Official National Weather Service forecast for any US coordinate - six 12-hour day/night periods by default, or hourly - each with temperature in C and F, precipitation probability, a wind speed range in km/h, wind direction and a short forecast, plus the NWS issue time so an agent can judge its age. detail=full adds the narrative, icon, dewpoint and humidity. United States, its territories and coastal waters only. Use when: What is the weather forecast for these US coordinates?
