.SHORT TERM /Through Wednesday Night/...
A weak disturbance embedded in southwest flow over the area and
monsoonal moisture will trigger scattered showers and
thunderstorms over far SE Oregon and southern ID this afternoon
and evening, generally from Burns OR, to the Owyhee Mountains
to the Magic Valley. Strong gusty outflow winds to 55 MPH may
accompany some storms. Storms will generally weaken into
showers as they move northeast into the Snake Basin, but gusty
outflows and blowing dust will still be a threat. Showers taper
off overnight. An upper level ridge axis will remain just east
of the area Tuesday and Wednesday while low pressure remains
situated off the Pacific Northwest. This will keep southwest
flow over the area with temperatures trending up slightly. A
weak wave will move over the region on Wednesday resulting in
an uptick in winds (mainly across SE Oregon) and a slight
chance of thunderstorms across the central ID mountains and from
the Magic Valley south to along the Nevada border.

&&

.LONG TERM /Thursday through Monday/... Hot temperatures will
persist Thursday, although a gradual cooling trend will continue
through the week. A weak shortwave Friday will begin the breakdown
of an upper-level ridge, and lead to a slight chance of
precipitation come Friday, mainly across the higher terrain of
southwest and central Idaho. Although as of now moisture looks
rather limited. Come Sunday, guidance is in good agreement of
another low coming down the British Columbia coast and swing past
past our area. This low, and associated cold front, will bring a
cool down and increased precipitation chances (most pronounced in
the central ID mountains). Temperatures on Sunday will likely swing
below normal following the cold frontal passage, with the lower
Snake Plain having a 40% chance of the afternoon high being below 80
degrees. Breezy conditions will persist throughout the long-term
period.
