.SHORT TERM...Tonight through Saturday night...Dry 
northwesterly flow will persist through the weekend, maintaining
generally quiet weather across the region. Winds will remain 
light, with occasional afternoon gusts up to 25 mph in the lower
valleys. Skies will stay mostly clear, though localized areas 
of smoke are possible due to new wildfire activity. A few 
additional fires have been detected on satellite today, and its
likely that a few more will be seen this afternoon and evening.
At this time, smoke impacts appear minimal.

The northwesterly flow aloft should continue to steer smoke from
larger fires in south-central Oregon away from the area.
Temperatures will trend warmer through the weekendstarting near
seasonal averages on Friday and rising to about 5 degrees above
normal by Sunday.

.LONG TERM...Sunday through Thursday...Hot, dry, and breezy 
conditions are expected Sunday and Monday as strong high pressure 
dominates the southwest U.S. and influences the Intermountain West. 
A weak shortwave trough will approach from Canada late Monday and 
move south-southeast along the Northern Rockies by Tuesday. While 
the main bulk of mid-level moisture will remain east of the forecast 
area, latest guidance supports a 10-15% chance of thunderstorms 
farther west into central Idaho Tuesday afternoon and evening than 
previously expected. Surface winds will also increase with the 
trough passage and associated cold front, with gusts peaking around 
late afternoon. Max temperatures will lower slightly from Monday but 
are expected to remain a few degrees above normal. Thereafter, hot 
and mostly dry conditions are expected to return behind the trough. 
Models become somewhat disorganized toward the end of the week, but 
hint at the potential for showers/thunderstorms returning as 
southwest flow develops aloft.
