Chugwater Sequence 7
By now, the Chugwater tornado clearly was beginning to meet its Chugwaterloo. Though moving toward us in an absolute sense, it had migrated toward the back of the storm while a new (and ultimately non-tornadic) mesocyclone formed in front. The tornado had wrapped so much rear-flank and occlusion-downdraft air that it was getting completely segregated from the original source of warm, moist inflow, and was about to spin down. Meanwhile, unknown to me, large hailstones a few tens of thousands of feet aloft were beginning to drop right downward toward us.
