Article talks about how records are determined and what would happen if they went outside certain seasonal date parameters.

As far as average temperatures go, Chicago is at its third-coldest season on record, at 18.8 degrees for “meteorological winter,” or December through February. But widen the time frame to include November and March, Castro said, and who knows how cold the season would be.

“November through March periods would be something to look at this year to compare to previous seasons,” Castro said. “We’ve never done that before. We’ve never had to. Meteorological seasons stood for themselves.”
