Day Cloud Phase Distinction imagery, above, from the GOES-16 CONUS Sector, shows the development of convection along the southern tier of counties in Wisconsin. LightningCast probabilities (the probability that a GLM observation will occur within the next 60 minutes) start to ramp up shortly after 1800 UTC, a 10% contour appears at 1826 UTC (in Rock County over southern Wisconsin), a 50% contour at 1851 UTC.

Hurricane Beryl made a (final) landfall along the Texas Gulf Coast, near Matagorda TX, at about 4 AM CDT/0900 UTC on 8 July. VIIRS imagery, above, from the SSEC/CIMSS Direct Broadcast antenna, shows infrared (I05, 11.45 µm) imagery and Day Night Band visible (0.7 µm) imagery around the time of landfall. It is noteworthy that city lights are unable to penetrate the thick clouds (some of the reduction in... Read More
GOES-16 infrared imagery, above, captures the landfall of Hurricane Beryl over Mexico’s Yucatan Peninsula near the town of Tulum at 1105 (UTC) (NHC Discussion). Beryl continues a brisk motion (15 mph) towards the west-northwest, so its time over land will not be very long. This will affect its subsequent strength over... Read More
GOES-16 1-minute imagery over Hurricane Beryl, above, shows the Category 5 (on the Saffir-Simpson scale) storm moving across the central Caribbean to the south of Puerto Rico. At the beginning of the animation the cold cloud tops are distributed symmetrically around the storm; by the end of the animation, some... Read More
