KEY MESSAGES

- Building Weekend Ridge: Upper-level ridge will become established across the Intermountain West into early next week, supporting a prolonged period of dry and tranquil conditions. - Warmer Temperatures Coming: Temperatures will climb 5 to 10 degrees above seasonal averages Sunday into early next week, pushing lower-elevation highs toward 60F.

- Forecast Uncertainty Late Next Week: Model solutions currently differ regarding the upper-level pattern during the latter half of next week.

DISCUSSION

Issued at 1238 PM MST Sat Nov 7 2026

Satellite imagery shows East Idaho under ridge axis with weak shortwave departing to the east and strong closed low in the north Pacific. Most of East Idaho is clear but pockets of low clouds still linger in the northwest stretches of the Arco Desert towards the Divide. A series of shortwave features eject inland Sunday and again Monday night/Tuesday. The latter feature may have the best chance at producing a few light showers across northern zones, along with a drop of a few degrees in daytime highs by Tuesday. Otherwise high pressure remains in control with temperatures remaining above normal for much of the week. Looking ahead to the potential pattern chance late in the week or next weekend, deterministic models have trended toward development of a deep split flow pattern late in the week, delaying inland push of the northern stream trough. Precipitation now looks to hold off until Friday night or Saturday, though a few ensemble members introduce precipitation as early as Friday afternoon.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1004 AM MST Sat Nov 7 2026

Clouds are moving out of Eastern Idaho now and we will see mostly clear skies for the rest of the day and fairly light winds. VFR conditions continue through the rest of today and another round of clouds will pass through tonight and linger a bit longer into Sunday. At this point, NBM is only showing about a 10 percent chance of MVFR CIGs and VIS tonight at IDA and DIJ, so will hold off on adding anything into the TAFs for now.
