SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 1228 PM MST Tue Nov 25 2025

Minimal impacts expected through Wednesday night as we head into Thanksgiving morning. Will have a few upper level short waves pushing over upper lever ridge to west with some showers late tonight in the Sawtooths, Central mountains and Upper Snake Highlands with most likely amounts under 0.1 inches and the same occurs Wednesday night with very light precipiation amounts once again. Will be warmer tonight with increasing cloud cover with lows mainly teens mountains and 20s lower elevations. Highs Wednesday will be above normal once again with mid 30s to around 40 mountains and 40s to near 50 lower elevations. Lows Wednesday night in the 20s and 30s. Wind impacts not expected in the short term.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 1228 PM MST Tue Nov 25 2025

Not much has changed much in the extended portion of the compared to yesterday. Thanksgiving Day looks to be a rather mild day for eastern Idaho with temps expected to top out in the upper 40s to mid 50s for most locales. Slightly cooler of course in the higher elevations and around Island Park but still unusually mild for late November. Things start to change on Friday as upper level troughing digs into the area bringing some much colder air to the area for the weekend and into early next week. Friday temps will run around seasonal norms but things take a downward turn starting on Saturday. Models still having some disagreements on the depth and intrusion of the cold air and a large spread amongst various ensembles still remains. As such, still seeing a rather large spread within the NBM itself although things are slowly trending warmer over the last few runs. That being said, it will still be MUCH colder than what we've seen for much of the month of November with highs likely staying mostly in the 30s for much of eastern Idaho. Depending on how things play out with the models, these numbers could get nudged up or down over the days ahead given the continued uncertainty. On the precip front, things look to be trending a bit drier with this push of colder air as well. Nevertheless, still have at least some mention of PoPs for most of the region Saturday and Sunday with the better chances focused across the higher terrain in the eastern highlands but still not looking like any high impact snowfall at the present time. Again, this can still change this far out and some light snow at the valley floors is still possible over the weekend. Should have a bit more clarity on this by the time we get closer to Thanksgiving Day and some higher resolution model data becomes available. Stay tuned over the days ahead!

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 842 PM MST Tue Nov 25 2025

No major changes to the aviation forecast for the 06Z TAFs. VFR conditions continue tonight with increasing cloud cover heading to all terminals through most of Wednesday. Did remove the VCSH at KSUN for early tonight, but kept it beginning around 10Z, though confidence there remains low and showers may stay a bit farther north and west of the terminal, but will watch that tonight. Chance of showers at KPIH and KIDA is closer to 10-20 percent, so will hold off on any VCSH or -SN in the TAF for now. That said, would not be surprised to see a few flurries at KIDA early in the morning. KBYI is expected to remain dry and the best chance for light snow will be at KDIJ where MVFR CIGs and VIS are in the forecast starting around 11Z early Wednesday morning.
