Identifying a cold front on NEXRAD

Added on: July 15, 2014         Duration: 7 minutes

Frontal systems are normally the focal point for deep, moist convection also known as thunderstorms. We normally see these frontal boundaries depicted on the surface analysis chart. However, the mean sea level surface analysis chart is only issued every three hours and is normally 90 minutes old after it gets posted. Using the NEXRAD radar image can be a great way to identify where the front may exist in real time. Fronts are boundaries in the atmosphere that separate two distinctly different air masses consisting of air of differing density defined by temperature and moisture. These density differences may show up readily on the NWS WSR-88D NEXRAD Doppler radar especially if the radar is in clear air mode. This workshop explores one such case where severe storms erupted along a boundary identified on NEXRAD radar.
