National Weather Service

The National Weather Service API provides access to current weather conditions, detailed forecasts, and active weather alerts across the United States. Data includes 7-day forecasts in 12-hour periods, hourly forecasts, gridpoint-level forecast data at ~2.5km resolution, active severe weather alerts by state or zone, and real-time station observations. Coverage spans all US states and territories through a network of local Weather Forecast Offices. The API is free, open, and requires no authentication beyond a User-Agent header.
