October 2021 Summary

October was warm and wet throughout the Ohio Valley and much of the Midwest. Rain fell somewhere in the middle Ohio Valley on 27 days of the month.

Despite the warmth and frequent rains, severe weather was sparse. Only two days of the month experienced damaging thunderstorms. The most significant was on the evening of the 15th when two EF-0 tornadoes touched down in southern Indiana. The first skipped along a 2.7 mile path northeast of New Pekin in Washington County. The second twister was only on the ground for three-fifths of a mile, but moved right into Lexington in Scott County. Both tornadoes primarily caused tree damage. A couple of homes in Lexington had some minor roof damage.

On a much larger scale, the Climate Prediction Center issued a La Niña Advisory on the 14th, indicating that La Niña conditions have developed in the tropics of the Pacific and are expected to continue through the winter.
