Anyone have any insight as to where services like DarkSky are getting their minutely (per minute) data? IE "Light rain in 33 min., ending 8 min. later"? I'm just curious as to the underpinnings of this. Based on their kickstarter page back when they were seeking funding, it appears to me that they are interpolating / morphing between the current weather radar and the next future predicted radar frame. Thus instead of the future radar jumping 30 minutes to an hour in the future, they interpolate into individual frames per minute. Voila - then you can get the chance of precipitation for any given point by looking it up in your maps.
I was just curious if anyone else had interest in this or knew the underlying processing. Also, does the NWS provide "future" radar? If not what kinds of sources provide that (as raw data)?
