The episode as NWS CLE wrote it up.
A strengthening low pressure system tracked northeast from southern Lake Michigan to eastern upper Michigan during the early morning hours of April 10. This system pushed a cold front east across the area with isolated wind gusts of 50 knots or more occurring along and behind the front. A wind gust to 52 knots was recorded at the Findlay Airport. At the same time strong wind gusts caused a tree to fall on a house in North Baltimore.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
149 AM EDT FRI APR 10 2015
.SYNOPSIS...
LOW PRESSURE WILL MOVE THROUGH THE CENTRAL GREAT LAKES TONIGHT AND
DRAG A COLD FRONT THROUGH THE AREA. A SECONDARY COLD FRONT WILL
DROP ACROSS THE AREA FRIDAY EVENING. HIGH PRESSURE WILL BUILD IN
FOR SATURDAY AND SUNDAY
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
LOW LEVEL JET SEEMS TO BE ASSISTING THE CONVECTION OVER THE
EASTERN END OF LAKE ERIE. A FEW OF THESE THUNDERSTORMS MAY CLIP
ERIE COUNTY PA. OTHERWISE WE WILL NEED TO WAIT FOR THE CONVERGENCE
ALONG THE FRONTAL BOUNDARY TO GET ADDITIONAL DEVELOPMENT. WE WILL
MONITOR DEVELOPMENT ACROSS SOUTHERN OHIO AND SEE IF IT CAN MOVE
INTO THE EASTERN HALF OF THE REGION AS WE APPROACH SUNRISE.
CONFIDENCE NOT HIGH ENOUGH TO GO WITH LIKELY POPS AT THIS POINT.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY NIGHT/...
FRIDAY MORNING 12Z THE COLD FRONT SHOULD BE JUST EAST OF KCLE WITH
DRYING MOVING IN FROM THE WEST. WILL HANG ONTO A CHANCE OF THUNDER
EAST THROUGH THE FIRST HALF OF THE MORNING BUT EXPECT PRECIP TO
END BY LATE MORNING. WILL ALLOW FOR SS TO BREAK THROUGH DURING THE
DAY BUT AM STILL A BIT SKEPTICAL GIVEN LOW LEVEL RH REMAINING
ACROSS THE AREA. ANOTHER BIG CONCERN FOR FRIDAY WILL BE WINDS.
850MB FLOW INCREASES TO 50 KNOTS ACROSS THE AREA LATE TONIGHT WITH
40-45 KNOTS AT 925MB. THIS CONTINUES POST COLD FRONT. AT THIS TIME
IT DOESNT LOOK LIKE WARNING LEVELS WILL BE REACHED BUT COULD
REQUIRE A WIND ADVISORY. IF THIS CONTINUES WILL LIKELY ISSUE ON
THE EVENING OR OVERNIGHT FORECAST PACKAGE. BOTH THE NAM AND GFS
CONTINUE TO SHOW A SECONDARY COLD FRONT/UPPER SHORT WAVE MOVING
THROUGH DURING THE EVENING AND EARLY OVERNIGHT FRIDAY NIGHT. WILL
BRING CLOUDS BACK AS WELL AS A SMALL CHANCE POPS. DRY AIR AND HIGH
PRESSURE BUILD IN FOR SATURDAY AND SUNDAY.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
MODELS GENERALLY AGREE WITH WEAK COLD FRONT PUSHING SE ACROSS THE
AREA MON SO WILL MAINTAIN DECENT THREAT FOR SHRA. THE FRONT IS SHOWN
