The HRRR model is short-term, looking 15 hours out.
As these are not fine-grained mesoscale models, there are no "radar forecasts" like there are with the HRRR.
Weather modeling
The HRRR is a tool delivering forecasters a more accurate depiction of hazardous weather to help improve our public warnings and save lives.

WindLogics incorporated forecasts from these improved NOAA models into machine learning energy prediction algorithms, while the AWS Truepower team developed and operated in real time an experimental nine-member optimized ensemble forecast system for WFIP that utilized RAP and HRRR for initial and boundary conditions.
Because of the focus on short-term forecasts (up to 15 h), the principal NOAA models used during WFIP were the hourly updated 13-kmresolution RUC, the 13-kmresolution RAP, and the 3-km-resolution HRRR (Fig.

Every hour, the HRRR model forecasts 15 hours into the future using the most recent observations available.
One hour before supplying a forecast, the HRRR creates a 3D image of the atmosphere.
