On Sunday evening, a mixture of discomfort, surprise and delight registered on the faces of people exiting their aircraft at Jackson Hole Airport. As passengers walked across a blustery, cold tarmac to reach the airport terminal, it appeared the page had been abruptly turned on summer. When the wind and sideways rain became volatile, one aircraft diverted to Idaho Falls, ID. (Winter diversions at JAC aren’t all that uncommon but diversions in August are.)

Increasingly cool temps and rain and wind continued into the night, pummeling the valley in Jackson Hole, where many went to sleep giddy, imagining what was transpiring up high. Luckily, our friends at Jackson Hole Mountain Resort were at the mountain this morning to confirm our hopeful suspicions: it snowed. Yes, the tram crew broke out their goggles in August.

Behold the proof above: an image courtesy JHMR of the snowy tram dock stationed at Rendezvous Mountain’s summit (10,450 feet) on Monday morning.

A National Weather Service winter weather advisory for the Teton Mountain Range points to “an unseasonably cold Canadian low-pressure trough,” as the reason for Christmas in August. It will bring periods of wet snow to the northern and western mountains through early Tuesday morning. Four to eight inches of snow are expected at 9,000 feet and above.

Let ‘er buck, JH.
