Don Rig yourself an inline air tank in your basement if you can't move the compressor indoors with you. Setting up a IR spotlight to shine on your compressor might help it with it's cold bones and getting started. In regards to the low humidity, you'll have to fire up a room humidifier. Get the humidity above 40%.
Here is Wisconsin we share the cold, but Minnesota takes more of the brunt from the winds coming across the Dakotas and out of Canada. We've had minimal snowfall so far, mostly rain and mild temperatures. They say now we will have a white Christmas, but it will be a very light snowfall.
I know I'm nuts, but I'd like to see a nice blizzard with a ton of snow. Just give me 24 hours warning that it is coming so I can make a quick trip to the grocery store for survival rations...brandy...chocolate...popcorn...couple steaks....chili....soups...comfort foods. We could hold up for a week or so. Longer if I don't run out of modeling supplies!
