Some Light Snow Possible Mid Week
Primarily Northern Sections
Synoptic Overview:
On Tuesday, a modest northern stream parcel of energy will emerge out of a split flow and eject over a western-biased PNA ridge, and into the Great Lakes.
This clipper system will then resume more of an east-southeast track around the base of the departing polar vortex that will take it into New York State on Tuesday night.
The system is likely to have limited room for amplification given the combination of cut-off energy over the southwestern CONUS in association with the southern branch, as well as a PNA ridge that is both fairly meager and western biased.
Potential Storm Tracks:
The forecast modest degree of amplification of this clipper system means that it is likely to track at least somewhat to the north of southern New England, rather than bodily through the region, as modeled by the GFS model, which would imply several inches of snowfalls similar to the last storm.
The Canadian guidance tracks the system significantly further to the north, across northern New England, and produces little if any snow across the area.
While the European model represents somewhat of a compromise solution in which the storm tracks just to the north of the area, across southern Vermont and New Hampshire.
This scenario would yield perhaps an inch or two of snow north of the Mass pike and most especially north of route 2, which may represent the most viable solution. The southern track of the GFS is the least preferred outcome at this time.
Stay tuned for an update on Tuesday if necessary.
