A large supercell, which formed and moved near Denver eastward past Aurora earlier on Wednesday, produced tremendous amounts of hail which accumulated in many areas. The storm also produced a lowering wall cloud, which was observed by many storm chasers, and a possible tornado touchdown east of Denver. The variety of pictures received via social media showed the accumulating hail (a relatively rare occurrence, but more common out west due to colder air aloft) for the second straight day in Colorado. 5″ (yes, 5 inches) of hail fell in parts of Denver.
The maturing supercell also tracked nearly directly over the radar site at KFTG and the Terminal Doppler radar site at TDEN. The “shadowing” effect and the black hole/circle in the middle of the storm is a phenomenon not too often observed. When heavier precipitation moves directly over a radar site, the radar beam cannot register precipitation which is immediately near it’s location. In essence, the precipitation is falling below the radar beams, which shoot outward and upward from the radar site.

The reported tornado has not been confirmed yet as of Wednesday afternoon. Nevertheless, multiple storm chasers tracked and observed the storm at it’s peak. This week and weekend is one of the busiest storm chasing weeks of the season, as many head west to track and observe organized severe weather events in the Central and Western United States.
