ChronoWeather

ChronoWeather answers the question every driver asks before a long trip: what's the weather going to be like when I get there? Not at your destination right now — at every point along your route, at the exact time you'll be driving through it. Leave San Francisco at 4 PM and ChronoWeather shows you: clear skies through the Central Valley at 6 PM, a rain band near Coalinga at 8 PM, and a dry arrival into Los Angeles by midnight. Not just a forecast — a forecast aligned to your drive. HOW IT WORKS Enter an origin, destination, and departure time. ChronoWeather samples points along your route and fetches the weather forecast for each one at the moment you'll be there.
