That cold mass from Russia is settling down on Interior Alaska too. Oh well, -20 will seem warm again after this next cold spell. We're supposed to hit -40 (F) tonight. Cabin fever is setting in a bit, and dang it all, someone hid my knives again. LOL ;)
I can tell when it gets below minus 20, because the cold water pipe to my bathtub freezes. I turn on the tap and nothing comes out. It used to freeze around zero when we first moved in here, but we took off some clapboards and sheathing and put in some insulation, so things are a little better.
Fortunately the plumber used plastic for that length of pipe, so it freezes and thaws without bursting.
If Alaska is getting the artic air now, I imagine it will start moving east sometime later this winter.
