.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Warm and mostly dry conditions across the dispatch area today. Winds
will increase this afternoon with periodic gusts of 20 to 30 mph.
Lighter winds return by the evening prevailing through the overnight
hours. An isolated shower cannot be ruled out over portions of zone
140 this afternoon but overall dry and warm conditions prevail into
the first half of the week.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Most of the dispatch area will see warm and dry conditions prevail
into the first half of the week. However, scattered showers and a
few isolated thunderstorms cannot be ruled out this afternoon and
evening mainly in zones, 286, 276, 275, 282, and 285. Winds increase
this afternoon with periodic gusts of 20 to 30 mph possible through
the evening. As mentioned earlier warmer and drier conditions
persist over the region through much of the first half of the week.
...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...
Warmer and mostly dry conditions are expected across the dispatch
area today. The only exception to this will be portions of zones
281, 285, 280, and 300 where scattered showers and thunderstorms are
possible this afternoon and evening. Winds increase this afternoon
with periodic gusts of 20 to 30 mph through the evening. Low RH
values and breezy winds will lead to near elevated fire weather
conditions is portions of zones 289, 278, 279, and 277. Warmer
temperatures and drier conditions are likely to persist into the
first half of next week.
...Thunderstorms imply strong gusty and erratic winds...
