Not quite red white and blue, but these festive lenticular clouds lit up the summit in shades of pink and blue during sunset last night! Happy 4th of July from the Mount Washington Observatory!

Weather Observer and Education Specialist Bailey Nordin checks in from the summit of Mount Washington to share the current temperature while the Mount Washington Valley hits 91 degrees. For a look at the higher summits forecast, visit mountwashington.org/weather/higher….

Lightning danced around the summit after midnight last night, with this video from our Tower Camera (accessible under "webcams" at mountwashington.org) showing the closest strikes between 1:14 and 1:17 AM.

With temperatures climbing near the 70-degree mark on the summit, even those of us with cold paws are making more ventures into the weather room and even the great outdoors! Pictured here is Nimbus today, on one of his first visits to the weather room this summer.

Our weather team is keeping a close eye on a significant heat event expected across the Mount Washington region, including the surrounding valleys, from Wednesday (7/1) through Friday.

MWOBS Curator Dr. Peter Crane spoke with podcast host Amanda McKeen this week on North Country Community radio, where he shared about mountain weather, local history, folklore, and a life dedicated to stewardship.🎧Listen here: clearviewadvantage.com/podcast/episod…

Looking down at Nelson Crag at sunrise this morning. Heat and humidity is expected in New England in the days ahead. To check how it will affect the summits, check our Higher Summits Forecast at mountwashington.org/weather/higher… #NHwx #NH #mountains #sunrise

@sammy_rufared If we are clear (we're in the fog over 60% of the year), fireworks can be seen, but they are kind of a letdown as we are too far to hear them, and they are a lot smaller than people think, making them look like little dandelions or barely visible at all in the valleys below.

@MWObs 🐾🐾 Hello Nimbus. Will you be seeing fireworks from your mountain top on the 4th ?

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.

@PrincessWB420 The summit staff. We have a sign-in matrix that we initial to indicate whether he was fed in the morning and the evening.

@MWObs Who feeds him?
