Google's WeatherNext 3 upgrades weather forecasting with real-time satellites

Google is rolling out WeatherNext 3, an AI weather model that uses real-time satellite data to deliver hourly forecasts with five-kilometer resolution—five times sharper than WeatherNext 2—and improved rain/snow predictions, especially where ground gauges are sparse. It can forecast hourly weather and wind for renewables, integrates with Search, Maps, and Gemini, and remains powered by physics-based data and agency collaboration. Google says precipitation forecasts a day out can be up to 50% more accurate in some regions.
