1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) are shown with and without an overlay of GLM Flash Extent Density and contours of Lightning Cast Probability from 1530-1915 UTC on 01 June 2023 — the time period covering outdoor graduation ceremonies at the Air Force Academy in eastern Colorado. LightningCast provided good lead time, with Probability values over the Air Force Academy first reaching 75% at 1619 UTC — the first pixel of Flash Extent Density (FED) over the Academy location was at 1815 UTC (with FED becoming more frequent and widespread over that area after 1851 UTC).
