Overview
|
A slow-moving upper level shortwave trough advancing out of the Mississippi Valley and subtle waves of low pressure riding along an attendant surface cold front led to multiple rounds of stormy weather on July 2nd, 2023. Though shear was only marginally sufficient, plenty of strong early July sunshine over Kentucky (on the warm side of the front) led to a highly unstable environment which fueled rounds of intense and particularly photogenic thunderstorms. The first severe thunderstorms reached the Southeastern Bluegrass and Red River Gorge areas by around 5 PM with locally intense winds. The most substantial wind damage was reported in the Levee area of Montgomery County where multiple structures sustained wind damage and many trees were snapped. An official NWS Storm Survey determined that the winds were straight-line and not tornadic. Sizable power outages were also reported in Montgomery and Menifee counties with these storms. The first cluster of storms generally weakened as they crossed the Licking River basin and departed through the Big Sandy River basin. A second line of storm organized over Central Kentucky and moved into Eastern Kentucky around and after 8 PM. The strongest portions of the second line generally impacted locations to the south of the Mountain Parkway. Overall intensity of the thunderstorms diminished during the mid and late evening with the loss of heating and increasing low-level stability. By the time storms came to an end, the National Weather Service in Jackson had received more than 60 reports of severe weather, primarily in the form of wind damage. |

Environment
The surface analysis (Figure 1) showed multiple weak waves of low pressure tracking along a cold front making painfully slow progress into the Lower Ohio Valley. On the warm side of the front, multiple clusters of thunderstorms developed and initiated multiple outflow boundaries which moved toward the Appalachians and disintegrated.

The primary threat with the storms turned out to be wind. Dry air aloft, evidenced by DCAPE (Figure 6) values largely in excess of 900 J/kg, was supportive of the generation of strong rain-cooled downdrafts. Fairly steep low-level lapse rates (Figure 7) favored those downdrafts reaching the surface and leading to damaging wind gusts. Thus it is not surprising that dozens of instances of wind damage were reported across eastern Kentucky.
