Snow forecast notification help

Configuration

I want to create an automation to alert me if there is snow expected in the next 5 days. Don’t know how to write yaml and used chatgpt. I’m unable to get the notification to tell me what day(s) snow is expected. I am using weather.com. This is the closest I’ve come

alias: Snow in Next 5 Days (Weather.com)
triggers:
  - at: "4:00:00"
    trigger: time
conditions:
  - condition: template
    value_template: |
      {% for day in forecast[:5] %}
        {% if day.condition in ['snowy', 'snowy-rainy'] %}
          {{ true }}
        {% endif %}
      {% endfor %} {{ false }}
actions:
  - action: notify.mobile_app_iphone
    data:
      title: Weather Alert!
      message: Snowy conditions expected in the next 5 days.
variables:
  forecast: >
    {% set f = state_attr('weather.home', 'forecast') %} {{ f if f is not none
    else [] }}
mode: single

Are you sure your weather.home has an attribute forecast? Unless that’s a Template weather entity that you created, it is very unlikely. The forecast attribute was removed well over a year ago.

Weather.com is not covered by a core integration, so you need to tell us what custom integration you are using for us to help.

If it is the one by jaydeethree, its docs show the following:

The link in that screenshot leads to a post in this forum explaining the use of the weather.get_forecasts action.

alias: Snow in Next 5 Days (Weather.com)
triggers:
  - at: "4:00:00"
    trigger: time
conditions: []
actions:
  - action: weather.get_forecasts
    target:
      entity_id:
        - weather.home
    data:
      type: daily
    response_variable: forecasts
  - condition: template
    value_template: |
      {{ merge_response(forecasts)[:5]
      | selectattr('condition', 'in', ['snowy', 'snowy-rainy']) 
      | list | count > 0 }}
  - action: notify.mobile_app_iphone
    data:
      title: Weather Alert!
      message: Snowy conditions expected in the next 5 days.
mode: single

Thanks for your help. Yes that is the correct integration. Both automations work to notify me of snow in the next 5 days. Is there a way to have the notification say specifically what day the snow is expected on (monday, saturday ect.)?

With templates basically anything is possible…

alias: Snow in Next 5 Days (Weather.com)
triggers:
  - at: "4:00:00"
    trigger: time
conditions: []
actions:
  - action: weather.get_forecasts
    target:
      entity_id:
        - weather.home
    data:
      type: daily
    response_variable: forecasts
  - variables:
      days: |
        {%macro weekday(dt)%}{{- dt.strftime('%A')-}}{%endmacro%}
        {{ merge_response(forecasts)[:5] | selectattr('condition', 'in', ['snowy', 'snowy-rainy']) 
        | map(attribute='datetime') | map('as_datetime') | map('as_local') | map('apply', weekday) | list }}
  - condition: template
    value_template: |
      {{ days | count > 0 }}
  - action: notify.mobile_app_iphone
    data:
      title: Weather Alert!
      message: Snowy conditions expected on {{' and '.join((days|join(', ')).rsplit(', ', 1))}}.
mode: single
