Hi all! Our storm will be getting underway this evening, and already has in some areas with some snow/mix falling, especially along and southeast of I-95. This area will expand and intensify during this evening, leading to heaviest precipitation sometime after 10pm, and especially after midnight, until sometime shortly before dawn.
As I have been worried about all along, it appears the intensity of the precipitation and the time of occurrence will be enough to produce some significant snow in much of the area from near Boston, west and north. There is still some uncertainty of where a rain/snow line sets up and oscillates, so amounts I am about to forecast are still subject to change. Here is what I expect from this system, snowfall-wise, through Friday.
Cape Cod & Islands: Nothing (rain) except perhaps a dusting of light snow Friday afternoon.
SE MA: Around 1 inch.
Immediate Boston Area: 1-3 inches with potentially a little more just NW of the city.
I-95 corridor: 2-6 inches with a very slight chance of isolated heavier amounts along and just NW of I-95.
495 belt south of the Mass Pike: 2-6 inches.
495 belt north of the Mass Pike including Worcester Hills: 6-10 inches with locally around a foot in the higher elevations.
NH Seacoast: 2-6 inches, lowest along the immediate shoreline.
Inland southern NH: 4-8 inches except 6-10 inches in the higher elevations of SW NH.
Lakes Region NH: 6-12 inches.
Be back later with a full forecast including an update on this storm and a look at the first weekend of April and beyond. Have a safe evening!
