Holiday Travel Troubles Possible Across Much of the U.S.

State College, Pa. -- November 19, 2007 -- AccuWeather.com reports that a high located in Atlantic Canada will keep the interior Northeast chilly on Monday. By Tuesday, milder air will make its way into the region. A storm will brew in the Mississippi Valley by Wednesday, and it will bring messy weather to the East on the busiest travel day of the year. Drivers should use caution on the roadways.

Showers will dampen parts of the Northeast; however, the I-95 corridor will remain dry. With milder air pushing north over the recently chilled surface of the mid-Atlantic, a fog could develop and cause travel disruptions, especially for air travel.

Rain is in the forecast for cities like Detroit, Chicago, and St. Louis, while cities farther south like Louisville, Memphis, and Houston will have the risk for thunderstorms. On the back edge of the storm, a massive cold air mass will continue to invade farther south and east into the High Plains. Snow will fall from eastern Nebraska and Kansas to Iowa.

Much of Colorado will also receive snow on Wednesday with the arctic air mass in place. The snow, combined with gusty winds and low clouds would make for difficult travel in some important regional hubs like Denver and Kansas City.
