What Are Your AMWX/ Eastern, etc. Snow Stats?

[Cold Miser]

This may be the nerdiest thing I've done in a while, but I thought it would be cool to see what everyone's historical snow related averages, and other stats are that they have saved since they've been a part of this community.  I joined at the tail end of the Eastern Days, and have been here for about 10+ years. 

Examples of stats to post:
Largest one time snowfall
Deepest snow depth in a season
Longest number of days with measurable snow on the ground
Largest seasonal snowfall (entire season)
Smallest seasonal snowfall (entire season)
Longest period at or below freezing
All time snowfall Average (include the number of years that you have been a part of this community)
Have you had a winter weather season (fall-to-winter-to-spring) where you had measurable snow during each of the big 3 holidays ...Thanksgiving, Christmas, Easter? If so what year(s)? 

Plus, any other statistics that come to mind.

My Stats are from 2009/2010 - 2018/2019
10 season Average: 66.35"
Smallest seasonal snowfall: 26.25" (2011/2012)
Largest seasonal snowfall: 100" (2014/2015)
Largest one time snowfall: 29" (2/8 & 2/9, 2013)

I thought so too, but it didn't show up in my list of complex stats. lol.  
I will have to look back again.

That holiday one is probably the only snow-related one in your list that I don’t typically track – it’s a bit tougher to track easily because the dates of Thanksgiving and Easter vary each year.  That will be fun to look into though – I’m interested to see if it’s happened at our site.

As for other stats, Tamarack and I have a million of them (I don’t track temperatures, but I’ve added a number of snow stats through the years as I learn about them from Tamarack).  We’ve been discussing them in the NNE thread over the past few weeks as we often do at the end of the season.

Tamarack will likely enjoy this thread as well though, he loves weather stats.

Here are some of the snow-related stats that I track:

• October snowfall

• November snowfall

• December snowfall

• January snowfall

• February snowfall

• March snowfall

• April snowfall

• May snowfall

• Total season snowfall

• Number of storms

• Number of ≥6” storms

• Number of ≥10” storms

• Number of ≥12” storms

• Number of ≥15” storms

• Number of ≥18” storms

• Number of ≥20” storms

• Number of ≥24” storms

• Average inches of snowfall per storm

• Largest snowstorm

• Starting date of largest snowstorm

• Max snow depth

• Date of max snow depth

• Snow depth days

• Earliest frozen precipitation

• Earliest accumulating snowfall

• Start of continuous snowpack

• Latest accumulating snowfall

• Latest frozen precipitation

• Last day of continuous snow at stake

• Last day of continuous snow in yard

• Days with continuous snow at stake

• Days in yard continuous snowpack season

• Days in yard snowfall season

• Total liquid during accumulating snowfall season

• Snow+Sleet L.E. during accumulating snowfall season

• Total Snow/Total Water (Snow/Water Ratio)

• Average water content of all precipitation

• Total Snow/Snow+Sleet L.E. (Snow/Water Ratio)

• Average water content of snow/sleet

• Days with trace snowfall or greater

• Snowfall by date

• Snowpack depth by date

I've lived in the mid-Atlantic for nearly all my life (just north of the Baltimore beltway and west of I-83), and I'll probably be in New England depending on where my job places me, but I'll share my mid-Atlantic stats anyways. All of this is from 2000 onwards.

Largest one time snowfall: 27" (January 2016) or possibly 28" from PDII but that's based on the nearest reported total I'm aware of
Deepest snow depth in a season: ~36" (Feb 2010)
Largest seasonal snowfall (entire season): 85" (2009-10)
Smallest seasonal snowfall (entire season): 5" (2001-02)
All time snowfall Average (99-00 to 18-19): 27.9" (looks a tad high for the area, probably because of the good years and small sample size)

That 09/10 season was awesome for you.  That was one of the seasons where you "stole our snow"

Have you had a winter weather season (fall-to-winter-to-spring) where you had measurable snow during each of the big 3 holidays ...Thanksgiving, Christmas, Easter? If so what year(s)? 

So I looked into this one when I had a moment, first checking on when there was at least snow on the ground for the three holidays in the same season.

Having snow on the ground for Thanksgiving is fairly common, with an occurrence of 61.5% in my data set.  Snow on the ground for Christmas is certainly the norm (>90%), with only the very aberrant 2015-2016 season not having snow until the 28^th of December.  Snow on the ground at Easter is running at 46.1%, so a bit lower than Thanksgiving.  Checking for where things line up gives five seasons: 2007-2008, 2013-2014, 2014-2015, 2017-2018, and 2018-2019 with snow on the ground for all three holidays in my 13-year data set.  That’s an occurrence of 38.5%.

