More and more signs are pointing toward a major storm along much of the Atlantic Seaboard next week, meaning a wind-whipped snow for some areas and wind-driven rain for others.
The storm could rank right up there with the Christmas Weekend Blizzard and could hit part of the same area, or different areas farther inland. No matter what, it looks like a "big deal."
While the storm will have its nasty moments over the Rockies, Plains and part of the Midwest this weekend into early next week, it will be at its worst along the Atlantic Seaboard, where it is forecast to markedly strengthen. Arctic air building into the Northeast will also be a major factor in the big storm that will unfold.
The key for what the weather will be in your area is the exact track of the storm.
A track along or just inland of the coast would bring rain over the eastern Carolinas and even a wintry mix into the I-95 corridor of the mid-Atlantic. This track would dump heavy snow, perhaps on the order of 1 to 2 feet, over the Appalachians. Snowfall rates would be intense with perhaps 1 to 3 inches per hour.
A track just off the coast would bring the heaviest snow to the I-95 cities and the beaches, as we have seen before, thus sparing the Appalachians the worst.
It is also possible the storm could swing out off the southern Atlantic coast, then hook back in over the Northeast with a more complex precipitation pattern.
No matter which way the storm tracks, it looks like big trouble for the Atlantic Seaboard next week, not only for the U.S., but all the way to Atlantic Canada.

What Will the Storm Bring to Me?
In the worst-case scenario, which may not be that far on the extreme end with this storm, an all-out blizzard may hit some inland areas, while a period of strong onshore winds could lead to coastal flooding.
If some places get heavy rain on top of the thick blanket of snow on the ground, everything from urban flooding to roof collapses could occur.
No matter what the storm brings to various locations along the Atlantic Seaboard next week, it will lead to major travel disruptions, closed schools, blown budgets and perhaps life-threatening conditions.
The storm has the potential to shut down some major highways and ground flights, stranding motorists on the road and airline passengers at airports.
The storm promises to be potent due to plenty of moisture and energy from a lingering large temperature contrast. The excess moisture slamming into the cold sea of air in the Northeast will yield intense precipitation.
A storm rolling southeastward along the Rockies this weekend will dip toward the Gulf of Mexico early next week. As it does, it will grab moisture from the relatively warm waters.
A temperature contrast from northwest to southeast will help provide the energy for a big storm in the East next week. An example of this contrast is the range in temperatures on Friday with a low of minus 46 degrees in northern Minnesota to a high in the lower 80s in South Florida.
Meanwhile, the coldest air of the season so far will be parked over the Northeast, including many subzero low temperatures in northern New England.
It appears the jet stream, which is a river of air high in the atmosphere that guides weather systems along, will bend, allowing the storm to track up along or just offshore of the Atlantic Seaboard during the middle of next week.

An unusually strong push of cool air for early September will move southward along the Atlantic Seaboard into the Labor Day weekend, before July-like heat returns by next week.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Nino.
After heat has dominated headlines this summer, cool air has finally taken control of the northern half of Europe with no signs of departing anytime soon.
Steering winds could take Ignacio, as a remnant storm, into the southeastern arm of Alaska or British Columbia during the middle days of next week.
While Tropical Storm Kevin will stay well away from Mexico, its moisture will still lead to an increase in showers and thunderstorms from Baja California to the Four Corners region of the United States.
A stormy weather pattern will prevail through September across much of southern South America.
