That is a bit of a swing, though such a shift over 24 hours isn't all that unusual in my experience. I recall sometime in the early 1980's I was working on a dairy farm in southwest WA. Just before Christmas we had temperatures in the low double (perhaps even single at times) digits for nearly a week. That was unusual for the area and all sorts of plumbing had frozen and had to be piped around, as flowing water is rather necessary on a dairy farm. Christmas day it was just myself and a milker at the dairy, everyone else, including the owner and family, had traveled away. A chinook wind came in Christmas Eve and everything thawed, water pouring out everywhere. Of course there were no hardware or plumbing stores open nor plumbers to be found. Somehow I got through it, though it was one of the longest working holidays of my life.
Where I live now in southeast WA (on the family farm, zip code 99330) the forecast is for a high of 22 F and a low of 11 F, with a current temperature of 14 F. I am SO happy there are no livestock here I have to worry about. I am on call all weekend for the mortuary I work for, but the roads are bare and driving conditions good in the event I need to go out.