Having actual accumulating snowfall on those holidays is definitely going to be a rare bird, at least based on what I’ve seen in my data thus far.  The toughest one appears to be Easter.  There’s only one Easter (2014-2015) with accumulating snowfall on the actual holiday in my data set, so that’s an occurrence of 7.7%.  It’s much easier to get snowfall on Thanksgiving.  That’s a rather snowy time of year around here, with close to a 50/50 chance (46.1%) of having accumulating snowfall on the day.  All things being equal, Christmas should probably be the strongest contender for having snowfall on the holiday, but there have also been a number of holiday periods in recent years that have been rather blasé with respect to winter weather.  In any event, Christmas still does appear to come out on top with a snowfall occurrence of 53.8%.  Assuming no correlation between the occurrences (I guess there could be a bit between Thanksgiving and Christmas, but Easter is so far from those two that it’s likely none), the odds of getting snowfall on all three holidays in a season is around 2% for our site.  I’m not sure what the chances are at other sites, but it’s pretty low here.

So did an occurrence of accumulating snowfall on Thanksgiving, Christmas, and Easter in a single season pop up in my 13-year data set?  No.  The closest contender was, not surprisingly, 2014-2015 – the only season where we had snowfall on Easter itself.  That season even had snowfall on Thanksgiving, but ironically, it was Christmas that season that didn’t have any snowfall.

My Stats are from 2009/2010 - 2018/2019
10 season Average: 66.35"
Smallest seasonal snowfall: 26.25" (2011/2012)
Largest seasonal snowfall: 100" (2014/2015)
Largest one time snowfall: 29" (2/8 & 2/9, 2013)

Some of that data is in my sig.  I'll add that my least snowy 12-month period was Feb. 2006 thru Jan 2007 when just 26.9" fell.  Ironically, the max 12-months began in March 2007 - from then thru Feb 2008 I measured 178.0".
I also haven't tracked Holiday snows, though I'm confident I've never seen accumulating snow on all 3 in the same season.  Biggest T-Day snowfall is probably the 3.7" in 2005, also noteworthy for the 2 cold-air tornados, EF-1 and EF-0 in Maine's midcoast during the storm.  (I had had no idea such things were even possible.)  Biggest for 12/25 was the 8.0" in 2017, also 8.0" in Fort Kent (storm of 25-27 totaled 16.5") though we had about 15" (plus first thundersnow of my experience) on 12/24/66 in NNJ with the finishing flakes after midnight - does that count?   Biggest Easter snow was 3/29/70, another NNJ event, when we had 11" of mid-20s pow thru the middle of the day. 

This past winter's 162 consecutive days with 1"+ is 1st place by 20 days.  Also had 1 day in Oct for 163 total, tops by 13.

Without parsing 21 years' data, I know that the 33 consecutive sub-freezing days Jan 20-Feb 21, 2015 take the prize.  The temp popped up to 35 on 2/22, probably above 32 for no more than a couple hours, and was followed by 9 more sub-freezing highs thru March 3. 
Except for 2/22, the highest temp 1/20 thru 3/3 was 29.  For those 43 days (includes 2/22), average high was 19.3, low -7.0, avg 6.1, 10.5° BN.  29 of the 43 had subzero minima and another 5 hit zero or +1.

Biggest snowfall by month:  Also, in italics, biggest at Gardiner(G, 85-86 thru 97-98) and Ft. Kent(FK, 1/1/76 thru 84-85)
OCT:  6.3", 29-30/2000  (29th max was 31, only sub-freezing in OCT)   G: 1.8", 1988; FK: 4.0", 1981
NOV:  26-27, 2014    G: 8.5", 1989 (thunderblizzard); FK: 8.0", 1983
DEC:  24.0"  6-7/2003   G: 17.5", 1995; FK: 16.5", 1978 (8.0" on 25th)
JAN:  20.0"  27-28/2015  G:  16.0", 1987  FK: 13.0", 1977 and 1978
FEB:  24.5"  22-23/2009 (max depth 49")   G: 15.0", 1995; FK:  18.5", 1984
MAR:  19.9"  7-9, 2017 (Hon men: 19.0" 30-31/2001)  G: 10.7", 1993 (the superstorm, 6:1 rimefest); FK: 26.5", 1984  (65" pack, about 16" SWE)
APR:  18.5", 4-5/2007  G: 11.0", 1996  FK:  17.0", 1982 (With winds gusting 50+.  CAR recorded 26.3")
MAY:  0.3", 12-13/2002  (3.0" Farmington, latest 1"+ on record)   G: Can't recall any.  FK:  2.2", 1984  (Also 1.5" in 45 minutes on 5/7/76 as I tilled the garden)
Fort Kent also had traces in June 1980, August 1983, and September 1977.  The June/Sept events brought 1-2" above 1000' elev.)

My average winter at Fort Kent had 134.3"; in Gardiner 79.2".  Both numbers were significantly higher than those town's co-ops, which did one-a-day obs.  FK obs are particularly ludicrous, with winter's average more than 20" less than at CAR despite a FK/CAR eyeball test indicates the opposite.

