Why do I have to login every time I visit Wunderground?

Our membership is designed to allow our members ad-free viewing for the entire year of service. As long as members do not hit the "Sign Out" link, they should be recognized the next time they visit our site.

If you find that you need to login every or most times you visit, then your cookies are most likely set to clear after each session, or very frequently. Please check your cookie settings in your browser's "Options" or "Internet Options". This can often be found in the browser's menu bar under "Tools", but every browser is a bit different.

*If you access our site through a prefix other than http://www.wunderground.com, it can cause cookie problems and you may not be recognized when you sign out.
