I hope you are staying cool and hydrated through this intense heat wave. While the individual days may come up a little short of criteria, who cares? The cumulative effect of day after day with heat index values in the triple digits is dangerous. Today is our 2nd day in the 90's and we still have 6 more to go. Lawrence, Jackson, Jennings and Carroll counties are now under the Extreme Heat Warning until Thursday at 8 pm. That's the expansion. The rest of our area, including Louisville, has seen an extension to the warning until Friday at 9 pm.
