It may be summer solstice, but summer isn’t quite here yet, says Cliff Mass, professor of Atmospheric Sciences at the University of Washington and KPLU's weather expert.
The reason, says Mass: “Summer solstice … is astronomical summer. It is not necessarily meteorological summer,” said Mass.”
“And in the profession, we all joke—and it’s not much of a joke—that summer starts here in Seattle on July 12. And in fact, there’s a lot of truth to that,” he said.
