June 21 was a good set up for late June in the Texas Panhandle. Strong deep layer shear, a sharp dryline and high CAPE would provide a set up for supercells. Mid afternoon an LP supercell developed north of Amarillo and stayed on the triple point for a couple hours. Eventually the storm moved south along the dryline and became an incredible hail producer. It produced hail to cantaloupe size in Amarillo that caused $100m damage. This storm also produced several weak tornadoes.

LP storm forms. A nice horseshoe vortice developed and helps attest to the shear available that day.	Storm intensifies as it slowly moves south/southwest. It was severe warned at this time. Rock hard updraft and inflow band are evident.
Very large laminar funnel forms and kicks up dirt on the ground. This came close to being a significant tornado!	A second tornado forms. Can you find the light colored pencil shaped funnel above the debris swirl on the ground? This tornado only lasted 3 minutes.
Strongly rotating meso and wall cloud. I was showing nearly 150 kt gate to gate shear here!!! If surface and 850 winds were a bit stronger there would have been a large destructive tornado.	An inflow jet developed with dirt pulled into the updraft at 40 kts!!! Very intense lightning was occurring under the forward flank core.
Brief spin up occurs with strong RFD near I27 south of Amarillo. Motion was incredible!
