.SHORT TERM...Tonight through Thursday night...Amplification of
an upper ridge over the Intermountain West will bring a stretch
of dry and warm weather to the region. Temperatures will be on
the rise through Thursday with highs ranging 5-10 degrees above
normal which will put lower elevations into the mid-80s. Winds
will remain light and terrain driven through the period. Expect
coverage of mtn valley fog to decrease with each passing day as
a drier air mass sets in over the area.
.LONG TERM...Friday through Tuesday...Clouds will increase on
Friday as an upper trough tracks along the NW US/Canadian
border as a second low pressure system along the central CA
coast lifts northward. These features will increase moisture
over the region late Fri/Sat, introducing a 10-15% chance of
afternoon showers/thunderstorms across SE Oregon and the along
ID/NV border. This threat shifts to the e-central Oregon and
w-central Idaho mtns on Sunday as an upper trough pushes in from
the coast. A period of brief ridging brings a break from any
precipitation early next week with a chance of rain returning
late Tuesday. Temperatures are above normal through the period.
