There are two March snowfall peaks. The larger one is from March 1st to 10th when most of the heaviest snow has fallen in the 1991-2020 climate normals period. There is a smaller but still significant period from March 13th to 21st. So it looks like we will miss the first interval in early March. But the models are hinting that it could snow here during the 13th to 21st period.There is a very sharp fall off in snowfall after the 21st. 
 

Heaviest March snowfall days at ISP from 1991 to 2020

3-1….11.7

3-2…22.7

3-3….6.3

3-5….7.4

3-7….10.0

3-8….7.9

3-10…6.1

 

3-13…14.4

3-15….7.8

3-16….6.5

3-21….17.5

Chris, what do you think of the early April peak?  There are two April snowstorms that would make the top 10 March list too.  I find April snowstorms to be more memorable than what I've seen in March.  Does the early April peak result in major snowstorms like either of the March peaks (4"+)? Let's use the airports as a base.

It’s not anything like the two snowfall peaks in March. So I am not sure we can really call it a peak. There have only been 3 years with widespread 4”+ amounts in April since 1991. The 3 years were 1996, 2003, and 2018. The one common denominator between those years are seasonal snowfall totals in excess of 50” in spots around the area. So a reflection of seasons with extraordinary snowfall output. 

2018 stands out because it was an extreme backloaded season while the others were snowy throughout.

I figured you'd say April 1982 stands out too because how cold and snowy that storm was, as great as any of the top 10 in March.

I was just looking at the 1991-2020 climate normals period. The April 1982 blizzard was probably a 100 year event. We haven’t seen true blizzard conditions  and record cold combined in April since then. Almost like a leftover from the Little Ice Age like the 76-77 record cold winter. That was right around the time our warming began to really accelerate.

Indeed-- I strongly believe April 1982 was more rare than March 1993 was and more historic too as well as more rare and historic than Sandy was.  Do you find the October 2011 event to be equally as rare and historic?

I would…1982, 1976-2002 April heat…January 2011 February 2010 snows…

Sandy has by far the highest reoccurrence rate of any of the above at 1-600 years. The others are probably closer to 1-100 years. 
what I would love to see is a repeat of the March 1993 event triple phaser displaced 100 miles to the east. That would be our all time snow event

Thanks.  People should respect how great April 1982 was in that it would almost make the list of Top 10 March snowfalls too!  And the April 1910 storm (I hope I have the year right?) would be in the top 10 too.

I should remember this storm

..6.9" 3/8-9/1984

But I do not.... all snow?

And I definitely dont remember this

..8.6" 3/5/1981

too young, April 1982 which happened the following year was my first snowfall memory.

Cooler air started pushing into the region following passage of a strong cold front early this morning. In the Southeast, there was near record and record warmth. At Atlanta, the temperature reached 80°, which tied the record set in 1992. At Charlotte, the mercury reached 85°, which broke the old record of 84° from 1976. That was also Charlotte's earliest 85° or above temperature on record.

Tomorrow will be fair but unseasonably cold. Temperatures will likely start in the teens outside the major cities of the northern Middle Atlantic region and lower 20s elsewhere and then recover to only the middle and upper 30s.

However, a sharp rebound in temperatures is likely on Sunday. Sunday and Monday could provide an early preview of springlike readings across much of the region. Afterward, readings could cool, but remain above seasonable levels until after March 10th. Then, there is growing model consensus that a noticeably colder pattern could develop. The development and duration of such a pattern remain somewhat uncertain.

Overall, March will likely be warmer than normal. There may also be one or two opportunities for at least some measurable snow in the northern Middle Atlantic and southern New England areas.

The ENSO Region 1+2 anomaly was -1.5°C and the Region 3.4 anomaly was -0.8°C for the week centered around February 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.08°C and the ENSO Region 3.4 anomaly has averaged -0.70°C. La Niña conditions will likely persist through at least late March.

The SOI was +18.43 today.

The preliminary Arctic Oscillation (AO) was +0.169.

On March 1 the MJO was in Phase 4 at an amplitude of 0.468 (RMM). The February 28-adjusted amplitude was 0.563 (RMM).

Well at least we have a range of dates to focus on....between March 10 to March 20.  Anything after that would likely be insignificant to minor (under 4").  But I think people on here dont care as long as it's something it's considered a snowy pattern.

 

Go back to 1979 and count all the major NYC snowstorms that occurred after 3/15 over that 43 year period, shouldn’t take you long at all. This is why I’m at a loss when I look at all these “great snow pattern coming mid-month (3/15) and beyond”….maybe central and northern New England score? Even among those freak/fluke, anomalous big NYC snowstorms post 3/15 over the last 43 years, almost every single one of them had solid -NAO blocking, which isn’t happening this time around. Not sure what the hype and excitement is about, despite what JB and his followers are saying on twitter
