GOES-16 ABI and GLM data posted on this page are preliminary, non-operational and are undergoing testing

Strong morning thunderstorms with a few severe weather reports, and abundant heavy rain (24-h totals ending 1200 UTC on 12 July 2017, from here), spread over the northern part of the GOES-16 default western Mesoscale Sector on the morning of 12 July 2017. The animation above shows the GOES-16 Advanced Baseline Imager (ABI) 10.3 µm imagery with Geostationary Lightning Mapper (GLM) Lightning Flash event locations superimposed, at 1-minute timescales. The top of the default Mesoscale Sector cuts through central Wisconsin.

A comparison of Suomi NPP VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) images on 12 July 2017 (above; courtesy of William Straka, SSEC) shows the large iceberg (named A-68) that had separated from the Larsen-C ice shelf in Antarctica (Project MIDAS).

===== 13 July Update =====

A 12 July vs 13 July comparison of VIIRS Infrared Window and Day/Night Band images (below) revealed a slight expansion of the ice fracture, as Iceberg A-68 slowly drifted away from the Larsen-C ice shelf.
