NOAA Image of the Day
A new high resolution weather model developed by NOAA's Earth Systems Research Laboratory in Boulder, Colorado was made operational by the National Weather Service. The High Resolution Rapid Refresh (HRRR) model generates extremely detailed 3-kilometer resolution data for a multitude of 2-D and 3-D variables, each with 15 minute intervals. This spatial and temporal resolution is a great improvement over previous operational models and will be critical for predicting rapidly evolving severe weather. This image from the September 30, 2014 18z run shows the temperature of the surface. Clearly visible is a cold front moving across the plains that is bringing severe thunderstorms to areas in South Dakota and Nebraska.
Watch one of the developers, Stan Benjamin, discuss the development of high resolution models like the HRRR here.