TO MOVE FAR ENOUGH SOUTH OF THE AREA TO PROBABLY ALLOW FOR DRY
CONDITIONS ON TUE WITH WEAK HIGH PRESSURE OVER THE AREA. WED THRU
FRI...A SLOW MOVING UPPER LOW OVER THE PLAINS WILL DRIFT NE CAUSING
A LOW TO LIFT NE TOWARD LAKE MICHIGAN BY LATE FRI. THE STALLED
FRONT WILL SLOWLY LIFT NORTH INTO THE REGION AS A WARM FRONT
PROVIDING A FOCUS FOR SHRA AND TSRA TO START SPREADING NE OVER THE
AREA WED INTO WED NIGHT AND CONTINUE ON THU...AND PROBABLY FOR
SEVERAL MOVE DAYS AFTER THAT. TEMPS UNCERTAIN AS THE NORTHERN PART
OF THE CWA MAY SEE NE WINDS AHEAD OF THE FRONT THUS PRODUCING A COOL
FLOW OFF OF LAKE ERIE WHILE THE SOUTHERN COUNTIES HAVE A GOOD CHANCE
OF SEEING TEMPS WELL INTO THE 60S ANY MAYBE SOME 70S.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
SOMEWHAT ACTIVE COLD FRONT ACROSS INDIANA WILL MOVE ACROSS OH AND
PA TAF SITES DURING THE MORNING. THIS WILL BRING ONE LAST ROUND
OF SHRA/TS TO MOST...BUT POSSIBLY NOT ALL...TAF SITES. THE BEST
COVERAGE MAY BE FROM MFD UP THROUGH ERI AND POINTS EAST AS
ACTIVITY FROM SOUTHWEST OHIO/EASTERN INDIANA MOVES INTO CENTRAL
AND EASTERN OHIO JUST AHEAD OF THE FRONT. VFR OUTSIDE OF SHRA/TS
AND UNTIL THE COLD FRONT. THEN A SHORT PERIOD OF MVFR CEILINGS
BEFORE THOSE SCATTER OUT THIS AFTERNOON. WIND GUSTS WILL BE THE
PRIMARY CONCERN. GUSTS TO 25 KNOTS WILL BE COMMON FROM THE SSW
PRECEDING THE FRONT...BUT THEN AN UBRUPT SHIFT AND INCREASE TO 30
TO 40 KNOTS FROM THE WEST TO TAKE PLACE WITH THE FRONT ITSELF.
GUSTS WILL SETTLE TO 30 TO 35 KNOTS FROM THE WEST-SOUTHWEST FOR
THE REMAINDER OF THE AFTERNOON...BEFORE FURTHER DIMINISHING NEAR
DARK. SECONDARY TROUGH/COLD FRONT WILL BRING SOME MVFR CEILINGS
BACK INTO THE REGION OVERNIGHT ALONG WITH A FEW SHOWERS.
.OUTLOOK..SOME NON VFR POSSIBLE ACROSS NW PA FOR EARLY SATURDAY
MORNING. NON VFR POSSIBLE AGAIN FOR MONDAY.
&&
.MARINE...
A STRONG COLD FRONT SWEEPING ACROSS LAKE ERIE LATE TONIGHT AND
FRIDAY MORNING AND THE FOLLOWING COLD ADVECTION SHOULD BE ABLE TO
PRODUCE GALE FORCE WINDS FOR A WHILE. WILL GO WITH LOW END GALES FOR
A WHILE ON FRI. THE PRESSURE GRADIENT STARTS TO WEAKEN LATER
FRI INTO FRI NIGHT SO WINDS SHOULD SLOWLY START DIMINISHING THEN
BECOME LIGHT BY SAT EVE AS HIGH PRESSURE MOVES ACROSS OHIO INTO PA.
A RETURN SOUTHERLY FLOW SHOULD SET UP IN THE WAKE OF THE HIGH FOR
SUN INCREASING TO ABOUT 10 TO 20 KNOTS FOR SUN NIGHT AHEAD OF A WEAK
COLD FRONT THAT CROSSES THE LAKE MON. WEAK HIGH PRESSURE QUICKLY
BUILDS IN BY MON NIGHT SO WINDS WILL DIMINISH AND SHOULD STAY FAIRLY
LIGHT THRU TUE.
