901 PM MDT Wed Apr 2 2025

.DISCUSSION...Showers were winding down this evening with just a
few lingering showers, but will redevelop over the high
terrain Thursday afternoon due to a large upper trough over the
interior west. There is also a slight chance (< 20 percent) of
afternoon thunderstorms in central Idaho. Temperatures may be a
degree or two warmer, but still several degrees below normal. No
updates.

&&

.AVIATION...Mainly VFR. Scattered showers after 03/18Z will
create periods of MVFR/IFR, mainly over the West Central ID Mtns
and near the NV border. Showers will be capable of graupel,
isolated lightning, and outflow winds up to 30 kt. Snow levels
3500-4500 feet MSL. Patchy valley stratus/fog through Thursday
morning will create periods of IFR/LIFR, mainly around KMYL,
KTWF, and KJER. Mountains obscured at times. Surface winds: W-NW
5-15 kt with gusts around 25 kt. Winds aloft at 10kft: N-NW
10-20 kt.

KBOI...Generally VFR. Scattered showers developing Thursday
afternoon over Boise foothills. Mountains obscured in
precipitation. Surface winds: NW 8-14 kt with gusts around 20 kt
by this afternoon.

&&

.PREV DISCUSSION...
SHORT TERM...Tonight through Friday night...The weather will
remain cool and unsettled through Thursday under an elongating
trough. Shower development will initiate off higher terrain
Thursday afternoon, fed by daytime instability. Similar to
recent days, lower elevations will see shallow cumulus buildups
with any low threat of precipitation (<10%) coming from
activity exiting the mtns on northerly flow. An upper ridge
builds in from the coast on Friday bringing dry conditions to
the region. Temperatures warm from around 5 degrees below normal
Thursday, to around normal on Friday. Winds will remain gusty
on Thursday, mostly along the I-84 corridor, relaxing some on
Friday as the flow aloft weakens.

LONG TERM...Saturday through Wednesday...A deep upper level
ridge will build over the Western US, bringing warm, above
normal temperatures, and dry conditions through Monday morning.
Highs will be around 3-5 degrees above normal, with overnight
lows still in the 30s in the valleys through the weekend. A
shortwave trough will move in on Monday afternoon, bringing
widespread showers and cooler temperatures on Tuesday. Snow
levels will drop to around 5000-6000 feet on Tuesday, with
minimal accumulations anticipated. A ridge will then quickly
build back in on Wednesday, bringing another push of warm and
dry weather with highs in the Treasure Valley approaching near
70 by Wednesday. This might be the end of the overnight frosts
in the valley for the time being, with long range models
favoring above normal temperatures through the month.

 &&

AVIATION...Mainly VFR. Scattered showers after 02/17Z will
create periods of MVFR/IFR, mainly over the West Central ID
Mtns and near KBKE-KBNO and the NV border. Showers will be
capable of graupel, isolated lightning, and outflow winds up to
30 kt. Snow levels 3500- 4500 feet MSL. Patchy morning valley
fog tomorrow will create periods of LIFR/IFR, mainly around
KMYL. Mountains obscured at times. Surface winds: W-NW 5-15 kt
with gusts around 25 kt. Winds aloft at 10kft: N-NW 10-20 kt.

KBOI...Generally VFR. Scattered showers developing this
afternoon over Boise foothills. A 10% chance of MVFR
rain/graupel showers hitting KBOI terminal this evening.
