April 2019 ended up much warmer and drier across eastern Kentucky. Jackson totaled 2.80" of

Both Jackson and London were two to three degrees above normal. Jackson saw the 11th warmest
April while London tied for the 16th warmest April.
Here are the April climate summaries and April Local Climatological Data reports for Jackson and London:
