Cool weather has broken a previous low temperature for July 21 in Nashville that was set when Rutherford B. Hayes was president.
When the temperature at the National Weather Service station dipped to 58 degrees at 5:30 a.m. on Tuesday, it wiped out the previous record low for the date of 60 degrees, which was set in 1877.
NWS forecaster Bobby Boyd noted it was the third consecutive morning when Nashville either tied or broke a daily low temperature record.
Temperatures were cool, but did not break records at several Tennessee cities.
Knoxville dropped to 59 degrees Tuesday morning, Chattanooga had 60 degrees, Tri-Cities recorded 58 degrees and Memphis was 69 degrees.
Nashville dropped to 59 degrees early Monday and Knoxville bottomed out at 60 degrees -- both tying records for the date.
Nashville's high temperature on Sunday was 77 degrees, a record low for a high temperature on July 19. The previous record was 79 degrees set in 1897.
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.
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.
