March Summary

April Summary

May Summary

Spring got off to an exciting start as a cyclone with record low barometric pressure brought hurricane force winds and record rainfall to parts of the Ohio Valley, including Louisville, on the third day of the (meteorological) season. March then ended with a major tornado outbreak in the Midwest and South, and though a small, brief tornado touched down on the far east side of Louisville, the worst of the weather stayed to our north and south.

Louisville continued to be a magnet for short-lived tornadoes when several more struck the area on April 5 and May 7. On May 8 golf ball sized hail pummeled Shively and Louisville International Airport around 3:40 in the morning.

While temperatures were near normal for the season as a whole, a precipitation deficit was recorded throughout central and eastern Kentucky and extreme southern Indiana. By the end of the season D0 ("abnormally dry") conditions had developed.
