New England "March" Snowfall Data (1882-2017):

[ncforecaster89]

Thought I'd share the research I've been conducting into the official climatological data for major reporting sites throughout SNE.  This thread is being created with the intention of sharing additional information, as I have time to compile the corresponding data, for all other official observational locations, as well.  For this particular endeavor, the period consisting of the past 60 years was selected; whereby the two most recent 30 year climatological periods can be used for comparative purposes.                

The first installment of data will focus on snowfall observations collected at KBOS (Boston, MA) during the month of March.

UPDATE (2/16/2018): Have since decided to extend this research back to 1891...coinciding with the beginning of official snowfall records for Boston.        

UPDATE (3/20/2018): Have begun to provide listings of the top 10 snow-producing storms/events for many different locations (at their respective official observational sites) throughout all of the New England states; not just SNE, exclusively.      

MARCH CLIMATOLOGICAL SNOWFALL DATA FOR BOSTON, MA (1891-2017):

 

1) How many "warning" criteria snowfall events (>/= 6") have occurred?

A) Entire period of record (1891-2017): 

There were 53 distinct events that occurred during the past 127 seasons (See figure-1 for a list of each specific event).       

B  Most recent 30 year period (1988-2017): 14 separate events transpired during 11 individual years.

C) Previous 30 year period (1958-1987): 13 separate events during 10 individual years.  

2) How much total snowfall accumulated during the aforementioned periods, and what were the average seasonal amounts?

A) Entire period of record (1891-2017): 951.6” total. 7.49” avg.

B  Most recent 30 year period (1988-2017): 246.0" total.  8.2" seasonal avg.

C) Previous 30 year period (1958-1987): 255.7" total. 8.5" seasonal avg.

3) What is the mean statistical return period for a 6", 9", and 12" snowfall event, respectively?

A) Entire period of record (1891-2017):

6" = once every 2.39 years

9" = once every 6.1 years

12" = once every 17.1 years

B  Most recent period (1988-2017):

6" = once every 2.1 years

9" = once every 5 years

12" = once every 10 years

C) Previous period (1958-1987):

6" = once every 2.3 years

9" = once every 5 years

12" = once every 30 years.                    

4) What were the top 3 events for each designated climatological era?

A) Entire period of record (1891-2017):

3/03-05/1960 = 19.8" (11.4" on the 4th)

3/03-05/1891 = 15.5" (12.0" on the 4th)

3/19-20/1956 = 13.3" (13.2” on the 19th)

B  1988-2017:

3/07-08/2013 = 13.1" (10.5" on the 8th) 

3/13-14/1993 = 12.8" (12.3" on the 13th)

3/05-08/1996 = 12.4" (6.5" on the 7th)

3/15-16/1967 = 10.0" (7.1" on the 16th)

5) What were the greatest and least snow-producing seasons (See figure-2 for list of individual seasonal totals) for "March?"

A) Most prolific:

1891-2017 = 38.9” (1993)

1988-2017 = 38.9" (1993)

1958-1987 = 22.9" (1967)    

B Least abundant:

1891-2017 = T (8 different seasons)

1988-2017 = T (2006)

1958-1987 = T (1979) 

6) What are the current "daily" snowfall records for the month of March?:

See Figure-3, contained in a separate post in this thread, for a list of the "new" snowfall records for each day of the month.

7) How many Blizzard events materialized and verified in the city of Boston (1945-2017)?:

See Figure-4 for a list of all blizzard events. It's important to note that I was unable to locate wind data for any of the winter storms prior to 1945.  As a result, I couldn't ascertain if they met official blizzard criteria.         

A) Entire period of record (1945-2017):

Six discrete storm systems achieved blizzard status throughout this Era. An additional eleven were near-blizzards.    

B  Most recent 30 year period (1988-2017):

There have been only two verifiable blizzards that took place in the last 30 years.  However, seven other winter storms brought near-blizzard conditions to the city.       

C) Previous 30 year period (1958-1987):

This epoch delivered four major blizzard events, with four others distinguishing themselves by impacting Boston with near-blizzard effects.

Great research , let it happen .......After April 1, don't want it.......would be nice to have a few more "plow" events.......

Great stuff, you should have gone back to 56

Thanks!  Even if SNE doesn't get another truly significant event to justify a chase, for myself...I'm still rooting for you guys to get another warning-level event or two,  before this season comes to a close.

Thanks Ginx!  Actually, just finished compiling the data back to 1891.  Will update this thread as soon as I can post it.  Possibly as early as this evening or prior to tomorrow morning.       

Noticed 1956 had three separate events exceeding 6"...the largest one being 13.3" on 3/19-20/56.  

