    12-14" depth here....average is 13.5"

    Down from peak depth of 20-22" (21") two weeks ago.

    8" loss to mostly settling, but some melting of late.

    Ray, Ray, Ray WTF you now have me in the 1-3" ? WMUR mets 3-6" close to their 6"+ line for me, which seems really close? Anyways  good luck on you call, we shall see.

    BVY up to Salem, Manchester-by-the-sea, and Cape Ann could be ground zero. These are fickle so no guarantees, but those spots have done very well before on IVT/Norlun-esque setups. These soundings are excellent too for those near the coast with those steep low level lapse rates being even more enhanced. 

    Should I be concerned about blowing snow "during" the event or after when the arctic air moves in?

    Final Call: High Impact & Long Duration Winter Storm Imminent for Sunday PM Through Monday

    Cancellations Certain Monday & Delays Possible Into Tuesday

    Synoptic Overview

    There has been very little change to the forecast rationale from First Call issued on Thursday. The primary trend amongst guidance earlier this week for the two pieces of energy destined to comprise our storm to phase much earlier than originally forecast.

    This has major implications on the forecast late Sunday into Monday because the earlier phase out in the nation's mid section induces southwest flow aloft over the eastern portion of the country, which induces a moisture-laden, southwest flow in advance of this system raise heights. This not only allows the storm to track further to the north and closer to New England, but it also forces warmer, moist air to flow over top of the arctic dome that will infiltrate the area tomorrow evening, which will enhance precipitation.

    The combination of the polar vortex, -NAO block and 50/50 low to the north that had been previously expected to limit the impact of the storm now merely ensures that it will remain mostly snow, rather than change to rain across a larger portion of the area due to a track much further inland. The latter is normally a risk with a phase this early, but in this instance, the pattern will simply now allow that to occur. 
     

    Expected Storm Evolution

    Snowfall should begin moving into southwestern Connecticut from the tri-state area early Sunday morning.

    It will then rapidly overspread the rest of the area by noon.
     
    AVvXsEgzZaCHv07BhwHGmdi4rCoPhPZLNFFxg3Wk

    Snow should grow heavier fairly quickly throughout the afternoon, as is often the case when abundant moisture overruns an antecedent arctic dome, so travelers returning from Patriot's AFC title game parties should beware of deteriorating road conditions.

    This initial "wall of snow" is likely to be most pronounced in areas south of the Mass pike, as intense frontogensis will gradually subside as the leading edge of the precipitation advances more deeper into the arctic air and confluence.

    More of an onshore flow will develop Sunday evening with the storm making a closer pass, which will cause a coastal front to form over eastern Mass, potentially enhancing snowfall along and immediately poleward of this boundary as a result of increased lift due to the interaction of the marine layer with the arctic air over the interior. 
     
    AVvXsEjRTL4mutwFB5nJxmfPViLfz-OORazbwn_X
     
    Deeper into this marine airmass, snow will mix with and change to rain over at least the outer cape and islands by midnight Sunday night, but not before at least several inches of snow have already fallen.
     
    AVvXsEgYWBmFqJ3tDjbkEMrNjb-DIymz_StKMyx5

     
    Although the initial push of warm air advection snowfall will likely be heavier to the south of the Mass pike, northern locations will play catch up during Monday morning, as the energy from the primary system over upstate New York begins transferring to the developing coastal low passing off of cape cod. The Monday morning commute will be worst from Boston points north, and best over the cape and islands.
     
    AVvXsEi1poLPQIqpK2RxJlq7Ye7skwweGECR6zzI

    Just how prolific and protracted this second phase will be depends on how quickly the redevelopment of the mid level low can occur, which will trigger a deep easterly inflow on the northern side of the system, off of the warmer ocean and over the arctic air in place. It seems as though several more inches are possible across the eastern half of the region.
     
    AVvXsEgculwicQbsXt91HOU3hjHDBQzKQou3VIIJ

     

    This will promote a continuation of snowfall of varying intensities into the deep interior during the afternoon on Monday.
     
    AVvXsEgKz8yWfXk-Q0Lf15lrOGEAbYnfL4e6BD5N

     

    Snowfall should finally taper off by Monday evening, with any residual precipitation ending as snow showers over the cape and islands with colder air rushing back in.
     
    AVvXsEj2573iSz39atWTuhT6tuL-qLipCVAcTLU9

     

    Precipitation should move out by the predawn hours of Tuesday AM, but be prepared for some delays on Tuesday due to the large amounts of snow that will have fallen.
     
    AVvXsEgrW_7IIFy6SLBo6LAHPK35UD4W3KAV3yem

    Thus it would be prudent to also allow for extra time on Tuesday AM.

    Final Call:

    First Call: Issued Thursday at 3pm:

    A+ fantastic call and write up Ray.

    Ended up with around 9 inches at the groomer barn and 10 inches at the house, picked up around 4.5 inches throughout the day yesterday. Ran the groomer over it last night, definitely needs another pass and some sled traffic but should set up by the weekend

    Is that a PistenBully?

    ~12.5’’ new. Rates have let up a bit. Looks like we get one more burst then maybe the stuff in W MA then the dryslot races in. 
     

    Great region-wide storm but somewhat disappointing up this way if we end with like 13-14’’ tonight. Don’t think tomorrow is much more than 1-3’’. Had the rates but got killed by shitty snowgrowth. 

    Dom, haven't had a chance to measure, just pulled into to the shop lot, drifting, blowing off the roof. 11F/ chill @ 4

    1-3" as per some of the mesos for a limited number of SNE/CNE people

    I figured I would break it out so as not to clutter the main thread
