Kentucky Monthly Weather Summary

For the Period: September 2017 Slightly Above Normal Temperatures and Above Normal Rainfall: Kentucky saw two tropical systems pass through the area over the first half of September. The remnants of Hurricane Harvey arrived over the first couple days of the month, brining widespread moderate to locally heavy showers. Rainfall was most prevalent across Central Kentucky where several locations recorded over five inches. The high amount of rainfall in a short period of time led to numerous flood warnings. The remnants of Hurricane Irma then followed on the 12th and 13th, bringing on and off light showers. Unlike the extremely high rainfall totals seen with Harvey, the state only averaged three quarters of an inch with Irma. The rain and cloud cover associated with both systems led to a cool first half of the month. In fact, after the second week of September, the Bluegrass State had gone four straight weeks of temperatures averaging below normal. The rest of the month turned mostly dry. In fact, most of the state did not receive any rainfall over the last week of September. Still, Harvey brought more than enough rainfall to push Kentucky to a seventh straight month of above normal rainfall. Along with the dryness, heat returned over the latter half of September. Even though the 22nd signaled the official start of fall, the third week of September had highs routinely rise into the middle 80s to low 90s.
