What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|

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 tornado 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 (KAGC), launched 12:00Z, 10.5 hours before the alert went out and 83 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.

NWS Pittsburgh, PA wrote its last area forecast discussion before this tornado warning went out at Jun 11, 2:54 PM EDT, 3 hours 36 minutes earlier.
Area forecast discussion, Jun 11, 2:54 PM EDT, 3 hours 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 254 PM EDT THU JUN 11 2015 .SYNOPSIS... WELL ABOVE NORMAL TEMPERATURES WILL CONTINUE WITH A CHANCE OF THUNDERSTORMS BEGINNING FRIDAY AFTERNOON AS A COLD FRONT TRANSITIONS ACROSS THE REGION. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... SO FAR TODAY WARMER AIR ALOFT HAS CAPPED OFF ANY CONVECTION...BUT OPTED TO MAINTAIN A SLIGHT CHANCE OF THUNDERSTORMS MAINLY NORTH OF INTERSTATE 80 THROUGH EARLY EVENING WHERE A FRONTAL BOUNDARY RESIDES AND HAVE RECENTLY OBSERVED SEVERAL SMALL CELLS POP UP TO AROUND 18KFT OR SO WHERE A SECOND INVERSION WAS OBSERVED IN THIS MORNINGS SOUNDING. OVERNIGHT...NO ACTIVITY IS ANTICIPATED WITH LOSS OF SFC BASED INSTABILITY AND THE SURFACE BOUNDARY LIFTS BACK NORTH AS FLOW RETURNS TO THE SOUTHWEST. OVERNIGHT LOWS WILL AGAIN BE WELL ABOVE NORMAL...BUT SLIGHTLY LOWER THAN OBSERVED LAST NIGHT UNDER LESS CLOUD COVERAGE. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... A FAIRLY LEAN MOISTURE PROFILE WILL RESIDE OVER THE AREA FOR THE MAJORITY OF THE DAY ON FRIDAY...WITH DEEPER MOISTURE REMAINING TO THE NORTHWEST OF THE CWA INTO THE AFTERNOON HOURS. THIS WILL ALLOW FOR INCREASING SOUTHWESTERLY FLOW TO MIX TO THE SURFACE WITH AMPLE INSOLATION THROUGH THE AFTERNOON HOURS. BECAUSE OF A VERY WARM LIKELY START TO THE DAY...THIS SHOULD ALLOW FOR DRY ADIABATIC MIXING FROM ABOVE 850 MB TO THE SURFACE. WITH MODEL PROJECTIONS SUGGESTING 18 TO 19C AT 850 MB...LOW 90S WILL LIKELY BE IN PLAY IN MOST LOCATIONS IN THE CWA. STRONG MIXING IN THE PRE-FRONTAL ENVIRONMENT MAY ALLOW FOR EVEN STRONGER TEMPERATURE RISES SHOULD DRY AIR ALOFT GET ENTRAINED. HOWEVER...SHOULD THIS OCCUR...DEWPOINTS WILL LIKELY FALL OFF A BIT MORE THAN EXPECTED. REGARDLESS...THE CURRENT EXPECTATION IS THAT DEWPOINTS SHOULD HANG AT LEAST IN THE MID 60S...WHICH WOULD RESULT IN HEAT INDEX VALUES RUNNING IN THE MID 90S...WHICH WOULD EASILY BE THE HIGHEST VALUES SO FAR THIS YEAR. THE COLD FRONT SLIDES SOUTH TOWARD AND THROUGH THE AREA BY FRIDAY EVENING AND NIGHT...WITH EVENING CAPE VALUES RUNNING TOWARD 2500 J/KG. THE CAP AROUND 15 KFT STILL DOES LOOK TO EXIST ON MODEL SOUNDINGS...THOUGH NOT TO THE DEGREE IT HAS FOR THE PAST COUPLE OF DAYS. HOWEVER...WITH ADDITIONAL LARGE SCALE FORCING FOR ASCENT ALONG THE FRONT IN THE RIGHT ENTRANCE REGION OF THE UPPER JET...SHOWERS AND THUNDERSTORMS WILL BECOME LIKELY INTO THE EVENING AS INSTABILITY STARTS TO WANE. DUE TO THE TIMING AFTER THE DIURNAL INSTABILITY MAXIMUM...IT WOULD SEEM SEVERE THUNDERSTORMS WILL BE A BIT HARDER TO MUSTER...HOWEVER ONE OR TWO MAY GUST OUT DURING THE EVENING. COOLER AIR WILL FOLLOW THE FRONT ON SATURDAY AS IT PUSHES INTO THE SOUTHERN CWA...THEN STALLS. SHOWER CHANCES WILL REMAIN ACROSS THE SOUTH AS THIS OCCURS AND IT STARTS TO MOVE BACK NORTHWARD AGAIN ON SUNDAY. THIS WILL MEAN JUST A BRIEF RESPITE FROM THE HOT/HUMID CONDITIONS ON SATURDAY...WITH MUGGIER AND WARMER AIR AGAIN RETURNING ON SUNDAY. FRIES && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... INITIALLY WARM TEMPERATURES AND HUMID CONDITIONS UNDER EASTERN CONUS RIDGING ARE EXPECTED TO BE ALLEVIATED SOMEWHAT BY MIDWEEK AS THE FRONT SAGS SOUTHWARD/RIDGE ERODES VIA SHORTWAVE DREDGING. CHANCE PRECIP NUMBERS WERE MAINTAINED THROUGHOUT THE PERIOD...BUT GUIDANCE NUMBERS WERE TEMPERED GIVEN PROJECTIONS OF WARMTH ALOFT AND TIMING QUESTIONS. NEVERTHELESS...THE BETTER CHANCE OF RAIN FOR THE LONG TERM PERIOD LOOKS TO BE ON TUESDAY WITH THIS MORNING MODEL RUNS...BUT HAVE OPTED AGAINST LIKELY POPS FOR NOW GIVEN THE LACK OF MODEL CONSISTENCY AND COLLABORATION NECESSITIES. WPC GUIDANCE GENERALLY DEPICTED THE SITUATION WELL AND FEW CHANGES WERE NEEDED OUTSIDE OF THE POPS DISCIPLINE. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... VFR CONDITIONS EXPECTED TODAY WITH A SLIGHT CHANCE OF A THUNDERSTORM OR TWO NORTH OF THE I-80 CORRIDOR THROUGH EARLY EVENING IMPACTING KDUJ OR KFKL. .OUTLOOK.../THURSDAY NIGHT THROUGH MONDAY/... THE NEXT CHANCE FOR GENERAL RESTRICTIONS IS ANTICIPATED WITH A FRIDAY NIGHT/EARLY SATURDAY COLD FRONT. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
