1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed severe thunderstorms that moved across Pennsylvania on 02 October 2018, producing large hail, damaging winds and a few tornadoes (SPC storm reports). A parallax-corrected version of the animation — which shifts the location of SPC storm reports northwestward, to be more closely aligned with the storm-top features (assumed to be at a mean altitude of 12 km, based on 00 UTC Pittsburgh rawinsonde data) seen on satellite imagery — is available here.

The corresponding GOES-16 “Clean” Infrared Window (10.3 µm) images (below) indicated that the coldest cloud-top infrared brightness temperatures were in the -60 to -70ºC range (red to black enhancement).
