The storm track for an approaching coastal low pressure system
is beginning to become more clear. At this time it appears as
though this system will pass just south and east of the 40N/70W
benchmark. This will support accumulating snowfall for almost
all of southern New England. At this time it appears as though
the heaviest snowfall will be over southeastern MA. Consulting
mesoscale model guidance a respectable low-level frontogenesis
band extending southwest to northeast is expected to set up
somewhere over The Cape and Islands. We generally expect
heaviest snowfall just to the northwest of these frontogenetic
features. Hence, the expectation that southeastern MA will see
the brunt of this snowfall.
