...CONFIDENCE INCREASES FOR THUNDERSTORMS TUESDAY...

.DISCUSSION...For the remainder of the night, expect light
downvalley winds in protected drainages, along with good humidity
recoveries. Gusty easterly winds will be possible along higher
exposed ridges later tonight, but mostly outside of the fire
perimeter.

Thunderstorms have remained well east of the area thus far, but
increasing moisture will move into the region overnight. As a
result, thunderstorm chances will be much improved tomorrow, with
widely scattered coverage expected. While lightning probabilities
will be higher, these storms will be generally slow moving from
the east, and are expected to produce measurable rainfall near
their cores. This should mitigate the dry lightning threat, but
not completely as lightning can strike outside of rain cores.
Expect very slight chances overnight tonight and early tomorrow
morning, with the greatest coverage expected mid afternoon and
evening tomorrow. Stronger storms will feature gusty and erratic
winds should they move close to the fire site, but winds otherwise
will be light and terrain driven. Temperatures will be hot again
tomorrow, but likely about 4 to 7 degrees cooler with slightly
improved humidity.

Thunderstorms will diminish slowly overnight, and humidity
recoveries are expected to be good. Light downvalley winds can be
expected as well.
