I think Northern CT/NW RI also has some ice problems

Yeah I could see a glaze for a little while, in those areas..like your area. Even though we have a retreating high, we have a good CAD signature with snowpack.Take the under in temps across the interior. I don't think it's a classic text book setup for ice, but it has a lot going for it across GC and up through sw NH.

Who is Sam I am?

Scot, what role will elelvation play in this type of set up?

Sam, Wxwatcher.

Elevation usually is key in these setups. I know Will can tell you all about it. In New England, the old "ice stays in the valleys" rule does not usually apply. In sne, the cold wedge is usually deep enough so that the normal rules of thermal profiles still applies for the lower atmosphere....like temperatures decrease as you increase in elevation..etc. You also will have low level ne flow, which will upslope and also force the air to cool adiabatically. That forced upslope flow helps sustain the low level cold area. It may warm to near freezing for a time, but if the low tracks near the canal, I have a hard time seeing you much above freezing.

Yeah I think it's fair. Low goes near the Cape Cod canal and into the Gulf of Maine..perhaps close to the Maine coast. Areas in nw ME could be mostly snow..even down to IZG, on the euro.

Its looking like the Mtns and northern Maine are looking at a warning event, 6-12" is not out of the question up there, I am going to have mixing issues right now here.........

nam 850's trended milder this run. i.e 850's go over 0c before any precip gets here....i.e Tues 5am per NAM.

so nam says NO front end snow thump....has 0c line from SW VT TO Ext. Ne mass.

does have me wondering if icing will be more of a concern .

and why was kev saying earlier the nam trended cooler ...6z took the low over the canal and 0z took it over Bm.....and thicknesses were milder on the 6z and the LLCold wouldn't hold with the low further NW?

the 12z hopefully goes a tick SE then icing could be issue num. 1

also primary is further south this run.

NAM signalling sleet fest but not torch for sure during the event. Sealing the pack with a kiss ftw...

This would be nice for you and I. Some snow, followed by IP perhaps and 34F rain..maybe falling below 32 at the tail end? This was a big change, so we'll see what the rest of the 12z suite does.

The best part, whatever happens to the pack I don't have to watch. I'll be in FL Tues afternoon through Th afternoon..back here Th night. Kind of bummed about the loss of the Friday threat but that may return...

BOS FRH:

Folks ...this is icing W of I-95 given these bolded values:

54012989461 00909 211307 41000100

60058999258 03703 150515 44020401

There would be a weak coastal boundary there with 360 do N drift to the air at probably 29-31F west of that boundary with freezing rain/IP taking place.

Scooter, looks more like FZRA? I am asking Tips says that and the sounds look wet until about 950? , am I missing something?

Yeah the signs of there. Euro has one around d8-9 so the pattern appears to want to develop cyclogenesis at some point.

You're right, it does seem like lots of fzra for some on this run. The cold air may be a bit more entrenched on this run, so it could be more IP for areas further nw.
