That run had a max temp of 36 here, the 13z has the max temp at 34.

Anything within a few degrees is pretty close in my book since I don’t expect perfection from these models. The general rule of thumb is that warm fronts usually have no problem making it through CNJ. Then they usually hang up somewhere between I-78 and I-80. Long Island usually makes it above 50° but sometimes Central Park can hover in the mid 40s. Usually have to get far enough north closer to your area in order to struggle to get above freezing.

Oh I agree, not looking for perfection but at possible trends.

Yeah, I have noticed that these warm fronts can slow their northward progress to the north of NYC when there is snowcover on the ground. It’s usually models like the HRRR that do best once we get within the shorter term range. Maybe someday they will boost the Euro to 4km or lower and make it more competitive.

Im on that anomaly,something is off or a unforeseen transfer to the coast later is possible. Colder air is rushing behind the primary low which i believe might be dying in eastern ohio/western pa and the trailing energy down in tenn now moving in to va is the new primary. Watch out if the low exits the southern jersey coast,alas northerly winds keep it colder. Cle to buff back to snow currently.

I'm thinking that the cold air damming is a little stronger than had been modeled. It might still get to 50°, but there's a little more uncertainty than there was even 6-12 hours ago.

6 hours ago ..modeled for mid 50's ..recent trend is cooler..we might barely get in to the lower 40s now. The northerly winds continue and temps havent budged much currently.

this is like a minor version of one of those 1993-94 ice storms, that happened quite frequently back then

CoCoRaHs snowfall yesterday, parts of the widespread 1/2-1" qpf the past 24 hours ending about 8AM. I know its less than I anticipated I80-II84 corridor NYC WEST to nw NJ and the Pocs. The icing is making up for it...  Click for clarity if interested.  image.thumb.png.36d8a75a899ca11cf6c806b6b423e919.png

I got about an inch and a half outta the little event up here. It actually snowed more then what was predicted,not by much though.

We have really been lucky closer to the coast that we haven’t had a significant ice storm since 2011 and 2007. Our last major ice storms were in 1994 and 1978. One of the biggest since then was a dangerous glaze one early morning on Long Island with some freezing drizzle that wasn’t really forecast by the models. I don’t  remember the exact date but I think it was a Sunday Morning.

Yeah average sst's were also cooler back then, that actually contributed to the ice storms in the 90's. Now any fetch off the water,its rain. :lol:

We’ve had a good amount of snow the last few weeks with south winds even on the island. I’ve been surprised but wind off the water hasn’t hurt us that bad

I thought 2010-11 was all snow, did we have an ice storm that winter? The February 2011 event maybe-- the one which gave Chicago a blizzard?

I wish the NWS kept track of ice accumulations/accretions, that January 1994 event had to be one of our biggest ever, we had close to 2 inches of ice on everything here in SW Nassau County, JFK, never made it to freezing or above.  Is there an ice total from that storm for JFK? And that was freezing rain on top of sleet on top of snow!

I think we had a major ice storm back in 1973 also but don't remember anything about it.

Well it is also a known fact that the waters around our area are cooler this year as compared to the last few. If the water is in the 30s then yeah it mitigates faster warming. Its like blowing a fan over a ice sheet.
