    Today is going to be a very frigid 12/30 for much of the US.

    Does the data include 2017? Most of the country is below 45 degrees f, and the upper graph does not not show today’s wide-spread arctic blast.

    I remember 1983 very well. I was 7 years old and living in Houston. I remember it very vividly… VERY COLD, so cold that the outdoor fish pond froze over. It was actually thick enough to walk on it. http://www.chron.com/sports/outdoors/article/Effects-lessons-of-1983-freeze-evident-on-Texas-5092926.php

    Do you have the source reference or source data for this? I’d like to poke at some people with it.
