.SHORT TERM...Today through Tuesday...Clouds increase today,
especially across east-central Oregon and west-central Idaho in
advance of an upper ridge. Highest peaks in Baker county and the
west-central Idaho mountains could see a sprinkle this afternoon
into tonight, but otherwise conditions remain dry and mild for
today. Skies clear from the west on Tuesday as the upper ridge
continues to build into the region. High temperatures warm to
within a few degrees of normal on Tuesday.

.LONG TERM...Tuesday night through Sunday...Temperatures will be
near normal Tuesday night and Wednesday, then slightly above normal
on Thursday under an upper level ridge. Models show an upper level
trough from the Gulf of Alaska moving over the Pacific Northwest and
western Canada on Friday. Based on current timing, our area will
still be ahead of the cold front on Friday, so temperatures will
remain warm. On Saturday models bring the trough across the northern
Intermountain Region, lowering temperatures by 5 to 10 degrees.
Coverage and amount of precipitation are still uncertain, but the
best chance will be over our northern zones. An upper level ridge
will follow the trough on Sunday, with dry weather and near normal
temperatures.

&&

.AVIATION...VFR. Moisture in northerly flow aloft will bring
increasing high and mid level clouds today. Surface winds will be
variable, mainly less than 10 kts. Winds aloft at 10k feet MSL will
be north at 10-20 kts.
