| Time | Report | Where | Remark |
|---|---|---|---|
| Jun 2, 2:00 AM EDT | HAIL 0.75 | Girard, PA |
Local storm reports filed while the alert was in force, from inside its polygon or its counties.
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
Buffalo Intl Airport, NY (KBUF), launched 00:00Z, 5.9 hours before the alert went out and 149 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.

KIELTYKAWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 2, 1:13 AM EDT, 40 minutes earlier.
Area forecast discussion, Jun 2, 1:13 AM EDT, 40 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 113 AM EDT TUE JUN 2 2009 .SYNOPSIS... A COLD FRONT OVER THE CENTRAL GREAT LAKES WILL MOVE SOUTH ACROSS THE LOCAL AREA TONIGHT AND THEN STALL. THE FRONT WILL MOVE BACK NORTH AS A WARM FRONT LATE TUESDAY AND THEN BACK SOUTH AS A COLD FRONT WEDNESDAY AS AN AREA OF WEAK LOW PRESSURE MOVES EAST ACROSS THE REGION. HIGH PRESSURE WILL THEN BUILD OVER THE REGION FROM THE NORTH THE REMAINDER OF THE WEEK. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... SHOWERS AND THUNDERSTORMS WILL CONTINUE OFF AND ON THROUGH THE NIGHT AS FRONT SETTLES AND STALLS ACROSS NORTHERN OHIO. SEVERE POTENTIAL WANING...BUT WILL HAVE TO MONITOR FLOODING POTENTIAL AS MORE UPSTREAM MODERATE RAIN WILL BE MARCHING EASTWARD. WARMED LOW TEMPERATURES A BIT ACROSS THE SOUTH...BUT STILL ALLOWED FOR MID 50S ACROSS NORTH WITH FRONTAL PASSAGE. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/... THE COLD FRONT WILL BECOME STATIONARY JUST SOUTH OF THE AREA TOMORROW. NE FLOW BEHIND THIS FRONT WILL TEMPORARILY DRY THINGS OUT. WILL LEAVE IN SOME HIGH CHANCE POPS FOR THE MORNING HOURS TO COVER ANY LEFT OVER MCS ACTIVITY...BUT EXPECT MOST OF THE AFTERNOON TO BE DRY...ESPECIALLY ACROSS FAR NE OH AND NW PA. THE FRONT WILL WIGGLE BACK NORTH LATE IN THE DAY AS WEAK LOW PRESSURE RIDE EAST ALONG THE FRONT. EXPECT ANOTHER MCS TO DEVELOP WITH MORE RAIN FOR THE AREA. HOPEFULLY THINGS WILL NOT GET OUT OF HAND. TOMORROW NIGHT MAY ACTUALLY BE A LITTLE BIT BETTER SET UP FOR HEAVY THAN TONIGHT. A DECENT 45 KNOT LOW LEVEL JET SHOULD GET GOING TOMORROW EVENING WITH GOOD OVERRUNNING OVER THE BAROCLINIC ZONE. THE DEVIL IS IN THE DETAILS THOUGH...AND UNTIL WE KNOW EXACTLY WHERE THE FRONT WILL BE...ANY TALK OF FLOOD WATCHES WILL HAVE TO WAIT. SEVERE WEATHER COULD ALSO BE A CONCERN WITH THE INCREASING LOW LEVEL SHEAR LATE TUESDAY. THE FRONT WILL FINALLY PUSH WELL TO THE SOUTH OF THE AREA ON WEDNESDAY. BOTH THE NAM AND GFS SHOW ONE LAST WAVE OF PRECIP HITTING THE AREA IN THE MORNING WITH DRYING LATE IN THE AFTERNOON AND EVENING. HIGH PRESSURE WILL TRY TO ESTABLISH ITSELF OVER THE AREA FOR THE END OF THE WEEK. WILL TRY FOR