"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.

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 (

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 (

However nowadays, radar tools like RadarScope are widely available and detailed mesoscale models like the
HRRR can be viewed.
