• Not much change in the overall pattern: Relatively cool and west in the Northwest and Southeast. Warm and dry in the central U.S. Hot for Texas and New Mexico.
• Severe weather persists, but should be less intense this coming week.
• The tropics are starting to look like August rather than June.

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.
