Always impressive seeing the Great South Bay almost totally frozen over. The Long Beach Super Bowl splash has been postponed to March. I don’t remember that ever happening before. We did it in 2011 when there was still a lot of snow around from the 1/27 storm. 

[Snowlover11]

Low of 8F

[SnoSki14]

Looks a lot more active next week and noticing confluence playing a role and keeping storms from cutting. 

So maybe a lot of redevelopers and SWFEs.

Yeah, this has been the first time since 17-18 and 10-11 that Islip averaged under 35.0° for both December and January.

[EastonSN+]

If the season ended today, this decades CPK average snowfall would be 16.78

This is ahead of the first 6 years of the 70s at 15.85.

This decade is also ahead with 1 above average snowfall season (0 for the first 6 years of the 70s).

The 30 year 70 through 99 average was 21.91. Still behind that by 5.12.
