0422jd081Michael Bath and I targeted NW Oklahoma - in fact we dropped down from Kansas. 0422jd102It annoyed me because we had no coverage and no data at all for the entire chase! Back to the old days! The first cells struggled whilst we looked at the cells on the Kansas border. A lot of pressure to head up north but we remained on our target. 0422jd096The issue was that the anvils were raining on the updraft air for the first and then second and finally the third storm which favoured a left moving environment. In the distance to the WSW was the struggling cells with structure we liked. So took the gamble and headed towards it.Just NE of Arnett. we had to turn south to escape the hail. I did not realise whilst driving at the time, but our photos showed the split! Nevertheless, our target was always going to be the southern structure. We stopped E of Arnett and filmed the storm with possible wall cloud and beaver tail and it was this time the storm first weakened into a linear structure. We headed east and photographed the storm periodically. The southern section improved and we spent the next 4 hours side stepping the anvil rain south east all the way to Clinton and Weatherford. It exhibited the best structure near Highway 34 north of the intersection with 33 (Leedey). It was here I photographed the vault and thankfully we could remain east to east southeast of the storm. It was one incredible chase and the structure awesome!
