Customising the BOM Weather and lovelace - now in HACS

You need to create a triggered template sensor. Like this:

Though I’d replace the time pattern trigger with a state trigger that monitors the weather entity for updates,

template:
  - trigger:
      - platform: state
        entity_id: weather.whatever
    action:
      - service: weather.get_forecast
        data: etc...
