.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Temperatures this afternoon (Saturday) will be a few degrees
warmer than yesterday (Friday) and due to increasing atmospheric
moisture, afternoon relative humidities will actually be a few
percentage points higher. Scattered showers and thunderstorms now
developing over the south (Zone 414) move toward the north (Zone
140) through the evening and overnight. Chances for a wetting
rain are low (10%), but the higher terrain could see light
precipitation with any passing shower, alongside brief erratic
outflow gusts 35 to 45 mph. Sunday will be a few degrees cooler,
and feature another chance for scattered thunderstorms.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Temperatures this afternoon (Saturday) will be about 10 degrees
warmer than yesterday (Friday) with relative humidities 5 to 10
percentage points drier. Winds will be light today with gusts
generally remaining below 15 mph. Despite minimum RHs in the 12 to
18 percent range, the lack of winds should keep fire weather
concerns lower. Sunday will be a few degrees warmer yet, and
feature a 20 to 30% chance for afternoon showers and
thunderstorms.
...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...
Vastly different conditions depends on where you are in the Casper
Dispatch area. For the High Plains, temperatures this afternoon
(Saturday) will be about 10 degrees warmer than yesterday (Friday)
with relative humidities about 10 percentage points drier. For the
High Desert, temperatures this afternoon (Saturday) will be
similar to yesterday with relative humidities about 5 percentage
points wetter. Background winds will be light today with gusts
generally remaining below 15 mph, but 35 to 45 mph are likely in
the vicinity of storms over the High Desert. Sunday features 20
to 30% chance for afternoon showers and thunderstorms.
...Thunderstorms imply strong gusty and erratic winds...
