South Coast of Connecticut looks like it has good chance to receive one to three inches of snow overnight; especially Bridgeport and points east; one caveat is a possible warm push of air between 750 mb and 800 mb.

If that ends up as sleet, which at least some of it should with that warm layer, accumulations would be lower than 1-3 inches, and I'm not so sure if some of the model snow maps take sleet into consideration (although others here probably know about this more than I do). Still, there's a clear trend for this to bring frozen precipitation, apparently accumulating, as far south as NW NJ, southern CT, and Rockland/Westchester counties, which is quite a big change from what the models had 12 hours ago for this. Interesting why the storm changed so much on the models despite being only 1 day away...

I didn't look at any "snow map" to reach my determination...

I was just saying in general that some snow maps posted out there that show 1-3" for southern CT may not be taking into consideration the sleet. Your post didn't mention anything about a snow map and I didn't try to say it did, although my point probably didn't come out clear enough.

Rgem separates snow and ice/sleet.

Curious to see what it shows since it has the best band right over swct and northern NJ this run.

That sounds even further south than the 0z NAM... what a crazy trend, in a matter of 24 hours we've gone from possible 55-60 degrees in NYC to accumulating snow in northern NJ, possibly even getting close to NE NJ.

Just a little radar OBS... the simulated radars on the NAM and CMC did not handle the precipitation near Michigan well, showing it too far south compared to the latest radar. Meanwhile, the precipitation for this storm continues to steadily advance ENE. While the storm is south of what the models had early yesterday morning, I'm wondering if the 0z NAM and CMC perhaps took it a little too far south...

I won't be surprise because in this kind of situation and setup the NAM always has it cold southern bias. I doubt any of NYC and most of LI will see any snow or frozen precipitation except the Northern twin Folks and North shore may see some snow or sleet mixed with the rain. At best for NW NJ especially and Orange County will probably see some light accumulations on colder surface before a change to wintry mix and then rain. NYC will stay on the cool sector tomorrow where it will not get out of the 40's.

It is possible to get some sleet or wet snow for a brief period in NYC but North shore and Eastern LI have better change to see some snow where the aloft is colder. I do think the NAM is taking it too far where RGEM seems a bit more realistic about it. Accumulation should stay north of Tappen Zee bridge, I-80, Southern CT and possibly as far south as the North Folk of LI could even see coating to half inch before changing to sleet and rain. It will be a raw day for NYC where the warm front will get hung in Central NJ near Trenton.
