What is NEXRAD radar ?
"NEXRAD" is short for NEXt generation RADar and refers to the nationwide network of Doppler radar sites installed by the National Oceanographic and Atmospheric Administration (NOAA).
NEXRAD
NEXt-Generation Weather RADar. Technologically-advanced weather radar being deployed to replace WSR-57 and WSR-74 units in the US.

DOWNBURST
A severe localized downdraft from a thunderstorm or shower. This outward burst of cool or colder air creates damaging winds at or near the surface.
A limitation in NEXRAD rainfall estimates whereby abnormally high reflectivities associated with hail are converted to rainfall rates and rainfall accumulations.
