This site is free (to you), but I've lost money every year since I started in 2007. By requiring login, there's a better chance you're a real person and you won't abuse this serivce, which is kinda the point.
I don't sell, trade, or expose your email (IP address, history, ...). My mail server is too small to spam you and I'm too cheap to upgrade. See links to Privacy Policy and Conditions of Use, in the upper right of this page for details.

About
I started this site in 2007 because I was terrified of fog obscuring my home airport (KOAK) while I was out training. Gathering and interpreting all the largely textual weather reports made seeing the "big picture" tough.
Since then, thousands of pilots, controllers, and dispatchers have used this site to aid their flight planning. Nearly 8,000,000 searches have been performed; twenty-two thousand detailed weather briefs have been generated.