DRY WEATHER BOTH THURSDAY AND FRIDAY. TEMPS DURING THE PERIOD WILL AVERAGE BELOW NORMAL. HAVE USED A BLEND OF GUIDANCE FOR THE NEXT COUPLE OF DAYS. && .LONG TERM /FRIDAY THROUGH MONDAY/... MODELS IN DECENT AGREEMENT FOR THE EXTENDED FORECAST. STORM SYSTEM WILL MOVE ACROSS ONTARIO INTO QUEBEC ON SATURDAY WHICH WILL PUSH A FRONT INTO NORTHERN OHIO AND NW PA. THIS BOUNDARY WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS BEGINNING LATE SATURDAY. A RIPPLE OF LOW PRESSURE WILL THEN MOVE FROM THE PLAINS ALONG THIS BOUNDARY AND CONTINUE RAIN CHANCES INTO SUNDAY AND MONDAY. AT THIS POINT IT DOES NOT LOOK LIKE AN ALL DAY RAIN FOR ANY OF THE DAYS WITH SCATTERED SHOWERS AND THUNDERSTORMS ANTICIPATED. CLOUD COVER AND THE SCATTERED SHOWERS/THUNDERSTORMS MAY LIMIT THE HEATING BUT TEMPERATURES WILL STILL BE NEAR SEASONAL LEVELS. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... DIFFUSE WEAK COLD FRONT WILL SLOWLY SAG SOUTH ACROSS REST OF TAF SITES THROUGH DAYBREAK. WIND BEING DRIVEN MORE BY OUTFLOW FROM STORMS BUT AS MORE OF THE STORMS DISSIPATE SHOULD SEE LIGHT FLOW FROM THE N SET UP MOST SITES BY 12Z AND CONTINUE FROM THE NE THROUGH TUE. WILL DEAL WITH THUNDER IN TAFS FOR NEXT FEW HOURS BASED ON WHERE ACTIVITY IS CURRENTLY ONGOING OR IMMINENT. MODELS STAY WITH TREND OF DEVELOPING LOWER CLOUDS AND FOG LAST FEW HOURS OF THE NIGHT SO WILL STAY WITH FORECAST FOR THIS WITH BKN IFR OR LOW END MVFR CIGS DEVELOPING. SOMEWHAT DRIER LOW LEVEL AIR PUSHING S INTO AREA TUE SHOULD IMPROVE THE CIGS AND VSBYS TO VFR OR HIGH END MVFR ALTHOUGH THE FURTHER INLAND SITES FROM MFD TO YNG MAY BE SLOW TO IMPROVE. WITH DAYTIME HEATING SCT SHRA/TSRA PROBABLY WILL DEVELOP INLAND BUT EXPECTED COVERAGE LOW ENOUGH TO KEEP OUT OF INLAND TAFS FOR NOW. OVERRUNNING NATURE OF THE AIRMASS WILL PROBABLY BE STRONG ENOUGH TO KEEP SOME CONVECTION GOING TUE NIGHT...ESPECIALLY SOUTHERN HALF OF AREA. OUTLOOK...PERIODS OF MVFR/IFR POSSIBLE INTO WEDNESDAY IN LOW CLOUDS AND SHOWERS/THUNDERSTORMS. THURSDAY AND FRIDAY VFR. && .MARINE... WINDS TURN TO THE NE TUESDAY AS A COLD FRONT...NOW ACROSS THE CENTRAL LAKES WILL PUSH SOUTH OF LAKE ERIE AND THEN STALL. A LOW IS EXPECTED TO TRACK ALONG THE FRONTAL BOUNDARY NEAR LAKE ERIE TUE NIGHT. THE EXACT TRACK OF THE LOW IS STILL UNCERTAIN ENOUGH TO DETERMINE WHETHER OUR WATERS ON LAKE ERIE WILL SEE A VEERING OR BACKING SCENARIO. FRONT FINALLY PUSHES WELL SOUTH OF THE AREA WED WITH A NORTH FLOW SETTING UP. WILL BE NEAR SMALL CRAFT ADVISORY CRITERIA AS SOME WIND SPEEDS APPROACH 10 TO 20 KNOT FLOW AS COLDER AIR MOVES ACROSS THE LAKE. FLOW DECREASES BY END OF WORK WEEK AS HIGH PRESSURE MOVES OVER THE LAKE. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE.
