Live weather (current conditions and a 3-day forecast for whichever city you pick) loads automatically when this file is opened in your own browser: Indianapolis comes from the National Weather Service (weather.gov) and every other city from Open-Meteo, refreshed every 10 minutes. Inside Claude’s hosted preview, outbound internet requests are blocked, so it falls back to simulated climate-based data; the badge above the screen tells you which you’re seeing. For official forecasts, check weather.gov.
