(Friday afternoon)
"Do you know about clouds?"
"What about them?"
"Well, what are those ones over there called?"
"Those are cumulus. Most definitely."
(a bit later)
"What does it mean when they get taller like that all of a sudden?"
"Oh, a good chance of showers."
(A bit later)
"Are they getting darker?"
"That's just because we're underneath them now."
(A bit later)
"Wow, that approaching rain is really loud!"
"Ow, my head! That's not rain, that's hail!"
Got a serious drenching and some impressive lightning strikes that evening; it rained again Saturday night but weather was OK during the day.
