.SHORT TERM...Tonight through Thursday night...A weak north
Pacific upper trough will bring about 5 degrees cooling Wednesday
as it moves inland north of our CWA. Thursday looks as hot as
today as a short wave upper ridge comes inland ahead of a deep
upper trough from the Gulf of Alaska. Generally clear skies
until Thursday when clouds begin in southern zones. Models
develop enough instability near the ID/NV/UT tri-point for
a 10-20 percent chance of high-based thunderstorms Thursday
evening. Tonight and Wednesday night will be seasonably cool
with dry air and clear skies. No significant smoke indicated by
HRRR model. Thursday night looks several degrees warmer with
cloud cover and higher dew points. Winds will be light except in
southern Harney and Malheur Counties Thursday afternoon/night,
when west winds blow 15 to 25 mph with gusts to 30 mph.

.LONG TERM...Friday through Tuesday...A deep upper trough from
the Gulf of Alaska will come inland and through our CWA Friday
through Tuesday with much cooler air. Initial surface cold front
will pass through Friday. Pre-frontal gusty southwest winds will
shift to west/northwest 10-20 mph. High temps Friday will be in
the upper 70s through 80s. A second cold front will increase
northwest winds to 15-25 mph with afternoon gusts 25 to 35 mph
Saturday in open terrain. Highs Saturday will lower to the mid
60s to mid 70s, then mainly 60s Sunday and Monday, with breezy
northwest winds continuing. Models keep pcpn generally north
of our CWA with the best chance (20-40 percent) Sunday night
in the central Idaho mountains. Model consistency breaks down
Monday with ECM bringing the main trough axis through our CWA
while GFS leaves it off the northwest coast. Consensus for now
is with the ECM for continued cool, breezy weather Tuesday.
