I was looking at hrs 57, 60 & 63

the freezing line and +10C locations with respect to say Boston were very similar to what it had for us yesterday

http://mag.ncep.noaa...R&prevImage=yes

There could be some BL issues initially for e/se areas...I think further NW it's not much of a concern - though there's less qpf so it's sort of a trade off. NAM is definitely the warmest/wettest.

We'll see what the 12z suite brings but I think advisory type snows are not out of the question for some spots.

I'm preparing for a surging sense of excitement to turn into a sick feeling followed by a hallowness that only a pyschoanalyst could explain. bring it!

lol.....The euro made a sizeable jump NW from 12z yesterday, Hopefully we can continue the trend toady on the models, It would suck but would not surprise me that most all storms came NW this winter when you did not want them and when you do want them to they won't

AFTER ANALYSIS OF VARIOUS ENSEMBLE MEMBERS...ALONG WITH OPERATIONAL/

GLOBAL MODEL SUITE...IT APPEARS THAT A LIGHT PRECIPITATION EVENT IS

ON THE HORIZON WITH LIGHT SNOW ACCUMS ACROSS THE AREA BEGINNING

FRIDAY NIGHT AND ENDING SATURDAY MORNING. I CAN FORESEE POPS

INCREASING AS WE NEAR THE EVENT...ESPECIALLY COASTAL AND EASTERN

LOCALES. HIGHEST POPS CLOSER TO POSSIBLE BAROCLINIC ZONE JUST NW OF

SFC LOW AS MID/UPPER LEVEL SHORTWAVE DIGS TOWARD THE AREA.

AGAIN...GOOD MODEL AGREEMENT WITH REGARD TO SFC LOW PRESSURE PASSING

SE OF THE 40/70 BENCHMARK...ALTHOUGH SOME DIFFERENCES EXIST WITH HOW

FAST LOW PRESSURE DEEPENS AND TO WHAT EXTENT.

CANNOT RULE OUT SOME ADVISORY LEVELS SNOW ACCUMS...ESPECIALLY FOR

LONG ISLAND AND PORTIONS OF SRN CT...BUT OVERALL FEEL ANY AMOUNTS

WILL FALL BELOW ADVISORY LEVELS.

kbos soundings... solid 0.39 total qpf

BL warmed a bit, remains borderline throughout

AWF, not the prettiest futility buster

Don't ever doubt my juju in thread making. :snowing:

It snowed last night at home as well.

Honestly I'm not shocked at the better solutions overnight. I think the s/w over the NW was sampled finally and it's having an impact in the overall solutions we're seeing.

You got lucky...Not shocked either, It was discussed in the other thread what could happen if the trough did a little more digging SE

I think the only we ern areas see a bigger bump up is if the low develops a little quicker and combo with pulling the low a hair more west. For central and western areas, you definitely need help on both ends, but it is possible. Lets hope for some good trends here. I won't be around, but want to come home to some white.

Nice trends! Hopefully we can see the trough tighten up a bit more and tick this thing west some.

A lot of people probably don't want to see this go west. Looks marginal for some areas in the BL to begin with.

That's my juju, and don't you go stealing it. I just couldn't stay up to make it to see the snow but it came down in a nice light fashion from what the neighbor was just telling me. All things considered....we're creeping up the scale here. Flurries a few days ago, a bonafide dusting to 1/2" around the area last night, and hopefully a widespread advisory event this weekend. It's not wall to wall HECS, but at least it's snow.

you stole my thread! LOL. Feb 1st start date and I was dogged for it. Lets get this thing amped up and trend NW for a read deal. Scooter in NH smoking cirrus exhaust while home rips?

Bazinga! To all of you for taking the bait.

Not much to add at this point that hasn't already been said.

A little early development, stronger, and a tad west 25-50mi and we're all happy campers.

BOX snippet on weekend system.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
MEDIUM RANGE MODEL SUITE IN PRETTY GOOD AGREEMENT EARLY IN THIS
PERIOD. MORE IMPORTANTLY...THE 00Z OP RUNS OF THE GFS AND ECWMF ARE
COMING TOGETHER FOR THIS WEEKEND/S FORECAST. THE PIECE OF THE POLAR
VORTEX WILL CONTINUE TO ROTATE OUT OF QUEBEC ACROSS NORTHERN NEW
ENGLAND. A RATHER VIGOROUS H5 SHORT WAVE WILL ROTATE AROUND THE
VORTEX...WORKING OFF THE MID ATLC COAST. LOW PRES WILL DEVELOP WELL
S OF NEW ENGLAND. AT THIS POINT...THE MODELS KEEP THE LOW CENTER
OFFSHORE BUT WORK IN A GOOD SLUG OF QPF ACROSS MOST OF THE REGION
DURING SATURDAY INTO SATURDAY NIGHT. LOOKS LIKE WILL SEE AT LEAST
MINOR ACCUMULATIONS MAINLY ACROSS CENTRAL AND EASTERN AREAS...BUT
THIS IS NOT SET IN STONE YET.  WILL CONTINUE TO MONITOR THE MODELS
FOR UPDATES...BUT HAVE NOTED A TREND TO KEEP BRINGING MORE PRECIP
INTO THE REGION WITH EACH RUN.  STAY TUNED.
