Cold, Colder, Coldest

Every time I think it can't get any colder, it does. This has, so far, been the worst winter I can remember. We currently have at least a foot of snow on the ground (more like 2-3 feet where it has drifted) and today there is a HIGH of -1 degrees. There is a windchill warning of -30! What is going on? Needless to say, Meiby has not left the house in several days. She's doing a pretty good job of using the puppy pads (she still "misses" occasionally) but she's getting a little stir crazy. Poor pug! I can't wait until it's warm enough to take her on walks again...
