Well I'd say NAM is way overjuiced qpf wise but it may have a good idea of low track adjusted (nodded) about 10 miles east to come into synch with other guidance. Big one on the way. Euro I suppose is the way to go and that was a beautiful hit for most.

Yeah, it's a real close call. I have no access to the Euro beyond PSU which I never really use. But looking at the NAM/GFS it's very much the same at 18h they've come totally together.

The GFS still won't spin up that vorticity and as a result it;s east with the QPF.

Go with the EURO like you said.

They had that purple/magenta colored stuff in the grey and the grey covered up here...

I think I was lowered by an inch or 2...

NBD... NAM will prevail

An inch or two difference in a forecast is negligible at this point given the totals we are expecting for ORH county...its going to be a nowcast thing. We could end up with 10-12" or end up with 18-20"...we really won't have many clues as to which until the storm is underway.

I want everyone in bed asleep by 8:00 and up by 2:00-3:00 AM

lol....

I'm going to bed early but after I see NAM/RGEM/GFS/UKMET. The good news....I'm 64 years old...and feel I can give myself tomorrow to enjoy the snow. Alternative arrangements have been made and I'll be home with my daughter who needs child care anyway. Me FTW. Even if the storm duds, I'm home.

Every single model we have is in the same basic agreement right now, I think even the RGEM is right over ACK/up through the elbow.

The NAM is kind of alone I think.

Yeah...Mt. Holly an hour ago, but yeah.....

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...

-- Changed Discussion --THE NAM INITIALIZED BETTER THAN THE GFS OR THE ECMWF WITH THE TROF

OVER THE SE THAT IS SHARPER THAN THE LATTER MODELS HAVE. THE WALLOPS

1C WARMER TEMPS AT 850MB ARE NOT EXTENDING THAT FAR INLAND AS APG

AND IAD 850MB TEMPS ARE AT OR BELOW -4C AND MODEL INITIALIZATION IS

TOO WARM THERE.

BASED ON THE 18Z SURFACE ANALYSIS THE WRF-NMM AND CAN RGEM ARE

VERIFYING THE BEST, THE LOW IS TUCKED INTO THE COAST MUCH CLOSER

THAN EITHER THE ECMWF AND GFS HAVE. THIS IS BASED ON CARGO SHIP

WDD3825 OBSERVATION. THANK-YOU OPC FOR THE INFORMATION ON THAT

MOVING BUOY.

THUS THIS FORECAST PACKAGE WILL BE LEANING MORE TOWARD THE HI RES

MODELS WAYS THAN THE HEMISPHERIC ONES. OF COURSE EVEN LEANING IN

THAT DIRECTION DOES NOT MEAN THAT THEIR PCPN PROCESSES (QPF) WILL

COME TO FRUITION.

Enjoy the storm, Jerry. Hopefully, BOS will experience blizzard conditions at the height of the storm.

From ALY's latest. Nice to see.

HEADLINES WILL REMAIN IN TACT FOR NOW...BUT STAY TUNED FROM

SARATOGA THROUGH GLENS FALLS AND WASHINGTON COUNTY. AVOIDING KNEE

JERK CHANGES JUST A FEW HOURS AFTER ADVISORY ISSUED...EVEN THOUGH

SOME GUIDANCE AND TRENDS IN DATA SUGGEST POSSIBLY CLOSE TO

WARNING CRITERIA. HEADLINES ARE AN AFTERTHOUGHT...THOUGH...AS

4-8" PREDICTION NOW...POSSIBLY UPGRADING TO 5-10" OR 6-12"

LATER...IS STILL A VERY SIMILAR SENSIBLE WEATHER IMPACT. SO...

AGAIN...MAY OR MAY NOT NEED TO UPGRADE HEADLINE FROM SARATOGA

THROUGH GLENS FALLS AND WASHINGTON COUNTY...BUT THAT WILL DEPEND

ON NEWER DATA/GUIDANCE.
