Hail spike example

You need to turn off Canadian Noise Radar Reduction to see it and don't forget to reload the page when you make a change to a setting. When hail is really large you can get a spike. "A hail spike or three body scatter spike (TBSS) is an artifact on a weather radar display indicative of large hail. They are identified by a spike of weak reflectivity echoes that extend out from a thunderstorm, and away from the radar site." https://en.wikipedia.org/wiki/Hail_spike
