AccuWeather reports a stormy pattern persisting into Thanksgiving will have impact on the busiest cross-country travel week of the year.

More people travel farther during the week of Thanksgiving than any other week of the year, according to the AAA.AAA is projecting that 48.7 million Americans will travel 50 miles or more from home next week.Those hitting the highways or airports early to beat the rush may still encounter some trouble from Mother Nature late this week and this weekend.After pummeling the northern Plains with a snowstorm and blizzard conditions, a storm will reorganize and affect the Great Lakes and Northeast this weekend, according to AccuWeather senior meteorologist Henry Margusity.Initially, rain and warmth will sweep eastward."However, the first true blast of much colder air could bring the first snowfall of the season from the Great Lakes to the central Appalachians during Saturday night and into Sunday," Margusity said.Motorists should be prepared for expanding slippery conditions along Interstate 68, I-79, I-80, I-90 and I-99, as well as the Pennsylvania Turnpike and Southern Tier Expressway Saturday night and Sunday.Even in the absence of a widespread area of heavy snow, bands of lake-effect snow will occur.There is the potential that strong winds could sweep eastward and hinder high-profile vehicles on the highways and cause airline delays from Chicago to Detroit and Pittsburgh and from Washington, D.C., to Philadelphia and New York City spanning Sunday to Monday.
