.DISCUSSION...Drier and warmer conditions will continue at the
burn site today. A storm system will develop into Arizona this
evening and lift northeast tomorrow into Thursday, spreading
moisture into the area. Showery precipitation and a few
thunderstorms will be possible at the burn site, with snow levels
10000ft or higher as the airmass remains on the mild side.
Otherwise, the pressure gradient will remain northeasterly through
tonight, and as such, overnight downcanyon winds may be enhanced.

The airmass will dry out again beginning Thursday night.
Southwesterly winds will then increase Saturday into Sunday ahead
of the next storm system which will push a dry cold front through
the burn site late Sunday afternoon.
