While the rest of the state is trending orange, russet and red, Mount Washington turned white Sunday.

The region’s highest peak saw its first measurable snowfall of the season, coming on the heels of a few flakes that fell in August but didn’t accumulate.

Meteorologists recorded 0.3 inches atop the summit on Sunday. Temperatures on Monday didn’t crack 32 degrees, though a little bright sunshine did melt some of the accumulation, according to Alexandra Branton, a weather observer and education specialist at the Mount Washington Observatory.

“As I look out towards the northern portion of the state, I can see fall foliage,” Branton said Monday afternoon. “The leaves look pretty orange, so it is an interesting contrast: the winter conditions on the summit, and the fall conditions down in the valleys.”

Historically, the mountain has typically recorded its first measurable snowfall in September, and an average of 19 inches of snow in October. But in recent years, a changing climate has pushed the start of winter conditions later.

“We are still very behind schedule, so we are at quite the deficit already for winter 2023,” said Branton. Winters have been “starting later and ending earlier” as a result of a warming climate, she added.
