JACKSONVILLE, FLa. -

Heading into a mild week weather-wise for Southeastern Georgia and Northeastern Florida, but that's not necessarily the case around the rest of the United States.

While we enjoyed warm weekend days -- including a 81 degree high on Monday that tied a 125-year record -- Arizona's Grand Canyon Airport hit 20 degrees below zero on Sunday, tying the previous record set on Dec. 23, 1990 and Feb. 1-2, 1985 for all-time low.  (The only caveat to this record is that the record keeping began merely in 1976 for this reporting station, so it is a rather shallow field of research respectively.)

In Augusta, Ga., where they play the annual Masters Tournament, the temperatures were closer to our mild weekend weather.  The Bush Field Airport saw 79 degrees -- tying a record set in 2005.  All of the Southeast saw above average temperatures this weekend, but some locations set new records for high temperature of the day.  Columbia, S.C., broke its previous record of 77 degrees from 2005, with a new high temp of 78 degrees.  Macon, Georgia reached 77 degrees and Columbus, Ga., hit 75 degrees -- both breaking their previous records of 74 degrees from 2000.

On the contrast, West Yellowstone, Mont., got close to its record low of 36 degrees below zero, with a low of 39 degrees below zero.  

While you might expect Toronto to be among the freezing, yet they were above average with an afternoon high on Sunday of 48 degrees. Compare that to their average afternoon high of 27 degrees -- must have been downright balmy for that neck of the woods.

Hope you didn't plan your vacation for Mexico this week- while they normally reach afternoon highs in the low 70's. Sunday they only hit 46 degrees in Mexico City.  It was actually warmer in Buffalo, N.Y., Sunday with a high of 65 degrees (average highs for Sunday  there are in the low 30's) than Mexico City, Mexico.  And if you were gambling on warm weather in Vegas- yesterday- you lost big! Las Vegas typically hits 60 degree on days like Sunday but lows were as cold as 17 degrees  in some parts of the city.  Bursting pipes and other cold-weather-related issues arose due to that overnight low.
