Mesoscale Discussions (MCDs):

First chase with all 3 radars saw mostly multicell convection that developed from W of Tulsa southwestward towards Purcell. We scanned from a parking lot in Seminole for a while before we noticed a lowering that looked suspiciously like a wall cloud to our NW. We headed N to I40, then eastward as the lowering persisted. Subsequent radar data from KTLX showed that a supercell was maturing within the larger convective line. A wet RFD soon developed just N of I40 W of Okemah, and we found a deployment location a couple miles N of Okemah as the mesocyclone occluded. The data are quite interesting given the proximity of the occlusion to our location (within a mile or two). We followed the storm eastward to Henryetta before sunset and before turning around to head back to OKC.
