While the warmth may finally be beginning to wane in some areas, the number of ways to express how unusual it was is not.
Thousands of records, some thought to be unbreakable, have fallen over the past couple of weeks from the High Plains to the East Coast, and north into Canada.
The unusual warmth has many questioning why, and wondering if this could end up being the new normal. From climate change to ocean temperatures to debris from last year's tsunami, Jillian MacMath has more on the theories offered up by AccuWeather.com's meteorologists.
Though the lasting legacy of the warm spell could end up being one of the above, in the short term, meteorologists and climatologists alike are still struggling to digest the staggering nature of the records that have been broken over the past dozen or so days.
