Well, I would like to see the NAM/GFS/UK come around before getting further excited....but it sounds to me like the EURO is kind of a middle ground.

Going to have to jump on the bus sometime... you're already a day late on updating your hypemeter!!

There actually have been relatively consistent ideas of tracks. Many people are confusing the tracks with the precip shields, but time will bring everything into a clearer picture. This Euro run seems like a very plausible outcome.

Just wondering what piece of the puzzle is the GFS struggling with? Because it has been all over.

The Euro ensemble is coming in slightly east of the op. About 30% are more amplified and result in a farther inland track.

Seems to me like there is more model agreement on the GFS side of the scale. The GEFS seems to becoming the middle ground with the NAM sliding towards it. The UK/GFS OP East and then Euro Ens., Euro OP and finally GGEM leaning East to far West.

Well out to sea. Wow, that's interesting given the trend at 12Z.

To me it looks like a convective mess. Very poor presentation of cyclone formation at the surface that is reflected from failure of low development and organization into the upper levels.

very very messy at H5. think this is a garbage run...

Temperatures are going to plumet tonight!! possbily set a record low, temps are forcasted to get down around -14 possibly lower. NWS was forecasting PC skies tonight but they maybe crystal clear causing possibly even more radational cooling, especially with a 1028MB HP settling in

I can see some places up your way down to -15 or -20, especially in the deeper valleys. The sky should be mostly clear or even totally clear.

Per NWS...I feel like I'm on the edge of a mix or all snow.........won't know until it's here

AIN FOCUS IN THE LONG TERM REMAINS POTENTIAL FOR STORM LATE TUE

NIGHT THROUGH WED NIGHT...WITH MODELS AND ENSEMBLE PREDICTION

SYSTEMS CONTINUING TO DEVELOP A POTENTIALLY SIGNIFICANT EAST COAST

WINTER STORM. BIGGEST CHANGE THIS FORECAST CYCLE IS SLOWING DOWN

OF STORM...HOLDING OFF POTENTIAL EFFECTS UNTIL LATER TUE NIGHT

INTO EARLY WED. OTHERWISE...SOME DIVERGENCE IN THE 06Z RUNS THOUGH

12Z RUNS COME BACK IN LINE. BUT UNCERTAINTIES REMAIN WITH

TIMING...TRACK AND INTENSITY OF UPPER LEVEL AND BOUNDARY LAYER

FEATURES...AS CAN BE EXPECTED 3-4 DAYS OUT. OPERATIONAL ECMWF

KEEPS STORM HUGGING THE MID ATLANTIC COAST...WITH GFS FURTHER

EAST. INITIAL CONDITIONS WILL BE WARMER HEADING INTO THIS

EVENT...WHICH MAY BRING SOME MIXED PRECIP TO FAR SE COUNTIES...BUT

REMAINDER OF CENTRAL PA SHOULD REMAIN ALL SNOW - THE TOUGH PART IS

DETERMINING HOW MUCH. AGAIN...MUCH UNCERTAINTY REMAINS. THOUGH

POTENTIAL FOR A HEAVIER SNOWFALL CONTINUES TO EXIST...LATEST

TRACK/TRENDS BRING A SOMEWHAT LIGHTER SNOWFALL TO THE REGION WITH

THE BEST CHANCES FOR SIG SNOW CONTINUING TO BE IN THE EAST.

CLIPPER FOLLOWS...DROPPING THROUGH THE GREAT LAKES AND SOUTHERN

ONTARIO LATE NEXT WEEK INTO THE WEEKEND BRINGING NW FLOW AND SOME

LIGHER SNOW SNOWERS. WEAKENING YET STUBBORN TROUGH THEN PERSISTS

FOR MUCH OF NEXT WEEK WITH GENERALLY QUIET AND SEASONABLY COOL

WEATHER.
