It's really likely to hail when it's hot and unsettled with thunderstorms. Hail forms way high up in the cold atmosphere and churns around up there in cells, getting bigger and bigger until it falls on the innocent. We're known for volatile weather here - it comes from not being near an ocean. You're a California boy, you have totally different (and probably equally weird) weather.

It took over a day to melt, even though it was in the 60s the entire time. And if you drive a mile in any direction from us, there was no hail, just rain. Very local. Lucky us, huh?
