.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 128 PM MST Wed Nov 26 2025

Afternoon satellite imagery shows continued low to mid level
clouds streaming across eastern Idaho today but some occasional
breaks in the cloud deck have been observed in recent hours. As
such, temperatures are starting to warm into the 40s and even
near 50 as you head into the Magic Valley and parts of the lower
Snake Plain where we`re starting to see a bit more sun. Areas
without, remain chilly, generally in the 30s for the moment. As
we progress through the rest of the day, weak upper level
ridging will start to build over the area as we move into
Thanksgiving Day. Will still have some lingering moisture in
place across the central mountains and eastern highlands this
evening and another round of light snow showers will be possible
during the next 12-18 hours. The aforementioned ridge will
bring some very mild temps to the region for the holiday
tomorrow along with a little bit more sunshine compared to
today; but we`ll still have some clouds in place however,
especially across the upper Snake Highlands, eastern highlands
and up towards the Island Park area. Highs tomorrow should top
out in the upper 40s to mid 50s across the lower elevations
which is quite mild for late November. Areas that see a bit more
clouds likely stay in the low to mid 40s for much of the day
however. Precip should be limited for Thanksgiving tomorrow with
only some isolated shower chances possible across the eastern
highlands in the mid/late morning hours but for the most part,
it`ll be a dry holiday. Any precip that does fall will be light
and generally of little impact to holiday travel.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 128 PM MST Wed Nov 26 2025

Series of shortwaves impacts East Idaho through the extended
period. The first arrives during the day Friday, producing
light snow across higher elevations and breezy winds through
portions of the Snake Plain. This system exits quickly, but is
followed by the second feature arriving late Saturday. Light
snow may be possible down to some valley floors Saturday night.
Accumulations should remain light, even at higher elevations for
both systems. The story, though, is the cooler air expected to
filter into the region beginning Sunday as the system sags
through the region. 35% of the ensemble members are sharper and
colder with the trough on Sunday into Monday, while all clusters
agree on general timing of the feature. NBM probabilistic
spread on temperatures does not seem as drastic as it was
earlier this week, though the deterministic temp is still
running at the high end of the spread, so there is likely some
wiggle room for lower temperatures to come early next week.
Third system of the extended period arrives Tuesday for another
round of precipitation into midweek.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 429 PM MST Wed Nov 26 2025

Northwest flow aloft continues this evening through tomorrow with
more mountain snow showers in the forecast. Will continue with VCSH
in the TAF for SUN as there are a few radar returns around it
already with more moving in for tonight. If we can get some light
snow to actually materialize, there`s about a 10 percent chance
for MVFR conditions at SUN. Overall, dry conditions are
expected at BYI, PIH, and IDA. There`s another small (around 10
percent) chance for a few flurries at IDA and PIH again early
Thursday morning just like we saw this morning, but little to no
impacts are expected. We are more likely to see impacts at DIJ
where there is closer to a 40 percent chance for snow showers.
IFR conditions are in the TAF for DIJ with low VIS and CIGs as
snow showers pass through with the most likely timeframe being
from 11Z to 17Z Thursday morning.
