National Weather Service 7-Day Forecast in Slack

This n8n workflow enables instant weather checks via a custom Slack slash command /weather [cityname]. When users type the command (e.g., /weather New York), it converts the city name to coordinates using OpenStreetMap geocoding, retrieves detailed 7-day forecasts from the National Weather Service (NOAA/NWS) API, formats key data like temperature (°F/°C), wind speed/direction, and short summaries, then posts a structured response back to the Slack channel.

Benefits include real-time, location-specific weather updates without leaving Slack, saving time for teams needing quick forecasts. It's highly customizable—swap Slack for email, Discord, Teams, or Telegram; adjust formats; or schedule periodic reports. Requires a Slack app with slash command and post permissions, plus an n8n instance.

Ideal use cases: Remote teams checking travel weather, event planners verifying conditions, outdoor project managers, or automating daily briefs. Enhances productivity by integrating reliable government weather data into daily comms, with easy mods for global scalability.
