A 2-panel comparison of GOES-13 (GOES-East) Visible (0.63 µm) and Infrared Window (10.7 µm) images (above) showed a band of thunderstorms oriented southwest-to-northeast across northern Virginia and northern Maryland late in the day on 30 July 2016. Cells within this band produced very heavy rainfall and extreme flash flooding at Ellicott City,... Read More
A nighttime image (above) of the Suomi NPP VIIRS 11.45 µm – 3.74 µm Infrared brightness temperature difference (often referred to as the “fog/stratus product”) showed the development of narrow fingers of river valley fog in parts of southwestern Wisconsin, southeastern Minnesota and northeastern Iowa at 0735 UTC or 2:35...

GOES-13 (GOES-East) Infrared Window (10.7 µm) images (above) showed the formation of tendrils of transverse banding along the northern semicircle of decaying mesoscale convective systems as they moved eastward across Nebraska and Iowa on 19 July 2016. Pilot reports of turbulence are plotted on the images, along with Turbulence AIRMET polygons issued at... Read More
GOES-13 Infrared Window (10.7 µm) images (above; also available as an MP4 movie file) showed a series of mesoscale convective systems that moved across northeastern Minnesota, northwestern Wisconsin and the Upper Peninsula of Michigan during the 11 July – 12 July 2016 period. Some of these storms produced tornadoes, large hail, and damaging winds (SPC storm reports)... Read More
