Discussion
Accumulating snow is likely early tomorrow upon the arrival of the next Arctic air mass as low pressure will form along an incoming frontal boundary zone. Rain will break out later tonight ahead of the Arctic front, but then mix with or change to snow towards daybreak as colder air filters into the region. The threat of snow will be greatest for about a 5 or 6 hour period from its likely beginning in the 5-7 AM time period. I expect accumulations of 1-3 inches in the NYC metro region with isolated higher amounts possible, and while not a significant amount, the timing of the snow will not be great as it will coincide with at least part of the AM rush hour on Thursday. Bitter cold air will flow in behind the system on Thursday night and Friday and then another low pressure system will have to be watched for the early part of the weekend. Currently, that system is more likely to generate accumulating snow to the south and east of the DC-to-Philly-to-NYC corridor with a possible focus on the zone from southeastern Virginia to the Delmarva Peninsula to coastal southern New Jersey…still a close call though.
