LightningCast

The ProbSevere LightningCast model uses images of visible, near-infrared, and long-wave infrared channels aboard GOES ABI to predict the probability of lightning in the next 60 minutes (QuickGuide). LightningCast has been used extensively by NWS forecasters since 2021.

Verification

These verification metrics, for LCv1 (ABI-only predictors) were computed from the GOES-16 CONUS sector, every 10 minutes, for approximately all of 2023.
