Monday’s weather in Prague was abundantly warm. I wore a black shirt over a T-shirt and after a half-hour of running around I was wishing I’d left the shirt home. And then it turned cloudy, and when it started thunderstorming around 5:30 pm it was hailing for a bit. Where did I get the obviously wrong idea that it had to be at least cool if not cold for hail to happen? I’m doing the research as we speak.
