As the light set on Easter Sunday, isolated thunderstorms were already hours old off to the west of Dawson County and to the south in Kansas. The atmosphere wasn't done yet however.
Around 9:15 p.m. a squall line formed just over Lexington and proceeded eastward. Under an inch of rain was proceeded by pea sized hail which fell for several minutes.
The precipitation did not last long but the lightning did. Negatively charged lightning, commonly known as cloud to cloud lightning, lit up the night sky as the squall line departed.
Negatively charged lightning occurs as negative charge is transferred between the ground and the clouds. These type of strikes make up 90 percent of all lightning occurrences and are less dangerous than positively charged bolts.
