Nah...just looked GFS is MUCH MUCH warmer. Doubt we see any freezing/frozen precip.

Read this from NWS: http://forecast.weat...1&highlight=off

And CMC is showing a mix.

Agree should be mostly rain.

Also found this interesting

http://forecast.weat...1&highlight=off

.LONG TERM /SATURDAY THROUGH TUESDAY/...THIS PERIOD SHOULD START OFF FAIR AND DRY AS PA WILL BE WITHINHIGH PRES ZONE UNDER CONFLUENT FLOW ALOFT. HOWEVER BY SUNDAYTHINGS START TO LOOK POTENTIALLY INTERESTING AS THE MAJORITY OFTHE MEDIUM RANGE MODELS SHOW A SIGNIFICANT SYNOPTIC WAVE LIFTINGNEWD OUT OF THE GOMEX. THERE IS A LARGE SPREAD WITH THIS SYSTEM ANDTHEREFORE FORECASTER CONFIDENCE IS LOW AND UNCERTAINTY IS HIGH.THE LARGE MODEL SPREAD IS LIKELY DUE AT LEAST IN PART TO THEEVOLVING SPLIT-FLOW PATTERN PROGRESSING FROM WEST TO EAST ACROSSTHE CONUS. THE LONG TERM GRIDS WERE CONSTRUCTED USING A MANUALBLEND WHICH ALLOWED FOR MENTION OF PCPN OVR THE SRN ZONES ON DAY6/SUN GIVING A NOD TO THE ECMWF/NOGAPS DESPITE THE MAJORITY OFTHE GUIDANCE SHOWING A LOW TRACK TO FAR TO THE SOUTH TO IMPACTTHE CWA. THIS SYSTEM DEFINITELY BEARS WATCHING WITH THE POTENTIALFOR SIGNIFICANT WINTRY PCPN NW OF THE LOW TRACK. IT SHOULD ALSO BENOTED THAT THE GFS AND ITS ENSEMBLE MEAN HAVE AT TIMES SHOWN AN ERNBIAS WITH RESPECT TO DEVELOPING EAST COAST STORMS AT LONGERRANGES.

I wouldn't look too far into it, but the 18z NAM is pretty wintry on Thursday for at least the Northern half of the state.

Yea the NAM has pretty consistently been the coldest with this system since its gotten in it's range. Def not out of the question that the central counties could get a thump of snow as the region can have a knack for pulling off a snowfall in a really marginal situation. Seems to have a nice slug of heavier precip too, so could be enough to collapse the column. NAM obviously has a finer resolution to see thermals at a much more local level, but the mid-late range NAM is also an accomplished troller. So we shall see.

I guess I should note that the only major model of the 12z suite that did something differently was the normally really suppressed NOGAPs which took this weekend low from TX to the central lakes. I mean I take the Nogaps mid range handling of this complicated split flow regime about as seriously as someone that told me it was gonna rain purple squirrels..but it didn't bury this system to Bermuda like you'd think it would. And last nights run had about the same thing.
