Featuring both a morning and evening round of severe thunderstorms, Saturday the 19th was one of the most active severe weather days of 2010 across parts of North Central Kansas. The first round of severe storms, in the form of a MCS, rolled from west to east across the area within a few hours after sunrise. This complex of storms first organized across Northeast Colorado and Southwest Nebraska shortly after midnight, before rolling east-southeast into North Central Kansas. These storms were slightly elevated, focusing along the nose of a low level jet, and slightly north of a nearly stationary, east-west surface front draped across Central Kansas. The synoptic environment featured considerable instability, with MUCAPE values of 3000-4000 J/kg, and deep-layer wind shear of 30-40 knots. These storms produced both large hail and damaging winds, with hail up to golf ball size reported in Phillips County, and wind gusts to around 65 MPH in both Phillips and Mitchell Counties. In the Cawker City and Glen Elder areas, there was tree damage and significant structural damage to at least one mobile home.
After a lull in the action that lasted most of the day, the second round of severe weather flared up during the late afternoon, lasting well into the evening hours. These storms focused directly along the east-west surface front, which had moved north during the day in response to deepening low pressure across the Central High Plains. Around storm initiation time, the environment was again very supportive of significant severe weather, with MLCAPE values around 4000 J/kg, and 40 knots of deep-layer wind shear. In addition, things were also becoming increasingly favorable for tornadoes, with 0-1 km storm-relative helicity climbing into the 200-300 m2/s2 range, and 0-1 km bulk shear of 20-25 knots. Given these parameters, storms started out as semi-discrete supercells, the strongest of which produced an EF1 tornado near Randall in Jewell County that damaged a farmstead. Although this was the only tornado reported during the evening, there were numerous reports of large hail, high winds and flooding rainfall as the initial storms merged into a nearly stationary east-west line that remained draped over parts of the area for several hours. Flash flooding resulted in water over several roads, with radar estimations of at least 5-7 inches of rain across parts of southern Phillips County and adjacent areas. The Bow Creek near the Phillips and Rooks County line rose more than 5 feet above flood stage, setting an all-time record crest of 14.29 feet.
