The episode as NWS MEG wrote it up.
Scattered thunderstorms developed during the early afternoon hours on June 26, 2015. These storms formed in a moist and unstable airmass ahead of an approaching cold front. A few of these storms were severe with winds greater than 58 mph. Eventually the storms congealed into a line of thunderstorms that pushed across West Tennessee during the early evening hours. Several of these storms were severe with damaging winds.
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 Memphis, TN wrote its last area forecast discussion before the first event at Jun 26, 11:18 AM CST, 2 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 1218 PM CDT FRI JUN 26 2015 .UPDATE... UPDATED TO INCLUDE THE 18Z AVIATION DISCUSSION BELOW. JCL && .DISCUSSION... /ISSUED 1027 AM CDT FRI JUN 26 2015/ SKIES ARE MOSTLY SUNNY ACROSS THE FORECAST AREA THIS MORNING WITH TEMPERATURES IN THE 80S. SURFACE BOUNDARY CURRENTLY EXTENDS FROM CENTRAL INDIANA THROUGH SOUTHWEST MISSOURI AND INTO NORTHEAST OKLAHOMA. SHOWERS AND THUNDERSTORMS ARE MOVING THROUGH SOUTHWEST MISSOURI AT THE MOMENT. THUNDERSTORMS WILL EVENTUALLY MOVE INTO THE FORECAST AREA LATER THIS AFTERNOON AND INTO THIS EVENING. SOME OF THESE THUNDERSTORMS MAY PRODUCE DAMAGING WINDS WITH THE BEST CHANCE OF SEVERE WEATHER OVER NORTHERN SECTIONS OF THE FORECAST AREA. WILL UPDATE FORECAST TO REMOVE SOME MORNING WORDING. ARS PREV DISCUSSION... /ISSUED 626 AM CDT FRI JUN 26 2015/ AN ACTIVE WEATHER PATTERN IS SETTING UP ACROSS THE MID SOUTH TODAY WITH THE POTENTIAL FOR SEVERE THUNDERSTORMS LATER THIS AFTERNOON THROUGH TONIGHT. AN UNSEASONABLY POTENT UPPER LEVEL SHORTWAVE POSITIONED OVER THE CENTRAL PLAINS THIS MORNING WILL CONTINUE TO ADVANCE SOUTHEASTWARD THROUGH THE REMAINDER OF TODAY THROUGH THE FIRST PART OF THE WEEKEND. THIS WILL HELP TO PUSH A SIGNIFICANT COLD FRONT THROUGH THE REGION TONIGHT INTO SATURDAY MORNING. INITIALLY...A MESOSCALE CONVECTIVE SYSTEM ORGANIZED ACROSS NORTH-CENTRAL MISSOURI AT DISCUSSION TIME WILL MOVE SOUTHEAST...FORCED BY A DEVELOPING ORGANIZED CONVECTIVE COLD POOL. THIS MCS MAY REACH NORTHERN PORTIONS OF THE FORECAST AREA THIS MORNING. MUCH OF THE LATEST CONVECTIVE ALLOWING SHORT TERM MODEL GUIDANCE WEAKENS THIS COMPLEX AFTER SUNRISE AS IT OUTRUNS BETTER DYNAMIC FORCING TO THE NORTHWEST AND LOW LEVEL FLOW WEAKENS. THIS WILL BE MONITORED CLOSELY TO ENSURE IT DOES NOT CONTINUE ON THROUGH THE MORNING HOURS. FURTHER SOUTH ACROSS THE REMAINDER OF THE MID SOUTH...DAYTIME HEATING COMBINED WITH A SEASONABLY MOIST AIRMASS AND WEAK HEIGHT FALLS ALOFT SHOULD SUPPORT DIURNALLY ENHANCED SCATTERED SHOWERS AND THUNDERSTORMS...MAINLY THIS AFTERNOON. STRONGER DYNAMIC FORCING WITH NOTABLE MID LEVEL HEIGHT FALLS ON THE ORDER OF 60DM WILL SURGE INTO NORTHERN PORTIONS OF THE MID SOUTH EARLY THIS EVENING. NUMEROUS THUNDERSTORMS SHOULD DEVELOP LATE THIS AFTERNOON ALONG THE SOUTHEASTWARD SURGING CONVECTIVELY INFLUENCED COLD FRONT ACROSS NORTHERN SECTIONS OF THE REGION. THESE STORMS SHOULD DEVELOP IN AN UNSTABLE AIRMASS AS MLCAPES APPROACH 3000 J/KG WITH MID LEVEL LAPSE RATES BETWEEN 6.5-7.0C/KM PRIOR TO CONVECTIVE OVERTURNING OF THE ATMOSPHERE. IN ADDITION...LOW AND MID LEVEL WIND FIELDS