I was with a photography group that I have been with and I had just recently bought a digital camera that could film simple non HD video. I had no experience chasing or documenting storms and if you do want to do this I recommend that you seek real training or go with a person with experience because it can get dangerous. PLEASE NOTE: I do not recommend that you go out and chase storms. When I was filming this video I was not anywhere near a shelter and I thought I was going to get struck by lightning.
In 2011 I took a Storm Spotter training and a year later I took the advanced class and now that I had learned about storms I now feel that what I did back in 2008 was foolish. I did not have a NOAA Weather radio or mobile radar, which means that we were partially blind and we did not know that there were damaging winds that touched down not far from us. Lessons learned looking at this in retrospect.

Below is a video that I filmed in segments and found this footage today (yes, years later)
When I got home I heard that there was storm damage less that a 1/2 mile from where I was located while filming and if I recall correctly residents thought their area was hit by a tornado. I have tried several times searching for news reports and found that this was not a tornado but a severe thunderstorm with a strong isolated downdraft that generates winds that could be as strong as a EF1 Tornado. This particular storm had different clouds that showed both horizontal, vertical rotation, and lots of lightning strikes. This was filmed right after leaving Valley Forge Park where we witnessed torrential rain and a flash flood.
Reading more about that day, I found out that there was a hail storm in Chester County and another one in Elk Township NJ where Storm Spotters measured hail at 1 inch in diameter. (which is evidence of a severe storm) The clouds you see in the video and the pictures below show vertical development which is another warning sign of a severe storm. I could not find if there was a tornado watch issued that day.
Here are a few pictures from that day. You can see the clouds how the storm was moving by us, the clouds were swirling above us showing signs of vorticity.
