The storm arriving in late November is set to bring a variety of impacts, including severe weather, snow accumulation, high winds and the first real blast of winter-like temperatures this season, which could threaten travel as early as Thanksgiving week. Can put in.

The storm is forecast to develop over the Rockies early next week and move northward across the northern Plains and Upper Mississippi Valley on Tuesday and Wednesday.

It will bring some heavy rain and the potential for the first snowfall of the season on the western sides of the storm.

The cold air behind the storm will bring flooding across the Southern Plains and the lower Mississippi Valley, where temperatures are forecast to drop below zero.

There is also a possibility of some frost on the Gulf Coast.

Meanwhile, the storm will intensify as it moves over the Great Lakes from Wednesday through Thursday, bringing the threat of widespread high winds across the Great Lakes and eastern US.

As the center of the storm moves across the Mid-Atlantic and Northeast over the weekend, high winds are expected across Lake Michigan, Lake Erie and Lake Ontario and the potential for heavy snowfall across western Michigan and the Upper Peninsula. Also Western New York.

Snow is possible across the inland Ohio Valley, northern mid-Atlantic, and parts of the interior Northeast through the weekend, although there is still considerable uncertainty in the amount of cold air available for snowfall.

Beyond travel, temperatures are expected to drop across much of the U.S. northern plains and the Northeast quadrant by the weekend, bringing a wintry feel early in the holiday week.
