Here's the link to the official FAA weather camera site:

Interesting story how this system came to be. A fellow named Jim Buckingham, who is a US Army LtCol and pilot, needed a PhD project. He came to a few Alaska aviation safety outfits, and proposed to install three weather cameras, and put the images up on the internet, if he could find some $$.
Long story short, he managed a $50,000 grant from NSF, and got air taxi operators to provide free transportation of the cameras, etc to remote villages.
With that money, he bought, transported and installed three sets of weather cameras in three villages in interior Alaska for three years.
The FAA didn't see much promise in the concept, but Senator Ted Stevens certainly did, and arranged to have a supplemental tucked in the FAA Alaska Region's budget. The FAA drug their feet on this, until they realized it would be pretty ugly to explain to Stevens why they didn't spend that money and it went back to the general fund. So, the FAA reluctantly started installing weather cameras around the state.
Long story short, I doubt that the FAA has had a single project that met with such universal approval by pilots. Funding continued to expand, and cameras and capabilities did as well.
A fellow named Kimo Vallar has run that program for a number of years, and has done a great job, turning feedback from pilots into results.
It is a VERY interesting project, and has been very successful to date. One of the reasons it became so successful is that these units are relatively cheap (like one fifth the cost of an AWOS) and with the advent of automated weather observers, the reliability of weather reports declined. Pilots trust the cameras more than the ASOS/AWOS in many cases.
Great system, and there are many many cameras with online feeds throughout Canada and the US, often directed at traffic reporting, but equally useful to pilots.
