Sub-HP (high precipitation) supercell near Philo, Illinois (panorama)
September 21, 2012:
This panorama here is a capture of a sub-supercell thunderstorm which was in rural Southern Champaign County near Philo, or about 6-8 miles away from Urbana, Illinois. Definitely one of my wildest days of this said "chase season" in Illinois; this late summer and fall have been the "spring" of our season since we've had such a horrible drought in the area.
Finally to add some more information on this day, I was feeling really sick and had a pretty bad cold although nothing stopped me this afternoon (09/21/2012) from witnessing some stormin' goodies in rural East Central Illinois. The SPC had a small-scale slightly enhanced risk area prior to a mesoscale discussion issued within the early afternoon hours regarding the probability that severe weather was likely. I happily scooted northbound along Route 130 from Coles County to Champaign County to witness a strengthening outflow dominant sub-supercell thunderstorm just in the outskirts of Urbana, near Philo.
I panorma'd this sucker and since this day I consider it to be one of my best shelf cloud captures yet of 2012.
