Mount Washington has already had its snowiest June on record

The snowfall data recorded by the observatory goes back to 1932, and the record was set back in 1959, officials said.

“Statistically speaking, our last snowfall of the season typically occurs in early to mid-June most years,” observatory officials wrote on Twitter. “This year was no exception as a quasi-stationary low sat over our region delivering snow nearly every day so far this month.”

Francis Tarasiewicz, a meteorologist and weather observer on Mount Washington, said the record-setting snow “resulted from a stubborn area of low pressure that got trapped beneath an upper-level low.”

“Between the 4th and 10th of this month, low pressure slowly meandered from the Gulf of Maine to the White Mountains,” Tarasiewicz said in an e-mail. “This unique setup meant that the summit received accumulating snow for nearly seven consecutive days!”

The same high pressure that resulted in prime fire conditions in Canada “helped to create a bit of an atmospheric ‘traffic jam’ to the north and east of New England,” Tarasiewicz added. That kept the low pressure trapped over New England before it dissipated on Sunday.

There hasn’t been any additional snowfall, but “there is a small chance for some more later this week as another upper-level low moves in,” Tarasiewicz said.

On Monday the Mount Washington Observatory shared before-and-after photos showing how quickly the snow had melted.

“A return of more summer-like weather has been making short work of melting the snowfall from last week,” officials said. “As an example, here is the 24-hour difference around the summit sign.”
