Last week I was out chasing storms and saw a bonanza of shelf clouds south of Phoenix. Later in the afternoon, I went south past Picacho Peak and watched two large cells move closer and closer together until suddenly they merged into a large thunderstorm, with a hail core and structure. It look completely like a supercell and on this time-lapse, you can see the back end of it rotating for a little bit. Early on in both clips you can also see the bluish hail core dump on the right side of the base!
I have a few other clips of the shelf clouds, but really wanted to show this guy. Awesome to see this kind of storm in Arizona…and especially in March! Great start to the year already.
Below is just a still image from this storm. So beautiful!
