NOAA HRRR short-range forecast (contiguous US, 3km)

An 18-hour hourly forecast at 3km resolution, refreshed every hour.

What this is

High-Resolution Rapid Refresh — NOAA's 3km hourly forecast model for the contiguous US, refreshed every hour.

Spray windows, frost alerts, and growing-degree-day accumulation all turn on the next 18 hours. HRRR is the forecast model behind them.
