.DISCUSSION...Tonight and Tuesday...
Sunny conditions with milder temperatures and light winds will
prevail through Tuesday. Smoke dispersal will be generally Poor
outside of a few foothills locations.
LONG TERM DISCUSSION...Tuesday night through Saturday...
For the lower elevations, dry and unseasonably mild conditions
will continue through the weekend. The mountains will also be
dry and mild Wednesday, before a weak system brings light snow
accumulations to the higher elevations Thursday afternoon into Friday.
The Park Range may see a few inches of snow, with accumulations
being more uncertain elsewhere. West winds will strengthen moderately
for the high country and foothills Friday onwards. Smoke dispersal
conditions should see a gradual improvement through the week and into
the weekend.
...Thunderstorms imply strong gusty erratic winds...
