The episode as NWS CTP wrote it up.
A warm and very humid airmass led to afternoon and evening showers and thunderstorms across central Pennsylvania. A line north-south of storms formed over the Susquehanna Valley during the afternoon. Some of this activity was exhibiting rotation...prompting a tornado warning near Williamsport that went unverified. Later in the evening, another rounds of storms pushed in from western Pennsylvania.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS State College, PA wrote its last area forecast discussion before the first event at Jun 14, 2:32 PM EST, 2 hours 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 332 PM EDT SUN JUN 14 2015 .SYNOPSIS... A SUBTROPICAL RIDGE WILL REMAIN PARKED JUST OFF THE SOUTHEAST COAST THIS WEEK. PENNSYLVANIA WILL REMAIN IN THE NORTHERN PERIPHERY OF THIS UPPER RIDGE WITH A SURFACE FRONT OSCILLATING OVER THE STATE...PRODUCING PERIODS OF SHOWERS AND GUSTY THUNDERSTORMS WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL. DRIER CONDITIONS WILL ARRIVE FOR WED...BUT ADDITIONAL SHOWERY CONDITIONS ARE EXPECTED AGAIN BY THU. SHOWERS AND STORMS WILL PREVAIL AGAIN FOR MUCH OF THE REMAINDER OF THE WEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... NUMEROUS SHRA/TSRA WITH EMBEDDED HEAVY DOWNPOURS TRAVERSING WESTERN HALF OF PA AT THIS HOUR. CONVERGENCE IN MARGINAL SPEED SHEAR ON THE EASTERN PERIPHERY OF 35 KT 850 MB JET NOSING INTO NORTHEAST OHIO APPEARS TO BE THE TRIGGER FOR MOST OF THIS ACTIVITY, WHICH HAS SHOWN LITTLE ORGANIZATION OTHER THAN PRODUCING SOME RAIN CORES WHICH ARE MOVING ALONG NICELY THUS FAR. DCAPES ON THE ORDER OF 200 TO 400 J/KG NOT SUPPORTIVE OF STRONG COLD POOL GENERATION FOR STRONG WIND GUSTS. HIGHEST DCAPES IN MY CWA THROUGHT TONIGHT ARE OVER MY EXTREME EASTERN COUNTIES WITH HRRR SHOWNING A LITTLE OVER 500 J/KG THIS EVENING. FOCUSING ON THE POTENTIAL FOR HEAVY RAINFALL AND POSSIBLE TRAINING FROM EASTERN OHIO INTO NORTHWEST PA AS THE GREATEST CONCERN...BUT WITH MODERATE CAPES ANY TALLER STORM CAN PRODUCE STRONG GUSTY WINDS. WILL BE RAISING A FLASH FLOOD WATCH FOR MY NORTHWEST MOUNTAINS SHORTLY...IN COLLABORATION WITH CLE AND BUF. FIRST ROUND OF CONVECTION GOING THROUGH NOW WITH LOCALLY 1 INCH PLUS AMOUNTS THIS AFTERNOON. LATE EVENING AND OVERNIGHT ACTIVITY IS MORE LIKELY TO TRAIN...WITH ADDITIONAL 1-2"+ AMOUNTS LIKELY ACROSS WARREN ELK AND MCKEAN COUNTIES AS PW POOL TO OVER 2" THERE. AREA REMAINS IN SLIGHT RISK OF SVR THROUGH TONIGHT. ACTIVITY WILL CONTINUE TO GRADUALLY INCREASE OVER CENTRAL PA FROM WEST TO EAST FROM MID TO LATE AFTERNOON. CAP WILL TAKE A WHILE TO BREAK OVER THE EAST. STRONG TO SEVERE PULSE STORMS WILL BE POSSIBLE AS MODERATE CAPES ARE HARNESSED...ALTHOUGH COMPARED TO PREVIOUS EVENTS DCAPES ARE SOMEWHAT LACKING AS PREVIOUSLY MENTIONED. HEAVY RAIN THREAT OVR THE W AND NW MAY BE EVEN GREATER THAN THE SVR THREAT...WITH 2 TO 3 INCH PLUS LOCAL AMOUNTS POSSIBLE THROUGH LATE TONIGHT. MDL 8H TEMPS ARE SUPPORTIVE OF MAX TEMPS FROM THE U70S OVR THE ALLEGHENY PLATEAU...TO THE M80S ACROSS THE LOWER SUSQ VALLEY. H5 RIDGE AXIS MOVES FROM ALLEGHENY PLATEAU AT 18Z TO THE POCONO PLATEAU BY 00Z...AS A PAIR OF VIGOROUS SHORTWAVES MOVE THROUGH THE