After the 6" of snow Saturday night, and Sunday's high winds most of the day, we had a clear night with the stars and moon shining brightly. This morning it's 17 degrees, and supposed to get even colder as the week goes on. In our 15 years here the coldest was 13 one night last winter, and it looks like that could be beaten tonight.
I don't know if our cold is related to the ice storms and frigid weather of the northeast, but I hope those people are doing OK and warm up soon.
