Travel and RV Weather Extended Outlook through Thursday 27 July

  • Persistent upper level high pressure over the Four-Corners region locks in another week of the heat wave for Texas and parts of the West.
  • A drier week ahead, with fewer severe thunderstorms and flooding rain events.
  • Where to go? New England and the Pacific Northwest should have pleasant temperatures for most of this period.

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.

Tropical Outlook:

  • Tropical Storm Don continues its meandering over the central Atlantic Ocean. No impacts to the U.S.
  • Slight (20%) chance a new storm may form in the tropical central Atlantic this weekend or early next week. Far too soon to tell if there will be any impacts to the U.s.

Outlook into early August (a 2-4 week outlook is by definition low confidence!):

  • Drier than normal south of I-70 and east of I-25.
  • Rains possibly return to New England after the 5th of August.
  • Cooler than normal over New England.
  • Warmer than normal for the remainder of the country except California and the Pacific Northwest, where temperatures will be near normal.
  • It appears that most of the country will be warmer than normal through Labor Day.
