Less than an inch for bob Scott Jerry me Phil

My only thought on that was they did the initial map more for areas where they were more confident of the forecast and waited on the other areas until more model data had come in.  I don't fault them for stuff like this.  As has been said numerous times already, this is as difficult a snow forecast as you'll ever see.

Hello to all.. ..Another weekend, another potential snowstorm for Southern New England with the potential for a heavy wet snow, strong to damaging winds and minor to moderate coastal flooding.. ..A Winter Storm Watch is now in effect for Southern New Hampshire and Franklin, Hampshire, Hampden, Worcester, Middlesex and Essex Counties of Massachusetts for 6" or more of snow. This Winter Storm Watch may be expanded further south in future updates.. ..Strong to damaging winds may prompt Wind Advisories for portions of East and South Coastal Massachusetts and the Cape and Islands in future updates.. ..Minor to possibly Moderate Coastal Flooding is possible at the time of high tide along East Coastal Massachusetts including Cape Cod and the Islands.. ..SKYWARN Activation with Ops at NWS Taunton is likely starting either late Saturday Night or early Sunday Morning lasting through the day Sunday.. Another weekend will bring another coastal storm to Southern New England. In the scenario for this weekend, temperatures will be marginal especially along and south of the Mass. Pike for heavy snowfall but along and north of the Mass. Pike, temperatures should be cold enough for snow and it is likely to be a heavy wet snow across portions of the region. A Winter Storm Watch is now in effect for Southern New Hampshire, Franklin, Hampshire, Hampden, Worcester, Middlesex, and Essex Counties of Massachusetts for 6" or more of snow. Some locations could potentially see around a foot of snow depending on the amount of precipitation and the snow to water ratios. South of the Mass. Pike, precipitation will start as snow, change to rain, and then go back to snow. Some accumulation is expected but confidence is low on 6" or more amounts in this area. Model runs have been trending a bit colder and this may necessitate Winter Storm Watches extending further south into portions of Connecticut, Rhode Island and Southeast Massachusetts. This will be monitored closely. The heavy wet snow clinging to trees and power lines may cause scattered tree and wire damage and scattered power outages. The area where this may occur is difficult to pinpoint at this time and will depend on temperature profiles. Strong to damaging winds will be possible across portions of East Coastal Massachusetts and Cape Cod and the Islands as well as the risk of minor to moderate coastal flooding particularly in those areas affected by the blizzard a few weeks ago. Wind Advisories may be required in this area in future updates.

The 12Z NAM looks like it will tip the strengthening trend now

 

Wouldn't call it a trend until it has some support from the rest of the 12z suite, mostly because the NAM has been quite juiced up for several of its last 48 hours worth of runs, and in some cases it's been alone on that.
