Concord’s official snow-measuring spot at the city airport saw 15.1 inches of snowfall Tuesday, which means the first half of March has seen four times the average amount of snow for the month – not counting the flakes that are still falling Wednesday morning.

According to the National Weather Service, Tuesday’s snowfall fell a whisker short of Concord’s record for March 13, which was 15.5 inches in 1993. But we’re still snowy: Since March 1, the airport has seen 26.1 inches of snow, more than four times as much as the 30-year average of 5.5 inches.

It has been relatively fluffy and light snow, however. Meteorologists melt snow to see how much water it contains: The normal amount so far this month is 1.07 inches of water, while the 2018 snowfall has melted to 2.36 inches – in other words, while we’ve had four times as much snow depth as normal, the snow has only held a little over twice as much water as normal.

Snow measurements from Tuesday’s storm varied widely. Depths measured by volunteers for the national citizen-science program known as CoCoRaHS were as high as 27 inches in Deerfield and 20 inches in Dunbarton to 8 inches around Lake Winnipesaukee.

As reported Tuesday in the Monitor, the snow set a record in another way: This was the first time in the 75 years that records exist in which snowstorms have struck on two town meeting election days in a row. And both those snowstorms dumped almost twice as much snow as the next-snowiest storm that election day has ever seen.

By the way, even though this winter might seem long and cold, we’ve actually been warmer than normal. Since March 1, we’ve had 11 percent fewer heating degree days – a measure of temperature over time – than normal.
