More snow coming for parts of Northeast that have snow on the ground

A strengthening storm is expected to dump snow on interior portions of the Northeast, setting up lake-effect snow that will continue even after the storm departs.
Snow will develop over the middle part of the Mississippi Valley, extend across the central Great Lakes and into part of southern Canada Tuesday and Tuesday night.
This snow accumulated up to a few inches of snow over the northern Plains through Monday night.
At the same time, this storm will send rain showers into the Northeast, with perhaps some wet snow mixing with rain in far northern New England.
A second storm will come into the Northeast from the south, spreading snow across the northern tier of the region.
More snow will spread from the Ohio Valley to New England from Wednesday through Thursday as the second storm catches up to the first storm and becomes a much stronger system as a result.
The potential exists for a swath of significant snow to develop on the storm's colder, northwest flank, which will mostly be in Canada and in northern New England. In these areas, 6-12 inches of accumulation is possible with an AccuWeather Local StormMax™ï¸ of 16 inches.
Colder air will sweep eastward and catch up with lingering moisture during the middle of the week. Farther south, for portions of the eastern Ohio Valley and western slopes of the Appalachians, precipitation will begin as rain Wednesday before changing to snow later in the day.
"Precipitation will change over from rain to snow as the storm and the cold air moves eastward across central New York and northern New England," said AccuWeather Senior Meteorologist Alan Reppert.
This mixing will limit snowfall totals to just a few inches in the central Appalachians, with little or no snow along the coast.
This amount of snow is still enough to cause slippery spots on untreated surfaces from northern Pennsylvania to Vermont, including on portions of Interstates 80, 81, 86, 87 and 91.

The same areas that have been in a snow drought this winter, namely along the I-95 corridor from Connecticut to Maryland, will once again miss out, much to the dismay of snow lovers.
Washington, D.C., has picked up 0.6 of an inch of snow this season. Typically, by this point the nation's capital has received 12.9 inches. Farther north, Philadelphia has recorded just 0.3 of an inch of snow or 2% of normal so far this season and New York City has picked up only 4.8 inches of snow so far this season, a mere 26% of its normal snowfall.
While the storm is not expected to bring heavy snow to this region of the East Coast, but is likely to generate strong winds in this area.

"While the storm during the middle part of the week would bring rain to the coastal Northeast and even a large part of the central Appalachians, it is likely to be an effective wind producer," said AccuWeather Senior Meteorologist Dave Dombek.
Rainfall amounts of 0.5 of an inch to 1 inch are possible on the milder, southern side of the storm Wednesday through Wednesday night.
The gusty winds, bringing the fresh, Arctic air over the Great Lakes, will generate some fierce lake-effect snow behind these storms.
After starting in the western Great Lakes late on Wednesday, the cold air and wind on the backside of the storm will spread lake-effect snow to the eastern Great Lakes. The lake-enhanced snow could continue into the weekend.
"Lake-effect snow can pile up in feet downwind of Lake Ontario with this setting up to be a multi-day event east of Ontario," Reppert said. "Even Lake Erie will have some areas that look to pick up over a foot of snow."
Snowfall totals of this magnitude have been mostly absent so far this winter in the eastern Great Lakes.
As the snow winds down, a lingering chill is expected to close out the month of February.
