The episode as NWS CLE wrote it up.
A cluster of showers and thunderstorms developed over Lake Erie ahead of a cold front moving south across the Lake. These thunderstorms produced damaging winds as they moved onshore into Lake and Geauga Counties. Trees and powerlines were brought down by thunderstorm winds in Willoughby and Mentor, continuing inland to near Chardon in Geaugu County.
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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
806 PM EDT MON JUL 7 2014
.SYNOPSIS...
A WEAK FRONT WILL PUSH SOUTHEAST ACROSS THE FORECAST AREA TONIGHT.
LOW PRESSURE WILL MOVE ACROSS THE CENTRAL LAKES TUESDAY DRAGGING A
SECOND COLD FRONT ACROSS THE AREA. HIGH PRESSURE WILL MOVE OVER
THE AREA THURSDAY.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
UPDATED TO ADJUST THE WORDING TO SCATTERED SHOWERS AND
THUNDERSTORMS MOST LOCATIONS. SOME SHOWERS AND THUNDERSTORMS WERE
MOVING IN FROM THE LAKE BUT THEY SHOULD NOT LAST THAT LONG...SO
SCATTERED SHOULD HANDLE IT.
PREVIOUS DISCUSSION...
SCATTERED TSRA DEVELOPING FROM EXTREME NW PA TO NEAR MARION
MAINLY ON OUTFLOW FROM CONVECTION THIS MORNING. MARGINAL
INSTABILITY WITH CAPES HOVERING AROUND 1000 J/KG...AND WITH ABOUT
25-30 KTS OF SHEAR BELOW 1KM. LUCKILY FOR US THE BEST SHEAR IS TO
OUR EAST AND THE BETTER INSTABILITY IS TO OUR SOUTH. ALL THAT SAID
EXPECT TSRA COVERAGE TO INCREASE THIS EVENING AND THEN PUSH SE OF
THE AREA. HOWEVER...EXPECT ANOTHER LINE OF TSRA TO DEVELOP CLOSER
TO THE FRONT...WHICH IS NOW ACROSS SE LOWER MICHIGAN...AND THEN
MOVE ACROSS THE AREA LATER THIS EVENING. DOUBTS AS TO HOW
WIDESPREAD THIS CONVECTION WILL BE WITH THE LOSS OF DAYTIME
HEATING AND SINCE THE LL JET WILL LIFT NE OF THE FORECAST AREA
LATER THIS EVENING.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/...
ON TUESDAY...LOW PRESSURE NOW SOUTHERN PLAINS...WILL MOVE ACROSS THE
CENTRAL LAKES DRAGGING A SECOND COLD FRONT ACROSS THE AREA
TOMORROW. MODELS IN GOOD AGREEMENT WITH LOW NW UPPER MICHIGAN BY
DAYBREAK TUESDAY. WILL CONTINUE TUESDAY FORECAST WITH CATEGORICAL
POPS...STARTING IN THE WEST TOMORROW MORNING AND MOVING INTO THE
EASTERN HALF OF THE FORECAST AREA TOMORROW AFTERNOON. THINK BETTER
CHANCE FOR CONVECTION TOMORROW AFTERNOON IN THE EAST. MODERATE
INSTABILITY WITH CAPES NEARING 2000 J/KG. ALSO HAVE AN UPPER LEVEL
SHORT WAVE MOVING ACROSS LOWER LAKES IN ADDITION TO THE FRONT.
THINGS SHOULD STABILIZE QUICKLY BEHIND THE FRONT HOWEVER. COULD
SEE SOME LINGERING SHOWERS ON WEDNESDAY BEFORE HIGH PRESSURE FINALLY
BUILDS OVER THE AREA ON THURSDAY USHERING IN COOLER AND DRIER
CONDITIONS.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK A TROUGH WILL DEEPEN
ACROSS THE GREAT LAKES. ALTHOUGH IT DOES NOT LOOK BE A COMPLETE
WASHOUT...WILL HAVE A WEEKEND WITH SHOWERS/THUNDERSTORMS IN THE
FORECAST. HIGH PRESSURE FRIDAY WILL SHIFT EAST. A FRONTAL BOUNDARY
WILL LAY ACROSS THE GREAT LAKES THROUGH THE WEEKEND...AND FINALLY
PUSH SOUTH OF OUR AREA ON MONDAY. DETAILS DIFFER AMONGST THE MODELS
AND ONE OF THE WEEKEND DAYS MAY BE WETTER THAN THE OTHER.
