This was the last chase day for Tour 7, and the final chase day of the season for me. \u00a0We had to be in Denver by noonish the next day, so I was hedging towards playing the NE\/WY border area rather than the I-90 corridor through northeastern WY and into SD. \u00a0Like the day prior, when we chased a prolific tornado-producing supercell, wind shear and instability were quite good. \u00a0Moisture was a notch or two poorer, though. \u00a0Dew points today were generally in the 60s, compared to low-mid 70s on June 28. \u00a0I think that the poorer moisture today was the difference-maker, and the supercell that we watched form southwest of Ardmore, SD, became slightly undercut and unable to become a tornado-producer. \u00a0A supercell that tracked into the Black Hills did have a tornado with it on this afternoon.<\/p>\n

Following a visit to Devils Tower and lunch in Newcastle, we continued south on U.S. 85 to the rest stop at Highway 18. \u00a0A handful of decent storm towers was developing to our southwest and west, and moving generally to the northeast. \u00a0I was waiting for one that would be moving into a tongue of good air in the vicinity of Harrison and Crawford, in the northwestern part of the Nebraska Panhandle. \u00a0Given the sparse paved road network, I was reluctant to head directly to a new cell that was a little northeast of Lusk. \u00a0We scooted east to Edgemont, and then southeastward to Ardmore. \u00a0The storm towers, now to our west, were hitting 50k feet on the tops. \u00a0These sputtered a bit, but a new updraft quickly matured to our southwest, closer to Harrison. \u00a0We repositioned from west of Ardmore to a few miles south of Ardmore, barely in Nebraska.<\/p>\n
