I'm not seeing much of a different between the 00z and 12z Euro up this way. It may be slightly better. I don't think anything post 18z will amount to much.
Given it's during the day I think salt will make pretty quick work of this outside of the areas in SEMA that get it heavier. Should be done by 4 as well. I have to drive to Littleton, MA tomorrow at noon and I'm not too worried about it.
I don't think he's necessarily wrong. Unless you have a GFS solution with closed off ML lows which I kind of doubt the strongest 850-700mb fgen is going to be over SEMA and it won't even be that strong. I'm not seeing a big ML magic signal for central/nrn CT. Not kiss it goodbye but I wouldn't go watch/warning for KTOL and surrounding areas.
There's lift in the DGZ but it's pretty damn weak unless you take the GFS verbatim. I wouldn't be super enthusiastic about forecasting >10:1 and I wouldn't be surprised if it struggles to accumulate in the March daytime given rates probably won't be too impressive.
I wouldn't blend it into the forecast but I find it interesting that pretty much all the mesos are handling it similarly. Except maybe the RGEM but it must be 5 o'clock somewhere in Canada and the Labatt is flowing.
The HRRR is really not feeling it. That model mostly sucks but highlights the disconnect between the mesos and globals. I'm going to guess the GFS doesn't go thermonuclear at 12z and cans the warning snows to CON but who knows.
It's really all the mesoscales that have this thing trucking along at a faster clip than the globals. The NAM is still a nice thump down in southern SNE but it's done by 18z. Christ the HRRRx is probably broken sun by 3 or 4 o'clock. It has this thing on rails.
Totally objectively speaking it's a pretty tough call for this area. I haven't really looked at the fringe models but Euro/NAM is going to be mostly poorly accumulating light snow that's in and out while the GFS is borderline low-end warning. I'm not sure if the FV3 GFS carries any weight yet but it's much more in the Euro/NAM camp than it's operational big brother. I'd go 1-3'' and minimal impact right now but damn if the GFS wouldn't make me nervous.
