Northeast: Frigid Air Lays Ground for Rounds of Snow, Slippery Travel; Rain Likely for Long Island

(NEW YORK) According to the AccuWeather.com Global Weather Center, cold air is building over the Central states will expand toward the East during the balance of the week and will be accompanied by snow and slippery travel in some locations.
Temperatures will be slashed by 20 to 30 degrees compared to the start of this week from the Ohio and Tennessee valleys to the Appalachians. A similar trend has begun along much of the Atlantic Seaboard.
In much of the Appalachians and many areas on the western slopes of the mountains, high temperatures most days will be no better than the 30s.
High temperatures mainly in the 40s during the later part of this week will replace highs in the 60s in New York City, Philadelphia and Washington, D.C. AccuWeather RealFeel® temperatures will plunge into the 20s and 30s at times during the daylight hours.
However, the temperature drops will not be as extreme in the East as they were over the Central states.
The air will get cold enough at night to bring the first freeze to portions of the South, including Atlanta, and the Interstate-95 corridor.
Unlike chilly air episodes thus far this season, this particular cold outbreak will have staying power and is likely to last well into next week.
Bands of snow and flurries have set up downwind of the Great Lakes.
According to AccuWeather Chief Meteorologist Elliot Abrams, “Some areas around the lower Great Lakes that have escaped lake-effect snowfall thus far this season will have their first accumulation.”
Abrams expects enough snow to fall on parts of northeastern Ohio, northwestern Pennsylvania and western New York to make roads slippery.
From Cleveland to Erie, Pennsylvania, and Syracuse and Rochester, New York, lie within this swath of potential rounds of heavy snowfall and slippery travel beginning on Thursday and lasting through the weekend.
A developing storm system along a reinforcing push of cold air will cause some wintry trouble in part of the Northeast Thursday night.
The system will bring a period of snow snow from the mountains of West Virginia and the Poconos of northeastern Pennsylvania to the Catskills of New York and part of New England. A few inches of snow are forecast from interior southwestern New England to southeastern Maine.
There can be slushy travel in this I-95 swath, including some slippery spots in the cities of Hartford, Connecticut, Portland, Maine and Boston before the system moves away Friday morning. The Friday morning commute around Boston could be a difficult one.
Mostly rain is in store from Philadelphia to New York City, but some wet snowflakes can mix in at the tail end Thursday night. Rain is likely to fall on Long Island and Cape Cod.
During Sunday night into Monday night, another wave of cold air will approach with a larger storm tagging along.
While this storm will bring mostly rain to the mid-Atlantic and southeastern New England, it cold air may return fast enough to bring wet snow to the Appalachians and perhapsa change to wet snow before ending to some of the northern and western suburbs of the I-95 cities.
The amount and extent of that snow will depend on the strength of the storm and the speed of the reinforcing surge of cold air. A very weak storm and fast-moving front may translate to only spotty showers of rain and non-accumulating snow for much of the region.
The storm slated for the Northeast Sunday night and Monday will take a cross-country path through the Rockies and Central states this weekend.
