redundant...sorry that's the English major in me.

Is it over by Sunday...say 9:40PM :lol:

I disagree - even kidding. To say it is windy is a distinct characteristic that has a physical nature clearly differentiated by whether or not said wind is accompanied by great quantities of falling snow.

Aside, the English majors always ruin poetic license -

Yeah 850 0C line is right over your fanny. Probably several inches for you before any changeover verbatim.

scott thanks for the reply.

alos is there a sneaky 8h warm layer in the area?

most models give .5 qpf between 1 and 8 pm it seems so it seems like accumulation may vary greatly depending on the oscillation of the 850 0 C unless of course there is a 8H warm layer that is even further north.

this setup seems like a powder keg for new england and forecasters

That polar HP is still NNW of us now (near NY/VT border)

and that anomalous gulf moisture is just racing northward....up thru hatteras now.........bad bad things are gonna happen.

i mean when gulf and atlantic moisture are involved doesn't qpf sometimes over perform.....like a wide spread 1.5-2 QPF for SNE.

with 850 temps modeled pretty consistent......we need that cold air to hang tough and N'rly drainage flow to dominate close to the coast.

i see most forecasts have ORH....N interior mass getting up to 30. So i guess no sharp coastal front.....would think the air would stay low 20's inland....mid 30's other side of front? with a track near cape.

I'm not worried about the extent of QPF. Lots of moisture involved, along with large scale isentropic lift, should yield widespread 0.75"+

Becoming more confident in a 8-12" deal for S NH and N MA with 0.25-0.5" ice accretion across central MA - southwest MA - northern CT

BOX updated my P/C to 2-4 inches in the city before a change-over straight to rain which could be a driving rain in the mid-upper 30s through the night. 2-4 would be more than I expect since I'm just about 4 miles from the coast. Seems possible that 495 belt north of the pike (and maybe even in to 95) could be in for some heavy icing if it's this chilly imby.

Tuesday: Snow before 2pm, then rain and snow. High near 38. East wind between 6 and 13 mph. Chance of precipitation is 100%. New snow accumulation of 2 to 4 inches possible.

Tuesday Night: Rain, mainly before 2am. Low around 33. North wind between 13 and 16 mph. Chance of precipitation is 100%. New rainfall amounts between a half and three quarters of an inch possible.

Wednesday: A chance of rain and snow showers before 10am, then a chance of rain showers. Cloudy, with a high near 41. West wind between 10 and 14 mph. Chance of precipitation is 40%. New precipitation amounts of less than a tenth of an inch possible.

I'm not sure if there is a sneaky warm layer, since I cannot see the vertical profile, but this could be quite the dump for nrn orh county and srn nh.

The general consensus seems to be ice in northern CT, but I can't really find any concrete forecasts. Do you guys think it will be serious stuff?

After how much snow? With what your expecting qpf wise I would say 4-7"?

What do you think for the Merrimack Valley and Rockingham county? 8-12"?

interested to see what Gray does with this. Seems to be consensue for qpf over .5 for up this way and over to Eric. Looking colder so might be all snow. Do they go to warning with afternoon package? I'd say yes, perhaps for 5-9.

I'd guess warnings for all, right to the coast. Make our coastal friends happy. :)

The 5-9" sounds pretty good, too.
