KEY MESSAGES

- Warming trend develops today, continuing through next Saturday, with little precipitation in sight, sticking to mountain and highland areas.

- Rebuilding ridge of high pressure could provide renewed bouts of low clouds and fog at times this coming week. Confidence in this is low though.

SHORT TERM /THROUGH TUESDAY/

Issued at 142 PM MST Mon Jan 26 2026

Afternoon satellite imagery shows ample sunshine across eastern Idaho this afternoon although this will quickly change over the next few hours. To our west, a weak shortwave is pushing across eastern Oregon and western Idaho and this will move across our area during the evening and overnight hours into Tuesday. Increased cloud cover is really the only noticeable impact although can't rule out some a very isolated snow shower/flurry. Chances are likely 10 percent, or less, so opted to not include any mention in the forecast as it shouldn't be anything impactful if it does transpire. Should already be seeing some clearing as we get into the daylight hours tomorrow as high pressure again will be building over the area. This should lead to temps near or just above normal for much of the region tomorrow. NBM continues to struggle with temps in the Stanley Basin so nudged those down significantly but everywhere else seems pretty reasonable as long as we can avoid any unforeseen stratus issues in the SNake Plain and Magic Valley. In short, it should be generally uneventful for the next 36 hours.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/

Issued at 142 PM MST Mon Jan 26 2026

Mainly quiet trend continues into the extended portion of the forecast with Wednesday likely be the most "active" day for weather across the area. Another weak system will swing through the region bringing at least a slight chance for some snow showers/flurries to parts of eastern Idaho. PoPs are mainly limited to the higher terrain of the central mountains and eastern highlands but any precip that is realized, shouldn't be too impactful as this system is not accompanied with much in the way of moisture. Most lower valleys are expected to remain dry although a stray flurry or shower is certainly possible. As we move into Thursday and the weekend, high pressure will continue to keep the region mostly dry and temperatures trending on the warm side of seasonal norms. A few weak impulses moving through the upper flow could spark some isolated PoPs across some higher elevation spots on Friday and again Saturday but again, not expecting anything of significance in regards to QPF and accumulation. If we can avoid any return of lower valley stratus under the influence of high pressure and light winds, we should climb into the mid and upper 40s for valley locations as we move towards this upcoming weekend and into early next week. Overall, quiet weather remains in place as we move into February with this unusually quiet winter continuing throughout the region.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1030 PM MST Mon Jan 26 2026

Weak high pressure and northwest flow aloft will continue to dominate over the next 24 to 36 hours, supporting few to no impacts to aviation across southeast Idaho. Weak disturbances/shortwaves will support mid- to high-level clouds at times and perhaps a very isolated snow shower (potential far too low to mention even VCSH in any of the TAFs), but significant winds, lower clouds, or fog/low stratus are not expected through Wednesday morning.

PIH WATCHES/WARNINGS/ADVISORIES

None.
