How low can you go

Keith Bromley sent this email Monday.

“Mr. Turner,

“I see that the forecast low for here in Moscow tonight is 43 degrees — a mere 11 degree cushion from freezing. Not comforting to us who live in low-lying areas and frost pockets.

“So I have a question. If it were to freeze on the 24th of July, would that count as the last frost of spring or the first frost of fall?”
