What happened
The episode as NWS MRX wrote it up.
A continuation of severe weather from the previous day involved convection which developed early in the day in association with an overnight outflow boundary followed by the main event involving a meso-scale convective system driving southeast into a moderately to highly unstable air mass. An amplifying upper level trough building east through the Ohio Valley added sufficient wind energy for strong and organized storm development. Late in the day into the evening, more storms developed ahead of the system cold front as it moved southeast toward the Southern Appalachian region.
What forecasters said that day

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 936 AM EDT TUE JUL 14 2015 .DISCUSSION...SORT OF LIKE THE WAY THE HRRRR HANDLES THE AFTERNOON CONVECTIVE SHOW. THIS MODEL SEEMS TO UNDERSTAND THAT MORNING CONVECTION THAT IS CURRENTLY RAKING OVER SOUTHWEST VIRGINIA AND NORTHEAST TENNESSEE COULD SUFFICIENTLY STABILIZE THE ATMOSPHERE IN THIS REGION TO KEEP ANY STORMS FROM BECOMING SEVERE. HOWEVER FARTHER WEST AND SOUTH WHERE DEWPOINT TEMPERATURES ARE IN THE LOWER 70S...THE ACTION COULD BE LIVELIER. ALSO...THERE DOESN'T APPEAR TO BE QUITE AS MUCH CLOUD MASS INHIBITING INSOLATION ACROSS WESTERN AND CENTRAL SECTIONS OF KENTUCKY CLOSER TO WHERE THE NEW DAY'S STRONG TO SEVERE CONVECTION MAY BUBBLE UP AS THE LAKES SHORT WAVE DRIVES SOUTHEAST TOWARD THE OHIO VALLEY. AFTER CHECKING OUT POPS IN THE GRIDS IT LOOKS LIKE THEY ARE SET UP WELL FOR WATCHING THE MORNING ACTION FADE AWAY TO THE SOUTHEAST WHILE AWAITING EXPECTED AFTERNOON THROUGH EVENING CONVECTION BUILD BACK ACROSS THE SOUTHERN APPALACHIAN REGION. CAPES AROUND 3000-4500 J/KG ALONG WITH 35-40 KNOTS OF SHEAR SHOULD LEAD TO SEVERE THUNDERSTORM DEVELOPMENT WITH THE MAIN THREAT BEING STRAIGHT LINE WIND WITH A MINOR THREAT FOR AN ISOLATED TORNADO. && .MRX WATCHES/WARNINGS/ADVISORIES...
