A storm will slide in from the Midwest to bring another dose of cold rain and accumulating heavy, wet snow to parts of the northeastern United States from Wednesday night into Friday.
Cold air will hold its ground over much of the northeastern U.S. through this week. One batch of cold air will be replaced by another.
The new storm will bring a round or two of rain to Pittsburgh, Washington, D.C., Baltimore, Philadelphia, New York City and Boston.

The air will be cold enough to support snow at the onset of the storm in most areas that received an accumulation this past weekend, according to AccuWeather Senior Meteorologist Brian Wimer.
"From Wednesday night into Thursday night, the storm has the potential to bring more wet snow from parts of upstate New York and northern Pennsylvania to northern New England," Wimer said.
This map shows expected accumulation on grassy and elevated surfaces. Lesser amounts are expected on roadways.
This time, more snow will fall on and accumulate in more places, when compared to the storm this past weekend. This includes some locations in the valleys.
Secondary roads in the highest elevations could become slushy for at time with up to several inches of wet, clinging snow on non-paved areas.
A considerable amount of leaves are still on the trees. In some areas where there is little accumulation on the roads, the clinging nature of the snow on trees can bring down large limbs and power lines. As a result, some secondary roads could be blocked.

A period of wet snow and/or sleet can occur as far south as the mountains of western and northern Pennsylvania to the hills in northwestern New Jersey, the Catskills of eastern New York and the Berkshires of western Massachusetts and northwestern Connecticut. In these locations, any snow or wintry mix will change to all rain later Thursday.

Where snow continues into Friday, accumulations will be the greatest. This most likely in northwestern Maine, northern New Hampshire, northern Vermont and part of the Eastern Townships of Quebec. In some of these locations, snowfall could approach 10 inches (25 centimeters).
It would not be impossible for a few wet snowflakes or a dash of sleet to be mixed in at the onset of the storm from the northern and western suburbs of New York City to Hartford, Connecticut, Providence, Rhode Island, and Boston. If so, this will be the first observed snow of the season for these areas and others.

South of the storm track, from West Virginia to Virginia, Maryland, Delaware and southern New Jersey, a brief warmup can occur and a thunderstorm could accompany the period or two of rain on Thursday.
The combination of rain and fallen leaves can make roads extra slick in absence of any snow in southern areas and intermediate and lower elevations farther north.
The rain, poor visibility and a breeze could lead to travel delays on area highways and at some of the airports in the region.
For upstate New York and New England, the moisture will be another shot in the arm for the prevailing long-term drought. A general 0.25 to 0.50 of an inch of precipitation (rain and melted snow) is likely with local amounts to near 1 inch.
Following the storm into Thursday night, another storm will affect the area from Saturday to Monday.
The storm track will shift farther north beginning this weekend, according to AccuWeather Meteorologist Mike Doll.
"We expect temperatures to average above normal during much of next week," Doll said. "However, toward the middle of November, temperatures are likely to slide back to normal."
By the middle of November, normal high temperatures range from the upper 50s in eastern Virginia to the upper 30s in northern Maine.
