Quick solution to generate the rows dynamically

            cards: >
              [[[
                let rows = [];

                function generate_weather_row(index) {
                    var row = {
                      'type': 'custom:button-card',
                      'template': 'popup_weather_row',
                      'entity': entity.entity_id,
                      'variables': {

                      }
                    };
                    return row;

                let index = 0;
                for (let forecast in entity.attributes.forecast) {
                    rows.push(generate_weather_row(index));
