Travel & RV Weather Extended Outlook updated p.m. Sunday 28 November 2021

Tuesday 30 November – Sunday 5 December

Extended outlooks are more general in nature than the daily short term forecasts. Beyond a week, there is often significant uncertainty in the location and intensity of specific weather events. I will note where there is less, or greater, confidence than normal in these extended outlooks.

For more information, check out the latest weather animations.

Here is the latest short term weather forecast.


  • Little change in the weather pattern over the next seven days (still).
    • Warmth in the West slowly displaces cooler temperatures in the East
    • Drier than average except for Washington State
  • Periodic high winds over the Northern Rockies.
  • No really cold air for the Lower 48 through at least mid-December.

Outlook for Tuesday 30 November – Thursday 2 December:

— Rains return to coastal and northern Washington State Tuesday and Tuesday night.

— Another clipper storm Wednesday and Thursday, but this storm will have more rain and less snow than the clipper from this past weekend.

Outlook for Friday – Sunday 3-5 December:
