Severe Thunderstorms and Heavy Rain, 9/6-9/7

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.

Heavy rain caused problems across northeast Kansas Thursday night as well.  Several flood and flash flood warnings were issued, primarily for counties along the Nebraska border where the heaviest precipitation fell.  Several roads were inundated with water and closed.  An estimated summary of rainfall across northeast Kansas last evening appears below.  Data is preliminary and should not be used for official purposes.

The Black Vermillion River at Frankfort and the Turkey Creek at Seneca both rose above flood stage overnight. The Black Vermillion was still above flood stage early Friday afternoon, while the Turkey Creek had fallen below.  The Big Blue River at Blue Rapids is expected to rise to flood stage later this afternoon. For more information on river forecasts for northeast Kansas, please visit our local Hydrology page.
