|Jay and I continued to follow this storm south during the mid to late|
evening hours southeast of Rolla, KS into the Oklahoma panhandle north
of Guymon. The sequence of images shown here span about 20 minutes or
so from about 8:15 to 8:40pm showing the striated structure of the
high-based updraft as we were near the Oklahoma-Kansas border. New
storms were forming farther to the west which would eventually put on
an amazing cloud-to-ground lightning show in the saturated twilight
(see Part 3 below).
