Im in the DM Metro area now.
It was about 1 above today, which is cold, but not as bad as some try to say, when they use the feels like temp.
Forecast for -15 overnight. Which is cold, but most of us wont be outside.

Although working outside in the middle of the night was a regular occurrence for me for many years, which did suck on the nights it was below -20, but I worked in extreme far north Iowa and in the lower half of MN during those years.
Didnt mean to claim it is not cold, just that I hate all the new "feels like" crap a lot of people seem to use anymore.
That being said, if my family would, I totally would be living far south of here, as many years of working in all weather outside, I have had my fill of winter, and hate everything about it. So I would be in TX, AZ or FL probably at this point if I could.
So yeah its cold.
