November snow in NH can be hit or miss
It may be wise to dust off the shovel or snowblower. After a snowless November in 2015, odds favor some this year.
The last five Novembers in Concord show that snow can be hit or miss in the Granite State during this month.
In 2014, over a foot of snow fell, mostly from the Thanksgiving storm.
But in 2015, the fifth-warmest November on record failed to produce a single flake in Concord.
A few stats based on records in Concord, which reliably go back to 1903:
- One in four Novembers fail to produce more than a trace of snow.
- One in three Novembers produce three or more inches of snow.
- One in four Novembers produce six or more inches of snow.
- One in 14 Novembers produce a foot or more of snow.
Interestingly, of the 113 Novembers on record, 26 had six or more inches of snow and exactly 26 produced only a trace of snow.
Averaging it all out, a "normal" November should bring 2.6 inches of snow to the capital city.
Some spotty data is available back to the 1800s, and the snowiest November turns out to be the year 1873, when 25 inches of snow fell in Concord.
In addition to last year, it did not snow in November in Concord during the years 2001, 2006, 2009, and 1876.
What does this mean for this year?
Statistically, we are favored to have at least some accumulating snow. However, it is interesting to consider that all but one of the years without at least a trace of snow have occurred in the last 15.
