A strong upper level disturbance approaching from the northwest spawned a powerful squall line during the very early morning hours of June 1st. The squall line moved east to southeast across portions of south-central and southeast Kansas, producing high winds and flooding rains in its path. Portions of Sumner and Cowley Counties were hit particularly hard with 70 to 80 winds, which inflicted pockets of substantial property damage.
