Winter 2013-2014

[Rainshadow]

Upton has been clocked by a few storms that just missed NYC. Almost a little further east than one would think, but the central part of LI almost has a second max thanks to Miller Bs exiting stage right.

 

Yes its like being at the right place and the right time at the right phase of the storm. 

[Guest Pamela]

William,

 

That Upton average really stands out.

 

...the Upton mean after 65 years is 31.67"...<see link>...

 

However, Upton has seen more than 60 inches of snow 5 times in the last 13 years,  more than 50 inches of snow 7 times in that span and more than 40 inches 8 times in the last 13 years.

Here's a nice write up on snowfall patterns on the Island per board member North Shore Wx..

 

 

http://northshorewx.com/Climate.asp

 

 

Since March 2009, I believe Upton has seen 8 snowstorms of greater than 10 inches:

 

3/2/09: 14.0"

12/19/09: 26.3"

2/10/10: 13.4"

2/25/10: 10.4"

12/26/10: 18.8"

1/11/11: 14.1"

1/27/11: 13.3

2/8/13: 30.9"

2010 was amazing...4 MECS or greater events (1 HECS, 25").

 

Since March 2009 here are the big storms, 10" or greater, we've seen in Dobbs Ferry:

3/2/09: 10"

2/10/10: 12.5"

2/25/10: 26"

12/26/10: 13"

1/12/11: 14.5"

1/27/11: 13.5"

10/29/11: 10"

2/8/13: 17"

 

Five winters have produced eight events of 10"+, which is fantastic. Six of those eight events had over a foot of snow, with the largest the 26" in the Snowicane of late February 2010...that February had close to 50" fall, followed by 40" falling in January 2011. 

 

Here are some honorable mentions that dropped at least 8" of snow, but didn't make the 10" benchmark. 

12/19/08: 8"

12/19/09: 8"

2/24/11: 8"

11/7/12: 8.5"

3/8/13: 9"

 

In five winters, we've seen another 5 events in the 8-10" range, bringing the total number of 8"+ events to 13. Averaging almost three 8" storms per winter is significant for a town that only sees 36-38" annual average snowfall.

Uncle W, Carl would be able to corroborate Philly for you probably faster than I can.  The Boston snow average is amazing over the last 25 years given the volatility elsewhere.

Hey Tony - I have everything on a manually updated excel sheet so not out of the question there're a few typos, with that being said I have 23.8" for the 1890 decade & 20.7" for the 2000 decade, other (11) decades match my #'s.

I like the rolling 30yr Mean for comparison purpose, these are pure averages & not the official #'s

Yep, impressive stuff over the past several years. As absolute humidity noted, I forgot to add the 12" snowstorm of November 7th 2012 here.

February 2010 had 47" here. And the period Dec 26-Jan 27 had 55"!

I was on the low end of accumulations for the 3/2/09 storm...Eyeballing it at less than 5"...I got 3" from 2/5-6/10...the city got a few flakes...That was the weirdest storm I ever tracked...Your totals are twice as much as mine for most of the storms...

Yeah the whole 09-10 winter favored CNJ southward.

 

I would imagine you were close to me for the boxing day and Jan 27 2011 events in the 2010-11 winter. If I recall the heavy banding definitely impacted Staten Island in the boxing day blizzard.

I have 21.0" for 1999-2000, otherwise the numbers I have agree with BucksCO_PA.

I did a presentation last evening for the East Nantmeal EAC on Weather in Chester County

Snowfall vs PHL was one of the slides. Below are the 13 year totals

2000/01 - 34.1

2001/02 - 9.7

2002/03 - 61.0

2003/04 - 41.5

2004/05 - 37.5

2005/06 - 31.3

2006/07 - 25.3

2007/08 - 13.8

2008/09 - 29.6

2009/10 - 86.6

2010/11 - 45.6

2011/12 - 19.2

2012/13 - 29.1

13 year total snow = 464.3"

13 year average = 35.7"

William,

 

That Upton average really stands out.

It pretty much becomes SNE climate-wise in the winter once you hit central Suffolk county and east, excluding the Twin Forks which are often warmer and don't get as much snow. The NYC area really has been the transition zone in recent years between the Mid-Atlantic climate regime and New England. Last winter highlighted that perfectly with the near misses and glancing blows that hammered Boston and eastern sections of Long Island.

That was also because all the storms were miller Bs which favor that region. You get a classing miller A or coastal hugger further west would do better.

Snow cover is back to average or even below average in spots now. Losing momentum on this from earlier this month     .

Yep. I blame Colorado. They fell apart on us.

Ok...

 

 

[Rainshadow]

In fairness, the Eurasian/Siberian Oct snow coverage worked last winter (-ao formed). But, there was a huge delay in the coupling of the -ao  and the -nao.  Also in the Philly area, the snow cover works better with winter snowfall than it does with temperatures (Mark told me the latter failed statistical tests). The former, not so good last winter.

First 20 days of Oct at phl. ouch.
