Travel & RV Weather Extended Outlook updated p.m. Sunday 5 December 2021

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.
