Download RadarScope and use Correlation Coefficient. The yellow line is where sleet mixes in. This was as of a few minutes ago 

Looks the same on CoD site.

When will secondary take over?

12z ICON a good hit for everyone...again, this doesn't carry that much weight, but nice to look at.

[Prue11]

8-12 still seems like a good bet for nyc/li

It really won't take over in the usual sense. The primary will hang on over wv

[EasternLI]

Yeah wow, c'mon RRFS you got this.

[NorthShoreWx]

For however little it's worth, the 12z TT 3k NAM clown map shows easily over 12" on LI.  We'll see how the sleet affects that.

What did they get before that? 12z means thats starting from 7am

But isn’t that based of 12z initialization which makes a little more sense if not ya you’re right

RAP is a bit more in line with reality?

Parts of dc reported 5-6 I saw from X

[EastonSN+]

TWC is saying 3 to 5 more on top of what has already fallen (Jim Cantore said about 3 to 4 in central park so far.

 

[Stormlover74]

But parts of Baltimore county are at 10+ so there will always be winners and losers

[nycsnow]

RGEM is a crush job has the sleet line slower/ pulls south later while over Long Island 10-15 inches

If that starts 7am then yeah. Take an inch off DC. They prolly had half an inch before the sleet. 

[nycsnow]

Clear push south on the sleet line south of  Jersey last few frames..this is gonna be a back and forth battle with this extremely cold atmosphere.

7 degrees, heavy snow in Nazareth PA (75 miles due west of NYC).  Enjoy it today!

Yep, if we can get it to fight back and forth for a while, even an hour that could mean 2 more inches. The radar looks amazing coming out of NJ. The ratios are coming down as the column warms but higher intensity will make up for it then some. That looks like 2”/hr stuff coming.

We are focusing on north to south but west to east is very important. If u look at the models the warm tongue moves northeast not due north. Same down there.

5" in Hazlet Monmouth county.

If you look at kdix mix line you can see that battle happening down there, back and forth

Upton should have stuck to their guns instead of caving to the NAM.

it's a tough call; mt holly laid out their reasons why we could still hold onto snow longer but also saw the sleet. they didn't reduce things that much, really. i still have a tough time believing in the higher amounts here.

Correct. 

[nycsnow]

can see it on klwx as well… there’s a nice fight with the cold air…. Any slow down can be huge @jm1220

[EastonSN+]

The biggest push of sleet will be when the coastal starts to develop. Need to watch for when that starts to develop.
