Thanks for running pressureNET! Whenever we show some data analysis, you can bet it will be on our blog at http://cumulonimbus.ca. However, you'll note that there's not much there so far. For the majority of the life of the project, we haven't had enough data to do anything interesting with it. Now, however, especially with Sandy (we gained 1,400 users yesterday alone), our data will be of immense value. We're working with a couple of researchers at universities (U Washington, and McGill) to best use and analyze the data. The answer to your question, though, is:

You can see our data by purchasing our weather prediction app that we'll build at YC this Winter. ;)

[Side note: we also plan on building a web version with a nice HTTPS API so that you can access the backend yourself. However, there are severe privacy issues to solve first and we're still working on that. Sorry about the delay, but until we find funding, pressureNET is a free-time-only project that moves a bit slowly]

[Edit: For pressureNET contributors like yourself, by the way, I plan on giving the predictions away for free. Anyone who does not/cannot contribute would have to buy the app. Or something like that]
