The episode as NWS TOP wrote it up.

Thunderstorms developed along a dry line/frontal boundary in central Kansas during the afternoon hours of the 24th. These storms pushed eastward as the day progressed. Shear profiles indicated a threat for tornadoes during the day, but hail up to 0.88 in diameter were the only local reports received over the course of the event. Storms continued to push eastward throughout the evening, and although the threat for severe weather continued, no additional reports were received.

THE SEVERE THREAT OVERNIGHT DOES NOT APPEAR AS HIGH AS SFC LOW DROPS
SOUTHEAST INTO SOUTHERN KS AND DRY SLOT ADVANCES NORTHEAST INTO
PORTIONS OF THE CWA AS FRONT TO THE NORTH BEGINS TO ADVANCE BACK
