The morning started off with two possible chase targets. The first being in sw Kansas. The surface low was progged to be a bit west of there. The forcing was pretty strong and the cap was weaker near the sfc low. The second target area was situated along the dryline through western Oklahoma and nw Texas. Surface Td's was forecasted to be upper 60's across the dryline. However, after morning analysis, it was clear that the models were overdoing moisture return. So, that narrowed down the target area to western ok or sw ok. Cap was forecasted to be stronger the further south down the dl, so the decision was made to go west on I-40 towards Elk City or Shamrock.

We(Jeff Synder, Gabe Garfield, Phil Hurlbut, Jana Lesak, and many others) departed OUN around 11:30am. We made a WIFI stop in Clinton while also grabbing some food. The initial cells had already gone up east of Lubbock, TX. SPC Mesoanalysis showed the cap was weakening across sw OK and a confluence zone located just east of the OK/TX border extending into TX. We made the decision to redefine our target towards sw OK. We went south out of Clinton to Altus. Once in Altus, we obtained some more WIFI and saw the cell develop in extreme eastern TX panhandle. We weren't convinced that that cell was the one we wanted to target. It would move into a low moisture area that would be hard for supercell to maintain low LCL's. After watching this cell for 15 minutes, it began to create subsidence around it, weakening the Cu field in sw OK. It was now apparent that this was the dominate supercell.

We took 283 north from Altus. We proceeded until a couple of miles south of Carter OK(12 miles south of I-40). The storm was high based, due to high dewpoint depression. The storm did show signs of rotation and had some nice curved inflow bands. Then the based dropped rapidly due in part to a wet rfd.





We proceeded about 4 miles east and 1 mile north and stopped again. The supercell now had a nice, fairly organized wall cloud. We could see the rfd beginning to wrap around the back side and a funnel developed and started to lower. The shape of the wall cloud and funnel was the classic, "I'm going to be a big tornado" shape. However, the rfd kind of washed out and didn't wrap all the way around the wall cloud. The funnel dissipated quickly thereafter.



We continued eastward for 5-6 miles and did not like the appearance of the storm. The cell had quickly transformed into a squall line with a big shelf cloud protruding out from the line. There was a kink in the line and GRlevel2 data showed rotation in the little inflow notch. We took a quick peek at that area and it showed no signs of lowlevel rotation. So we decided to throw in the towel and call it a day.
