.KEY MESSAGES...

  conditions early this week.

- Slightly cooler temperatures and chances for precipitation
  return for the middle to end of the week.

&&

.SHORT TERM /Through Tuesday Night/...
Issued 340 AM MDT SUN APR 5 2026
High pressure will keep conditions dry with above normal
temperatures through Tuesday. The upper level ridge axis will
move overhead today, allowing high temperatures to increase
4-8 degrees from Saturday. Lower valleys will reach the lower
70s this afternoon. Otherwise, light easterly winds will develop
this afternoon with high clouds moving overhead. Temperatures
will warm a few more degrees on Monday as the ridge remains in
place. A slight chance of showers will develop late Monday
across eastern Oregon and the west-central Idaho mountains as a
weak system approaches the area. On Tuesday, an upper level
trough will move into the Pacific Northwest from the north. This
system will bring breezy to gusty winds in the afternoon,
especially across higher elevations where gusts will reach 25-40
mph. A cold front will move through late in the day, cooling
high temperatures by around 5-10 degrees across the north, but
arriving too late for cooling across southern areas.

&&

.LONG TERM /Wednesday through Sunday/...
Issued 340 AM MDT SUN APR 5 2026
Slightly cooler and more unsettled conditions return in the
extended period. The trough to our north will exit to the east
on Wednesday, with continued breezy conditions and 5-10 degrees
of cooling from Tuesday. Moisture ahead of a closed low near
the California coast will bring a 20-40% chance of showers to
southern areas on Wednesday. This low will slowly move onshore
to our south through the end of the week. This will bring a
10-40% chance of showers Thursday and Friday, highest along the
Nevada border and in the central Idaho mountains. Mild southerly
flow ahead of the low will bring another warming trend, with
lower valley high temperatures forecast to approach 70 degrees
by Friday and Saturday. Precipitation chances increase to 30-50%
across the area Saturday and Sunday as the low moves inland.
Ensembles favor a reinforcing trough moving into the Pacific
Northwest on Sunday with unsettled conditions likely to
continue. Precipitation will primarily fall as rain through the
period with snow levels above 6-8kft MSL.
