April 21 Summary
Chased with Jon Racy, Jeff Peters, and John Saltenberger yesterday. In short, we were between much of the tornadic action.
Summary by Jon R.:
We sat in Clarendon and Claude TX for a good part of the afternoon awaiting initiation west of I-27. We saw two opportunities developing; one NW of LBB and one SW of AMA. We chose the north option, blasting west to the 335 loop and Hollywood Road/FM 2590. Here we observed a rotating cell with attempts at ragged wall cloud features, but no real strong low-level rotation. Inflow was pretty stout as we watched tumble weeds and dust clouds race NW into the storm. But, cells developing and/or sheding from other storms to the south kept raining into the inflow and lowering temperatures into the lwr 60s. The storm flew off to the north and we thought about breaking off and heading south to the Tulia cell.
Instead, we headed north and tried to keep up with the our original supercell, thinking that given the propensity for the Dumas storm to produce, perhaps these cells would get their act together. By the time we got to between Masterson and Four Way, our original cell wrapped up with strong low-level rotation per radar and TVS triggers. We viewed what we thought may have been a white tapered funnel off to the NE of Four Way in the general vcnty of the tornado report, but ontrast was poor. CG lightning frequency picked up for about a 5 min period of time in that general vcnty as well.
That cell quickly became history as it moved at mach speeds NE away from our vantage point. So, we headed east to Lake Merideth on 1913, stopping at a high point just west of the Lake to watch the southern storm flourish into a well-defined bell-shaped supercell complete with a brief blocky wall cloud. By then, it was dark and time to head around the Lake and into the approaching remnant Tulia storm. We met up with it, along with several Norman chasers at an Allsups in Pampa, ate and then departed for Norman, treated to torrential rains and a light show while transecting the squall line near Shamrock.
Thanks to John Hart and Ryan Jewell for their calls tonight. Congrats to all who were on the north and south storms and thank goodness everyone is safe and sound...including the residents of towns affected.
