Yep, Cor, we're dropping from 37ºF (3ºC) this afternoon to 6ºF (-14ºC) by morning. Already down to 24 (-4ºC) here.
Just for 2 days tho. The last one ended today, the next one begins tomorrow. The last one didn't get anywhere near as cold as the first cold wave. We hit -11ºF (-24ºC) with 45MPH (72 Km) winds during that one.
