A strong cold front tracked across eastern Kansas during the afternoon and evening hours of September 30th.  Strong southwesterly sustained winds of 25 to 35 mph with gusts up to 50 mph ahead of the main trough knocked down weak branches in Ottawa County.  Cloud cover during the morning hours prevented widespread and robust convection from developing as the cold front surged across the region.  But, sufficient heating and favorable vertical wind profiles allowed for a broken line of thunderstorms to develop right around the noon hour CST.  Thunderstorm wind gusts ravaged the far east central portion of the state, knocking down tree branches and power lines during the evening.  Small hail was also reported with some of the more intense storms.
