.SHORT TERM /Through Saturday Night/...
Issued 334 AM MDT THU MAR 26 2026
The cold front has pushed into eastern Idaho early this morning,
with gusty northwest winds in its wake. Gusts of 30 to 40 mph
will continue through mid-morning along the I-84 corridor
between Baker City and Ontario and areas east of Boise. Surface
and mid-level support for the wind will weaken through the day,
resulting in diminishing speeds this afternoon. It will remain
breezy east of Mtn Home with gust potential of 30 mph through
sunset. High temperatures will run 15-25 degrees cooler than
yesterday for most sites placing them around 5 degrees below
normal. This will set up a chilly night as light winds and
mostly clear skies allow for sub-freezing low temperatures
across the entire area Friday morning.

Heading into the weekend, temperatures are back on the rise,
responding to a zonal flow/low amplitude upper ridging.
Temperatures will return to around 10 degrees above normal by
Saturday which will put valleys into the low 70s. While dry,
the mostly westerly flow will supply plenty of moisture aloft,
so expect periods of mid-high clouds.

.LONG TERM /Sunday through Thursday/...
Issued 334 AM MDT THU MAR 26 2026
Upper-air flow will be southwesterly to begin the period, caused
by an incoming upper-level trough into the Pacific NW and the
upper- level ridge axis over the eastern Rockies/Great Plains.
Above-normal temperatures will linger in the area Sunday (10-20
degrees above) and Monday (10-15 degrees above) before a shift
to a much more unsettled pattern. By mid-to-late Monday, most
models agree on the upper-level trough axis moving onshore, with
continued upper-level shortwaves continuing to move onshore
through the extended. This will cause temperatures to be near-
normal, bring widespread precipitation chances (especially
Tuesday onwards), and return snow to the higher elevations.
Breezy to gusty winds will also stick around following the
initial cold front late Monday/early Tuesday. Significant
variance currently exists among the clusters, namely in the
intensity of these upper-level shortwave troughs. The intensity
will drive the extent of the intrusion of colder air, higher
precipitation chances, and the extent to which we stay in this
pattern. Regardless, a much-needed seasonable pattern shift is
on the horizon.
