Episode Narrative A warm front moved slowly north through Oklahoma, settling near the Oklahoma and Kansas border by mid afternoon. Scattered thunderstorms developed over western and northern Oklahoma, with another area of thunderstorms developing near the Red River. The thunderstorms produced large hail and heavy rain as they moved east and northeast. One thunderstorm, however, remained discrete and moved east and then east-southeast over north-central Oklahoma. Backed surface winds near the warm front helped maximize low-level wind shear, and three brief tornadoes developed over open country in Grant county. The storms over southwest Oklahoma weakened with the loss of daytime heating, but the northern Oklahoma storms merged into a complex. This complex continued well into the evening producing heavy rain.
