GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed thunderstorms which produced hail, damaging winds and tornadoes (SPC storm reports) across southeastern Idaho on 31 May 2018. Note that after 2102 UTC a pronounced “enhanced-v” infrared storm top signature was exhibited by the larger supercell which produced most of the... Read More
Suomi-NPP and NOAA-20 overflew tropical depression Alberto, at 0722 and 0812 UTC, respectively (orbit paths from this site), on 30 May 2018, and the near-Full moon provided ample illumination for the Day Night Band imagery, shown above. A motion to the northeast is apparent. Convection developed far to the north of the storm... Read More
A toggle between NOAA-20 VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) images at 0731 UTC or 3:31 am local time (above; courtesy of William Straka, CIMSS) showed Subtropical Storm Alberto when it was centered off the southwest coast of Florida on 27 May 2018. Note that NOAA-20 imagery is... Read More
GOES-16 (GOES-East) “Red” Visible (0.64 um) images (above) showed an isolated supercell thunderstorm that moved south-southwestward across North Texas on 25 May 2018 — producing a nearly continuous swath of large hail and damaging winds (SPC Storm Reports). Beginning at 2000 UTC, a Mesoscale Domain Sector was positioned over the area, providing images at 1-minute intervals. In... Read More
