AUTH NONECORS ✓AGENT ✓HTTPS ✓COMMERCIAL ✓

The US National Weather Service's public API: start from a latitude/longitude to resolve the forecast grid point, then pull forecasts, hourly data, active alerts and station observations. Data is US-government public domain. Keyless, though it wants a descriptive User-Agent.
