.SHORT TERM /Through Tuesday Night/...
Issued 208 PM MDT SUN MAY 3 2026
A ridge of high pressure will build over the Western US and
British Columbia, bringing temperatures 10-15 degrees above
normal to the region through the short term period. A low
pressure system will move onshore over California today,
bringing a push of showers and thunderstorms near the Nevada
Border and over high terrain in Baker/Valley Counties. This low
will then migrate east, continuing the chance of afternoon
showers and thunderstorms (20-30% chance) to the areas near the
Nevada border on Monday and Tuesday. Very dry air near the
surface, shown in inverted-V forecast soundings, will limit
precipitation from these showers and thunderstorms. Wind and
lightning will therefore be the primary hazards, with outflow
gusts up to 40-50 mph from any of the strongest
showers/thunderstorms. These gusts will also bring patchy
blowing dust, especially near dry lake beds in Eastern Oregon.
Winds will increase on Tuesday with northerly flow strengthening
over the region. The highest winds will be seen in Eastern
Oregon with sustained northerly winds around 15-25 mph with
gusts up to 40 mph, with ridgetops seeing strong winds up to 45
mph.

.LONG TERM /Wednesday through Sunday/...
Issued 208 PM MDT SUN MAY 3 2026
The ridge of high pressure will continue to amplify over the
region through the work week, bringing mostly dry conditions
and above normal temperatures through Friday. A shortwave
passage over Montana-Wyoming late Wednesday into Thursday will
increase potential for mountain showers and thunderstorms in
southwest Idaho, but confidence is low (<10% chance). Another
shortwave will quickly move in from the west on Friday. This
will bring a slight reduction in temperatures (about 5 degrees
cooler) on Saturday, with a 10-30% chance of showers over high
terrain in southwest Idaho and southeast Oregon. High pressure
will then rebuild over the West on Sunday, bringing the
potential for Treasure Valley temperatures to reach the upper
80s and maybe even 90F (5-10% chance in Boise area).
