I hadn't really planned on chasing this day, as the next few days looked to be significant chase days. As such, I did not pay much attention to the situation until very early afternoon. By that time, it was evident that there was a supercell risk across much of the western Plains, from northwestern KS to southwestern TX. Well, I had blown any target out of Oklahoma given my late decision to head out. By mid-afternoon media helicopters were on a tornado-warned supercell that formed along an outflow boundary in west-central / northwestern OK. Off I go.

Given the time, I picked up Kim from work and headed to the northwest. The original supercell dissipated as we approached Geary, though another supercell developed to its northwest. The storm, south of Vici at the time, was displaying nice supercell structure on radar by the time we made it through Watonga. We continued to make a beeline towards vici. Unfortunately, as we neared the storm, we saw nothing but an incredible anemic, dying updraft. After stopping for some pictures of baseball-sized hail in Vici, we had to make a decision -- either head north towards cells that looked to be along the OK/KS border, or head west and hope for initiation that way. After a talk with Gabe, and my desire to avoid "warning chasing", we decided to head southwest into the eastern TX panhandle, where there existed extreme instability and nice shear.

While there was a cyclic tornadic supercell near Hill City, KS, convection in the eastern TX panhandle was weak. We decided to cut our loss and call it a day. In hindsight, I certainly should have paid more attention to the situation and headed to northern / western KS. Unfortunately, I didn't want to overcommit since the following 3-4 days looked like they'd be all chaseable. As it turns out, the next day was garbage. Ugh.

This USED to be a tornado-warned supercell.  Just our luck -- as soon as we got to the updraft, it literally began to dissipate.  It appears as though it was no longer able to ingest surface-based, unstable parcels, likely because of the cooler nature of the outflow air (from morning convection) which it began ingesting. Anemic updraft, anyone? We drove through Vici probably 30-35 minutes after the storm moved through that town.  Most of the town was covered in hail, with numerous 1.5"-2" hailstones. I wonder what size the hail was when it was actually falling... Another large hailstone.  Again, this was about 30-35 minutes after the storm passed through Vici, so it likely lost some mass/size due to melting.
