Predicting if severe storms will produce hail

The shape of a severe storm such as the one pictured here is a major factor in whether the storm will produce hail and how large the hailstones are. National Center for Atmospheric Research scientists are experimenting with a new machine-learning technique that can process images to weigh the impact of storm shape and potentially improve hail forecasts.
