those watches from mt. holly are weird.  in hunterdon and monmouth county where they have a WSW, the point and click forecast for the those locations are for 3-5" 

meanwhile, they dont have a WSW for middlesex county, but the snow forecast is the same.

 

i assume the criteria for a WSW is the same in all 3 of those counties.

Very odd - one of the strangest I've seen.  Not only that, but NYC office is forecasting 3-7" in the southern portion of their area, which is close to the Philly-NWS counties and no winter weather advisories, even, up for those counties or Middlesex/Somerset and we're certainly within 24 hours of the start of precip, which is usually when they'd want to issue advisories or warnings.

After that Euro run, I can assure you they are coming.

Agreed.  And the Warning criteria up here in Sussex is 7" and doesn't seem like the QPF is enough to get us there (or at least the Southern sections woudl max out).  But the Euro has been steadfast and the short range guidance (esp. the rather solid RGEM) warrant watches in NYC and the rest of NJ, no doubt.

Sussex warning criterion is 6", not 7" (in 12 hrs; it's 8" in 24 hrs).  Given that all the counties in NYC/Philly offices, from Mercer-Middlesex-Monmouth-Bucks-Montgomery on northward have 6" criteria for a warning, I can see not going with the warnings if they don't have enough confidence in 6".  But at least then issue WWAdvisories, as the criterion for all these counties is 3" in 12 hours and surely, we're all going to meet that from 195 up through at least route 80 in PA/NJ/NY.

They won't put out advisories if they are contemplating warnings. Chances are they'll make final decision by 4pm. For mt holly they don't split their counties which may explain why hunterdon got a watch and Middlesex didn't.. all moot anyway because I'm sure they'll all be getting warnings..at least up to morris county

My bad. Thought it was 7". Agreed though. It's absolutely an advisory event.

Is that weatherbell? If so that is terrible, stormvista barely has philly in the 4-6 range because of mixing. Can you verify what source those maps are from?

Hour 24 Philly 850 minus 1. Surface 32. Hour 30 850 minus 2 surface 31. I don't see a big mix issue for u guys.

The early light precip at 18 hr you're at 35. But that's so light most of you're precip is in the 6 to 9 hours

He's very good, I followed him closely when I lived in PA, still follow him now for us.

 

He's a great guy and I've already learned a lot from him. 

 

12z ECMWF has some insane precip rates tomorrow afternoon, which may actually verify just looking at the amount of moisture down south. 

 

SEPA gets hit with 8-12", but I wouldn't be shocked to see 6-8" in the NYC metro.
