.SHORT TERM /THROUGH THURSDAY NIGHT/...
Issued at 1222 AM MST Tue Nov 25 2025

While the weather remains unsettled through Thanksgiving Day,
minimal impacts are expected. We do see occasional rain and snow
showers, with most of the moisture falling in the central
mountains and eastern highlands. We might see a couple of
periods of those showers reaching down into the Pocatello area
and southeast highlands. The point is the precipitation amounts
will generally be light throughout. We might pick up a couple of
inches through tomorrow morning across the Sawtooths/surrounding
ranges and also across the Big Holes, Tetons, and higher
elevations around Island Park. Temperatures will be coolest, for
now, this afternoon with valley highs in the mid 30s to mid 40s.
By Thanksgiving afternoon, highs down low will be in the mid 40s
to mid 50s...with 30s and 40s in the backcountry.

.LONG TERM /FRIDAY THROUGH MONDAY/...
Issued at 1227 PM MST Mon Nov 24 2025

Things take a sharp turn colder as we look to head into the
weekend and early next week with models showing an upper level
trough swinging through the area over the weekend. Where they
disagree though is with respect to the depth of this colder air
intrusion just how much moisture, if any, will be present when
it occurs. That being said, confidence is increasing in a
significant cooldown for the weekend where high temps areawide
may struggle to get above the freezing mark. There is much less
confidence however when it comes to the precip side of the
forecast. As such, felt it best to continue to run with the NBM
which is a general broadbrushed approach to PoPs indicating at
least some chance for snow throughout the area, even in the
valleys, but confidence on the precip side of the forecast is
low. Bottom line, stay tuned - as it appears that our relatively
mild November is going to come to an abrupt end as we near the
last day or two of the month and push into December. Things on
the precip front can and likely will change over the next few
days.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
Issued at 1052 AM MST Tue Nov 25 2025

VFR conditions continue across the area this morning with just
some mid/high clouds streaking across the area for the time
being. Winds are light and will remain as such through the
period. The biggest changes will be the increase in cloud cover
as we move into the evening and especially the overnight hours.
BKN/OVC cloud cover and some precip is even possible,
especially around KSUN and KDIJ, during the current TAF cycle.
CIGs will likely stay at VFR levels around 4-5 kft but some
slightly lower ones are certainly possible at KSUN and KDIJ with
any precip. For now, added VCSH at KSUN and a period of -SN at
KDIJ. Can`t rule out some light snow showers at KIDA, KBYI and
KPIH but chances appear to be too low to include for the moment.
Expect BKN/OVC CIGs to linger into the first part of the day on
Thursday.
