 Locally Heavy Rainfall:

A fairly weak upper level low pressure disturbance tracked across South Central Nebraska between the evening hours of Monday August 29, 2011, and the early morning hours of Tuesday, August 30th, generating a large area of thunderstorms. Despite considerable lightning across the area, no severe weather occurred with these storms. However, most areas near and especially south of Interstate 80 measured anywhere from 0.75 to 2 inches of rain, and locally much higher. Within the heart of the heaviest rain band, a stripe probably no more than 10 miles across received at least 2-4 inches of rain, with this band generally centered along a line from near Republican City - Upland - Blue Hill - Clay Center. A few of the highest measured rainfall totals from NWS cooperative observers and NeRAIN volunteers can be found in the table below.  

Although widespread flooding did not occur, localized areas of flooding were noted, including along the Thompson Creek near Riverton in Franklin County.
