.DISCUSSION...Moisture remains in place over the region today, bringing

another day of shower and thunderstorm activity over the high 

terrain. Boulder Mountain will remain the hotspot for showers and 

thunderstorms to begin developing after 1100, with storms favoring

a southwest progression after forming over the high plateau. 

While a majority of storms are anticipated to pass to the north 

and west of the fire area, there will still be an enhanced risk of

frequent lightning strikes around the fire area, likely striking 

outside the core of the storm. Any storms that do end up moving 

over the fire area will likely bring moderate to heavy rainfall. 

Gusty outflow winds are expected this afternoon as storms form 

over the high plateau and drift slowly off the terrain, with the 

most likely outflow wind direction coming from the northwest.

Shower and thunderstorm activity is expected to continue until 

around 2000, however, there will still be a low (30-40%) chance

for showers to move over the fire overnight.
