On the afternoon of Sunday, August 16, 2020, I bolted north to David City to meet up with a southeastward moving cluster of supercells, which were gradually congealing into a forward-propagating MCS. For the second time in three days, I was treated to beautiful landscapes and storms (see southwest moving tornadic supercell from August 14), as I got to watch somewhat discrete updrafts briefly acquire rotation and then merge, with the Platte River valley in the foreground. Once storms became a linear cluster, they accelerated south, and I had trouble getting back ahead of the ribbon-like shelf cloud. I finally got well ahead of the southwest corner of the gust front near the Schoenstatt Shrine north of Crete, NE. The Catholic chapel in the background peeking above the woods, at the end of a winding gravel road, combined beautifully with the wavy lobe and cleft pattern in the shelf cloud along the gust front.
This chase continued to the northwest as more supercells, and eventually a second storm cluster, moved south-southeast in the northwest flow regime. The sunset with mammatus trailing the second storm west-northwest of Lincoln was brilliantly colored, and will likely be featured in another post.
