Connects directly to the National Weather Service API to pull forecasts, alerts, radar data, and station observations across the US. You get tools for querying active alerts by zone or region, retrieving grid point forecasts, and accessing aviation products like TAFs and SIGMETs for flight planning. The most called tools are office queries, alert lookups, and point data retrieval, which makes sense if you're building location aware weather features or need to layer NWS data into your application. Useful when you need authoritative US weather information without managing API keys or parsing NWS's quirky response formats yourself.
