Where I am I think it’s pretty likely. Dews are in the upper 20s and wind should be about calm. 

Dews are in the mid to upper 30s in our area now.

I saw FRG has 29 dewpoint and ISP 31. I agree they’ll probably tick up overnight. It usually cools down pretty good where I am but I’m elevated 50 feet or so just east of 110.

Yea they are lower than north shore areas I see on local PWS. Uptons point and click has our dews around 35 all night.

DP is 29/30 in Muttontown, should be around freezing tomorrow for the low.

You can tell how fake the cold is, when someone sneezes the temperature jumps up several degrees. 

I was in the upper 40s but a 4 mph wind was recorded and it resulted in temps jumping into the lower 50s.

I grew up in East Northport so I can tell you that the combination of the slightly higher elevations on the north shore and a very light breeze off the sound during the overnight hours messed up many a frost opportunity with this type of synoptic setup.  It’s why places in the center of the island and out by Westhampton are usually the cold spots.

Yep, and some of the earliest winter events before the sound cools down it rains north of 25A but snow south of there.

Absolutely true.

I moved here in Nov 2018 thinking I’d finally cash in on good winters here vs growing up in Long Beach. Then the luck areawide ran out lol (other than 20-21).

Eventually the longer term pattern will change.  It’s well known that the north shore is the place to be on LI during winter storms with the added moisture from the sound entraining into the synoptic scale precipitation bands.  Now the pattern is more like that of 70s/80s with the coastal hugger storm tracks.  I moved out to PA in 2005 and you guys probably got 3x more snow since then through 20/21 than what I saw here.

I'm not far from the water, about a mile and a half. In November 2012 I had 8 inches of paste while LGA recorded 1 inch because of the station being right next to the East River.

Yep. Was 39 now up to 39.8 with a breeze developing. Don’t see us going lower than 37

38 in Muttontown & 40 in Syosset.
