Now I watch the dry slot. Looks to me like it will slide ENE from here, probably keeping the IZG area in the steady precip until the low pulls east. Tough to gauge with the poor radar coverage in eastern Vermont.

Yeah you can kind of see the making of it in the ne composite back across NY state.

Shows up on the GFS 850-500 fields too

I guess probably nothing like they are seeing now, but with continued ATL inflow against those hills..likely to squeeze out some snow up that way.

Very happy with my snow forecast so far. I don't even think I'm going to get burned too badly on my guess at the rain/snow line. Portland may just pick up their couple inches in the next hour or so.

I think it was a great forecast. You we're worried about the southern part of Merrimack county reaching warning criteria and you were right. Ended up with 3.5 total and it did sleet for about two hours as well. The revised snow map after CON was dropped from 6.9 down to 2.5 was a good call too.

Man what a sick gradient. Hooksett is not far from Brian. A half inch?? LOL, wow. I figured at least maybe an inch or two, but the lower elevations had trouble without good cold established. Probably would have been better at 1,000ft for sure.

I've seen this happen a few times since I've been up here. I think 2/24/10 was the last one to this extreme. The CAD up here is tough to beat.

Yeah hooksett is the town just south of Bow where I live and that is a sick gradient for sure. .5 to 3.5 within 7 or 8 miles

It seems once you get passed CON, that defintely weakens in general. I was thinking about that exact comment you made a while back yesterday, as I was looking at the terrain maps up there. You can see why the CAD signal is there.

Yeah, I had the same experience. Heavy winter in Hollis, go over the Saco River bridge into Buxton and it was rain with no indication snow had ever fallen.

Same experience in reverse. Heavy, heavy rain until Scarborough and it was suddenly heavy sleet with multiple cars off the side of the turnpike. Nasty mix in downtown Portland.

It really helps the snow depth survive too. It's so hard to torch it in the heart of winter. If we do get one of those rare 50F/50F airmasses it's usually shortlived. Usually it just spikes up to near 40F for a few hours after the cold frontal passage, but wetbulbs crash limiting any melting. I don't think anything beats those deformation bands that rot overhead, but a string of moderate-heavy SWFEs is close. This 8:1 cement has staying power...in fact my water equiv is going to end up close between this and the Halloween storm (19.1" on 1.15").

9:15am 29.9F light snow vis 1 mile. Finally went out and took some measurements 9 1/4". We have had no mixing. Actually a bit of blowing snow too but the 9 1/4" is accurate!

awesome!!! well it poured here all night....with the amount of water we got down here, i thought someone up there was going to get some big totals...i bet it looks amazing with the new, super white snow, stuck on all the trees!!!

8.2" at 1,550ft at the Stowe ski area base...best estimate measurement at the summit is 10" of new on the work road at 3,600ft (wind is blowing solid up top).

We had a brief lull of just flurries but now it is dumping snow again. These are back up to 1"/hr type rates with this band of moisture moving in.
