This will be the difference from south shore. THey are approaching freezing now and you will stay below freezing and ZR until 11 pm.

I wouldn't be sure we always say this kind of stuff and then temps go above freezing quicker than expected. Right now I would expect Northern NYC and north shore to stay frozen through at least 9 and will revisit then.

Temp has risen a degree in the last hour and it’s 28.5. We aren’t spiking 4 degrees in an hour

Not likely but sometimes surface torches fast in these scenarios, however this storm doesn't have a signal for a rapid surface torch so I would probably agree 

Up 0.6 in past 38 minutes to 29.1. Slow crawl. Snow and sleet continues out here

Idk, it’s pretty close here, 3 degrees in 41 minutes, 29 to 32. I’m not too far away from you.

West of the Saktikos and north of the LIE is a different world. We’ll hang on to ZR until at least 10. Check out weather underground map. South shore at or above freezing, north shore and western Suffolk in upper 20s. Usually takes a few hours for the warm air to work it’s way up here

Yea I'd said we'd revisit at 9 and theres no strong warm air push with this, only areas that seem to be above freezing are south shore and southern parts of Brooklyn/Queens. Temps rising less than 1 degree an hour for most of the metro area.

I see, LI climo is quirky. I’m east of the Sagtikos and next to the LIE, neither south or north shore. ZR here still, though I’m now technically above freezing at 32.4, rainfall/snowmelt slowly beginning to accumulate in my PWS’s rain gauge.

29.7 at 9 pm. Another hour and we will start to melt

29.7 here. Many times driving west there is a clear change to colder and snowier around exit 54 on the LIE. And coming from the south once you get about a mile south of the LIE on north. 

I have even seen a big difference between Hauppauge and Commack, where Commack was snowing for hours with 2” down and Hauppauge mixing.

29F Freezing drizzle for last couple of hours.

Everything is iced over good.

turning out to be more icy than i thought it would be..a burst of mod freezing rain, 29.  Icy espically once you're off the main roadways.

This is a good map to visualize the micro climate. Nw Suffolk the cold spot.

Heavy moisture laden snow just came crashing down from my solar panels and shook the whole house. There was no mention of this when they were pitching them to me. If I had been standing on the back patio I would have been flattened. And I was just out there shoveling prior ( a pointless exercise on so many levels but I digress )

I noticed this with the last event, it was slightly colder with more snow when I was in Commack. I finished with 1.2” which was actually less than what ISP got (2.0”), I normally track closely with ISP with snowfall.

Also, I recall last winter when you went subzero while here and ISP bottomed out at +2°, I wonder if elevation/topography plays a role. Does the terminal moraine even rise high enough for a slight cold air damming affect?
