The punches just keep on coming from Old Man Winter. A new storm is poised to impact parts of the South, Midwest and Northeast this weekend and threatens to bring travel and shipping delays, as well as disruptions to outdoor activities.
While this will end up being a warmer storm for many areas from Texas and Arkansas to the I-95 corridor of the mid-Atlantic compared to recent storms, it will bring snow or a wintry mix for a time in some locations and an all-out snowstorm to areas farther north.
The storm will affect the Central states Friday into Saturday and much of the East Saturday into Sunday.
The first stripe of accumulating snow from the storm is most likely to fall over parts of northern Indiana, Ohio and northwestern Pennsylvania, upstate New York, northern New England and neighboring Canada spanning later Friday night into Saturday.
A second stripe of snow may center over part of the Northeast Saturday night into Sunday, as the storm taps into Atlantic moisture and overcomes competing factors and prior issues with dry air.
Cities likely to stay all snow during the event include Cleveland, Syracuse, N.Y., Burlington, Vt., and Portland, Maine.
Most cities in the I-95 corridor of the mid-Atlantic will have a period of snow or a wintry mix at the onset, followed by rain at the height of the storm.
Snow and a wintry mix will fall on Philadelphia Saturday during the Army-Navy Classic. An eventual change to plain rain is forecast in Washington, D.C., Philadelphia and New York City.
However, it could snow heavily late Saturday and Saturday night prior to any change to rain, raising concerns for a period of slippery roads and more significant travel disruptions.
According to Chief Meteorologist Elliot Abrams, "Boston, Hartford, Conn., New York City and the northern Philadelphia suburbs are among the candidates for a period of heavy snow, since the air is likely to be colder for a longer period of time, as opposed to Baltimore and Washington, D.C."
Some cities in the mid-Atlantic have already received more snow this winter compared to all of last winter, including Philadelphia and Wilmington, Del.
According to AccuWeather.com Expert Senior Meteorologist Bernie Rayno, "For many areas in the Midwest and Northeast, this will be the third snowfall or wintry mix in a week counting the storm last weekend and the storm Monday night and Tuesday."
For many areas, this will be the biggest snowfall of the season so far.
The storms are creating major headaches for travelers and have states, cities and townships going through a great deal of ice melting compounds and spending a sizable amount of the winter budget early in the season.
In the South, enough rain can fall in some locations to cause flooding in urban and poor drainage areas. Rain and low ceilings could impact flights at Atlanta and Charlotte.
The storm will come together over the Deep South Friday and head toward a cold high pressure system moving across the Northeast.
"The storm will be preceded by the coldest air of the season so far in parts of the Midwest and Northeast," Rayno said, "The storm itself will attack the cold air, removing much of it, but squeezing out precipitation in the process."
The Arctic air in advance of the storm will also make road surfaces colder, which will cause more snow to stick.
In the wake of the storm this weekend, a mixture of Arctic and Pacific air is forecast to come in, so it may not feel quite as cold as recent days from the Midwest to the East and part of the South.
"The milder air starting next week will allow a break from the wintry precipitation in some areas hit hard, but not everywhere." According to AccuWeather.com Long Range Expert Jack Boston, "Just enough cold air will linger in the northern tier states to allow more storms with snow and wintry mix as the the month progresses."
Large, powerful waves crashed against the sandy shorelines of the East and West coasts this week, stirred by the onset of two tropical storm systems.

As Cristobal loses its tropical characteristics, attention is turning toward the Bay of Campeche for potential development next week.

An outbreak of severe weather, including tornadoes, will evolve on Sunday from the northern and central Plains to part of the Upper Midwest.
