Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Pittsburgh, PA (KPIT), launched 12:00Z, 9.0 hours before the alert went out and 174 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.SHORT TERM(TONIGHT THROUGH THURSDAY NIGHT)...
CDFNT EXTREME WESTERN OHIO MOVING SLOWLY EAST AND BY 12Z WILL BE
LOCATED FROM ERI TO HTS. LOW PRESSURE NEAR TORONTO WILL MOVE SLOWLY
NORTHEAST. A TROF LOCATED WEST TO EAST FROM THE LOW WILL ROTATE
SOUTH. THE COLD FRONT WILL CAUSE SHOWERS AND THUNDERSTORMS IN THE
EAST EARLY TONIGHT AND THE TROF WILL CAUSE SCATTERED SHOWERS AND
THUNDERSTORMS IN WEST. THE UPPER LOW THAT WILL BE MOVING ACROSS
SOUTHERN OHIO TONIGHT IS ALSO INVOLVED. VERY COLD AIR ALOFT ARE
MAKING THE LAPES RATES STEEP AS LEAST THROUGH THE AFTERNOON. AS THE
TROF SHIFTS EAST THAT WILL KEEP THE PRECIPITATION GOING TONIGHT. AT
THIS TIME WITH PLENTY OF CLOUD COVER ALL DAY THAT WAS HELPING THE
STORMS FROM NOT BECOMING SEVERE. SOME OF THEM HAVE BEEN CLOSE. IT IS
STILL POSSIBLE A FEW COULD BE SEVERE THROUGH THIS EVENING...HAIL
WOULD BE THE PRIMARY THREAT. THE BIGGER CONCERN IS SOME LOCALLY
HEAVY RAIN. WITH THE AIRMASS DRYING OUT ALOFT THAT SHOULD HELP KEEP
THE RAINFALL DOWN BUT CANT RULE OUT A FEW SPOTS APPROACHING THE
FLOOD GUIDANCE. MOST LOCATIONS WILL GET UNDER AN INCH...HOWEVER SOME
COULD BE UP TO 2 INCHES. THE TROF WILL MERGE WITH THE COLD FRONT
THURSDAY AND WITH THE TROF CLOSE SOME SHOWERS AND THUNDERSTORMS
COULD CONTINUE IN THE EAST ESPECIALLY IN THE AM AND EARLY AFTERNOON.
GFS AND WRF AGREE WITH THAT...THE WRF MAY BE A LITTLE QUICKER. THE
MODELS HANG UNTO THE MOISTURE SO THURSDAY WILL BE MOSTLY CLOUDY. THE
CLOUDS WILL DECREASE THURSDAY NIGHT FROM WEST TO EAST. WITH SOME
MOISTURE HANGING AROUND WILL JUST MAKE IT PARTLY CLOUDY.
&&

.LONG TERM(FRI-WED)...

TEMPERATURES ABOVE NORMAL. THE HIGH STARTS MOVING EAST SUNDAY NIGHT.
THE CONFLICT IS THE TIMING OF THE COLD FRONT. THE DIGEX IS QUICKER

GFS MONDAY NIGHT AND TUESDAY. THEN THE COLD AIR STARTS POURING IN.
THE ECMWF AND GFS WILL BRING IN COLD AIR AT 850 MB ON
WEDNESDAY...THE GFS HAS 0C AT 850 MB BY WEDNESDAY AFTERNOON. THIS
MAY BE ABOUT 5C TOO COLD WHICH TYPICALLY HAPPENS...ESPECIALLY SO FAR
OUT. WILL FORECAST SOME LAKE EFFECT CLOUDS AND A THREAT OF SHOWERS
TUESDAY NIGHT THROUGH WEDNESDAY.THE MODELS ARE TRYING TO FORECAST A
LOT OF LOW LEVEL MOISTURE WITH THIS IN AREAS OUTSIDE OF THE LAKE
EFFECT AREAS...THIS MAY BE OVERDOWN WILL FORECAST PARTLY CLOUDY.
