An isolated thunderstorm that was moving eastward across Maryland just after Midnight on 24 July 2017<\/strong><\/a> intensified as it crossed Chesapeake Bay, eventually producing a waterspout which moved onshore near Bay City (just southwest of Stevensville\/Bay Bridge Airport, station identifier KW29) — this tornado was responsible for 1 injury and EF2-rated damage (NWS Mount Holly PNS<\/strong><\/a>\u00a0 | SPC storm reports<\/strong><\/a>). GOES-16 “Clean” Infrared Window (10.3 \u00b5m<\/strong><\/a>) images (above; <\/strong>also available as a 23-Mbyte animated GIF<\/a>)<\/strong><\/em> showed that there were 3 distinct “pulses” when cloud-top infrared brightness temperatures cooled to the -71 to -75\u00ba C range (lighter gray pixels embedded within dark black regions)<\/em> before the storm produced the tornado at 0529 UTC. Since one of the default GOES-16 Mesoscale Sectors<\/strong><\/a> was providing coverage over the eastern US, imagery was available at 1-minute intervals.<\/p>\n

A comparison of 1-minute GOES-16 vs 15-minute GOES-13 (GOES-East)<\/em> Infrared Window images (below; <\/strong>also available as a 17-Mbyte animated GIF<\/a>)<\/strong><\/em> provided a convincing demonstration of the value of more frequent image scan intervals for monitoring severe convection. The improved spatial resolution of GOES-16 Infrared imagery — 2 km at satellite sub-point, vs 4 km for GOES-13 — also allowed for a more accurate depiction of cloud-top IR brightness temperature patterns and values.<\/p>\n
