BOSTON (CBS) – The trend is our friend, especially if you don’t want snow on Friday.
Over the past 24 hours, the snowfall weather models have been moving down quite aggressively here in southern New England. This is not a big surprise given all the factors that needed to be perfectly matched for significant snow accumulation.

Essentially, our area is on the far northern edge of this storm system. In order for us to have a meaningful and effective accumulation, the colder air must flow in quickly enough while maintaining the intensity of the precipitation on the northern edge of the storm.
In a way, we need to get the needle just right in terms of timing and track, which is typical of a mid to late March snow threat.
The latest data appear to show a much weaker northern extent of the system. The storm in the south actually consumes the energy needed to maintain the intensity on our way, which is also common with some of these “spring-like” systems.
So we are reducing the amount of snow and asking for a less effective event overall.
Thursday afternoon and evening: Light rain comes from the west, becomes steady, light to moderate at sunset.
Thursday 7 p.m. to midnight: Temperatures are dropping and the rain is turning to snow from northwest to southeast. Berkshires changes first between 7pm and 9pm. Most of the central and western mass changes to snow between 8pm and 10pm. Eastern Mass., North of Plymouth, turns to snow between 10:00 PM and 10:00 PM. and midnight.
Friday 12pm to 5am: The colder air is slowly pushing south, bringing snow and a mixture all the way to the south coast. Whatever accumulation of snow we get, it will mainly occur in this time window. At this point, as the northern edges fall apart, the snow generally seems lighter and somewhat scattered.

Friday after 5 a.m.: The storm makes a quick exit into the sea and by dawn most of the precipitation is done. In the late morning and early afternoon, sunshine will appear from west to east.
Widely used coatings up to 2 inches for most of southern New England.
While many areas get almost nothing but dust on the grass, some spots can reach inches in narrow bands.
North-northeast wind gusts will peak between 40 and 50 miles per hour over Plymouth County, Cape Cod and the Isles between midnight and 10 a.m. on Friday.
Elsewhere, winds will peak with gusts between 20 and 40 miles per hour which are closest to the coast.
With temperatures above 50 degrees this weekend and maybe 60 degrees the next week, the snow that accumulates won’t last long. In fact, most of them will be gone by the end of the weekend. After that, there is no more snow in sight and the overall temperatures look pretty mild for a while.
