May Summary

Although severe weather was reported in southern Indiana or central Kentucky on six separate days this month, most of the reports were isolated and consisted of minor structural or tree damage. The strongest storms of the month dropped golf ball sized hail: one near Hartford on the 2nd and another in Butler County on the 29th. There were no tornadoes.

Though no record high temperatures were set, there was a remarkable string of very warm nights from the 19th to the 28th. Stubborn high pressure aloft over the southeast United States allowed warm temperatures to remain in place while the main storm track was to our west and north. We had just enough cloudiness and passing storms to prevent daytime readings from setting record highs at the main climate sites (though we occasionally came very close) while keeping us warm enough at night to set record warm lows.
