What is the real-time weather at coordinates 121.47,31.23 (Shanghai)?

The current weather in Shanghai is 22 °C with clear skies. The humidity is 65% and visibility is excellent at 15 km. Should I also check if there's any rain forecast for the next hour?

According to Caiyun's minutely forecast, there is no rain expected in your area for the next 120 minutes. It will remain cloudy. Would you like me to check the daily forecast for the rest of the week?
