A low pressure system currently over the upper Midwest will carve a path to the mid- Atlantic before moving off shore and passing to the southeast of New England. As is typical with these storms, rapid strengthening will occur once the system hits the water.
The storms exact path, through not set in stone, looks to take a similar path to the January 6th storm that gave most of eastern Massachusetts a fluffy 10-15 inches of snow. This system doesn't look like it will have as much moisture associated with it, dropping a general 0.35-0.5 inches of precipitation. Once again, surface temps will be quite cold which means our snow to liquid ratio will be on the order of 15:1.
A blizzard watch is currently up for Cape Cod and the extreme southeast portion of Massachusetts. These areas will experience the highest snowfall totals (with some ocean enhancement) as well as winds gusting from 20-40 mph. As such, blizzard criteria will likely be met somewhere in this zone.
All of the major cities along the East Coast will be affected by this system. Washington DC, Baltimore, Philadelphia and New York will receive a good 4-8 inches before all is said and done. As such, you can imagine that travel up and down the coast tomorrow will be heavily impacted.
Snowfall will start towards the end of the evening commute tomorrow night, around 6 or 7 PM. This storm will be a progressive system, much like the January 6th event. Heaviest snowfall will occur overnight with all precipitation clearing the region by mid morning on Wednesday. The timing of the storm will likely cause many school closings and delays. Behind the departing storm, bitter temperatures and a stiff wind will cause lots of blowing snow and dangerous wind chill values. Here are my expected totals below.
