UPDATE

Updated aviation discussion.

KEY MESSAGES

- Slightly above normal temperatures through the week.

- A slight chance of showers north of Baker to McCall on Thursday.

- Above normal temperatures and dry over the weekend into early next week. Stagnant conditions in the lower valleys with temperature inversions possible.

SHORT TERM /Through Friday Night/

Issued 254 PM MST WED NOV 4 2026 A weak system will pass by to the north on Thursday bringing a slight chance of showers to the west central ID mountains, with increased clouds elsewhere. Otherwise, quiet conditions as a dirty ridge develops on Friday into the weekend with high clouds and slightly warmer temperatures.

LONG TERM /Saturday through Wednesday/

Issued 254 PM MST WED NOV 4 2026 The long-term period will feature a largely stagnant pattern of broad ridging over the central CONUS and a trough off of the Pacific Northwest coast. This pattern will keep our area dry with moisture pushed to the north and support temperatures up to 10 degrees above normal. Breezy winds will develop this weekend as a short-wave clips our area, although the only other tangible evidence will be increased cloud cover. Multi-run ensemble means hint at a return to unsettled conditions after mid-week next week; although there is still considerable uncertainty in the details.
