RV Weather Enterprises

• Heat migrates from the West to the Central U.S. and then to the Northeast by the latter part of the week.
• Drier week than normal, but some heavier rains possible by the end of the week around the southern Great Lakes region.
• Cooler than normal this week for the Pacific Northwest; cooler than normal next week for New England.

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.
