.DISCUSSION...
...Yellowstone NP and Teton dispatch areas (includes fire weather
zones 140...414...415...and 416)...
Isolated showers and thunderstorms persist through Monday evening,
particularly across Zone 140. The approach of a weather disturbance
provides a better chance of showers and thunderstorms Tuesday
afternoon and evening. There is the potential for wetting rain in
Zone 140, with decreasing chances moving south. A steady cool down
comes Tuesday and especially Wednesday behind the weather system.
...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...
Isolated showers and thunderstorms, with better coverage across Zone
286, persist Monday evening and even linger over the far northern
Bighorn Basin into Tuesday morning. Gusty outflow wind will be the
primary hazard. A cold front pushes south through the dispatch area
Tuesday morning setting the stage for a better chance of afternoon
and evening showers and thunderstorms. A steady cool down comes
Tuesday and especially Wednesday behind the cold front.
...Casper dispatch area (includes fire weather zones 277...278...
279...280...281...285...289...and 300)...
Areas east of the Continental Divide will see isolated showers and
thunderstorms Monday afternoon and evening. Passage of a cold front
from the north Tuesday provides cooler temperatures and a better
chance of showers and thunderstorms across this region during the
afternoon and evening. Across the southwest fire zones, warm and
breezy conditions prevail through Tuesday, although there will be at
least isolated showers and thunderstorms Tuesday afternoon and
evening. Gusty outflow wind would be the main hazard across the
southwest. The cold front makes a final push through the southwest
zones Tuesday night.
...Thunderstorms imply strong gusty and erratic winds...
