The default setting shows temperature forecast below towns names.
When you set Forecasted weather (Tempo previsto) the local forecast of the same parameter as the map layer is displayed.
For example here, with the Rain layer, the figures below the towns in UK are rain forecast in mm.

If you select Wind, the wind speed forecast will be displayed below towns names.
