Area Forecast Discussion
National Weather Service Boise ID
316 AM MDT Fri Apr 11 2025

.SHORT TERM...Today through Sunday night...Cooler air starts to
infiltrate the area today due to the arrival of a cold front
currently situated in SE Oregon. The front will be slow to move
southeastward as an upper trough moves into the Pacific
Northwest. Dynamics associated with the trough along with
cooling aloft will increase the probability of showers from
about 15-30 percent later this afternoon to 30-60 percent
tonight. Initially, showers are expected to be situated from
near Burns to McCall, then settle into portions of SW Idaho as
the trough gets closer tonight. The bulk of the precipitation
is expected west and north of Boise. In addition to the
showers, the models continue to indicated enough instability to
warrant a slight chance (less than 20 percent) of thunderstorms
late this afternoon and evening. The hi-res models are not in
agreement, so confidence is low. Showers linger on Saturday as
the trough moves across the area, mainly in the West Central
Mountains where snow levels lower enough for light snow
accumulations of an inch or two above 6000 feet. Windy
conditions develop on Saturday, especially in s-central Idaho
(SE of Boise) where gusts to around 40 mph are expected by the
afternoon. Temperatures trend 5-15 degrees lower today and
another 5-15 degrees on Saturday. Cool but dry conditions return
on Sunday along with lighter winds.

.LONG TERM...Monday through Friday...Dry conditions prevail
through the week due to a high pressure ridge that develops on
Monday and generally lasts through the end of the week. The
only exception is an upper trough that moves through on Tuesday
or Wednesday that temporarily weakens the ridge. Moisture still
appears to be limited with the trough, but will likely be
accompanied by some clouds. Temperatures average 10 to 15
degrees above normal. The coolest day is expected to be on
Monday followed by a slight warming trend as highs approach 80F
in the lower valleys on Friday.

.AVIATION...VFR. Widespread high clouds and increasing mid
clouds today. Scattered showers develop after 18Z, generally
west of a KREO-KONO-KMYL line. Slight chance (less than 20
percent) of thunderstorms in Harney County after 21Z. Surface
winds: mainly W-NW 5-15 kt. Winds aloft at 10kft: SW 15-30 kt.

KBOI...VFR. Surface winds NW 5-10 kt.

Weekend Outlook...Mostly VFR. There is a 30-60 percent chance
of showers along a cold front tonight, decreasing on Saturday.
Slight chance (less than 20 percent) of thunderstorms this
evening. Areas of MVFR conditions and mountain obscuration in
the mountains early Saturday. Dry Sunday. W-NW surface winds
5-15 kt, except 15-25 kt with gusts 30-35 kt Saturday.
