[Plugin: WP Geo] Wpgeo with google weather forecast?

In what way in the weather traveller plugin not working?

because there isn’t forecast, but only the weather of the day and without any icons.

I think that was the intended functionality of the plugin. I think the author developed it just to get and store the weather at the time the post was published – to log the weather conditioned as he travelled around.

Displaying a current forecast would need to be built as a new plugin.

The Google Weather API was shut down so we must find another solution

Here’s another API that could be used:
