The episode as NWS CLE wrote it up.
Severe thunderstorms tracked from northeast Ohio into northwest Pennsylvania during the late afternoon hours as strong instability developed in the warm sector ahead of an approaching cold front. Energy moving through the flow aloft helped to kick off thunderstorms with severe winds causing downed trees in Edinboro. Multiple downed trees blocked one lane of Interstate 79 near Edinboro.

NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jul 23, 12:54 PM EST, 2 hours 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 154 PM EDT TUE JUL 23 2013 .SYNOPSIS... A COLD FRONT OVER THE WESTERN GREAT LAKES WILL MOVE ACROSS THE LOCAL AREA THIS AFTERNOON. CANADIAN HIGH PRESSURE WILL BEGIN TO BUILD OVER THE REGION FROM THE NORTHWEST ON WEDNESDAY. ANOTHER FRONTAL SYSTEM IS EXPECTED TO AFFECT THE REGION ON SATURDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... CONTINUING TO MONITOR LATEST RADAR AND SATELLITE TRENDS FOR EXPANSION OF CONVECTION THIS AFTERNOON. SHOWERS AND THUNDERSTORMS STARTING TO MOVE INTO THE NE LAKESHORE WITH ENHANCED CU FIELD EXTENDING SW ACROSS OHIO. MEANWHILE CLOUDS HAVE CLEARED OUT IN NW OHIO WITH SUBSIDENCE BEHIND THE SHORTWAVE. THE FORECAST HAS BEEN UPDATED TO REFLECT TRENDS WITH SCATTERED ACTIVITY STILL EXPECTED TO FILL IN ACROSS NE OHIO. GREATER UNCERTAINTY IS HOW THINGS WILL PLAY OUT IN THE WEST AS THE FRONT IN MICHIGAN APPROACHES LATER THIS AFTERNOON. SEVERAL OF THE HI-RES MODELS SHOW COVERAGE OF STORMS EXPANDING IN NRN OHIO AS THE STRONGER FRONTAL FORCING APPROACHES. STILL UNSURE ABOUT WHAT INFLUENCE THE DRIER MID- LEVEL AIR WILL HAVE ON THIS. EXPECTING IT TO BE A FEW HOURS BEFORE THE WESTERN COUNTIES SEE ANYTHING...BUT WILL CONTINUE TO CARRY A CHANCE AS WE WATCH THE EVOLUTION OF STORMS WITH THE FRONT. PREVIOUS DISCUSSION...REGIONAL RADARS SHOW SHOWERS MOVING INTO WESTERN LAKE ERIE ON THE LEADING EDGE OF THE DEEPER MOISTURE AS EVIDENCED BY THE 12Z DTX SOUNDING. THIS IS AHEAD OF THE ACTUAL COLD FRONT WHICH EXTENDS FROM NEAR THE SAGINAW BAY SW TOWARDS CHICAGO. ENOUGH HEATING IS EXPECTED TODAY FOR MODERATE INSTABILITY TO DEVELOP BY EARLY AFTERNOON WITH AN EXPANSION OF SHOWERS AND THUNDERSTORMS AS A SHORTWAVE MOVES THROUGH THE FLOW ALOFT. THIS WILL OCCUR OUT AHEAD OF THE ACTUAL FRONT WHICH IS NOT PROGGED TO ARRIVE IN NW OHIO UNTIL LATE AFTERNOON WITH DRIER AIR ALREADY WORKING INTO THE MID- LEVELS BY THAT POINT. THE STORM PREDICTION CENTER HAS EXPANDED THE SLIGHT RISK OF SEVERE THUNDERSTORMS BACK NORTH TO INCLUDE CENTRAL AND EASTERN OHIO...EXTENDING AS FAR NORTH AS MFD/CAK/YNG. 0-6KM SHEAR OF ONLY ABOUT 25 KNOTS WILL BE MARGINAL FOR ORGANIZED CONVECTION TODAY BUT INSTABILITY SHOULD BE SUFFICIENT FOR A FEW SEVERE STORMS FROM ANY STRONGER CLUSTERS THAT DEVELOP. STRONG WINDS AND HAIL WILL BE THE PRIMARY THREATS FOR TODAY. