The third day of my Plains Chase Tour this spring was a marginal one, we woke up in Garden City on May 31st and by mid-afternoon we were in Lubbock chasing storms to our south. We got on one that was okay, but then a storm near Lamesa formed and we noticed an outflow boundary headed for it from the east. We hoped it would give it some extra juice and by the time we got down there, it certainly turned into a full-fledged gorgeous supercell for about an hour.
This was southeast of Lamesa and wow did it look stunning. All the dust churning underneath and the teethy low clouds on the left side. One of my favorite storms from this spring and all on a marginal day!
