An upper level trough was to the west of the region as an upper level disturbance moved over the area. The atmosphere was unstable with upslope winds and plentiful moisture across the area. These conditions allowed for storms to develop with large hail and flash flooding. Storms were aided after sunset by an area of strong winds aloft that helped bring in moisture and contribute to lift.
