A well-defined cold front plowed into South Central Nebraska on this Monday afternoon and evening, driven by a seasonably strong mid level shortwave trough tracking across the Northern Plains region. Storms initially fired up along the cold front during the early evening, generally along a line from near Alma to Grand Island to Fullerton. Around the time of storm initiation, the mesoscale environment featured around 2000 J/kg mixed-layer CAPE, but only around 25 knots of deep-layer vertical wind shear, resulting in slow storm motion along the southeast-moving surface front. This slow storm motion teamed with high precipitable water values around 2 inches to produce several pockets of locally very heavy rainfall and some flooding. In fact, over 5 inches of rain fell in southeast Adams County near Ayr and Pauline, which caused water to flow over Highways 74 and 281 for a short time. The Little Blue River at Deweese went into flood as well. Other pockets of heavy rain between 3-5 inches were reported in parts of Clay, Franklin and Thayer Counties. While very little severe weather occurred with these storms, there was one report of estimated 60 MPH winds at Kenesaw in Adams County.
