Well I can't image that the rest of the country is below freezing except the southwest and some of the west states.
Here it is in the 70's for the high and 40's for the low.
The lowest I have felt here was about 30 for the high for a few days a long time ago, like 12 years ago. It snowed here for a little bit. Of course I could not live where the snow is a few feet high and the temp is around 0.
