The episode as NWS MRX wrote it up.
Scattered strong to severe thunderstorms formed along a slow moving cold front aligned along Interstate 75. The storms became severe due lifting along the boundary in a moderately to strongly unstable atmosphere across East Central and Southeast Tennessee.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Morristown, TN wrote its last area forecast discussion before the first event at Jun 1, 2:01 PM EST, 4 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 301 PM EDT MON JUN 1 2015 .SHORT TERM...(TONIGHT THROUGH TOMORROW NIGHT)...SHOWERS AND STORMS SHOULD DIMINISH IN STRENGTH THIS EVENING AS WE LOSE OUR DAYTIME HEATING. SPOTTY LINGERING SHOWERS AND A STORM OR TWO POSSIBLE THROUGH THE NIGHT. FOG LOOKS LIKE IT WILL BEGIN TO DEVELOP SHORTLY AFTER MIDNIGHT DUE TO EXPECTED PARTIAL CLEARING. PATCHY DENSE FOG EXPECTED LATE IN THE NIGHT AND THROUGH EARLY MORNING...ESPECIALLY ACROSS AREAS THAT RECEIVE RAIN. A WEAK AND SLOW MOVING FRONTAL BOUNDARY CONTINUES TO MOVE EAST SOUTHEAST ACROSS THE FORECAST AREA OVERNIGHT ALONG WITH THE INCOMING BROAD AND UPPER TROUGH. BOUNDARY LOOKS TO BE DRAPED ALONG THE SPINE OF THE APPALACHIANS BY EARLY TOMORROW MORNING AND GRADUALLY MOVE FURTHER EAST THROUGH THE DAY TOMORROW. FOR OUR AREA...THE FOCUS FOR SHOWER AND STORM ACTIVITY LOOKS TO BE ACROSS OUR EASTERN MOUNTAINS NEAR THE VICINITY OF THE BOUNDARY. ALSO...THE BROAD WEAK UPPER TROUGH IS FINALLY CENTERED OVER OUR AREA TOMORROW. THE CENTER OF THIS CLOSED OFF LOW LOOKS TO BE RIGHT ON TOP OF US. THIS POSITIONING...ALONG WITH THE BOUNDARY OFF TO OUR EAST...SHOULD HELP TO KEEP THE BEST COVERAGE OF SHOWERS AND STORMS OFF TO OUR EAST AS WELL. HOWEVER...THERE IS STILL ENOUGH LIFT AND MOISTURE ASSOCIATED WITH THE BROAD TROUGH THAT IT SHOULD BE ABLE TO GENERATE AT LEAST A FEW SHOWERS AND STORMS ACROSS THE AREA. SHOWER AND STORM ACTIVITY DIMINISH OVERNIGHT TUESDAY. .LONG TERM...(WEDNESDAY THROUGH MONDAY)...A CLOSED MID/UPPER LOW PRESSURE CENTER WILL BE NEARLY STATIONARY OVER THE SOUTHERN APPALACHIANS WEDNESDAY. DEEP MOISTURE OFF THE ATLANTIC OCEAN WILL WRAP AROUND THE LOW AND INTO OUR NORTHERN SECTIONS. AN INVERTED LOW LEVEL TROUGH AND 850 MB SPEED CONVERGENCE WILL SUPPLY SOME LIFT IN NORTHERN AREAS AS WELL...SO WILL HAVE LIKELY POPS NORTH FOR WEDNESDAY. LESS MOISTURE AND LIFT SHOULD MEAN LOWER PRECIP CHANCES CENTRAL AND SOUTH. THE LOW DRIFTS SLOWLY EASTWARD...AND BY THURSDAY...THE DEEP MOISTURE PLUME SHOULD BE TO OUR EAST AS THE 850-700 MB FLOW TURNS N-NW. THERE WILL STILL BE SOME LOW LEVEL MOISTURE AND INSTABILITY TO SUPPORT SCATTERED CONVECTION...AND WILL HAVE POPS IN THE CHANCE RANGE IN THE AFTERNOON. AS THE CLOSED UPPER LOW TRANSITIONS INTO AN OPEN TROUGH OVER THE CAROLINAS...IT CONTINUES ITS EASTWARD MOVEMENT...AND EAST TN WILL SEE A SERIES OF SHORTWAVE RIDGES AND TROUGHS MOVING THROUGH THE NW FLOW THROUGH THE REMAINDER OF THE FORECAST PERIOD. THE PROBLEM IS THAT THE MODELS ARE NOT IN GOOD AGREEMENT WITH THE TIMING OR INTENSITY OF THE SHORTWAVE TROUGHS...SO CONFIDENCE IS LOW IN THE DETAILS. AS A RESULT...THE FRIDAY THROUGH MONDAY PERIOD WILL BE BROAD BRUSHED WITH CHANCE POPS THAT MAINLY FOCUS ON A DIURNAL TREND OF HIGHER POPS DURING THE DAY AND TEMPERATURES NEAR NORMAL. && .PRELIMINARY POINT TEMPS/POPS...

ONGOING CONVECTION THIS AFTERNOON SHOULD BEGIN TO DIMINISH IN STRENGTH AND COVERAGE THIS EVENING AS WE LOSE OUR DAYTIME HEATING. UNTIL THEN...A FEW STRONG TO ISOLATED SEVERE STORMS ARE POSSIBLE AS A WEAK FRONTAL BOUNDARY REMAINS NEAR THE EASTERN TENNESSEE VALLEY AND SOUTHERN APPALACHIANS. THE BIGGEST THREATS APPEAR TO BE HEAVY RAINFALL AND GUSTY WINDS. HEAVY DOWNPOURS AND TRAINING OF STORM CELLS MAY CAUSE LOCALIZED FLOODING...ESPECIALLY IN LOW LYING AREAS. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY... THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE WEEK AS AN UPPER LEVEL LOW PRESSURE SYSTEM WILL FORM NEAR THE SOUTHERN APPALACHIANS AND HAVE LITTLE MOVEMENT THIS WEEK. A RISK OF LOCALLY HEAVY RAINFALL WILL EXIST WITH THIS SYSTEM DUE TO THE MOISTURE RICH ENVIRONMENT THAT WILL BE IN PLACE ACROSS THE REGION. SOME MINOR FLOODING CONCERNS CAN BE EXPECTED IN AREAS THAT RECEIVE PROLONGED RAINFALL FROM MORE THAN ONE ROUND OF SHOWERS AND THUNDERSTORMS. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME.
