After a long haul from Blacksburg to Conway Arkansas on the first day, we departed from our lodging stop in Arkansas in order to potentially intercept storms in the Red River Region of Texas/Oklahoma. We knew it would be a long-distance running intercept (on a similar long-distance chase in 2010 we intercepted a tornadic supercell after driving from I-40 in Arkansas, so we have done this before) and some degree of luck would have to be on our side as storms would have to fire in a reachable area.
Diving southwest of Oklahoma City toward Lawton we intercepted a severe-warned cell which later became tornado warned, but opted to continue southward in an effort to reach storms forming in a more unstable environment. We intercepted a tornadic storm just north of Grandfield Oklahoma in the southwestern part of the state just north of the Red River which forms the border with Texas. We knew the order of the day would be messy high-precipitation supercells with poor visibility, and that is what we got. Our long-distance travel hampered our ability to maneuver to the southern side of the storm as we had to approach it from the north. With limited road options (side roads with washouts due to heavy flooding continue to be an issue throughout the southern plains this year) we jabbed at the storm from various vantage points, as spotters confirmed a tornado with the storm. At one point we were close to the storm, but rain shrouded the base of the storm, hiding the tornado(s) from view. We continued to flank the storm on limited roads, finally opting for a second storm to the south after the Grandfield storm eventually began to form a small bowing line.
Our day did not end with these two storms, as another storm formed after dark shortly after we checked into our lodging stop for the night. With radar running and students analyzing the storm, we drove south of the projected path in order to see if we could get a visual on the nighttime tornado. Once again, heavy rain prevented clear viewing. After a long two hours we returned to our rooms for the night having logged a 10-hour drive followed by a 5-hour chase. An exhausting first day, but a good experience with a couple of HP supercells.
