August 6th, 2002 Lewistown, MT Awesome LP Supercell
Last Updated on Sunday, 10 January 2010 00:48 Written by Roger Hill

August 6th was a simple an fun chase day. For the second day in a row significant severe weather was a sure bet. I spent the night in Lewistown, MT and didn't have to leave. By lat afternoon an HP supercell developed just east of town. This storm produced high winds and large hail. Another, by far prettier supercell developed just west of the first. It became my favorite LP supercell of the year as it went on to survive for 6 hours and produce softball sized hail. Check out the photos below.