SHOULD INCREASE EARLY THIS EVENING ALONG AND SOUTH OF A DEVELOPING SURFACE WAVE THAT SHOULD RACE EASTWARD ALONG THE FRONT FROM EASTERN MISSOURI ACROSS THE LOWER OHIO VALLEY OVERNIGHT. THE COMBINATION OF MID LEVEL HEIGHT FALLS...A MODERATELY UNSTABLE AIRMASS...AND MODEST SHEAR ON THE ORDER OF 30 TO 40 KTS...SHOULD SUPPORT A SEVERE WEATHER THREAT WITH A STRONGLY FORCED CONVECTIVE LINE OF STORMS MOVING SOUTH TOWARDS THE INTERSTATE 40 CORRIDOR DURING THE EVENING HOURS...AND SOUTH OF I-40 AFTER MIDNIGHT. IT APPEARS THAT SUFFICIENT DYNAMIC FORCING...MODEST SHEAR...AND A WARM/MOIST LOW LEVEL AIRMASS SHOULD ALLOW THE SEVERE THREAT TO PERSIST WELL INTO THE OVERNIGHT HOURS. AT THIS TIME...IT APPEARS THAT THE PRIMARY SEVERE WEATHER THREAT WILL BE DAMAGING WINDS...WITH THE POTENTIAL FOR AN ENHANCED CORE OF WINDS ASSOCIATED WITH ANY FORWARD PROPAGATING MESOSCALE CONVECTIVE SYSTEM (MCS). THIS IS SUPPORTED BY THE PRIMARILY UNIDIRECTIONAL FLOW OF WINDS THROUGH THE ATMOSPHERE. AN ISOLATED TORNADO ALONG THE FAR NORTHERN SECTIONS OF THE AREA CANNOT BE RULED OUT IN CLOSER PROXIMITY TO THE SURFACE LOW...BUT THE GREATER TORNADO THREAT SHOULD REMAIN NORTH OF OUR AREA AND WILL LEAVE ANY MENTION OUT OF THE HAZARDOUS WEATHER OUTLOOK FOR NOW. THE COLD FRONT AND ASSOCIATED STORMS SHOULD SWEEP SOUTH TO FAR SOUTHERN PORTIONS OF THE FORECAST AREA BY SUNRISE WITH ALL AREAS DRY BY SATURDAY AFTERNOON. A MUCH COOLER AND LESS HUMID AIRMASS WILL FILTER SOUTH BEHIND THE FRONT WITH VERY PLEASANT SUMMER WEATHER CONDITIONS EXPECTED FROM SATURDAY AFTERNOON THROUGH SUNDAY. RETURN SOUTHWESTERLY LOW LEVEL FLOW WILL BECOME RE-ESTABLISHED BY EARLY NEXT WEEK WHICH WILL QUICKLY MODIFY THE AIRMASS AND SUPPORT A MOISTENING ATMOSPHERE AS EARLY AS NEXT MONDAY. THE MID SOUTH SHOULD REMAIN FIRMLY ENTRENCHED IN NORTHWEST FLOW ALOFT THROUGH MUCH OF NEXT WEEK. THIS SHOULD OCCUR AS BLOCKING RIDGES OVER THE NORTH ATLANTIC AND MUCH OF THE WESTERN U.S. REMAINS IN PLACE. A SERIES OF UPPER LEVEL SHORTWAVES MOVING SOUTHEAST ACROSS THE AREA IN THE FLOW ALOFT WILL SPARK CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGH MUCH OF THE EXTENDED FORECAST PERIOD. TIMING AND INTENSITY ISSUES WILL NEED TO BE WORKED OUT AS WE MOVE CLOSER IN TIME TO ANY PARTICULAR MCS EVENT. BELOW AVERAGE TEMPERATURES ARE EXPECTED TO PERSIST THROUGH MUCH OF NEXT WEEK. JLH && .AVIATION... 18Z TAF CYCLE (26/18Z-27/18Z) MOSTLY VFR CONDITIONS WILL OCCUR FOR MUCH OF THIS AFTERNOON OUTSIDE SCATTERED THUNDERSTORM DEVELOPMENT. WINDS THIS AFTERNOON SW 10-12 KTS WITH GUSTS TO 18 KTS EXCEPT WINDS AT KTUP WESTERLY 8 KTS. WIDESPREAD SHOWERS AND THUNDERSTORMS WILL MOVE INTO THE AREA FROM THE NORTHWEST BY LATE THIS AFTERNOON AHEAD OF A COLD FRONT AND MOVE ACROSS THE AREA TONIGHT. CONDITIONS LOWERING TO IFR IN THE HEAVIER SHOWERS AND THUNDERSTORMS WITH STRONG AND GUSTY WINDS POSSIBLE. CONVECTION ENDING FOLLOWING PASSAGE OF THE COLD FRONT WITH MVFR CONDITIONS THROUGH SATURDAY MORNING...POSSIBLY IFR AT KJBR LATE TONIGHT AND EARLY SATURDAY MORNING. WINDS TURNING TO THE N TO NW WITH FRONTAL PASSAGE NEAR 12 KTS WITH GUSTS 17-20 KTS DEVELOPING MID TO LATE MORNING SATURDAY. JCL && .MEG WATCHES/WARNINGS/ADVISORIES... AR...NONE. MO...NONE. MS...NONE.
