It happened last night.
Woke up this morning and winter had snuck in. Winter! And I had not yet even finished the requisite autumnal post.
Snow down to 3,000 meters. Above image shows in the foreground two valleys at 600 meters. The valleys drain the north side of the Jungfrau Massif, part of the Berner Oberland in the Swiss Alps. If you magnify, you can see Jungfrau, Monch and Eiger in the left center background.
