KEY MESSAGES

- Dry weather continues into next week

- Inversion conditions persist with limited fog/stratus

- Overall slow warming trend throughout this week

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 1151 AM MST Mon Jan 12 2026

We are seeing high and mid level clouds streaming across our area, but that is the extent of any "moisture" in our area. Expect this trend to continue as the ridge remains in place. Inversions are present BUT not as strong as they could be in the ridge was firmly overhead. It will slide a bit farther north and east, but still isn't expected to be centered over us. We did have to tweak temperatures down in some valleys based on trends. Where inversions hold a bit, highs will be in the 20s and 30s. Within the inversion layer or where we can get a bit more mixing to happen, temperatures will push higher into the 30s and even 40s. We've have limited fog and low clouds, mainly around Bear Lake and the Stanley Basin on any type of "widespread" basis. We did keep that in the forecast through midweek, and will keep tweaking it based on any developing trends.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 1151 AM MST Mon Jan 12 2026

There is still no potential for precipitation through the weekend, and this even extends into next week. We do see the ridge shifting west a bit by the end of this week, which may kick up the wind a bit and also turn the pattern more northerly or north-northwest over the state. The current Blend of Models doesn't really show any prolonged trend DOWNWARD, and maintains temperatures slowly warming up. The concern there is until we get inversions to truly break, it may be too aggressive with warmer temperatures. With the flow also turning more northerly again, the Blend may not be capturing any type of cooldown very well at all. We may need to make adjustments to temperatures in the coming days.

AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/

Issued at 429 PM MST Mon Jan 12 2026

VFR conditions likely to prevail through the period with light winds and precip free conditions expected to continue across eastern Idaho. Will likely see some mid/high level clouds streaking across the region at times but should be of little impact.
