Human memory is remarkably shortsighted.
I well remember mild winters with December days in the high 40s into low 50s back in the 1980s. I remember a Christmas one year where I wore shorts. In Maryland. I remember very mild New Year's. Along with the cold ones, of course.
We had a few weeks of cold in late December, and it's mildlish cool right now, getting cold at night, which is typical for December.
The forecast does seem to be somewhat unreliable this year. Just a few days ago it was calling for close to 70 this weekend before dropping to the mid-low 40s all next week and Christmas Day was supposed to be 42! Then suddenly this weekend is 50 high instead and next week is closer high 40s into 50.
Who knows what it will be in a few days
