Major storm to unleash snow, heavy rain and wind in eastern U.S. Monday. [View all]
The first powerful winter storm of the season in the East will wind itself up on Monday and plaster the zone from Tennessee and Kentucky to eastern Michigan with snow and wind. Heavy rain and thunderstorms will soak locations just to the east.
The storm will take shape over the Deep South on Sunday, unloading heavy rainfall. Then, it will rapidly gain strength as it sprints from western Tennessee to western New York on Monday.
Snow is expected on the storms cold side, west and northwest of its track. By Tuesday, accumulating snow may have fallen in eastern Michigan, western Pennsylvania, Indiana, Ohio, Kentucky, Tennessee, West Virginia and high elevations in western North Carolina.
Along and to the east of the track, heavy rain is predicted from the Gulf Coast to the Northeast. Strong to severe thunderstorms could also develop in the warm, humid air ahead of the storm from the Southeast on Sunday to the eastern Mid-Atlantic on Monday.
As the storm cranks up Monday, it will turn into a big wind generator, which could cause blowing and drifting snow on the storms cold side. Windy conditions are forecast to linger in the Northeast through Tuesday.
In the storms wake late Monday into Tuesday, some of the coldest air of the season will rush into the Southeast and Mid-Atlantic, a possible preview of a cold, stormy pattern during the first half of December.
After developing near the Louisiana Gulf Coast on Sunday, the storm will draw in cold air as it merges with a disturbance diving south from Canada into the Upper Midwest and Tennessee Valley.
On Monday morning, snow is expected to break out from near Indianapolis into eastern Michigan, including Detroit, before eventually expanding south and east into western and central Ohio and northern Kentucky in the afternoon.
By Monday evening, snow could spread even farther south and east, into eastern Ohio, West Virginia, eastern Kentucky, eastern Tennessee, southwest Virginia and western North Carolina.
Into Tuesday morning, snow will probably infiltrate western New York and western Pennsylvania on the storms backside. Here the snow will be enhanced as cold air passes over the relatively warm Lake Erie.
Models are still coming into focus as to how much snow will fall and where. Both the European and American models suggest the heaviest amounts will focus between Indianapolis, Detroit and Cleveland, with the potential for at least several inches.'>>>
