The episode as NWS CLE wrote it up.
A low pressure system over the upper Midwest moved across the Great Lakes on June 18. Ahead of the low pressure system, a warm front moved over the area early on June 18 bringing temperatures into the mid-80s that afternoon. A cold front trailed the low pressure system and moved across the Great Lakes through the afternoon. Ahead of the cold front, several severe thunderstorms developed, including one storm that produced and EF-1 tornado in northern Stark County. Additional thundestorms dropped very heavy rainfall across the area, especially in the Akron Metro area, as rainfall flooded the Central Interchange and many roadways south of the city.
National Weather Service Survey Team decided an EF-1 tornado touched down in Uniontown near the Uniontown Fire Department and traveled east southeast along an intermittent path for approximately 9 miles through Lake Township. Most of the damage observed was to trees that were uprooted or snapped part of the way up of the ground. A newly constructed dairy barn in Marlboro township near State Route 44 and St. Peters Church Road had significant roof damage. Minor roof and siding damage was observed along the tornado path. A swath of straight line wind damage occurred south of the tornado track from the north side of Canton to Louisville. Numerous trees and power poles were brought down, with at least one tree falling on a home. Several people were trapped in an SUV due to the downed power poles.

NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jun 18, 3:49 PM EST, 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 449 PM EDT THU JUN 18 2015 .SYNOPSIS... A COLD FRONT WILL DROP SOUTHEAST ACROSS THE AREA THIS EVENING THEN WEAK HIGH PRESSURE WILL QUICKLY CROSS THE AREA ON FRIDAY. A LOW WILL MOVE UP THE OHIO VALLEY SATURDAY THEN A COLD FRONT WILL PUSH SLOWLY SOUTHEAST THROUGH THE REGION SUNDAY THEN A SERIES OF UPPER LEVEL TROUGHS WILL AFFECT THE AREA NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... SEVERE THUNDERSTORM WATCH 311 ISSUED FOR THE WESTERN PORTIONS OF THE FORECAST AREA FOR THIS EVENING. THUNDERSTORMS CONTINUE TO DEVELOP ACROSS THE AREA AT THIS TIME. LARGE AREA OF THUNDERSTORMS OVER INDIANA HEADED EAST TOWARD THE FORECAST AREA AND THIS IS THE ACTIVITY THAT WE WILL BE CLOSELY MONITORING FOR SEVERE WEATHER. SECOND ISSUE IS HOW MUCH RAIN WE GET IN THESE STORMS. WILL NEED TO MONITOR FOR FLOODING ISSUES ESPECIALLY IN THE SOUTHWEST. WILL HANDLE THIS THREAT WITH ANY NEEDED FLOOD/FLASH FLOOD WARNINGS AS NEEDED. PREVIOUS DISCUSSION... A COLD FRONT WILL SLOWLY MOVE SE ACROSS THE AREA TONIGHT COLLIDING WITH A MOIST AND UNSTABLE AIRMASS TO PRODUCE NUMEROUS SHRA/TSRA. THERE APPEARS TO NOT BE ENOUGH WIND SHEAR FOR SEVERE STORMS BUT AN ISOLATED ONE HERE OR THERE IS POSSIBLE. QPF SHOULD STAY LIGHT ENOUGH MOST PLACES TO NOT LEAD TO FLOODING BUT THERE WILL STILL PROBABLY BE A FEW LOCATIONS THAT GET HEAVY RAIN LONG ENOUGH FOR SOME LOCAL FLOODING TO DEVELOP. PREFERRED TO HAVE HIGHER AMOUNTS OF QPF EARLY TONIGHT BUT COLLABORATION WOULD NOT ALLOW FOR THIS. COOLER AIR PUSHING IN LATER WILL LEAD TO COOLER TEMPS THAT LAST NIGHT WITH LOWS MOSTLY IN THE LOW TO MID 60S. