More Snow on the Way for Boston!

The city of Boston, as well as surrounding areas, in Eastern Massachusetts have been overwhelmed by feet of snow associated with this last clipper system. Area schools shut down Tuesday, but are set to reopen Wednesday. Transportation is limited with no rail service operating Tuesday and a very limited bus schedule. There are even reports of roofs collapsing due to the impact of heavy snow.

As you can imagine, the very last thing Eastern Massachusetts needs at this point is more snow, even if we are only talking a few inches. 

This next clipper system we are referring to will move in to Western New York early Thursday morning (3-4 a.m. likely), track east through Central New York through the late morning-to-early afternoon hours before pulling into the New England coastal locations by Thursday evening, then lingering into Friday morning. At this time, it looks as if this will be a light to perhaps moderate (1-3″) snow event for much of the Northeast. But there is a kicker and certainly an area of interest we need to monitor. That would be a secondary area of low pressure likely to develop off the Northeast coast in conjunction with the clipper system moving through. This means there could be an area of enhanced snow accumulation if this area of low pressure tracks closer to the coastal region. If it does, it will only yield increased moisture/instability with the already favorable atmospheric dynamics in place. Again for the Coastal region, timing appears to be late Thursday into Friday morning. We are still only talking about light to moderate accumulations with this system. 

Forecast modelDepicted below is our in-house forecast model snow accumulation product which, at this time, is trending light accumulations anywhere between 1-3 inches (2-4 inches at most around the Cape Cod region). But, as with any model, other factors must be considered and closely monitored.  In this case, the track of the coastal low can mean the difference between very light accumulations or very moderate accumulations.

This system looks to be a bit more impressive in terms of atmospheric parameters in place. This system is still several days out so there is still some uncertainty in terms of timing and amounts.
