No one in the foreseeable future is going to use cellphones as parallel processors. First of all, the communication latencies are way too large to coordinate anything usefully. Second of all, users are already upset about the lack of battery life available for their phones.

It's not exactly parallel processing, but the Dark Sky app already does its forecasting calculations on the iPhone: http://jackadam.github.io/2011/how-dark-sky-works/
> The reason we encode velocity data as an image is so we can pass it off to the GPU on the iPhone and iPad. Both the storm prediction and the smooth animations are calculated on the device itself, rather than the server, and all the magic happens directly on the GPU.

In case anyone starts wondering, in the article it says that they're assuming that atmospheric motion is linear, which they justify (reasonably) because they're only looking over short time scales. So, although it is a forecast, it's a pretty simple one ;-).
