Weather forecast by city: current weather and hourly forecast for any city or coordinates
Weather forecast by city name or coordinates: current temperature, conditions, precipitation, wind, humidity, cloud cover and pressure, plus an hourly forecast up to 48 hours ahead, for any city on Earth (MET Norway data). Give a city such as London or Tokyo, or lat and lon. Use when an agent needs today's weather or tomorrow's forecast for travel, events, logistics or a daily brief.
