A stationary front was observed situated south of the Ohio River across northern Kentucky and West Virginia during July 26th when an upper level disturbance approached the state from the west late that evening. A 30 to 35 mph nocturnal low level jet developed just south of the boundary, tapping deep moisture in place across central Kentucky, carrying it northeast toward Greenbrier County, resulting in deep moisture convergence across the area. Precipitable water values were estimated to have risen from around 1.7 inches around 10 pm on the 26th to nearly 2 inches by around 6 am on the 27th, or two standard deviations above normal for late July. Given the latent heat of the tropical air being carried toward southeast West Virginia, most-unstable layer CAPE values were estimated to be between 500 and 1,000 J/Kg just after midnight on the 27th. Soils were already moistened from 0.5 to locally 1.5 inches of rain that fell during early afternoon on the 26th when another round of storms developed across the western part of the county beginning around 10 pm. Perhaps enhanced by upsloping as the storms entered the higher terrain across the western half of the county, the low-topped convection proved to be efficient, producing prolonged 1 to 2 inch per hour rainfall rates in multiple waves. The heaviest rainfall began to diminish by 5 am on the 27th, leaving only residual shower activity after dropping a large swath of 2 to over 4 inches within the 7 hour period.
