As if the 6 to 12 inches of snow was not enough for portions of New York and Pennsylvania, more snow is coming from the same storm system.
There is plenty of energy and moisture left with the storm and it appears that cold air will hold its ground in the swath stretching from upstate New York to northeastern Pennsylvania, northern New Jersey and southwestern New England.
There is the potential for an additional 6 to 12 inches of snow to fall in part of this rather narrow corridor, which could push snowfall totals to 18 to 24 inches from this storm.
This is a snapshot of the middle of Wednesday night. The snow and thunderstorms will tend sag southward and eastward with time.
Essentially, if you got snow Wednesday morning, you could double what you have on the ground by Thursday morning.
The crazy storm will cause travel delays, power outages and school closings in some areas.
The snow is clinging to trees and the additional weight could bring some of them down, taking power lines with them and blocking secondary roadways. This is especially true as winds pick up later tonight and Thursday morning.

Thunderstorms with hail erupting over the eastern part of the Ohio Valley into the central Appalachians and coastal areas of the southern mid-Atlantic. The storms will affect a heavily populated area and will include the swath from Pittsburgh to near Philadelphia.
Severe Weather Expert Meteorologist Henry Margusity can see how hail from the thunderstorms covers the ground in part of this region.
"The moisture from these thunderstorms being flung to the northeast will help fuel the heavy snow zone," Margusity said.
Snow Could Shift Southward
As we warned you about last week at this time, there is still concern for the snow pressing southward Wednesday night into Thursday.
Caution! There's a chance accumulating snow could expand farther south than this graphic shows.
The storm center will track off the mid-Atlantic coast during this time. As it does, colder air will be drawn in and to the south.
It is possible snow reaches as far south as the West Virginia mountains, northern Maryland, northernmost Virginia, southern Pennsylvania, northern Delaware and southern New Jersey for at time.
The question is will this occur as harmless snow flurries or will it be a burst of heavy snow, as both are possible due to the highly unstable nature of the storm in this sector caused by thunderstorm activity.
The threat of severe weather will shift east into Tuesday night with storms set to erupt from South Dakota to Texas.
More heavy rains and flooding problems in southern Brazil, northern Argentina and eastern Paraguay into Wednesday.
Fall air will erase the record warmth that has been gripping the Northeast, while chilly air is set to charge into the Midwest by week's end.
Temperatures will seem like they are on a roller coaster ride in the Detroit area as we head into the month of October.
Locally damaging thunderstorms may travel across a thousand-mile stretch as a new storm system pushes across the Central states Wednesday through Friday.
Unusually high water temperatures throughout the North Pacific Ocean have brought sightings of uncommon species to the area as well as concerns from researchers about how it could affect native species.
