The weather seems a tad apocalyptic, don't you think? Look at the scale for the temperature graph -- each division has to represent 20 degrees!

Maybe we'll set a record high and a record low on the same day?

Freaky.

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.

It was once mid-40s as a HIGH in June. I was up in the middle of Anoka County at a grad party and genuinely shivering. In June!
