167 FXUS65 KPIH 251958 AFDPIH Area Forecast Discussion National Weather Service Pocatello ID 1258 PM MST Tue Nov 25 2025 .KEY MESSAGES... - Occasional mainly mountain rain and snow showers throughout most of the week - Extremely mild temperatures Wednesday through Friday - Significantly colder temperatures over the weekend through early next week && .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 MONDAY/... 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 /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. && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...GK LONG TERM...McKaughan AVIATION...McKaughan
