Winds up to 80 mph Cause Damage In Prestonsburg & Far Eastern KY on May 29, 2019

Overview

The combination of an upper level impulse and southward sagging frontal boundary out of the Ohio Valley brought a line of strong to severe thunderstorms across eastern Kentucky during the late morning and afternoon of May 29, 2019. The most intense of these storms moved through far eastern Kentucky, including Prestonsburg where a 70-80 mph downburst blew half the roof off of a hock shop building.

A man driving on West Court Street was crushed by this roof, resulting in his death. Damage stretched for about 1 mile through the city. Severe winds blew out a few of the windows of a 2 story building on West Court Street, while a large healthy poplar tree was uprooted.

Elsewhere, from West Liberty and Jackson eastward through Pike County, mainly tree damage was sustained. In Letcher County, a rotating supercell produced quarter to golf ball sized hail near Jenkins, while Somerset experienced isolated damage from a thunderstorm wind gust on the southwest flank of the line of storms.

Environment


Day 1 Convective Outlook Issued by Storm Prediction Center (SPC) in Norman, OK.	8 pm Surface Analysis from Weather Prediction Center (WPC) in College Park, MD.


The DCAPE (Downdraft CAPE) can be used to estimate the potential strength of rain-cooled downdrafts (damaging wind potential) within thunderstorms. Larger DCAPE values are associated with stronger downdrafts. Values around 1000 are generally considered favorable for strong winds.	Surface Based Convective Available Potential Energy, showning the magnitude of instability.	Effective Bulk Shear, higher values suggest a greater potential for organized/sustained storms.
