minimum relative
humidity will be much lower than Wednesday. Favorable west-
northwest wind Thursday afternoon will lead to elevated fire
weather conditions in zones 283, 286, and 288.
...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...
Cooler air remains entrenched across the north half of the
dispatch area Wednesday afternoon and tonight. Daytime
temperatures will be 15 to 30 degrees below seasonal normals.
Cloud cover will be slow to clear in zones 280 and 281, likely
lingering through Wednesday evening. Over the south half, seasonal
temperatures, gusty westerly wind, and minimum relative humidity
in the teens prevails through Thursday. This leads to elevated
fire weather conditions each afternoon and evening. Other than a
few afternoon and evening showers and thunderstorms over mainly
zones 279 and 289, conditions look mostly dry through Thursday.
Temperatures do rebound to seasonal readings Thursday under a
mostly sunny sky.
...Thunderstorms imply strong gusty and erratic winds...
