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
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
This blog post shows satellite imagery with a Singapore Airlines Boeing 777-300ER that encountered severe turbulence while flying over southern Myanmar (information from flightradar) at 0749 UTC on 21 May 2024. This graphic from Sarah Griffin, CIMSS, shows the turbulence location/time; other graphics/animations from this event are in this directory that Sarah Griffin created.LightningCast probabilities...

A period of high-based convection to the east and northeast of Hawaii was producing occasional lighting on 3 June 2024, as shown in the animation above. LightningCast Probabilities plotted show values around 50%, and lightning is occurring. Note that the Flash Extent Density colorbar has been modified to have a... Read More
