Providing a METAR station code is optional, and if not supplied, the closest station to the latitude and longitude will be chosen. A list of nearby stations is printed to the log with level `DEBUG` if no station is supplied. Stations can also be found on the [NOAA website](https://www.cnrfc.noaa.gov/metar.php). Codes with only three characters, for example, `ADW` should be prefixed with the letter K, `KADW`.
One weather entity is created for each entry in the configuration. Hourly and day/night forecasts are provided through the `weather.get_forecasts` action. The time supplied for each forecast is the start time for the forecast. Sensors are also created as disabled entities after configuration and can be enabled by the user.
One weather entity is created for each entry in the configuration. Hourly and day/night forecasts are provided through the [`weather.get_forecasts` action](/integrations/weather/action--weatherget_forecasts). The time supplied for each forecast is the start time for the forecast. Sensors are also created as disabled entities after configuration and can be enabled by the user.
## Action `nws.get_forecasts_extra`
`nws.get_forecasts_extra` provides extra data in a form similar to `weather.get_forecasts`. See [`weather.get_forecasts` documentation](/integrations/weather/action--weatherget_forecasts).
| Data attribute | Optional | Description | Example |
| ---------------------- | -------- | ----------- | --------|
| `type` | no | The type of forecast, must be either `twice_daily` or `hourly`. | `twice_daily` |
```yaml
service: nws.get_forecasts_extra
target:
entity_id:
- weather.khou
data:
type: twice_daily
response_variable: weather_forecast
```
The response data field is a mapping of called target entities, each containing the `forecast` field.
`forecast` is a list of forecasted conditions at a given point in time that are not returned from `weather.get_forecasts`. The `datetime` and `is_daytime` attributes are still provided for context.
| Response data | Description | Example |
| ---------------------- | ----------- | -------- |
| `datetime` | The time of the forecasted conditions. | 2023-02-17T14:00:00+00:00 |
| `is_daytime` | Only set for `twice_daily` forecasts. | True |
| `detailed_description` | Only set for `twice_daily` forecasts. | 50% Chance of rain, otherwise partly cloudy with a high of 75F. |
| `short_description` | Short weather condition | Partly Sunny then Slight Chance Showers And Thunderstorms |
## Details
Details about the API are available in the [NWS API documentation](https://www.weather.gov/documentation/services-web-api). The [pynws](https://github.com/MatthewFlamm/pynws) library is used to retrieve data.
Details about the `weather.get_forecasts` action are available in the [`weather` documentation](/integrations/weather/).
