Bottom line is it is going to be a mess with more frozen the further north and west. Models will continue to waffle on details, but the general idea of a frozen to liquid event is pretty set. The kicker is a sort of wild card, but I am not expecting much substantial.

We've seen this set up ALOT with ptype issues, 84 is usually ALWAYS the battle ground...I expect some of the colder air is a bit underestimated

Still very close call for a lot of interior sections.. Next 2 days should be fun to track

Upton is saying the same in their AFD this morning.

.LONG TERM /MONDAY THROUGH FRIDAY/...

MONDAY THROUGH TUESDAY...HIGH PRESSURE WILL MOVE OFFSHORE ON MONDAY

ALLOWING FOR A RETURN FLOW TO SET UP WITH LOW LEVEL WARM ADVECTION

COMMENCING DURING THE DAY. ALOFT...AMPLIFYING RIDGING ACROSS WESTERN

NORTH AMERICA SENDS SEVERAL PIECES OF ENERGY INTO A DIGGING TROUGH

ACROSS THE CENTRAL STATES. MODELS ARE COMING INTO BETTER GENERAL

AGREEMENT WITH THIS TROUGH...BUT STILL SUBTLE DIFFERENCES IN PHASING

OF ENERGIES REMAINS. THIS IS NOT SURPRISING AS THIS ENERGY IS

EMANATING FROM THE NORTH PACIFIC AND IS COMING ASHORE LATE TODAY

INTO EARLY SUNDAY.

GENERAL AGREEMENT THAT LOW PRESSURE WILL DEVELOP ACROSS THE SOUTHEAST

LATE MONDAY INTO MONDAY NIGHT AS THIS ENERGY AMPLIFIES THE MIDDLE

AND UPPER LEVEL TROUGH. WARM ADVECTION AND INCREASING MOISTURE AHEAD

OF THIS LOW SHOULD ALLOW FOR PRECIPITATION TO BREAK OUT MONDAY

AFTERNOON AND EVENING...WITH THERMAL PROFILES SUPPORTING SNOW. IT IS

AFTER THIS TIME THAT UNCERTAINTY CONTINUES AS THE LOW INTENSIFIES

AND TRACKS ALONG THE COAST OR JUST INLAND TUESDAY. DETERMINISTIC AND

ENSEMBLE MODELS STILL SHOW SPREAD WITH THE TRACK AND INTENSITY OF

THIS LOW PRESSURE MONDAY NIGHT INTO TUESDAY. THIS WILL ULTIMATELY

DETERMINE EXACT THERMAL PROFILES AND HOW MUCH PRECIPITATION WE END

UP SEEING ACROSS THE AREA.

THE SIGNALS ARE THERE FOR A RAPIDLY INTENSIFYING LOW TO MOVE FROM

THE MIDDLE ATLANTIC REGION TUESDAY MORNING TO NORTHERN NEW ENGLAND

AND SE CANADA BY TUESDAY NIGHT. HAVE FOLLOWED A CONSENSUS FORECAST

DUE TO THE REMAINING MODEL SPREAD ON THE TIMING/TRACK/INTENSITY OF

THIS LOW...BUT HAVE INCREASED POPS TO CATEGORICAL MON NIGHT INTO TUE

BASED ON SOME CONVERGENCE IN TIMING OF SOLUTIONS AND ENSEMBLE

PROBABILITIES FOR GREATER THAN .05 INCHES QPF DURING THIS TIME.

Early call would be 1-3" front end dump city, 3-5 NW burbs, 4-7 extreme NW burbs, and 8+" beyond that as you get up north and west of ulster and Sullivan, specifically westwards

 

Anyone N of 84 should watch this.. Its too close to call. Im loving the MSV area to get smoked though. Sullivan county is long over due

Albany's take this far-

SIGNIFICANT WINTER STORM WITH HEAVY PRECIPITATION AND STRONG

WINDS MAY IMPACT THE AREA FROM LATE MONDAY THROUGH TUESDAY. A

WINTRY MIX OF SNOW...SLEET AND OR FREEZING RAIN IS EXPECTED AT THE

ONSET...ALTHOUGH WARMER AIR COULD CHANGE FROZEN PRECIPITATION TO

RAIN BY TUESDAY MORNING. THERE IS STILL CONSIDERABLE UNCERTAINTY

REGARDING EXACT PRECIPITATION TYPES AND AMOUNTS...WHICH WILL

ULTIMATELY DEPEND ON THE EXACT TRACK OF THIS STORM SYSTEM.

Yep..story of the season so far. 12z Euro comes west from 0z. 

It worked out for us with the 2 big snows which came NW right

until model time. 

All winter it comes to the party late and follows the other models. It will probaly  be the same on Sunday and come east

The long range part of the AFD was not updated at 9:30 am - that part was written at 4:30 am and has not changed.  Need to click on "highlight changed discussion" to see what part is new (usually just the short term/near term get updated).

The Euro's east, it's west...always best when one person does the pbp.  Anyway, people have been down on the Euro because it "missed" the blizzard.  Remember, it was the model that very consistently had the storm/blizzard for days before, but just failed to catch on to the northward shift at the end (but did catch it the night before), so it wasn't a complete miss - NAM schooled all the models at the end on that one.  Plus, iirc, the Euro nailed these last two "events" pretty well that had advisories for NYC and eastern NJ, with neither verifying.  So, maybe it's right despite being the furthest west (won't be the first time and it's still the best model).  System won't be on shore until tonight, so tonight's runs will be really important, as we all know how critical initial condition accuracy is with chaotic systems like the weather.

There never seemed to be much hope for this as a true snow maker and I'm quickly losing interest today for there to be any hope.

Front end snow, freezing rain to rain.It's been the identity of this storm all along and it's how it shall be.

It is, what it is.

Nothing like being too far west and north all season, then being too far south and east lmao... Ahhh good stuff
