UNDATED (AP) -- The weather has been causing delays at several of the nation's airports, creating a rough start to one of the year's busiest air travel weeks.
Fog this morning in Atlanta has delayed flights by as much as 30 minutes, while wet weather and wind have been cited for delays in Newark, New Jersey, and Philadelphia.
The FAA says flights bound for New York's LaGuardia International Airport and Chicago's O'Hare International Airport were experiencing delays of more than an hour.
The National Weather Service says steady rain in New York could turn to snow. And meteorologists in the Midwest have been watching weather fronts that could bring an onslaught of snow and cold that could snarl air traffic at O'Hare.
Weather wasn't the problem today at Dallas-Fort Worth International Airport, where a disruption in radio communications caused delays this morning of up to an hour.
