OK, I looked it up. Average from 1979 to 1999 for me on December 17th was 29.1 degrees F.
Can we have it in non-freedom units, il even take a clothing layer comparison is the metric systemis spawn of Satan. Is this snow - t shirt weather?
29 is bundled up layered clothes, ice, and snow weather. 55 is a hoodie over your tshirt.
