A series of storms across the nation are threatening to make Christmas travel a mess.  Thunderstorms across the south, rain in in the east and snowstorms around the Great Lakes could bring serious flight delays and dangerous road conditions.

Up to three inches of snow is predicted for the areas around Chicago’s O’Hare and Midway International airports.  Delays and cancellations at two of the nation’s biggest Midwest airports would have repercussions throughout the country.

“I’d be nervous about the possibility of not being able to get out,” Chicago area meteorologist Charles Mott told the Associated Press. “I would definitely make plans about possibly staying put or doing something else.”

Over 4.2 million travelers are expected to go through the Chicago airports during the Christmas season.

Storms across the Rockies caused blowing snow that blocked major highways and even Hawaii is feeling the winter punch as a blizzard warning was issued for the summits of Mauna Kea and Mauna Loa on the Big Island.  While snow is common, a blizzard is considered unusual by meteorologists.
