If the storm comes in like they are predicting this will be a rare event. Here in OKC they are calling for -9 F on Monday and this will be an all time any day record low (at least back to 1848). Probably the same for where you are. The weathermen in this area are usually doom and gloom and sky falling chicken littles. They are so scared of missing a bad storm they over predict. What they are calling for now sounds like a Century event.

My suggestion is you invest in a set of Carhart's and Thermals. Make sure you are prepared for power outages for a a few days. Stay warm. Our local governments are not as well prepared to handle this as those up north.
