A White Christmas and Travel Problems in Dixie

It's the first White Christmas in Atlanta in over 100 years.

The snowfall that began Saturday morning will deposit 1 to 3 inches on metro Atlanta, 2 to 4 inches in the northern counties.

Sunday's high will be just 33,  and Monday's just 34.  Above-freezing temperatures -- low 40s -- may return Tuesday, and loosen winter's icy grip on local roadways.

Heavy snow weighed down tree branches, causing them to fall on power lines in north Georgia. About 400 customers were without power, according to the Georgia Electric Member Corporation.

Saturday will start out with a wintry mix of sleet and rain that should change to snow as dry Arctic air collides with warm clouds from the Gulf of Mexico. The wintry mix should cease by Sunday afternoon, with a a high of only 38 forecast.

Just the threat of snow has wreaked havoc on travelers arriving to and departing from Hartsfield-Jackson International Airport. The white Christmas holiday could test travelers, icing roads and delaying flights. Delta Air Lines announced Friday that it canceled 300 flights out of Atlanta on Christmas Day and warned additional cancellations could follow. Passengers are advised to check their flight status before heading to the airport on Delta and other airlines.
