Chase Accounts

Robert Satkus -- Bobby Payne and I chased the central Ok storms on 4-26, knowing the chances for tornadoes were slim at best. We expected lots of hail and that is what we got. The first storms went up near Anadarko. We headed west then south from Norman towards Blanchard. We did briefly see a large lowering to our southwest, but no rotation. We hit the first core near Dibble, with pea to dime size hail covering the ground, along with torrential rain and minor flooding. Several new cells redeveloped along the outlow boundary in the same general area. We had 3 more encounters with hail near Dibble and north of Lindsay, but it was all dime size or less at times covering the ground. One storm seemed stronger than the rest and tracked east to near Purcell and Wayne towards Byars. We followed it along staying south of the core, but it remained rather featureless. We let it pass to our east and couls see some nice crispy towers, but thought it would be a waste of time to continue. We could see anvils to our distant northwest, but figured these would soon weaken if they weren't already as susnset was approaching. We headed back to Norman but watched with interest as these western storms grew larger. As we arrived home we could see a backsheared anvil and an overshoot. A report of golf ball hail near Watonga had us forgetting about where to get dinner and back out the door! A tornado warning was soon issued and from Hwy 9 west of Norman we could see a large wall cloud at least 30 miles away! We continued to Newcastle then west towards Minco, but the lowering didn't seem as impressive. As dark set in we headed south from Minco towards Pocasset and the storm ( through lightning flashes ) appeared to be more outflow dominant although the updraft had a laminar appearence to it. We went through Chickasha and could now see a shelf cloud was spreading out ahead of it. About 10 miles south of town we got a barrage of nickel hail as the storm began to collapse. Had a nice view of what was left of the storm in the moonlight and occasional last gasp lightning as we headed home.
