A thunderstorm complex that developed north of low pressure in north central Kansas merged with thunderstorms that developed north of a warm front that was along the Kansas and Nebraska border.  With temperatures in the 70s and dew point temperatures around 70 near the front and low, instability was moderately high.  Initially the thunderstorms that developed north of the warm front produced a few large hail reports.  However, as the storms to the west merged with the activity farther east the main severe weather reports consisted of strong winds, especially from one cluster of storms that rolled from Saline and Gage county east into the southeast corner of Nebraska.  Around 12,000 customers lost their power from the storm, mostly from Lincoln and locations southwest through southeast of town.
