Long-haul truckers can now get hourly forecasts of road surface conditions and temperatures for every mile of major highway in the US, Europe, and parts of China. Autonomous vehicles—once they get rolling—will likely use the same kind of data to help them avoid slippery spots and storms on their way to deliver people and goods.

This valuable information may be coming not from the US National Oceanic and Atmospheric Administration and its vaunted weather agency, or even its European counterpart. Instead, companies may increasingly be paying for access to private data, trend analyses and forecasts, as part of the expansion of a new weather industry that is exploiting modern tools such as machine learning, automated sensing, internet-connected devices, and cloud computing.
