10 degrees in NYC at the onset of the precipitation, pretty cool (no pun intended).

That sleet line is annoying. All the way up to I-80

Through 7 PM Sunday pivotal close up 10:1 already have over 7 inches

Though it looks like 90% of the previous has called by than.

Looking at trends between 6z and 12z it actually cooled slightly.

If you look at hour 90 though heights collapse slightly faster than 6z. Not sure if that's just a timing difference or that the low is actually dragging down heights behind it faster.

Would you go with 540 or 546 line for sleet?

Solid!

This is through hour 84

What major snowstorm doesnt have some sleet in them...On Long Island I got a period of sleet in Jan 1978,96, 2002 and Boxer Day..when not one model had some sleet..its part of the deal

I believe that is the warmest frame.

Ratio maps show about 11 inches in NYC by the time we go to sleet (at hour 83 or so).

I hate using thicknesses for anything related to precip types.. they are good benchmarks but soundings are the way to go

That would be fine. At that point, sleet just encases everything and keeps the snowpack around.

Looks like a flip back to snow as the coastal takes over-amts are lighter with that piece maybe another few inches?

True, but the sleet line is almost always near the 543 line. It's hard to get snow above 544 and usually below 542, you're pretty good in these situations.

If you get 6-10" of snow, an inch or two of sleet, and a couple inches more snow, and you complain, then there's something wrong with you lol

Precip is mostly done by that

It really depends what location you are looking at and at what time stamp you are comparing to.
