KEY MESSAGES
- Building Weekend Ridge: Upper-level ridge will become established across the Intermountain West today through early next week, supporting a prolonged period of dry and tranquil conditions. - Warmer Temperatures By Weekend: Temperatures will run near normal again today before climbing 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 227 AM MST Fri Nov 6 2026
A ridge of high pressure will build over the region beginning today, which will keep conditions mild well into next week. Daytime temperatures will run within a few degrees of normal again today with widespread highs ranging the 40s. Southwest flow will help warm temperatures by more than 5 degrees on Sunday and temperatures will continue to run 5 to 10 degrees above climatological norms through much of next week, ranging the 50s to low 60s for much of Southeast Idaho. Models feature a couple of weak disturbances that will flatten the ridge early next week, although impacts look to be minimal with only slight chances for showers across the extreme northern extent of the CWA Monday evening. 500mb ensemble clusters indicate uncertainty regarding the upper-level pattern come late next week/weekend with some solutions introducing a trough late week while others maintain the ridge through late weekend.
AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
Issued at 441 AM MST Fri Nov 6 2026
Main threat this forecast package is the IFR CIGs and/or VIS at KIDA and KDIJ in low stratus and fog. Area observations indicate impacts are fairly localized and therefore would not be surprised to see conditions at these terminals continue to fluctuate between IFR and MVFR/VFR for the next few hours. Otherwise, winds will be light and variable today with mostly clear skies until SCT high clouds return this evening.