I was in college at Towson for PD2 and had 29”. Still the single largest snow storm I have experienced. When you throw in the 3” from the day before it was really like a 32” storm.

My time lurking on the forums actually go back to the 2000-2001 winter, but I didn't start posting until WWBB in 2004-2005. The following since 2000-2001....not my entire life. Other metrics may be exceeded if I expanded it to my entire life.

 

Anyways:

Largest seasonal snowfall: 119.7 (2014-2015)

Lowest seasonal snowfall: 43.8 (2011-2012)

Highest storm total: 34.5" (Jan 26-27, 2015)

Deepest snow depth: 49" (Mar 2001)

Longest period with snow OTG: 113 days (Dec 19th, 2000 - Apr 10th, 2001)

Longest period of time below freezing: 22 days (Jan 10, 2003 - Feb 2, 2003) [minor note: 2015 just barely missed 32 days having hit 34F for a few hours overnight on Feb 4-5 between Jan 23 and Feb 22]

Snowfall seasonal average since lurking in 2000-2001: 79.1

 

[OceanStWx]

I think I joined up in the winter of 2006-2007 while I was in grad school at UML.

Largest seasonal snowfall: 98.0 (2012-2013 Portland)

Lowest seasonal snowfall: 32.4 (2006-2007 Lowell)

Highest storm total: 31.9" (Feb 9-10, 2013 Portland)

Deepest snow depth: 25" (Feb 2015 Portland)

Longest period with snow OTG:  93 days (Jan 4th, 2015 - Apr 4th, 2015 Portland)

Longest period of time below freezing: 15 days (Dec 25th, 2017 - Jan 8th, 2018 Portland)

Snowfall seasonal average 2006-2007: 66.9"

If you had asked me prior to running the numbers I would've been sure that my lowest snowfall season would have been at DVN, but I actually had two winters there over 50" (which is solidly above normal for them). 

[dendrite]

I lost a lot of my data on a hard drive failure, but I've jumped around locations since getting on the forums on AOL and TWC back in the day. From what I can recall...

 

Largest seasonal snowfall: 142.7" (2007-2008)

Lowest seasonal snowfall: 33.4" (2015-2016)

Highest storm total: 25" (3/5/2001)

Deepest snow depth: 43" (Mar 2008)

Longest period with snow OTG: Not sure, but probably 07-08.

Coldest temp: -28F (1994)

Seeing this sent me back to my records, and I found that Jan-Feb 2015 wasn't the slam dunk that I thought, though its 33 days is still longest.  However, Jan 2-31, 2003 misses by just 3 days.

Also, dendrite's post had coldest temps, which I'd mostly ignored (until now):
Coldest morning:  -36 on Jan 16, 2009  (Have reached the -30s 5x:  -30 in Jan 2005, -36/-34 in Jan 2009, -31 in both Jan 2014 and Dec 2017.)
Coldest mean:  -16 (-1/-31) on Dec 29, 2017
Coldest max:  -8 on Jan 15, 2004  (Afternoon of the 14th topped out at -11 but "only" -7 at my obs time the previous evening.)

I had assumed 2015 would be the longest period below freezing too....but then was surprised when my numbers said January 2003 had a longer streak.

 

Of course, as noted in the post, 2015 barely missed beating 2003 by 10 days because of a mere few hours spiking to 34F on Feb 4-5....ironically, during a snow event. Aside form those two years, 17 days seemed to be a popular number. Achieved in Jan 2004, Jan 2009, and Dec 2017-Jan 2018. I was amazed at how many below freezing streaks were broken by unremarkable temps...like a random high of 35F or something and then it went below freezing for another week. I almost expected more cutters or torches to break the streak but they were rarer to occur immediately following a deep cold snap.

 

I didn't list the coldest temp, but that occurred on February 14, 2016....ironically during a torch winter. That was the coldest temp recorded in ORH since 1957 at -16F.

Yeah it really was incredible. What made it even more spectacular was the way that we arrived at that total. The storm in December 2009 had about 18-24", but even then I had a feeling that it wouldn't be our only HECS of the season. But never did I imagine that we'd get two more historic storms back to back, which we did in early February. That 12 day period from 1/30 to 2/10 delivered around 55" total where I lived. It would be impressive just about anywhere outside of a mountain, but for the mid-Atlantic it was completely unreal.

I wasn't far from Towson. I lived in Lutherville at the time and that 28" total that I saw was in fact Towson, so 28-29" sounds about right. And I think the total included the 3" from round 1.

The winter BWI recorded more snow than CAR, possibly the most anomalous snow stat I've seen in the Northeast, with the 2011 Octobomb its nearest competitor.
BWI's top percentages of CAR snowfall:
2009-10   109.6%
1995-96    56.7%
1961-62    51.5%
1963-64    50.9%
2002-03    49.6%

Edit:  Forgot to add that, on average, BWI snow is 18% of that at CAR.
