The Seasonal Snowfall Futility Markers

Recommended Posts

Current as of 1/26/21:

BWI: 2.1" (Would be new 5th place if no more snow falls)

DCA: 0.3" (3rd place worst if no more snow falls)

IAD: 2.6" (currently tied for second worst if no more snow falls)

The futility list:

Could be. I just copied that from the contest thread. In any event, once DCA crossed the 2.3" threshold, this thread drifts away...

These are the updated numbers:

BWI: 6.1"

DCA: 3.5"

IAD: 8.3"

5-year futility is still on the table at BWI, IAD and DCA

IAD's lowest snowfall across 2 consecutive winters is 14.5" from 07-08 and 08-09. A new futility record is still on the table.

19-20: 2.9

20-21: 10.6 (so far)

Adding to this, I've been keeping track of cumulative totals for the three main airports (mainly because I feel like the three in total are pretty representative of the urban corridor for the majority of the subforum), and we're certainly still in the running for overall futility for two consecutive winters in the IAD snowfall era.

Cumulative totals from 19/20 and 20/21 at the three airports: DCA 5.1", BWI 10.8", IAD 13.5" = 29.4" Cumulative total. This would just narrowly beat the consecutive winters of 11/12 and 12/13 where the cumulative total there was just 31.1" total. Honorable mentions would be 2000/01 and 01/02 with a cumulative total of just 37.1", and more recently 2016-17/17-18 where the cumulative total there was 48.8". We're truly entering the period of snowfall booms or horrendous snowfall busts for winters, with not much room in between. On the other side of that coin, the 3 winter stretch of 13/14 through 15/16 was the snowiest three year stretch cumulatively for all 3 airports in the IAD era. In that same era you can group 09/10 with any other winter for all three airports and it will still end up as the snowiest two year stretch for all three airports combined.. so that's fun lol. 

 

Edit as of 2/18/21: DCA = 5.9", BWI = 11.8", IAD = 14.7 = 32.4" Cumulative total (over the past two years). This narrowly edges out 11/12 and 12/13's two year cumulative total of 31.1". The past two years are no longer the least snowiest such stretch for the airports combined in the IAD measurement era. As for @KingJWx mentioning IAD's consecutive snow minimum, they have eeked out 0.2" more than that stretch. Fun times we're in!

The 5-year minimum DC snow total was set during the 1997-98 through 2001-02 snow seasons at 37.7 inches.  The last four snow seasons at DCA have totaled 28.7 inches, and so 8.9 inches or fewer this season would break that record.  The minimum two-season DC snow total was set during the 2011-12 through 2012-13 snow seasons at 5.1 inches.  So, with last season's 0.6 inch total at DCA, 4.4 inches this season would break that record. 

So, with this year's 5.4 inches at DCA, we broke the 5-year minimum DC snow total by 3.6 inches, as the last five snow seasons at DCA have totaled just 34.1 inches, vs 37.7 during 1997-2002. However, we exceeded the 2-year minimum DC snow total by 0.9 inches, as the last two snow seasons at DCA have totaled 6.0 inches, vs 5.1 during 2011-2013.
