April Summary

April was an active month, with many rounds of showers and thunderstorms. The most significant event of the month took place on the 2nd-3rd when an east-west line of heavy thunderstorms lined up along the length of the Ohio River. Four to six inches of rain fell along the I-64 corridor from Hoosier National Forest through Louisville to Lexington. Flash flooding was widespread, and many area rivers went out of their banks.

On the 7th-8th another band of heavy rain set up in almost the same place, with one to three inches of rain falling along I-64. By mid-month many locations were already experiencing a top ten wettest April and were dealing with extensive flooding.

Five of the first nine days of the month experienced severe weather in the form of large hail and damaging winds. On the 7th, baseball sized hail struck Garrard County and EF-0 tornadoes touched down in Madison County and Perry County.

The second half of the month was much quieter. The most impactful system in the second half of the month was a series of strong thunderstorms that dropped large hail on parts of central Kentucky, including 3" diameter hail in Danville. Also, a squall line pushed through southern Kentucky with strong winds and two small tornadoes.
