November snowfall is in a drought, with 15 of the past 17 November months getting snowfall below the 1981-2010 average. The only standouts were 2010 with 17.6 inches and 2005 with 9.9 inches.
Interestingly, this decline in average November snowfall is related to a rise in the average November mean daily temperature. Of course, any given year is likely to reveal a break from the trend. For example, Novembers in 2014 and 2018 were both cold but produced light snowfalls. The relationship shows up much more clearly in 10-year running averages.
The 1990s were particularly cold and snowy during the November months, producing one of the highest average snowfalls (10.7 inches for the decade) and lowest mean daily temperature averages (26.4 degrees). The combined trends of warming Novembers and less November snowfall are both likely fickle, short-term climate trends, and are not likely related to the general warming of Earth's climate.
