Went from suppression to an all timer.

At least as of now, mix line is stalling/ getting pushed back down a bit down south. Better than seeing it fly obv

[BoulderWX]

Moderate snow already in Morristown

Not liking the east northeast winds

Radar looks incredible down south for us

Lt snow on the north shore of Western Nassau

We have an obs thread.

Light snow began here about 4:45.  Currently 8 degrees.  We are  underway.  The floor on this is great.  Nobody should be disappointed.  Heavy rates and bitter cold.  Going to look amazing around here for a solid week.  

So glad this is a daytime event.

Let’s go!

Snow began about 5:20 am in Melville LI

Hoping for a moderate impact.  Zero interest in having a layer of ice upon 6 plus inches of snow 

Thank goodness it’s a Sunday

RRFS drops the mix line again from

Hour 12-14 hopefully it really happens

i mean we're going to get crushed too, don't look at the models, the rain/snow line is way south and we're going to have heavy snow the next 12 hours!

FYP lol

Some of the hi res stuff has the sleet line really struggling to get through LI lately. Hopefully we can pull an RRFS out of a hat. I do think the thump with this one will be impressive regardless.

I’ve been watching it since last night. A lot of them basically make Long Island the battle ground and the mix line goes north south it’s a sight hopefully it keeps showing up

Figure out a way to get a day off and jump on the Acela.

HRRR also ramping up the pre sleet amounts. 

[Brasiluvsnow]

Not sure when it began in New City Rockland County but big flakes falling and the streets are snow covered,,,,,,it's show time guys and gals

Ok boyz and grrrrrllls - as of 6:30 am we have 3/4" of the most exquisite pixie dust snow imaginable otg at 11 frikkin' degrees F!  Let's get a foot or more!  Woke up for a minute at about 4:50 am and snow had just started then.  

[Dan76]

To bad it's not windy there would be some nice drifts with this powder.

It's going to be a fun few hours before the sleet gets here. Could be 2+/hr. Let's hope anyway. I just don't buy that south of White Plains it won't be all sleet for a while. Hopefully I'm wrong.

Positive trends down south. Sleet line keeps getting pushed down/stalling hell of a battle with this cold airmass

This is questionable. See DCA as an example below. At 18z Sun the 18z UKMET shows 7.7" snow accumulation. The ptype is sleet and the sleet line has cleanly crossed the area. By 21z the sleet line has crossed into PA indicating the line was advancing steadily northward. Yet at 27hr the UK snow total on Pivotal increases to 8.9" for DCA and then 10.3", and 10.4" at 30hr and 33hr. Based on this continued snow accumulation when the dominant ptype is clearly not snow, particularly combined with the mismatch between the UKMET snowfall output compared to other models, the claim above seems dubious. Something is not right with the way Pivotal depicts snowfall accumulation for the UKMET.

 

It's what the site claims. You raise a fair point. It's plausible that the while the sounding says sleet at a specific point in time, there are embedded periods of heavier precipitation that flip back to snow during parts of the period. Unfortunately, the exact algorithm used isn't published.

10 here with snow

Borderline heavy snow under this band Nassau Suffolk border