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/... HIGH PRESSURE IS EXPECTED TO BUILD IN ENOUGH FOR FRI TO PUSH THE BETTER MOISTURE SOUTH. HOWEVER...THE 12Z MODEL RUNS ARE STARTING TO COME AROUND TO THE IDEA THAT THE HIGH TO THE NORTH WILL NOT BE STRONG ENOUGH TO FLUSH ALL THE MOISTURE OUT OF THE SOUTH. THEREFORE...WILL SHOW MORE POP IN THE SOUTH ON FRI. HIGHS WILL BE COOLER THAN NORMAL NEAR THE LAKE DUE TO A NE FLOW OFF THE LAKE. THE HIGH WILL SHIFT OFF TO THE EAST FRI NIGHT AND A RETURN FLOW FROM THE SOUTH WILL SET UP BRINGING TROPICAL MOISTURE INTO THE AREA FOR THE WEEKEND. NOT SURE HOW MUCH PRECIP WILL SPREAD ACROSS THE AREA LATE FRI NIGHT. MORE WIDESPREAD SHRA/TSRA WILL SPREAD OVER THE AREA ON SAT THEN HANG AROUND THRU SUN UNTIL A COLD FRONT DROPS SE ACROSS THE AREA. RIGHT NOW THE MODELS ARE TRYING TO KEEP THE REMNANTS OF THE TROPICAL LOW IN SOUTHERN OHIO WITH THE HEAVIER QPF THERE. NOT QUITE READY TO BUY OFF ON THIS AND DISMISS THE POSSIBILITY OF LOCALLY HEAVY RAIN AND POTENTIAL FLOODING. SOMEWHAT DRIER AIR WITH WEAK HIGH PRESSURE MOVES IN FOR SUN NIGHT SO THERE MAY BE LITTLE TO NO SHRA ACTIVITY EVEN THOUGH A WEAK UPPER TROUGH IS EXPECTED TO BE CROSSING THE REGION. && .LONG TERM /MONDAY THROUGH THURSDAY/... THE LONG TERM BEGINS ON MONDAY WITH MODELS SHOWING A SHORT WAVE MOVING ESE THROUGH THE GREAT LAKES AND OHIO VALLEY WITH VERY LITTLE SURFACE REFLECTION. MANUAL PROGS SHOW A STATIONARY FRONT ACROSS SOUTHERN OHIO. FOR NOW WILL HAVE CHANCE POPS FOR THE DAY AND THROUGH THE NIGHT. TUESDAY AND WEDNESDAY HIGH PRESSURE TRIES TO BUILD IN FROM THE NORTH BUT STILL WITH ENOUGH MOISTURE IN THE AREA WILL LIKELY NEED AT LEAST LOW CHANCE POPS THROUGH THE REMAINDER OF THE PERIOD. ON BALANCE TYPICAL SUMMER WX. HIGHS WILL BE SEASONAL. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... MVFR TO LOW VFR CONDITIONS ACROSS THE AREA THIS AFTERNOON. WARM FRONT IS APPROACHING ERIE AND IS NORTH AND EAST OF THE REMAINDER OF THE AREA. THE AREA AIRMASS IS QUITE MOIST WITH DEWPOINTS IN THE UPPER 60S TO LOWER 70S. EXPECTING SCATTERED AFTERNOON CONVECTION TO DEVELOP WITH CAPES FORECAST TO REACH 1600-2000+J/KG WITH LITTLE OR NO CAP. COULD SEE MORE OF A SOLID AREA OF CONVECTION DROP DOWN WITH THE APPROACHING COLD FRONT LATE AFTERNOON/EARLY EVENING BEGINNING IN THE NORTHWEST. OVERNIGHT EXPECTING WIDESPREAD MVFR AND AREAS OF IFR CIGS AND VISIBILITIES ALTHOUGH PRECIP THREAT SHOULD END 02-04Z AS COLD FRONT DROPS SOUTH. OUTLOOK...NON VFR LIKELY SATURDAY INTO SUNDAY IN SHOWERS AND THUNDERSTORMS. && .MARINE... NO HEADLINES EXPECTED THROUGH THE PERIOD ALTHOUGH NEAR SMALL CRAFT CONDITIONS POSSIBLE LATE TONIGHT/EARLY FRIDAY. COLD FRONT WILL DROP SOUTHEAST ACROSS THE LAKE THIS EVENING WITH WINDS TURNING NORTH/NORTHWEST BEHIND THE FRONT AT AROUND 15 KNOTS. THIS WILL PUSH WAVE UP ON THE SOUTH SHORE. FOR NOW WILL GO WITH 2 TO 4 FEET. HIGH PRESSURE WILL BUILD IN FROM THE NORTH ON FRIDAY HOWEVER SO THE HIGHER WINDS AND WAVES WILL BE SHORT LIVED. WINDS WILL REMAIN GENERALLY LIGHT AND VARIABLE THROUGH SATURDAY. SUNDAY LOOK FOR SOUTHWEST FLOW AT 10 TO 15 KNOTS OR SO AS A WEAKENING COLD FRONT DROPS ACROSS THE LAKE. GENERALLY LIGHT FLOW RETURNS FOR SUNDAY NIGHT AND MONDAY. BEST CHANCE FOR THUNDERSTORMS WILL BE EARLY TONIGHT WITH THE COLD FRONT...AS WELL AS SATURDAY NIGHT AND SUNDAY AS REMNANTS OF A TROPICAL SYSTEM MOVE THROUGH THE OHIO VALLEY. && .CLE WATCHES/WARNINGS/ADVISORIES...
