So, not sure if I can explain this well enough, but here goes. Is there such a thing as a super gust front or meso-gust front? I like to think I am pretty aware of a standard gust front signature on radar, but I just saw something interesting on College of DuPage's Satellite loop. If you click on the GOES-East Washington DC (Localized Sector) and set it to 96 frames. Up in Eastern Central PA around Pittsburg watch at frame 66 (18:11:17 UTC) to frame 88 (20:06:17 UTC). There is a very large bow arc that appears to shoot off a large cluster of storms and races south east. This is now triggering more storms out in the west. This seems much larger than a typical gust front, or at least that I can recall. Anyone chime in to what I was looking at? Thanks for any help.
