Combined with the fact the we'll be going towards a more +PNA and MJO in more favorable phases and -AO and -EPO (not huge negatives but negatives)  based on this and that it is not just the GFS I'd have to say this is the best CHANCE at SOMETHING so far this season.  Just have to see if trends hold.  We're quite a ways away and nothing in this time frame has held so far this season so there is reason for caution.  At least some of interest.  Better than continuous torching.

Jan 15-20 is the most favored time for snowfall climatologically too.

wow I've never heard of this event....was it rain in the city and south shore in Nassau county?

 

This was the first of three events that occurred that week.  The third event was the January 20th snowstorm that dumped 12-18” unexpected inches across the area.  This 1/15 event changed to freezing rain across much of LI away from the south shore and east end.  The north shore was particularly hard hit.

I think it was ice on the Nassau County south shore.  I was a young grade schooler and I still remember the a) astonishment of my parents and all the other adults, and b) how wild everything looked.  As I recall, school was in session, unless somehow I'm remembering the following day, though everything definitely was still ice encrusted.    It took a lot to close school back then.  I see JFK wasn't above 28 that day, and didn't get above freezing until the afternoon of the 17th, which would support the south shore being part of this event.

You actually don’t have to travel to Canada to get pictures with 2” of ice.  I took this on 1/16/78 at my then home in East Northport.

This is the first time that NYC averaged over 50° for the first 5 days of January. The departure was +17.5 even against the warmer 1991-2020 climate normals. So a record warm start to Janaury.

Morning thoughts…

Light rain will end. Clouds could break during the afternoon. High temperatures will reach the upper 40s and lower 50s in most areas.  Likely high temperatures around the region include:

New York City (Central Park): 47°

Newark: 50°

Philadelphia: 50°

A dry weekend lies ahead.

Normals:

New York City: 30-Year: 39.9°; 15-Year: 40.8°

Newark: 30-Year: 40.3°; 15-Year: 41.5°

Philadelphia: 30-Year: 41.7°; 15-Year: 42.7°

Records:

Highs

EWR: 72 (2007)
NYC: 72 (2007)
LGA: 72 (2007)
JFK:  71 (2007)
PHL: 73 (2007)

Lows: also see records in 1910

NYC:  -2 (1896)
PHL: 4 (1896)
EWR: 6 (2018)
JFK: 7 (2018)
LGA: 8 (2018)

I remember both 2007 and 2018 really well.

And in 1996 we had a blizzard on the same day didn't we?

Amazing that all the official stations got to 70+ 11 years after that blizzard....and another 11 years after that we were all hitting record lows too.

11 year cycle again lol? 1996....2007....2018

omg I wonder if that was actually our biggest ice event-- bigger than Jan 1994?

The wild looking scenery makes everything surreal.

That's in celsius correct?

 

Lee Goldberg was talking about the Pacific overwhelming the pattern after the 17th-- so whatever snow we get it had better happen between the 13th-15th.

Overnight, not much has changed from my initial thinking concerning the potential January 13-15 snowfall.

The overall pattern is not consistent with those that have seen big snowfalls based on the forecast teleconnections. There remains a moderate probability that New York City will see a measurable snowfall. The probability of a large (10" or more) snowfall remains very low. Given the timeframe involved, things can change.

Below is recent data from the EPS ensembles for New York City:

Someone said JFK had a high of 28, so I guess my part of SW Nassau also stayed below freezing-- I see that happen a lot, it was also the case in Jan 1994 and the VD 2007 storm....JFK to Oceanside stayed below freezing and when you got further east to Freeport it was above freezing lol.

Same kind of pattern in the March 1993 snowstorm-- JFK had 11" (actually more than NYC), Oceanside had 10" and then it dropped off to Massapequa where only 6" fell.

Don more of a risk of a cutter or out to sea?

I could see a storm that tracks offshore that gives us a few inches (those seem to be rare but do happen from time to time.)
