The Gore Effect© strikes the Volunteer State:

NASHVILLE, Tenn. (AP) — Cool weather that led to record low temperatures will take its time leaving Tennessee.
The National Weather Service reported the temperature in Chattanooga dipped to 59 degrees Monday morning, eclipsing the previous record for the date of 60 degrees, set in 1947.
Nashville dropped to 59 degrees early Monday and Knoxville bottomed out at 60 degrees — both tying records for the date.
Early Sunday morning, the Tri-Cities set a new low for the date, reaching 54 degrees and breaking the old record of 55 degrees, set in 1984.
NWS forecaster Mary Black in Morristown said the cool weather is a gift from Canada, with a strong high over the western U.S. allowing a trough of cool Northern air to slide into the Southeast.
Black said normal highs in the upper 80s aren’t likely until the weekend.

Yeah, blame Canada. Planet Gore readers know who’s really to blame.
