It was really interesting to watch the weather guys during that storm. They have a radar now that can detect hail within a large thunderstorm. The radar shows green (light rain), to yellow (heavier rain), to red (heavy rain), to pink (small hail), to white (large hail). And they can click on points in the pink and white and it will estimate the hail size. As the storm was moving across north TX the radar white hail core was pulsing going from a large core to a smaller core and back to large again, never going away. And as the weather guy was clicking on the radar within the core, it was showing hail from 2.5" to 4" dia. Pretty accurate as that was what was actually observed on the ground.

One report estimated that pea size hail can fall at 20 mph, and baseball size hail at 100 mph. Didn't say about softball size.

That is in addition to the other (doppler) radar that shows rotating winds within a storm indicating a possible tornado. They are getting better and better on giving out warnings of impending dangers with enough time to prepare, at least within an hour or so of it hitting.
