Show the weather forecast

[Deuchnord]

Is your feature request related to a problem? Please describe.
The application currently does not give weather forecast, so we are forced to check it by ourselves.

Describe the solution you'd like
Add a feature that checks the hourly weather forecast via OpenWeather API and displays a summary on the standard output.
