WAFF's "First Alert Doppler Radar" (formerly "Live Stormtracker Doppler"), which was located in Limestone County just off of US 72, was destroyed when it was hit by a large and violent tornado (which produced EF5 damage in nearby Tanner, approximately 10 miles (16 km) away from the radar site) on April 27, 2011. A camera mounted on the tower ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
As the storm crossed US 72 in eastern Limestone County, the tornado destroyed a Doppler radar operated by Huntsville NBC affiliate WAFF (channel 48) and continued into East Limestone, a heavily populated area of Limestone County where homes in subdivisions were damaged or destroyed at high-end EF3 strength.

Vertical cross-section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by higher reflectivities aloft, forming a kind of dome of weak echoes.
Radar/Satellite IS: Core, Mini-Core: 2003–2022: A regional composite of visible satellite and radar data, showing the movement of weather systems and precipitation over a five-hour period; this product often alternated with the Local Doppler Radar during the Core and Mini-Core playlists. Regional Doppler XL: Core: 2000–2003
Strong mesocyclone on a thunderstorm near Tuscaloosa, Alabama, that was analyzed as fitting the characteristics of a TVS.It was associated with a tornado.. A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis.

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
