| Brief Description: EVENT NARRATIVE: There was damage to agricultural equipment. A single wide mobile home that had tie down straps was completely destroyed and the undercarriage was carried approximately 40 yards. No injuries reported. EPISODE NARRATIVE: A sharp dry line moved west out of west Texas and became stationary over the far eastern plains on Sunday, May 23, 2010. Meanwhile, an unseasonably deep upper level low pressure system over the Great Basin was moving slowly east toward New Mexico. The combination of the upper level disturbance approaching New Mexico and extreme instability along the dry line set the stage for widespread severe weather from Quay County northeast into Union County. | |||||||||||
