The snow event for tonight and Tuesday morning is going to behave about as expected. What was not known was the details, and even at this point some of them are still unknown. What we do know is that a very low water content (about 20:1 snow to water ratio) snowfall will occur tonight and Tuesday morning. This will be the result of a small low pressure area from the west redeveloping just south of New England and intensifying as it moves northeastward into the waters east of New England. As mentioned previously, an inverted trough, or Norlun trough, extending back behind the low pressure area will serve as a belt of instability to enhance the snowfall over far eastern MA and coastal NH, adding to the totals there. The dry\/fluffy nature of the snow will also allow it to add up quickly. The upside of this type of snow is that it is very lightweight and easy to move. Snow accumulations through Tuesday morning are expected to be 2-4 inches from northern RI up through the I-495 belt of MA into south central NH, 4-8 inches east of there through much of eastern MA, but 8-12 inches over outer Cape Cod, eastern Essex County MA including Cape Ann, and the NH Seacoast. In this 8-12 inch area, isolated amounts of 12-15 inches cannot be ruled out. All this should wind down by Tuesday afternoon and clouds will probably break before the day is over.<\/p>\n
Midweek Arctic cold: Still expecting a nice dose of pure Arctic air for Wednesday & Thursday. A weak disturbance will pass south of the region and bring nothing more than a period of high and middle clouds early Thursday, otherwise it will be dry and very cold.<\/p>\n
Late week storm threat: Yes it’s still there. And it’s still too early to provide details, but my best guess is that it will be a Friday night \/ Saturday threat (still some timing issues to be worked out), and threaten the region with a significant snowfall. A few snow showers may linger Sunday depending on the speed of an upper level trough moving through the region. It will be cold, regardless, right through the weekend, though not as cold as at midweek.<\/p>\n