Total for the month came to 31.2". It snowed on 17 different days, as well.  Snow-depth was recorded at 18" following that largest event.  

A repeat of '56 would be awesome!

Still need to add the other twenty-seven 6” events to figure-1...as well as the contents corresponding to figure-4.  I’ll do my best to get it done over the weekend.  Furthermore, I intend to provide some of the most relevant information and stats regarding the seventeen blizzard and near-blizzard events referenced above.  

In the meantime, I hope the impending winter storm delivers a fairly widespread warning-level event to as many of this sub-forum, as possible, and each of you have a great weekend, regardless!

As time permits, I’ll add the aforementioned “Figure” listings corresponding to the post shown directly above.  In the meantime, thought I’d go ahead and share what’s already been obtained and tabulated.

As noted in the preceding post, there is quite a bit of missing and incomplete data associated with the climatological record for Hartford.  This includes no snowfall data for the four-year period of 1997-2000.

FIGURE-4: Blizzard’s in Hartford (1955-2017):

1) 3/16-17/1956 (Near-blizzard):

a) Hours of blizzard conditions = 2.5 (330-430 pm, 930-11 pm/16th)

b  Highest observed wind gusts = 52 mph sustained/61 mph gusts

c) Total snowfall = 6.1”  

d) Lowest barometric pressure = 29.30 in./992 mb 

e) Additional noteworthy obs = 19 hour snow duration.  Light snow began to fall around sunrise on the 16th, fluctuating between light and moderate intensity throughout the day.  Shortly after sunset, sleet mixed with the snow, prior to a switch back to all snow...accompanied by a short period of blizzard conditions between 930-11pm.  Snow departed the area by 330 am on the 17th.  

2) 3/19-20/1956 (BLIZZARD???):

a) Hours of blizzard conditions = 5.0 (730-1030 am,1130-130 pm/19th)

b  Highest observed wind gusts = 29 mph sustained/ 40 mph gusts                         

c) Total snowfall = 14.0”

d) Lowest barometric pressure = 29.74 in./1007 mb

e) Additional noteworthy obs = 20 hour snow duration.  The overwhelming majority of the snowfall took place between 230 am and 1030 pm on the 19th.  The records only consist of the observed sustained wind speeds.  Consequently, one is left to surmise whether or not the 20-29 mph sustained winds were accompanied by frequent gusts of 35 mph or greater during the interval associated with 1/4 sm visibilities.        

3) 3/14-15/1958 (Near-blizzard):

a) Hours of blizzard conditions = 2 (1230-230 pm/14th)

b  Highest observed wind gusts = 28 mph sustained                        

c) Total snowfall = 6.3”

d) Lowest barometric pressure = 29.41 in./996 mb

e) Additional noteworthy obs = 21.5 hour snow duration over the course of two days.  Snow began early on the 14th.  Then, turned to rain during evening hours, before flipping back to light snow around midnight on the 15th..ultimately culminating with light snow showers shortly after sunrise.  Visibility got down to 1/16 sm at peak of blizzard conditions!

4) 3/03-05/1960 (BLIZZARD):

a) Hours of blizzard conditions = 4 (430-830 pm/3rd)

b  Highest observed wind gusts = 24 mph sustained                        

c) Total snowfall = 13.0”

d) Lowest barometric pressure = 29.25 in./990 mb

e) Additional noteworthy obs = 40.5 hour snow duration over the course of three days; most of which fell on the 3rd.  As was the case with the 3/19-20/1956 major winter storm, one is left to deduce whether or not the recorded sustained winds of 20-22 mph were attended by wind gusts of blizzard-criteria.  The NWS made the following assertion in the climate report for March 1960; “March came in like a lion with the breadth of cold temperatures and the force of a blizzard early in the month...”  These presumed blizzard conditions were accompanied by +SN, BLSN, and 3/16 sm visibility...giving further credence to the prospect that this particular storm system, did in fact, achieve blizzard status.     

Note: Still in process of investigating and researching various records to determine which winter storms impacted Hartford with either blizzard or near-blizzard conditions.  Will continue to update this post as the process continues.

FIGURE-4: Blizzard’s in Hartford (1955-2017):

1) 3/16-17/1956 (Near-blizzard):

a) Hours of blizzard conditions = ???

b  Highest observed wind gusts = 50 mph sustained/61 mph gusts

c) Total snowfall = 6.1”  

d) Lowest barometric pressure = 29.30 in./992 mb 

e) Additional noteworthy obs = 19 hour snow duration.  Records only available at six hour increments, thereby making it impossible to determine whether any blizzard conditions occurred.  Given intensity of winds observed here, period of blizzard conditions recorded at KBOS, and record of blowing snow (BS), it’s likely this event was a “near-blizzard” at KBDL.           

