A few thunderstorm clusters developed over northwest/north-central PA well in advance of a cold front crossing the lower great lakes region. Low-level lapse rates steepened in the wake of earlier clouds/precipitation, fostering the development of modest instability bolstered by middle-60s dewpoints.

The episode as NWS CTP wrote it up.
A few thunderstorm clusters developed over northwest/north-central PA well in advance of a cold front crossing the lower great lakes region. Low-level lapse rates steepened in the wake of earlier clouds/precipitation, fostering the development of modest instability bolstered by middle-60s dewpoints. As such, strong to severe storms produced isolated damaging wind gusts during the afternoon and evening hours.

NWS State College, PA wrote its last area forecast discussion before the first event at Jun 3, 10:47 AM EST, 3 hours 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1147 AM EDT TUE JUN 3 2014 .SYNOPSIS... SHOWERS AND THUNDERSTORMS WILL OCCUR THIS AFTERNOON AND EVENING IN ADVNACE OF A COLD FRONT MOVING EAST FROM THE UPPER GREAT LAKES. A DRY PERIOD SHOULD PREVAIL FROM TONIGHT INTO WEDNESDAY AS AN AREA OF HIGH PRESSURE SLIDES OVER THE REGION. A SEASONABLY STRONG LOW PRESSURE SYSTEM WILL TRACK FROM THE OHIO VALLEY INTO THE CENTRAL APPALACHIANS WEDNESDAY NIGHT INTO EARLY THURSDAY...AND MAY BE ACCOMPANIED BY A CONVECTIVE HEAVY RAIN COMPLEX. FAIR AND DRY WEATHER IS EXPECTED THROUGH SUNDAY NIGHT OR MONDAY. && .NEAR TERM /THROUGH TONIGHT/... 11 AM UPDATE... SHOWERS VERY LIGHT BUT CONSISTENT AS THEY MOVE TO THE EAST. CLOUDS BEHIND THE SHOWERS ARE BREAKING UP A LITTLE AND THERE ARE SOME SMALL SHOWERS STARTING TO SHOW UP ON THE RADAR OVER WRN PA AND OH. WILL CONTINUE TO MENTION SCT/NMRS SH/TSRA LATER THIS AFTN AND THIS EVENING AS THE REAL FRONT APPROACHES AND WE ARE STILL IN THE WARM SECTOR. 8 AM UPDATE... CHECKED THE LATEST HIGH RES MODEL OUTPUT WHICH SEEMS TO FIT THE CURRENT TRENDS. TWEAKED THE POPS SLIGHTLY IN THE NEXT 6-12 HRS TO SHOW PROGRESSION/DECAY OF THIS FIRST BUNCH OF SHOWERS...THEN REINVIGORATION OF THEM AS THEY HIT THE EASTERN COS. ALSO SHOWED A BIT OF A BREAK UNTIL THE SHRA/TSRA ASSOCD WITH THE ACTUAL FRONT ARRIVES THIS EVENING. SLIGHT TWEAKS TO SKY AS WELL. TEMPS/WINDS ALL ON TRACK. PREV... BAND OF MAINLY LGT SHOWERS WITH A FEW EMBDD LTG STRIKES EXTENDS FROM HLG NEWD ACRS NW PA...IN ASSOCIATION WITH PRE- FRONTAL/SFC TROUGH AND AXIS OF HI PWATS/35-40KT WSWLY LLJ. THE LATEST HIRES MDLS CONTINUE TO INDICATE THAT THIS BAND WILL INITIALLY WEAKEN AS IT CROSSES THE ALLEGHENY FRONT BTWN 12-15Z BUT THEN MAY RE-FIRE OVER THE ERN 1/3 OF THE CWA BY THE AFTN. THE MAIN SYNOPTIC COLD FRONT CROSSING LWR MI ATTM PER SFC TD ANALYSIS IS EXCEPTED TO IGNITE ADDNL SCT CONVECTION OVER WRN PA BY 16Z WHICH SHOULD ALSO SPREAD EWD AND EXPAND IN CVRG DURG THE AFTN. DESPITE DECENT ML CAPES AND MID-LVL LAPSE RATES...STORM INTENSITIES SHOULD GENERALLY REMAIN AOB SEVERE LIMITS GIVEN WEAK DEEP-LYR SHEAR AND BEST OVERALL FORCING/HGT FALLS DISPLACED TO THE NORTH. HOWEVER..STILL CANNOT RULE OUT AN ISOLATED STG TO MARGINALLY SVR PULSE TYPE STORM OR MULTI-CELL CLUSTER CAPABLE OF PRODUCING LOCALLY HVY RAFL WITH 1-1.5" PWAT. THE MAIN FROPA SHOULD TAKE PLACE AFT MIDNIGHT WITH PCPN CHANCES RAPIDLY DIMINISHING FROM NW TO SE INTO EARLY TONIGHT. SFC HIGH PRES CENTERED ALONG THE CNTRL APPLCHNS WILL NOSE INTO THE AREA LATE TONIGHT AND PROVIDE DRY WX INTO THE FIRST PART OF DAY 2/WED. