A significant winter storm is affecting travelers over the Thanksgiving weekend, with warnings from Montana to New York and heavy snowfall expected, especially in the Great Lakes region. Up to 42 million people may face travel disruptions, particularly on Black Friday and the busy Sunday following Thanksgiving, where the TSA anticipates screening over 3 million travelers. Chicago could see up to a foot of snow, which may impact major airports, while the Midwest will experience mixed weather with improving conditions by Sunday. The eastern U.S. is forecasted to face below-average temperatures and potential flash flooding in the western Gulf Coast on Saturday.
