There is a new model in our family of 10+ weather forecast models — HRRR. It provides a great forecast for the continental US.

HRRR is High Resolution Rapid Refresh. The model was developed by the National Oceanic and Atmospheric Administration (NOAA) of the US. These are the main features:

  • Real-time 3 km (1.9 m) grid resolution.
  • Hourly updates.
  • Radars' data — the unique advantage of HRRR. It is assimilated every 15 min over a 1 h period. It gives short-range weather forecasts (forecast depth is 18 hours) with pretty good accuracy. So the forecast is definitely worth looking at.

In HRRR you find temperature (2 m), gusts (10 m), wind speed and direction (10 m), total cloud cover on your spot forecast screen.

Also, you can add the parameters to your custom weather profile.
