fixin to get plum nasty in central il

The coldest I can remember was back in the early 90s here. It was around -25F air temp. It got so cold that it actually cracked one of our front windows. And these were double paned insulated windows! Not really looking forward to this one. The house I'm in now is much less insulated than the previous one. Around here they're calling for maybe 6-8 inches. Really hoping that is an over-estimation, but I'm not counting on it. Yay.
