It's the Euro vs all the other models. The GFS/UKMET/CMC keep the streams separate and the southern low gets suppressed. The Euro is the only one that has a phase and more tucked in low. 

The UKMET not being on board is big...the other 2 routinely bust at 5 days out.   Euro also moving south is telling.

Sometimes the OP Euro gets phase happy with the two streams. Was it in February that it was the only model showing the phase which didn't happen?

it's done that often since the upgrade a couple of years ago.

The EPS backed off just a hair but still has 1"+ for NYC.

compare to 0z though, it's clearly S and E of that run--1 inch barely gets up to I-84 now...was up in VT last night...agree with Wave that this might be another Euro fantasy storm....should know by 12z tomorrow.    Would still get the upper low swinging through to ruin Mother's day though....

If it was the other way around and the GFS was hyping a storm while the Euro had nothing would you still support the GFS over the Euro?

probably not, but in this scenario, the GFS has support from the UKMET and the CMC.    JMA and Euro vs the rest here.

Mount Holly's latest thoughts on the frost:

"Clouds will diminish across the area this evening and then overnight
skies will be clear to partly cloudy. There may be some ci/ac clouds
moving in from the west after midnight. There appears to be a big
enough window for the radiational cooling to allow temperatures to
drop into freeze warning category across Carbon and Monroe counties.
Lighter frost is expected in the adjacent counties so we will have
advisories there. We will issue NPW flags as appropriate. Elsewhere,
patchy frost is possible in srn NJ and the N/W suburbs Philadelphia.
Winds will be light from the W or NW overnight.  Lows will range
from around 30 north and closer to 40 around metro Philadelphia."

 

Upton's thoughts:

"Shortwave currently in eastern Ontario will pivot around the
center and track through the area between 06z and 12z tonight.
BKN-OVC cloud cover may dissipate some this eve with the loss
of heating...but mostly cloudy skies will return overnight as
the shortwave and sfc trough move through. Majority of hi res
models keep the area dry tonight...so have done the same.

Amount of cloud cover tonight is tricky and min temps will be
dependent on this. Lows are expected to range from lower to mid
40s at the coast and mid to upper 30s inland and in the pine
barrens. There could also be patchy frost development in
portions of the Lower Hudson Valley late tonight."

So this weekend looks like it will be cool and rainy. EPS has been signaling a warm up for the following weekend. Million dollar question is what the pattern will be like for Memorial Day weekend?

Ensembles are split between a deepening trough into the Plains vs further East into the Lakes. Whatever ends up happening will have a large impact on our sensible weather.

remember when the euro showed 30's for nyc? last night's low was 47

Yeah, the cold raw 2mT Euro bias we discussed last week around NYC. Too bad the Euro MOS isn't easily available which may correct for it. Almost looks like the model treats NYC as more rural for some reason since the raw 2m's got the freeze yesterday in BGM correct. Same problem with snow cover in the winter with the extreme -10 to -15 lows on occasion in the past.
