Tempescope is connected to weather forecasts and online weather programs, which means you can use it to see what the weather will be like tomorrow. But unfortunately it cannot create snow.
The invention is not new, it got some attention back in 2013, but the interesting thing is that a 2015 crowdfunding campaign is underway.
If you want to build your own Tempescope, you will find the necessary material here, as open source code.