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY/... FAIRLY PROGRESSIVE/LOW-AMPLITUDE SHORTWAVE WILL MOVE THROUGH THE GREAT LAKES AND OH VLY ON DAY 2. THE DETERMINISTIC MODEL AND ENSEMBLE DATA SHOW A SEASONABLY STRONG/CONVECTIVELY INDUCED LOW /DEEPENING TO SUB 1000MB IN THE OPRNL RUNS/ TRACKING EWD ALONG THE OH RIVER TO THE WV/MD PANHANDLE BY 06Z THU BEFORE REACHING THE DELMARVA/NJ COAST BY 12Z THU. THE 00/06Z NAM AND 21/03Z SREF MEAN ARE SLOW WITH THE SFC WAVE COMPARED TO CONSENSUS. THE 00Z GFS/ECMWF ARE FASTER...AND GIVEN THE QUASI ZONAL FLOW IN THE MID LVLS...A MORE PROGRESSIVE SOLUTION WOULD APPEAR MORE CORRECT. THE DIFFICULT ASPECT OF THE FCST IS IN THE DOWNSTREAM EVOLUTION OF HEAVY RAIN/MCS TSTM COMPLEX THAT IS PROGGED TO APPROACH THE AREA LATE WED NGT. GIVEN RECENT MODEL BIASES WITH THE RAINFALL AXIS TOO FAR NORTH...MADE SOME MANUAL/SWD ADJUSTMENTS TO HIGHEST POPS/QPF WITH THIS SYSTEM. ALSO ADDED +RA WORDING INTO ZONE TEXT AND MAY INCLUDE IN HWO. SHOWERS COULD LINGER INTO THU AFTN AS THE UPPER TROUGH SLIDES THROUGH...BUT POPS WILL BE TRENDING LOWER AS DRIER AIR STARTS TO ARRIVE FROM THE NW. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... MEDIUM RANGE DATA SHOWS HIGH PRES PROVIDING MAINLY DRY WX INTO THE FIRST PART OF THE WEEKEND. AN ISOLD TERRAIN-INDUCED SHWR/TSTM IS POSS SAT AFTN/EVE. INCREASING LLVL MSTR/HUMIDITY ASSOCD WITH APPROACHING FRONTAL SYSTEM WILL SUPPORT AN INCREASE IN POPS FROM SUNDAY INTO MONDAY. && .AVIATION /16Z TUESDAY THROUGH SATURDAY/... LINE OF VERY LIGHT SHOWERS AND VERY BRIEF REDUCTIONS IS NEARING IPT AND MDT/LNS. CONVECTION STARTING UP IN THE WARMER AIR AND BROKEN/SCT CLOUDS IN WRN PA AND ERN OH WILL SLIDE IN BUT NOT GET TO 100PCT COVERAGE. MAY ADD IN MENTION OF VCTS TO BFD FOR THE AFTN. CONVECTION MAY GET ENHANCED IN THE SE AS THIS FIRST LINE OF SHOWERS REACHES THOSE TERMINALS SHORTLY. IFR CIGS AND VSBYS ARE POSSIBLE IN THE HEAVIEST SHOWERS. A COLD FRONT ASSOCIATED WITH THIS SYSTEM WILL PUSH ACROSS THE AREA THIS EVENING. SKIES WILL CLEAR IN THE WAKE OF THE COLD FRONT...WHICH WILL PROBABLY LEAD TO PATCHY FOG AND/OR MVFR/IFR CIGS AND VSBYS POSSIBLE TOMORROW MORNING...ESPECIALLY AT JST AND BFD. AFTER A BRIEF BREAK OF FAIR CONDITIONS ON WEDNESDAY...A POTENT SYSTEM WILL ROLL THROUGH WED NIGHT. VFR/DRY WEATHER THEN RULES FROM THURS AFTN INTO SUNDAY. OUTLOOK... WED NIGHT-EARLY THURS...TS/SHRA WITH REDUCED CIGS/VIS POSS. THU-SAT...NO SIG WX EXPECTED. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...STEINBUGL NEAR TERM...DANGELO/STEINBUGL SHORT TERM...STEINBUGL LONG TERM...STEINBUGL AVIATION...DANGELO/CERU
