KEY MESSAGES

- After record-breaking rainfall, high pressure returns with clearing skies during the afternoon. Dry conditions expected until possibly this weekend.

- Northerly airflow behind storm will bring chilly overnight lows starting tonight.

DISCUSSION

Issued at 134 AM MST Mon Nov 2 2026

Today through Wed night...The bulk of precipitation ends prior to forecast start at 0500 MST this morning. Some lingering showers over the highlands bordering WY should end during the afternoon. Clouds will clear for tonight and the main risk tonight will be BR/FG and stratus clouds.

Temperatures today will struggle into the upper 40s at lower elevations. The cool end to the afternoon means chilly temperatures under nearly clear skies: Teens in the alpine basins, mid-20s to low 30s for the Snake River plain/eastern Magic Valley, 20s for the highlands. The abundant sunshine will put both highs and lows on a warming trend for Tue. Cloud cover on Wed/Wed night will cool highs and level off overnight lows. The cloud cover comes from a low moving through UT.

Windy conditions this morning in the post-frontal zone will subside during the afternoon as the upper level support for strong wind diminishes.

Thu through Sun...Building upper level high pushes storm track farther north and away from southern ID. The ridge axis staying to the west will mean northwest air flow and a re-supply of cold air that will keep temperatures from warming too strongly, or even leveling off until Sun. On Sun, a low off the west coast shifts wind to more southerly and temperatures will warm more strongly.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 903 PM MST Sun Nov 1 2026

Rain is starting to pull away from the TAF sites. Low clouds will create a mix of IFR/MVFR ceilings overnight into tomorrow morning. Think winds will stay strong enough that fog will most likely not be an issue, but with as much rain that has fallen it is about a 20% possibility.

FIRE WEATHER

Issued at 134 AM MST Mon Nov 2 2026

Cold temperatures and high humidity will continue through at least Tue. High pressure will allow more significant lowering of humidity on Tue afternoon/Wed. Conditions should become dry after today with no precipitation expected until possibly late in the upcoming weekend. Stratus and fog will be affecting areas both tonight and Tue night. Gusty wind today in the Southern Idaho Dispatch area will decrease during the afternoon.
