.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
A cold front will slowly drop southward toward the area and bring
a few showers and thunderstorms, with chances ranging from 1 in 3
in Zone 140 to 1 in 5 in the southern zones. The chance of wetting
rain remains very low. Relative humidity will remain above critical
levels. Breezy conditions will develop in the afternoon. Mixing
and smoke dispersal will be generally excellent in the afternoon.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
***RED FLAG WARNING IN EFFECT FOR ZONES 283...288 AND 289 UNTIL
FROM 12 PM TO 8 PM TODAY***
A combination of a gusty southwesterly wind and humidity falling to
under 15 percent will bring critical fire weather to the southern
zones this afternoon. Elsewhere, elevated fire weather is possible
but humidity and wind is not expected to reach criteria. Isolated
showers and thunderstorms (around a 1 in 3 chance) may bring wind
gusts past 40 mph and hail across the northern zones this afternoon.
Mixing and smoke dispersal will range from good in the northern zones
to excellent in the southern zones. Higher humidity on Wednesday
should reduce fire weather concerns for all zones.
...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...
***RED FLAG WARNING IN EFFECT FOR ZONES 277...278...279...280 AND
289 FROM 12 PM TO 8 PM TODAY***
A combination of a gusty southwesterly wind and humidity falling to
under 15 percent will bring critical fire weather all zones with
critical fuels except Zone 281. Elsewhere, elevated fire weather is
possible. Isolated showers and thunderstorms (around a 1 in3 chance)
may bring wind gusts past 40 mph in Zones 281 and 285 this afternoon.
Elsewhere, the chance of a shower or thunderstorm is less than 1 out
of 5. Mixing and smoke dispersal will range from good in the northern
zones to excellent in the southern zones. Higher humidity should ease
fire weather concerns in the zones East of the Continental Divide on
Wednesday.
