I was actually meaning to have this up last night, but I had some technical difficulties. Anyway, moderate snowfall still looks likely for southern New England. Model guidance has backed off QPF to some extent to the northwest, which is a common adjustment in fact. We may be looking at a fairly sharp cutoff to accumulations. However, Keene should be able to rack up a couple inches tonight. GFS is still east of the NAM, however general consensus brings the low just outside the benchmark. NAM continues to deepen low pressure more than any other guidance east of Cape Cod, and I think we could see a decent band set up with the cold conveyor belt in eastern Massachusetts later tonight. This is where I am expecting maximum totals on the order of 4 to 7 inches.
Rain on radar has spread across southern New England this morning, although much of this is virga for the time being. As the column saturates, light rain will develop and fall through the afternoon. The interior should start to see some flakes mixing in by 3pm, and Keene should be over to all snow by 5pm.
The NWS in Taunton has issued winter weather advisories for all of MA, northern CT, and RI, away from the coast. I think they may have to expand at least into eastern Hillsborough in later shifts.
Final call for Keene: 2" to 3.5"

A major storm is becoming more likely for the middle of next week. I will post more details later today. Stay tuned!
