The forecast was for large CAPEs, jet cirrus moving eastward, and a
frontal boundary; all in southwest Kansas setting the stage to produce
We departed OKC at 2004 UTC along with the Electra. We found the ground teams in Sitka, KS under a band of Sc. We setup an east-west INIT pattern over Sitka, observing only a windshift boundary at 500'AGL. After climbing above the clouds at 8000'AGL, we observed new convective growth near Garden City and proceeded to the new targets. We began radar legs at 2209 UTC. Growth was rapid with a hook observed on the LF at 2233UTC. First tornado was reported by PROBE 1 at 2335 UTC. We also observed the tornado at 2345 UTC. Several funnels were observed by the ground teams as well as aircraft personnel. A second tornado was reported by the ground teams at 0139 UTC near Burdett, KS after the FC had cancelled operations at 0132 UTC. We continued radar legs until 0205 UTC. There was some anxious moments as the ground chasers became the chasee as PROBE 1 escaped northward with the tornado in hot pursuit.
We performed 33 Doppler legs on the supercell which appears to be great data. We returned to OKC at 0255 UTC consuming 7.1 hours. We now have 40.4 hours remaining.
