    You'd normally need a warm layer above somewhere and it looks like that's unlikely but if we get close enough to the mix line I'd think the possibility may exist.

    Yeah, looks like it'll be CSI related bands across CNY through the ADKs with a little bit of convective instability near the mix line like you said.

    I kept looking for banding signatures on the NW side of the system in mesoscale guidance over the past day or so but any signals seemed to be weak... or maybe I'm just not very good at identifying them. Either way, this stuff means business as I'm at 2" now, so rates are well over 1"/hr under this band.

    I took this closeup of a dendrite a little while ago and thought it was neat how you could see the individual supercooled water droplets that froze on contact. I was worried about the lack of forcing in the low-mid levels but the only effect that seems to be having is preventing the rime from getting significant enough to hamper ratios. Nice event.

    That seems to be where forecast challenges arise since only subtle differences can exist between nonbanded and laterally quasi-stationary band events.  Either way congrats on a nice little event for you guys, light snow just started here.

    Seems like some decent fronto banding going on. It didn't start snowing until about an hour ago but snow growth is good with lots of lightly rimed dendrites so I'm coming up on 1" already.

    Yeah this fits the composite of a laterally quasi-stationary snow band quite nicely, maybe there will be some surprises beneath the band axis.

    AREAS AFFECTED...NRN NJ...SERN NY/WRN LONG ISLAND...SRN VT...SWRN NH...WRN MA/CT CONCERNING...HEAVY SNOW VALID 262326Z - 270530Z BAND OF HEAVY SNOW WITH RATES RANGING FROM 1-2 IN/HR IS FORECAST TO SHIFT WWD OUT OF MA/CT THIS EVENING AND BECOME ALIGNED FROM NRN NJ NWD ACROSS SERN NY AND THE HUDSON RIVER VALLEY INTO PORTIONS OF SRN VT/SWRN NH. FREQUENT GUSTS NEAR 35 MPH WILL LEAD TO BLOWING SNOW WITH VISIBILITY REDUCED TO A QUARTER MILE OR LESS. SURFACE ANALYSIS AT 23Z SHOWED A SURFACE CYCLONE LOCATED SE OF LONG ISLAND...WHICH CONTINUES TO DEEPEN...EVIDENT BY PRESSURE FALLS OF 3 MB/HR. NEEDLESS TO SAY...LARGE-SCALE ASCENT IS QUITE INTENSE...AND HAS PROVIDED A FAVORABLE BACKGROUND ENVIRONMENT FOR HEAVY SNOWFALL FROM THE MID ATLANTIC REGION NWD INTO PORTIONS OF SRN NEW ENGLAND DURING THE AFTERNOON. SNOWFALL RATES ARE CURRENTLY MOST PRONOUNCED NEAR THE JERSEY COAST N-NEWD INTO SRN NY...CT...AND MA...WHERE THE EXIT REGION OF AN INTENSE E-NELY LOW-LEVEL JET /WITH WIND SPEEDS AOA 50 KT/ IS FOCUSING A ZONE OF STRONG CONVERGENCE AND FRONTOGENESIS. DURING THE 00-06Z TIME PERIOD...THE LOW-LEVEL CYCLONE IS FORECAST TO MOVE NWD TOWARD CAPE COD. THIS WILL CAUSE THE ZONE OF STRONGEST MESOSCALE FORCING FOR ASCENT TO BECOME RE-ORIENTED ROUGHLY ALONG A LINE FROM NRN NJ NWD ACROSS SERN NY AND THE HUDSON VALLEY INTO PORTIONS OF SRN VT AND SWRN NH. BANDED HEAVY SNOWFALL WITH HRLY RATES OF 1-2 INCHES WILL BE POSSIBLE OVER THESE AREAS. IN ADDITION...STRONG GRADIENT WIND SPEEDS OVER THE LOWEST HALF KM AGL WILL PROMOTE FREQUENT GUSTS NEAR 35 MPH...LEADING TO POSSIBLE BLIZZARD CONDITIONS. ..GARNER.. 12/26/2010 ATTN...WFO...GYX...BOX...BTV...OKX...ALY...PHI...BGM...

  5. I expect it to make a renewed push up. They had snow in Delmar a half hour ago.

    BGM radar shows better the snow in the western Cats and Poconos etc. ALB radar does a very poor job in that area maybe due to the Catskills peaks wrecking the radar range . Anyway I think the overall pivot nnw will keep up.

    I actually had a flurry here 30 minutes ago until the northwest edge dropped back off. Our only hope for getting in that band to our south is the RUC and thats not a good thing. I know the precip shield is going to push northwest again but i have a feeling this didnt pull toward the coast enough to hit us good. Not to be overly negative but I wouldn't be suprised if we downgrade to advisories and end up with 6" or less.

  6. Thanks and you're all welcome. Enjoy the band when it rocks you. Nothing like 2-4 inch/per snowfall with the winds rippin' and whippin' too. Envy you buggers but my time will come. Remember: Have fun and enjoy!

    could an albany screw job be in the making lol? radar has backed off the approach of the precip and the latest guidance has gone significantly east. oh well at least I was prepared for this ha.