2) 3/19-20/1956 (Near-Blizzard):

a) Hours of blizzard conditions = ???

b  Highest observed wind gusts = 40 mph                         

c) Total snowfall = 14.0”

d) Lowest barometric pressure = 29.74 in./1007 mb

e) Additional noteworthy obs = 19 hour snow duration.  As was the case with the storm system that preceded this one, observations suggest a period of near-blizzard conditions manifest itself during this event, as well.  KBDL records list both BS and FZFG lending further credence to the prospect.      

3) 3/24/1956 (Near-blizzard):

a) Hours of blizzard conditions = ???

b  Highest observed wind gusts = 35 mph

c) Total snowfall = 6.8”

d) Lowest barometric pressure = 29.58 in./1001 mb

e) Additional noteworthy obs = Snow duration of 14 hours.  Using the same deduction, the record of BS and FZFG here, combined with almost 6 hours of actual blizzard conditions at KBOS...suggests it’s possible near-blizzard conditions occurred in Hartford.      

Note: Still in process of investigating and researching various records to determine which winter storms impacted Hartford with either blizzard or near-blizzard conditions.  Will continue to update this post as the process continues.

No doubt!  Looking forward to history repeating itself, at some point...hopefully during our lifetimes.  Of course, I’d choose a repeat of March 11-14, 1888 if given such a choice.  

Since I made the post you copied above, I was able to locate additional data helping to clarify which storms might’ve delivered blizzard or near-blizzard conditions.  The aforementioned post has since be revised and updated, accordingly.  Only through 3/1960 thus far.

Obviously, the jury is still out on how significant the 3/2-4/2018 system may be, but I wouldn’t be too surprised (50% probability at this range for me) to see it materialize as a MECS...albeit, I’m not as confident on this system as I’d like to be, quite honestly.  If it doesn’t phase properly and/or in time to make a major impact on SNE, I will be somewhat surprised if we make it through the next 2-3 weeks without just such a system.  I’d place the probability at 60%, myself, that there will be a MECS...given the various teleconnections and a more favorable pattern as we enter this upcoming period.

I posted the top 10 list for Worcester a couple of days before this most recent event in anticipation of it joining the list.  With the 21.8" storm total (in one day no less, & new single day record for March), it comes in at #4 for the city!  Makes two top 10 March events in less than a week!!

MARCH CLIMATOLOGICAL SNOWFALL DATA FOR HARTFORD, CT (1905-2017):

 

2) How much total snowfall accumulated during the aforementioned periods, and what were the average seasonal amounts?

A) Entire period of record (1905-2017): 855.0” total. 7.8” avg.

B  Most recent 30 year period (1988-2017): 219.5" total.  8.4" seasonal avg.

C) Previous 30 year period (1958-1987): 266.6" total. 8.9" seasonal avg.

In my profession, and in most others I imagine, this data is what we would call "garbage".

I like the thread though. Just not CT's recordkeeping.

Totally agree with you on the poor record-keeping, there.  Not sure how there is no observational snow data for the four year period of 1997-2000 or how they don't list any snowfall for their likely greatest snow event.  

Thanks for the kind words,  as well, JC!

3/19-20/1944 just missed - looks like 10.7".  I've read that Boston got close to a foot of tainted paste from 3/1888.  I've only found 2 NNE sites with records for that event - Gardiner, Maine had 8" of 32+ paste, and ASH had 30", with temps falling to low/mid 20s, their greatest snowfall on record.

Hi Tamarack!  You're right about the 1944 storm falling just outside the top 10 storms of record; categorized by total snowfall.  

I, too, am fascinated by historical accounts of the great 1888 blizzard.  Especially,  given that it's simply a matter of time before a repeat of the meteorological dynamics conspire to produce the same event.   Although, it's virtually impossible to replicate the societal impacts in this day and age...which will guarantee the March 1888 blizzard will, arguably, remain in a class by itself...relative to overall impact.  The blizzard's of 1993 and 1978 aren't too far behind, however.  Then again, we have no record to compare whether the 1888 event was, itself, a meteorological descendent of a previous centennial-type storm.

1888's combination of snow, wind, and cold - albeit for a smaller area than storms like 1993 - will be tough to match.  Snow, wind, and anomalous cold, even tougher.  NYC's temp on 3/13/88 was about 30° BN; how many major snowstorms can equal that.  Nearest of my experience was April 1982, which was the lesser event in all three of the above parameters but was still a cold midwinter blizzard in April.
