• Slow moving upper air pattern leads to weather that changes little from day to day for any individual location.
• Coastal storm brings rain and wind to the Southeast and Mid-Atlantic for the first part of the holiday weekend.
• Daily chances of scattered severe thunderstorms through Monday.

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.