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/... WILL TRY TO END THE PRECIP FROM WEST TO EAST THIS EVENING. ALL OF THE NEW GUIDANCE SUGGESTING DRY WEATHER ALL AREAS BY 12Z. FORECAST SOUNDINGS SHOWING A DECENT LOW LEVEL INVERSION OVERNIGHT SO THE CLOUDS MAY BE TOUGH TO GET RID OF. DRY AIR WILL EVENTUALLY WIN OUT ON WEDNESDAY WITH RAPID CLEARING DURING THE MORNING HOURS. THERE WILL BE A DISTINCT AIRMASS CHANGE BEHIND THE COLD FRONT WITH DEWPOINTS FALLING THROUGH THE 50S. HAVE CONTINUED THE RECENT TREND OF LOWERING TEMPS A DEGREE OR TWO WITH EACH NEW MODEL RUN. TEMPS WEDNESDAY AND THURSDAY WILL BE WELL BELOW NORMAL. READINGS WILL BEGIN TO REBOUND ON SATURDAY. THE NEXT THREAT FOR PRECIP WILL COME AT THE VERY END OF THE PERIOD. A COLD FRONT WILL BEGIN DROP SOUTHEAST ACROSS THE GREAT LAKES FRIDAY NIGHT. WESTERN LOCATIONS HAVE A SHOT AT PRECIP BY 12Z SATURDAY. GIVEN THE CHANGING PATTERN HAVE NOT STRAYED TOO FAR FROM GUIDANCE TEMPS. && .LONG TERM /SATURDAY THROUGH MONDAY/... THE COLD FRONT STILL IS EXPECTED TO SLOWLY CROSS THE AREA SAT. COOLER AIR ARRIVING ALOFT WILL HELP WITH THE PRODUCTION OF SHRA AND TSRA WITH THE FRONTAL PASSAGE SAT. DRIER AIR ARRIVES FOR SUN BUT THE UPPER LOW MAY STILL BE STRONG ENOUGH FOR SOME INSTABILITY SHRA/TSRA TO OCCUR. ANY LINGERING CONVECTION SHOULD END IN THE EVENING THEN HIGH PRESSURE MOVING IN SHOULD PROVIDE DRY CONDITIONS FOR MOST OF SUN NIGHT THRU MON. TEMPS SHOULD TEND TO RUN A LITTLE BELOW NORMAL...ESPECIALLY ON SUN WHEN THE COOLEST AIR AT 850 MB SHOULD BE IN PLACE OVER THE CWA. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... TROUGH OF LOW PRESSURE OVER EASTERN OHIO WILL CONTINUE TO PRODUCE SHOWERS AND THUNDERSTORMS THIS AFTERNOON. THE COLD FROTN OVER SOUTHEAST LOWER MICHIGAN WILL ALSO GENERATE ADDTIONAL SHOWERS AND STORMS. THE CLUSTERS OF STORMS WILL LIKELY FILL IN OVER LAKE ERIE DURING THE LATE AFTERNOON AND ALL THE ACTIVITY WILL SLIDE OFF TO THE SOUTHEAST EARLY TONIGHT. UNFORTUNATELY...THIS WILL RESULT IN "TEMPO" FORECASTS FOR A RELAITVELY LONG PERIOD OF TIME...3-6 HOURS IN MOST FORECASTS. THE WIND WILL SHIFT FROM THE NORTH TONIGHT BEHIND THE COLD FRONT. SOME MVFR STRATOCUMULUS IS POSSIBLE LATER TONIGHT AND WEDNESDAY MORNING FOR PARTS OF NE OH/NW PA. .OUTLOOK...SHOWERS AND THUNDERSTORMS MAY CAUSE NON VFR CONDITIONS SATURDAY. && .MARINE... LIGHT WINDS WILL BEGIN TO INCREASE OUT OF THE WEST TODAY AS A COLD FRONT PASSES ACROSS THE LAKE THIS AFTERNOON. WINDS QUICKLY TURN TO THE NORTH THIS EVENING AND INCREASE TO ABOUT 15 TO 20 KNOTS CAUSING WAVES TO BUILD TO 2 TO 4 FEET AND POSSIBLE 3 TO 5 FEET SO A SCA COULD BE NEEDED FOR TONIGHT. HIGH PRESSURE BUILDS INTO THE LAKE FROM THE WEST WED INTO WED NIGHT AND DIMINISHES THE FLOW. THE HIGH WILL MOVE EAST OF THE LAKE BY FRI TO ALLOW A SOUTH FLOW TO DEVELOP. A COLD FRONT REMAINS ON TRACK TO PUSH ACROSS THE LAKE SAT AND SHIFT TO FLOW TO NW BUT WIND SPEEDS LOOK TO INCREASE TO ONLY 10 TO 15 KNOTS. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE.
