If you visit Mount Washington in the summer, Nimbus can occasionally be seen hanging out around the summit. He is not easily spotted, though! His dark grey color is perfect camouflage against the metamorphic schist boulder fields that make up the summit.

While out photographing a pair of #thunderstorms over Maine, being lit by a nearly full moon during astronomical dawn this morning, the ethereal shimmer of #noctilucent clouds quickly stole our attention to our northeast.

This is insane cloud structure for New England standards. This rotating storm came through Georgetown, Topsfield area at around 8:00 PM this evening! Still can't get over this! @ericfisher @PeteNBCBoston @CharlieWGME @TheTKWeatherXp @tuckerweather @weatherchannel @NWSBoston

Loving the trend of northeastern MA being the hot spot for storms this past week.

Pretty robust storm. Torrential downpours and some small hail mixed in.

Happy summer solstice!

Summer night out there with some 70F+ dewpoints. Tomorrow brings the most humid day of the stretch before the drop back for the weekend. #wbz

Quite the contrast in observed conditions for May 2026 in Southern New England (warm/dry) versus Northern New England (cool/wet).

Frosty T. Snowman, sporting his nicest scarf, scratched a June bucket list item off by getting a picture taken by the summit sign this morning.

Photo from work this morning revealing a wintry looking summit cone. Pretty awesome views for the end of May!

[Mount Washington Observatory (MWOBS) @MWObs]

A break in the fog revealed a partial undercast and a wintry-looking summit cone, with 5.9" of snow and sleet recorded over the past 24 hours with the recent storm.

[Ryan Haas @ryanhaaswx]

@TheTKWeatherXp Haha agreed. That’s probably because we don’t usually see this much snow/sleet when the building is open to the public.

[Mount Washington Observatory (MWOBS) @MWObs]

It's snowing and blowing on the summit this morning. Winter weather will continue through the weekend.

@TheTKWeatherXp I am up on the summit now! Lots of mixed precip throughout today with temperatures hovering just above freezing. Looks like we’re back to a wintry mix as of the most recent ob
