Why it snowed yesterday

My son, his wife and two little boys just returned from a trip to Brazil, bringing with them her brother and his new wife. The brother was here in the winter time just before the Olympics and has experienced snow and freezing cold. Not so his wife. She was tickled to pieces that although her first day here it was almost 80 degrees, the next day it snowed! Living as they do near the equator, the temps don't vary much year-round. So this is indeed a new experience. And here in Utah we are always happy to oblige those who'd like to see some snow for the first time.
