A cold front moved south out of the Texas panhandle on May 6th, and was draped across north Texas on the 7th and 8th. The front stalled across the northwestern sections of north Texas and combined to produce severe thunderstorms including large hail, tornadoes, and flash flooding. Flash flooding across Cooke County caused significant impacts, including a late night train derailment.
