Time Odom. Town/Heading Remarks

10:42 703 LIBERAL, KS: Leaving town. Heading South. Looks like a TX panhandle day again. Rt. 83 S.

11:31 754 PERRYTON, TX- Low overcast, strong east winds. Some patchy fog.

Upper low has remained nearly stationary over Las Vegas, NV and should be moving east today. We are going to have the same kind of scenario as yesterday. There appears to be an outflow boundary from Amarillo to Pampa. We are targeting the southwest portion of this boundary as are chase target. Dryline is backing up in response to the pressure falls, thus, we believe the action area will probably be close to the Texas-New Mexico border. Target town is CLOVIS, NM.

11:41 761 Rt. 70 Southbound.

12:42 820 PAMPA- Rt. 60 SW towards Amarillo. Still socked in with low clouds. Indefinite ceilings. Southeast winds.

10:09 234 AMARILLO: Staying at the Econolodge.

TRIP TOTAL 11.5 hours, 531 miles

WHAT WE'VE LEARNED:As the upper low moved east, unidirectional flow evolved east of the low forcing the storms to race northward and evolve from tornadic to non-tornadic. In contrast, the storms that developed near the base of the trough (ie. south of Lubbock), remained under difluent flow aloft and stayed tornadic well into the evening. Once again, tail end charlie storms did far better at maintaining tornadic potential.
