KEY MESSAGES

- Occasional rain and snow showers throughout most of the week

- Temperatures warm up until we get to the weekend

- Highs early next week struggle to get above freezing

SHORT TERM /THROUGH THANKSGIVING 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 /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1018 PM MST Mon Nov 24 2025

Strong winds and snow showers have ended as the cold front clears the region and modest ridging starts to build in. Expect low-impact VFR conditions tonight and Tuesday. Tuesday night, mid-level clouds will increase from the west as some moisture tries to spill over the ridge. No notable impacts are expected at least into the first half of Tuesday night...thickening clouds and at least some VCSH for mountain valley terminals may be needed near the end of or just beyond the current TAF period.
