Description

HRRR Alaska is a high resolution model offering short term forecasts updated every hour.

The following description has been taken directly from the official documentation

The HRRR is a NOAA real-time 3-km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh

There is a short video available which describes the model further.

Storms: Note that this model is intended to be able to resolve storms. Storms can change rapidly, and as this model is both updated frequently (every 3 hours) and has a high resolution, it may be the best choice for watching storms develop and progress.
