KEY MESSAGES

- Occasional mainly mountain rain and snow showers continue

- Above average temperatures through Friday

- Significantly colder temperatures over the weekend through early next week

SHORT TERM /THROUGH FRIDAY NIGHT/

Issued at 100 AM MST Thu Nov 27 2025

Our abnormally warm pattern will remain in place for the next 36-48 hours. Some light precipitation will shift north and east across our area through early Friday, with little to no impact for us. We will see a quick hitter drop southeast tomorrow and tomorrow night, bringing a shot of rain and snow to central and eastern Idaho. With this low coming in from the northwest, this will help produce a slightly better chance of moisture for the Snake Plain and bench areas...and also finally kick off rain and snow for the southeast corner. Snow levels will peak at 5500-6500ft ahead of the push of colder air. If we get some heavier precipitation to fall during this period, it is possible snow levels drop another 500-1000ft...even if it not going to accumulate. Little precipitation, if any, falls tomorrow with this storm at lower elevations. Most mountain ranges will see around 0.10" or less, although portions of the eastern highlands could see 0.10-0.30". There is a 10-40% chance of exceeding that threshold during that 24 hour period. That equates to 1-4" of highest elevation snow, with under 1" possible in the valleys. Winds do pick up with this low passing through, but nothing widespread and of significance it appears right now. Temperatures remain on the mild side, but today will be the warmest with valley temperatures hitting the mid 40s to mid 50s for highs. Tomorrow remains ABOVE AVERAGE, but barely and will be down 5-10 degrees from today.

LONG TERM /SATURDAY THROUGH WEDNESDAY/

Issued at 128 PM MST Wed Nov 26 2025

This system for Friday and Friday night 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 /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 845 PM MST Wed Nov 26 2025

Northwest flow aloft continues tonight through tomorrow with more mountain snow showers in the forecast. Will continue with VCSH in the TAF for SUN as we continue to see radar returns out there tonight, though are hard pressed to confirm anything making it to the ground. Overall, dry conditions are expected at BYI, PIH, and IDA, but the clouds moving into BYI and PIH are lowering CIGs just a bit more than originally anticipated. Still VFR, but closer to borderline VFR/MVFR. 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 most 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 around 11Z to 16Z Thursday morning.

PIH WATCHES/WARNINGS/ADVISORIES

None.
