Three distinct rounds of severe weather affected South Central Nebraska, starting during the early morning hours, and lasting into the post-midnight hours of June 2nd. The first round flared up during the early morning hours as elevated thunderstorms became severe in a strengthening low level jet axis. These storms produced hail up to golf ball size between Highway 6 and the Kansas state line. Following a mid-day lull, a second round of severe thunderstorms initiated during the late afternoon hours as a surface cold front moved in from the north, colliding with a very unstable airmass featuring CAPE values of 3000-4000 J/kg and deep-layer shear of 40-50 knots. These storms mainly affected far eastern portions of the area, from Nance County southward along the Highway 81 corridor into York and Fillmore Counties with isolated large hail, locally heavy rainfall, and gusty outflow winds. Finally, the third and final round of severe thunderstorms, with isolated large hail, overspread parts of south central Nebraska south of Interstate 80 during the late evening and very early morning hours of June 2nd.
