Snow Squalls, Central Utah

This scene is toward Moab, perhaps past Green River and heading south. The sky was black and stormy, lying close to the ground and moving fast to the east. From time to time a cell in the clouds would lay a swarth of snow a mile or so wide across the ground; elsewhere there was intermittent drizzle. All of sudden there was a rent in the clouds and the clear winter sun hit a mesa that had just been covered by snow. The flow of west wind was causing a small low-pressure ridge over the leading edge of the mesa where a lenticular cloud formed in the moist air. Just as quickly, it was gone.
