NOAA HRRR short-range forecast (CONUS, 3km)
18-hour hourly forecast. UI dimension we're not committing to yet.
What this is
High-Resolution Rapid Refresh — NOAA's 3km hourly forecast model for CONUS, refreshed every hour. The operational US forecast model that ag users care about.
Why we surface it
Spray windows, frost alerts, GDD accumulation turn on the next 18 hours. HRRR is the data behind them — but we're parking until Pioneer use cases push for it.
