Showers and thunderstorms developed out over portions of north central and northeast Kansas just before 5pm the evening of September 6th. The storms congealed into a complex that raced across portions of southeast Nebraska, Iowa, northeast Kansas, and northern Missouri during the overnight hours. This occurred out ahead of a cold front that dove across the Central Plains through the night. This complex of storms produced damaging thunderstorm winds and large hail across northeast Kansas. There was also a report of a funnel cloud early Thursday evening. A text version of all severe reports can be found by visiting our Local Storm Reports page.
