The weather when arrived at Norris was clear and cold. Over the next few hours, the clouds started to appear. The sun made an appearance at around 09:00 and then the clouds made it disappear, so it stopped warming up. At around noon, it started to get noticeably cooler and a north wind started.
That shifted the steam so that it was now blowing down toward the bridge when it wasn't obscuring our view from the lower platform. By 14:00 the precipatation started, and quickly turned from sleet to snow. We left the platform at 16:20 by which time there was about an inch of slushy snow everywhere. New Crater/Steamboat had been quiet all day, and showed no signs of even trying to give us a decent minor. The drive home was the first in a while where there wasn't a notice of an eruption while we were driving home.
The drive back was loads'o fun. There was a continuous line of cars from the Madison Junction to Fountain Paint Pots. Only part of that was because of a bison heard at Nez Perce. There was a tree overhanging the road at the Firehole Picnic area, and a lone bison starting another blockage just north of Biscuit Basin.