TEMPERATURES WILL BE SEASONABLE AND DEPENDENT UPON CLOUD COVER...BUT
UPPER 70S THROUGH MID 80S WILL WORK.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
A FEW AREAS OF SHOWERS AND THUNDERSTORMS REMAIN THIS EVENING
ASSOCIATED WITH A WEAK FRONT DROPPING SOUTH INTO THE AREA. AS OF 00Z
ONE CLUSTER WAS LOCATED OVER CENTRAL LAKE ERIE AND ONE WEST OF
FDY. THE AREA OVER LAKE ERIE IS EXPECTED TO DRIFT SE WITH TIME AND
MAY IMPACT CLE BEFORE 02Z. OTHERWISE THESE ARE EXPECTED TO SHRINK
WITH TIME AND BE THE END OF THE CONVECTION FOR TONIGHT. HIGH
DEWPOINTS MAY RESULT IN SOME RESTRICTION TO VISIBILITY OVERNIGHT
WITH VISIBILITIES DROPPING TO AROUND 4SM. WE WILL HOLD ONTO 5-8
KNOTS OF WIND OUT OF THE SOUTHWEST THOUGH SO DENSE FOG SEEMS
UNLIKELY.
ANOTHER MORE ROBUST AREA OF LOW PRESSURE WILL APPROACH FROM THE WEST
ON TUESDAY MORNING. THERE IS A GOOD CHANCE OF SHOWERS AND
THUNDERSTORMS AT ALL OF THE TAF SITES WITH THE POTENTIAL FOR SOME OF
THE STORMS TO BE STRONG...MAINLY IN NE OH/NW PA DURING THE
AFTERNOON. BROUGHT VCTS INTO TOL/FDY TOWARDS 15Z AND APPROACHING CLE
BY 17Z. TIMING WILL NEED TO BE REFINED AS STORMS APPROACH ON
TUESDAY. SW WINDS WILL BE BREEZY WITH GUSTS ABOVE 20 KNOTS AT
TIMES...SHIFTING TO MORE WESTERLY WITH THE PASSAGE OF THE TROUGH.
OUTLOOK...NON VFR LIKELY IN SHRA/TSRA TUE NIGHT WITH LESSER
CHANCE IN THE SNOWBELT ON WED.
&&
.MARINE...
WILL KEEP THE SMALL CRAFT ADVISORY GOING AS IS...UNTIL 10P WEST AND
3A EAST. SOUTHWEST FLOW WILL KEEP 3 TO 5 FOOTERS IN THE NEARSHORE
WATERS THIS EVENING. SCATTERED THUNDERSTORMS WILL ALSO BE A THREAT.
A WEAKENING COLD FRONT WILL SETTLE SOUTH OF THE LAKE OVERNIGHT.
ANOTHER COLD FRONT WILL CROSS LAKE ERIE TOMORROW SO AGAIN SOUTHWEST
FLOW WILL PICK BACK UP TO 15 TO 20 KNOTS AND SHIFT WEST IN THE
EVENING. SMALL CRAFT ADVISORY POSSIBLE AGAIN. SHOWERS/THUNDERSTORMS
WILL ACCOMPANY THIS FRONT TOO. ONE MORE MINOR FRONT CROSSES ON
WEDNESDAY. THURSDAY AND FRIDAY WILL FEATURE HIGH PRESSURE OVERHEAD
AND THEREFORE GOOD LAKE CONDITIONS. THE HIGH WILL HAVE SHIFTED EAST
BY SATURDAY AND SOUTHWEST RETURN FLOW CAN BE EXPECTED.
