GOES-16 Visible imagery (Band 2, 0.64 µm) from Mesoscale Sector 1, above, show the evolution of Helene for about 90 minutes shortly after sunrise on 26 September. Strong convection is wrapping around a center that occasionally has an eye-like characteristic. At the time of the animation, Helene was a very... Read More
GOES-18 True-Color imagery, above, from the CSPP Geosphere website (link to animation above), shows convection moving over northeastern Wyoming, leaving in its wake a series of smoke plumes: wildfires caused by lightning. The screenshots below were captured from the Real Earth instance of NGFS imagery (link), and they show LightningCast probability and Flash... Read More
GOES-16 Band 2 Imagery from Mesoscale Sector 1, from the CSPP Geosphere site, above (click here for an animation with state/country borders), shows convection developing along the northern shore of Lake Erie and moving into Buffalo. One of these convective towers generated a weak tornado (storm report) at 1649 UTC.The large-scale environment on this... Read More
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. The... Read More
