A strong and slow moving upper level low pressure system brought severe storms for a second consecutive day across the region. Strong instability developed again during the afternoon hours among strong deep layer wind shear. Isolated storms initially developed by mid afternoon along a warm front oriented from west to east from the eastern South Plains through the northern Rolling Plains. A few of these storms quickly became severe with supercell structures, two of which produced tornadoes that caused no damage.