EASTERN GREAT LAKES AND THE LOWER OHIO VALLEY. AFOREMENTIONED 850 MB 35KT JET NOSES INTO THE FINGERLAKES REGION BEFORE PROPOGATING SSW ACROSS WESTERN AND CENTRAL PA BY 06Z. WIDESPREAD 1 TO LOCALLY 3 INCH EVENT AMOUNTS ARE LIKELY ACROSS THE NORTHWEST QUARTER TO THIRD OF MY CWA...WITH 1-2" PLUS AMOUNTS EXTENDING ACROSS THE LAUREL HIGHLANDS TO THE CENTRAL AND NORTH CENTRAL MOUNTAINS. FLASH FLOODING WILL BE THE PRIMARY THREAT BEYOND ANY STRONG WINDS PRODUCED BY COLLAPSING CELLS THIS EVENING. BEFORE ITS ALL SAID AND DONE THE LOWER SUSQ SHOULD GET IN ON LOCALLY HEAVY RAINFALL ESPECIALLY AFTER MIDNIGHT AS THE 850 MB SPEED MAX SAGS SOUTHEASTWARD AND PW'S SURGE OVER 2". A BUSY EVENING AND OVERNIGHT AHEAD. && .SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/... CENTRAL PA WILL REMAIN ON NORTHERN PERIPHERY OF SUBTROPICAL RIDGE MONDAY. AXIS OF HIGHEST GEFS PWAT ANOMALIES INDICATE SOUTHERN PA WILL BE THE FOCUS FOR RING OF FIRE CONVECTION. HAVE KEPT POPS ~60-65 PCT ACROSS THE SOUTHERN COUNTIES...WHERE PM TSRA ARE LIKELY. AIR MASS WILL BE WARM AND UNSTABLE AGAIN...BUT MARGINALLY FAVORABLE FOR SVR WX WITH MID LVL WESTERLY FLOW OF ARND 30KTS. MODERATE CAPES WILL BE CREATED BY AFTN BRINGING SLIGHT RISK OF SVR STORMS FROM SPC. BREAKS OF SUN SHOULD HELP PUSH TEMPS WELL INTO THE 80S. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... DID NOT CHANGE A LOT. MAIN THING WAS TO EDGE TEMPS UP A FEW DEGREES HERE AND THERE. TENDENCY FOR EC TO SHOW LESS HEIGHT FALLS EACH DAY. SOME POTENTIAL FOR HEAVY RAIN AGAIN LATE MONNDAY...AS FRONT TILTS BACK TO THE NW FROM LOW DROPPING SE ACROSS NE PA LATE MONDAY INTO EARLY TUE. SOME MORE POTENTIAL FOR HEAVY RAIN AND SEVERE STORMS ON TUE...AS FRONT MOVES SE. HARD TO FOLLOW GFS POPS FOR MDT LATE TUE. FRONT MOVING INTO THAT AREA JUST AFTER PEAK HEATING. THUS WENT HIGHER ON POPS THAN GUIDANCE ACROSS THE SE. STILL ENOUGH PUSH TO GET SOME DRY WEATHER INTO THE AREA LATER TUE NIGHT INTO AT LEAST THE FIRST HALF OF WED. NAM SHOWS A CRAZY DAY ON THU...WITH WARM ADVECTION...SHEAR AND CAPE. THUS WENT RATHER HIGH WITH POPS. AGAIN...AS NOTED ABOVE...DID UP TEMPS SOME. SOME BREAK POSSIBLE LATER FRIDAY INTO SUN...AS MODELS HINT THAT FRONT COULD DROPS SOUTH OF PA. EC NOT SHOWING A LOT OF HEIGHT FALLS...SO HAVE LOW CHC POPS IN FOR SOME OF THE TIME. REALLY NOT SEEING MUCH CHANGE IN THE PATTERN ANYTIME SOON. VERY FAST WEST TO EAST FLOW WILL KEEP ACTIVE WEATHER ACROSS A LARGE CHUCK OF THE COUNTRY THROUGH DAY 10. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... HIGH PRESSURE OFF THE SOUTHEAST U.S. COAST WILL KEEP WARM MOIST AIR IN PLACE. A STATIONARY FRONT STRETCHING GENERALLY WEST TO EAST ACROSS THE STATE WILL CONTINUE TO ACT AS A FOCAL POINT FOR DEVELOPING SHOWERS AND THUNDERSTORMS FOR SEVERAL MORE DAYS. MVFR AND IFR RESTRICTIONS WILL ACCOMPANY SHRA/TSRA FROM WEST TO EAST THROUGH LATE TONIGHT. HEAVY RAIN WILL BE THE PRIMARY THREAT..ALTHOUGH LOCALIZED SFC WIND GUSTS TO 35 KTS POSSIBLE. MVFR AND LCL IFR RESTRICTIONS SHIFT ESE OVERNIGHT. OUTLOOK... MON-TUE...CIG REDUCTIONS NW HALF. PM TSRA IMPACTS. WED...CIG REDUCTIONS POSS SW. OTHERWISE NO SIG WX. THU-FRI...CHC OF SHOWERS AND THUNDERSTORMS. && .CTP WATCHES/WARNINGS/ADVISORIES...
