The Mogollon Rim Convergence Zone worked its magic the past 3 days with southwest flow leading to some especially favorable shear along the Colorado River Valley.
On my way north to meet the best shear parameters—which I thought would be best near Page and the Arizona Strip, I encountered some heavy convection and a nice roll cloud and gust front north of Cameron on Hwy 89. 
I figured this one would probably stabilize the air mass pretty solidly, so after following it a bit, getting photos, looking for lightning and doing some roadside nowcasting, I started making my way towards Page. A couple hours later I found myself at The Gap to pick up a replacement 9-volt battery for the lightning trigger. Radar showed a couple strong storms lighting up to my south—where I thought things had already been played. So I raced back south and started catching sight of a very healthy looking anvil peeeking over the plateau to my west. Once I cleared the horizon-blocking hills, I got to meet a beautiful Arizona supercell drifting toward me from the west.
This is the first time I've caught Kelvin-Helmholtz waves along the elevated base of a supercell—and it was an hour from home. This view faces northwest as the cell moves over the edge of the Painted Desert.

I followed it through Tuba City and further east where it was trying to hand off to a new base before slowly withering.
