Waves of Cold, Snow to Invade Midwest and East Into Next Week

After a weekend with record cold and snow, more waves of cold air and snow are on the way through the middle of November from the Midwest to the East.
A storm last weekend produced the earliest snowfall on record in Columbia, South Carolina, on Saturday. Freezing temperatures settled over much of the South and, when combined with the snow in the southern Appalachians, allowed some ski resorts to open early.
Snow buried part of New England later in the weekend, as the same storm pushed off the coast, turned northward and ramped up.
Another shot of cold air will follow a fast-moving storm forecast to sweep from the Midwest to the East during the second half of the week.
The new storm later this week will not be as strong as the system that hit the Midwest and East this past weekend. However, it will bring spotty rain and snow to parts of the northern Plains Wednesday then the Great Lakes on Thursday.
In the wake of the storm, winds will kick up, bringing in a quick dose of cold air and localized lake-effect snow to parts of the Upper Midwest.
Winds with the cold shot will not be as intense and more from the west in the wake of the storm around the Great Lakes. The northwest flow will bring more lake-effect flurries and snow areas farther east over the Midwest when compared to this past weekend.
As the storm approaches the Northeast on Thursday, it will scoop up some of the drenching rain that hassurged across Texas and the southern Plains. Thursday will be umbrella weather for many areas along the Atlantic coast. Rain could be heavy enough to slow travel for at least part of the day from Atlanta to Raleigh, North Carolina, Washington, D.C., New York City and Boston.
The storm will strengthen over northern New England and neighboring Canada Thursday night into Friday. However, instead of bringing another dose of heavy snow to coastal areas in eastern New England that were hit on Sunday, dry air will sweep in.
Colder air in the wake of the storm will help funnel some Great Lakes moisture toward the central and southern Appalachians in the form of snow showers Thursday night and Friday. Areas from the mountains of North Carolina, eastern Tennessee and West Virginia to western Maryland, Pennsylvania and New York state may receive a small accumulation as rain showers change to snow before ending.
There is a chance the cold air moves in fast enough to bring heavy snow at the tail end of the storm to areas along the Canada border from northwestern Maine to northern upstate New York on Friday.
Indications are that a piece of the polar vortex from the Arctic may break off and move southward across Ontario, Canada, later next week.
According to AccuWeather.com Long Range Expert Paul Pastelok, "The large outbreak of cold air later next will tend to focus over the North Central states, where the lowest temperatures of the fall so far are likely to be recorded."
People will be reaching for the thermostat and heavy coats over the Midwest as a piece of the polar vortex is displaced southward near the United States.
Temperatures later next week may dip into the single digits over parts of the northern Plains and the Upper Midwest.
Much less severe cold will spill across the Appalachians to the Atlantic coast later next week, when compared to the Midwest. However, gusty winds accompanying the cold contribute to another sudden drop in AccuWeather RealFeel® Temperatures in the South and East.
"It is possible freezing temperatures dip toward the upper Gulf coast later next week," Pastelok said.
