• Heat builds over the Desert Southwest and interior California; heat persists across the country along and south of I-40.
• Bands of rains over the central Plains, Mid-Mississippi Valley, Ohio Valley and the Northeast.
• Severe thunderstorms possible each day somewhere across the Plains to the Midwest and Northeast.

Extended outlooks are more general in nature and higher level 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.

Starting Monday morning, 27 November, this site will be down for a major upgrade. RVWeather.com will return no later than Wednesday 29 November — sooner if possible. When the site returns, WILMA, our NEW(!) integrated weather impacts product, will be available. The Paywall will also be implemented. RV Weather will continue to provide free access to essential, RV-relevant National Weather Service Warnings and Advisories, current weather, and weather safety information. While the main site is off-line, I will post a simple forecast to my email list and to RVWeather on Facebook.
