Kentucky Climate Summary
By: Tom Priddy, UK Agricultural Weather Center - 09/25/2018

This past week added to an already wet month for the Bluegrass State. Starting out, the remnant low of Florence drifted north across the eastern border of Kentucky on Monday. Light to moderate showers continued to fall across primarily the eastern half of the state, before the system moved out of the area that night. Summer heat and isolated afternoon storms then returned the next few days. Highs jumped into the low to middle 90s, much above normal highs of upper 70s to low 80s for this time of year. With that said, a strong cold front passed through the area Friday and Friday night. Ahead and along the boundary, thunderstorms developed within an unstable atmosphere, even forming a line at one point, producing gusty winds and heavy rain. While cooler temperatures arrived for the first day of fall on Saturday, the frontal passage signaled the start of a very active weekend in which several rounds of showers pushed through the state. Steady moderate showers even led to substantial flooding across portions of the Southern Bluegrass. Overall, the state averaged 1.75 inches over the past 3 days and 2.19 inches for the week.

Temperatures for the period averaged 75 degrees across the state which was 8 degrees warmer than normal and 4 degrees warmer than the previous period. High temperatures averaged from 86 in the West to 81 in the East. Departure from normal high temperatures ranged from 5 degrees warmer than normal in the West to 2 degrees warmer than normal in the East. Low temperatures averaged from 66 degrees in the West to 67 degrees in the East. Departure from normal low temperatures ranged from 9 degrees warmer than normal in the West to 13 degrees warmer than normal in the East. The extreme high temperature for the period was 99 degrees at MADISONVILLE 4S and the extreme low was 57 degrees at ALEXANDRIA 5NW.

Precipitation (liq. equ.) for the period totaled 2.19 inches statewide which was 1.36 inches above normal and 263% of normal. Precipitation totals by climate division, West 1.48 inches, Central 2.29 inches, Bluegrass 2.46 inches and East 2.52 inches, which was 0.63, 1.38, 1.71 and 1.7 inches above normal.
