Explaining the Winter Storm Set-up Taking Aim at NYC Metro! (credit: Meteorologist Josh Cingranelli)
DISCUSSION: Over the course of the next 24 to 48 hours, a winter storm will be developing just offshore from the Delmarva Peninsula as the low pressure system which is currently positioned across the north-central United States gradually travels eastward. As this system finally reaches the East Coast, the low pressure system will fairly quickly re-develop just offshore from the Delmarva Peninsula before turning off to the northeast. At that point, many coastal and semi-interior sections of New Jersey, New York, Connecticut, Rhode Island, and Massachusetts will be experiencing fairly heavy snowfall with blustery conditions in place which will make both ground and air travel very difficult (or even near impossible) at times. This increase in difficulty in regional travel will unfold as the strengthening low pressure system continues to push deeper moisture into coastal sections of the Northeast.
This surge of Atlantic Ocean moisture will be visually apparent by way of multiple mesoscale (i.e., smaller-scale snow bands) coming onshore during the early to mid-morning hours during the day on Thursday. As is often the case, these mesoscale bands will likely be embedded within a large shield of snowfall which will overspread coastal sections of the Northeast over the next 24 to 36 hours or so. Thus, it will most definitely be a slow go of it across immediate coastal and semi-inland sections of New Jersey, New York, Connecticut, Rhode Island, and Massachusetts for many people who are in the path of this incoming winter storm. If you must travel, be sure to leave plenty of extra time if you must go out and about during the heart of this upcoming winter storm.
