Where to see this radar

The National Weather Service publishes no web loop for terminal radars, so the image above is ours: HookEcho reads the TDCA products straight from the NOAA archive and renders them at the TDWR's own resolution. In the app you get the rest — reflectivity, velocity and dual-pol at every tilt, with warnings, storm reports and lightning drawn over the same map.
