Radar looks great upstream..we'll start as rain and flip to moderate snow for a few hrs. If Messenger was here he'd be naked to the RUC stroking and smoking

You have a shot a a little it looks like. looks like you end up on the far western edge of that precip. Good place to be. Temps continue dropping steadily here.

still a chance even for you! From kalb

STRONG FRONTOGENESIS AND SOME CONVECTION

OFFSHORE THE DELMARVA SIGNALING DECENT UPPER DYNAMICS AND

FORCING...SO EVEN THOUGH GOING CHANCES IN WESTERN NEW

ENGLAND...AND MOST OF ANY HEAVIER AND MORE WIDESPREAD

PRECIPITATION SHOULD BE FURTHER EAST...CONDITIONS WILL BE

MONITORED FOR A QUICK BURST OF SNOW THIS EVENING AS THE

PRECIPITATION DEVELOPS AND EXITS.

1-2 inches seems a good bet for hilly terrain from CT up thru ORH and maybe as far east 495..

Very disappointing long term from BOX..all models showing accumulating snow Friday and they go with light snow showers? Man do we miss Ekster and Walt

I agree, but think it's confined to ORH co points west.

I agree with BOX's long term approach.....not sure why they would go with anything more than a mention of snow showers, at this point.

It's a mess.

There isn't a model out there that gives anyone in SNE just snow showers..it's not an accurate model discussion

So let me get this straight, you want to follow the OP models, verbatim at this lead time.....after what just happened at 48 hrs with respect to this last event.....great.

The OPs are nothing more than another ensemble right now, like Will said.....the safe approach is to build up from snshrs, as needed.

Well they're not going to bang the gong yet. I've been enjoying ALB's discussions lately. They seem detailed and well structured. This area really is in no-man's land between the two offices. Andy does very well with the Berks so I try to follow his forecasts around the times of interest.

This is probably the most accurate depiction of the 12z model runs I've read. The weenieism on this board (well, from you) is a little over the top today.

THURSDAY NIGHT THROUGH SATURDAY...THE NEXT SERIES OF INTENSE

NORTHERN STREAM SHORT WAVE DISTURBANCES APPROACH FROM THE WEST. AN

ANOMALOUSLY DEEP LONG WAVE TROUGH NEAR 500 DM DEVELOPS ACROSS THE

EASTERN CONUS AS A BLOCKING RIDGE DEVELOPS NEAR GREENLAND. MEANWHILE

PACIFIC AND SUBTROPICAL JET STREAM ENERGY WILL BE TRACKING QUICKLY

EAST TO THE SOUTHEAST OR MID ATLANTIC COAST. LATEST OPERATIONAL

MODEL RUNS AND GLOBAL ENSEMBLES ARE INDICATING A MORE

PROGRESSIVE/SUPPRESSED SCENARIO WITH NORTHERN AND SOUTHERN JET

STREAM PHASING OCCURRING LATER...AS THE POLAR JET STREAM REMAINS

PROMINENT. THIS WOULD FAVOR PERHAPS A COLD FROPA FRIDAY NIGHT

FOLLOWED BY A POTENTIAL NORLUN/INVERTED TROUGH SCENARIO FOR SATURDAY

WHICH COULD BE A CLOSE CALL FOR THE AREA DEPENDING ON THE LOCATION

OF THE MEAN TROUGH AXIS. THERE IS STILL THE 12Z ECMWF AND ENSEMBLE

PERTURBATIONS WHICH FAVOR EARLIER PHASING WHICH WOULD TRANSLATE TO

A MORE SIGNIFICANT SNOW POTENTIAL FOR THE AREA...SO WILL CONTINUE TO

MONITOR IN LATER FORECASTS. FOR NOW WILL CONTINUE WITH CHANCE POPS

THURSDAY NIGHT INTO SATURDAY. HIGHER CONFIDENCE IN COLDER AIR

FILTERING ACROSS THE AREA OVER THE WEEKEND.

Radar would need to start lighting up a little bit more and a bit farther SW but anything is possible.

Every met(except you) on the board is saying it's likely SNE has accumulating snow and at least advisory snow..and you're mentoning snow flurries. I mean get with it

And did you even read the AFD? It's a pretty fair and good assesment of what's going on.

Relying on a big snowstorm (or even likely POPs) from a 120 hour norlun/inverted trough scenario on an op model is pretty dumb.
