"We're blowing the pants off HRRR," said Luke Peffers, ClimaCell senior vice president.
The HRRR model is a real-time 3km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model.
As this weather system unfolded, high-resolution real-time data from the MRMS and HRRR models were extracted and ingested into advanced risk models to determine where damaging hail and high winds were actually occurring and to create the hail and tornado/wind intensity footprints.
For example, the HRRR modeling system is initialized and run each hour to 18 h with 3-km grid spacing using the WRF-ARW model.
Comparisons between (a),(c),(e) observed soundings launched from NCSU and (b),(d),(f) modeled soundings from the HRRR near Raleigh-Durham International Airport (RDU) at approximately (a),(b) 1700, (c),(d) 1900, and (e),(f) 2100 UTC 24 Feb 2016.
The orographic response was likely further modulated by thermodynamic effects, as evidenced in composite vertical profiles of equivalent potential temperature and relative humidity from the NOAA operational High Resolution Rapid Refresh (HRRR; Benjamin et al.
Even the best available model, the HRRR (High Resolution Rapid Refresh) reaches its limits.
6, which compares the diurnal distribution of convective available potential energy (CAPE) derived from the CLAMPS-1 AERI retrievals in the spring of 2016 to the 12-h forecasts from the High-Resolution Rapid Refresh model (HRRR; Benjamin et al.
However nowadays, radar tools like RadarScope are widely available and detailed mesoscale models like the HRRR can be viewed.

Some of the most commonly used aviation models are the RAP (Rapid Refresh), HRRR (High Resolution Rapid Refresh model), and NAM (North American Model).
