.DISCUSSION...
Issued at 134 PM MDT Sat Apr 11 2026

Showers and thunderstorms are moving through the area today as
moisture continues to be pushed our way by the low moving inland
towards northern California today. SPC has a good portion of our CWA
included in the Marginal risk for severe storms today. Main threat
will be strong wind gusts to 60 mph  and small hail with storms.
We`ve already seen a few storms in the southeast corner produce
gusts around 50 to 55 mph. Gusts outside of storms today will be
closer to 20 to 30 mph through the Snake River Plain and Eastern
Highlands. It will be quite breezy on Sunday, outside of
thunderstorm activity, especially in parts of the Snake River Plain,
South Hills and Eastern Highlands with gusts again around 30 to 40
mph, though wouldn`t be surprised to see some gusts closer to 45
mph. We will be brushing right up against WIND ADVISORY criteria
with about a 30-40 percent chance of maximum gusts reaching 50 mph
in these areas tomorrow. Our aforementioned low will be over
northern CA on Sunday and working eastward, bringing these gusty
winds and more showers and thunderstorms on Sunday. Snow levels will
fall to near 7500 feet by Sunday morning. Highs on Sunday will again
be in the upper 50s to low 60s before we cool down for most of the
week ahead. Between showers and storms today through Monday, models
are showing about a tenth to a quarter inch of liquid precipitation
in the eastern Magic Valley and Snake River Plain. In the mid to
upper elevations, those totals will be closer to a quarter to a half
inch with a few spots closer to three quarters of an inch, though
that will be more likely for spots that have thunderstorms pass
directly overhead. Snow levels will continue to fall and be near
5000-5500 ft by Monday morning as the low moves over Eastern Idaho
and transitions into more of a deep trough than a closed low.
Mountain snow is still in the forecast, though it has decreased
slightly for the Eastern Highlands and increased slightly for the
Central Mountains. Most of it will fall at and above pass levels
with 3-5 inches total from Sunday morning to Monday morning around
Galena Summit and 1-3 inches near Emigration Summit.

By Tuesday, a few showers will linger in the Eastern Highlands as
the trough continues to march eastward into Wyoming and highs will
be in the mid 50s for Tuesday and Wednesday afternoons. Look for
increasing winds on Wednesday ahead of our next low and cold front
dropping in from British Columbia. Gusts in the upper Snake River
Plain already look to be in the 35 to 45 mph range, so will likely
need a WIND ADVISORY for Wednesday, but we will see how that evolves
over the next several days. This system will bring yet more
precipitation for the area and another drop in temperatures for
Thursday and Friday.

also highly variable, currently with gusts peaking around 25kts

destabilize this afternoon with ISOLD to SCT TSRA, with gust
potential around or slightly exceeding 50kts. Maintained PROB30
