In September, 2012, I chased this storm from Pennsylvania to the ocean, and while it had lost its severe warning by this point, it made a cool boundary as it went out to sea in Asbury Park, NJ.

In May, 2012 I chased the first thing to pop in a severe thunderstorm watch area and was able to chase a storm near Cottonwood Falls, Kansas from an intense updraft to the south of an existing non-severe thunderstorm into a severe-warned monster. The storm morphed into a massive rain system that raged all night, losing strength following me all the way back to northeastern Oklahoma.
