Prepare store weather alerts from Open-Meteo with Claude drafts to Slack

## Rain, heat or cold ahead? Tell each store in time Every afternoon the workflow reads the free Open-Meteo forecast (no key) for each store in your Stores tab. Code flags the days with rain, heavy rain, heat or cold, using your limits. For the flagged stores, Claude writes a short prep list for the staff and a draft message for customers, and code checks both: every temperature, probability, amount and date must be in the forecast, the customer draft must fit your length and avoid your banned words. Slack gets one message per store. ### How it works 1. Read the stores (name, lat, lon, notes, contact). A wrong coordinate stops the run with a clear message. 2. One forecast request per store (default 3 days). Code turns the flagged days into numbered facts. 3. Claude writes with the fact ids it used; checks mark anything that fails with a warning. ### Setup 1. Blank Google Sheet: paste its ID in Spreadsheet ID, run Run once, select the sheet in the Google Sheets node. 2. Fill the Stores tab (right-click a place in Google Maps to copy lat and lon). 3. Credentials: Google Sheets, Anthropic, Slack (pick a channel). 4. Set the limits, language, time zone and banned words in Config. Publish. ### Note Forecasts can be wrong. Read the customer draft before you send it.
