The animation above shows ProbSevere LightningCast probabilities over the Island of Guam for 80 minutes near noon local time on 6 October 2022 (imagery taken from this RealEarth website). The animation above shows LightningCast probabilities increasing from 0110 UTC (when a 10% contour appears) through 0140 UTC and 0150 UTC (when a... Read More
GOES-16 Visible Imagery, in the mp4 animation above (click here for an animated gif), shows convection initially over central Wisconsin at sunrise moving eastward over Lake Michigan into lower Michigan.

At the request of the National Weather Service forecast office in Guam (where the National Weather Service’s day begins), CIMSS is computing a small region of LightningCast Probabilities that uses Himawari-8 data. The Guam forecast office issues a lightning ‘advisory’ if lightning is possible or occurring within 20 mi of... Read More
