Mother Nature is about to serve up some unappetizing conditions for the millions of Thanksgiving travelers: sloppy weather, snow, the coldest temperatures since February and a potentially disruptive storm are on the way through the holiday weekend. Here’s a day-by-day look at what to expect this week.

Lake-effect snow continued to fall on parts of western New York that were already blanketed with a foot or more over the past four days. By Monday morning, the village of Cassadaga, east of Lake Erie, recorded 5.5 feet (1.7 meters) of snow. And snow was expected to continue through Tuesday in the largely rural area south of Buffalo.
