The episode as NWS CTP wrote it up.
A quasi-stationary frontal boundary was draped from west to east just north of Pennsylvania the morning of June 12th, 2015. This boundary began slipping southward as a cold front during the afternoon...ahead of which scattered strong to severe t-storms developed. Resultant damage was due almost entirely to strong winds...with little in the way of hail reported.
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 12, 2:17 PM EST, 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 317 PM EDT FRI JUN 12 2015 .SYNOPSIS... A SUBTROPICAL RIDGE WILL REMAIN PARKED JUST OFF THE SOUTHEAST COAST THROUGH THE NEXT WEEK. PENNSYLVANIA WILL REMAIN THE NORTHERN PERIPHERY OF THIS UPPER RIDGE WITH A SURFACE FRONT OSCILLATING OVER THE STATE. THIS WEATHER PATTERN WILL BRING WITH IT A CHANCE OF MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS MOST DAYS DURING THE UPCOMING WEEKEND AND NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... NEAR TERM HIGH RES MDL DATA AND SFC OBS AT 16Z INDICATES A WARM FRONTAL BNDRY /SNAKING ITS WAY FROM SWRN NEW YORK TO THE LOWER SUSQ VALLEY/. THIS FRONT WILL LIFT A LITTLE FURTHER NORTH THIS AFTERNOON...BUT MAY HANG UP ACROSS PORTIONS OF THE MIDDLE SUSQ VALLEY AND ADJACENT NE PENN. DESPITE WEAK LG SCALE FORCING...HEATING OF MOIST/UNSTABLE AIR MASS IS LIKELY TO RESULT IN SCT CONVECTION BY AFTN...FOCUSED OVR THE ELEVATED HEATING SURFACES OF THE CENTRAL MTNS...AND NEAR THE AFOREMENTIONED WARM FRONTAL BOUNDARY. ALTHOUGH SHEAR AND CAPE PROFILES NOT PARTICULARLY IMPRESSIVE IN THE VERY NEAR TERM...PROGGED DCAPE VALUES IMPLY THE THREAT OF ISOLD DAMAGING WIND GUSTS. DEEP LAYER SHEAR DOES BEGIN TO INCREASE /BY ABOUT 10KTS OR SO/ LATE IN THE DAY AND THIS EVENING...SO STORMS THAT DO DEVELOP MAY STAND THE BEST CHANCE OF BECOMING SEVERE AROUND OR SHORTLY AFTER DUSK. A FEW POCKETS OF ENERGY HELICITY INDEX AOA 1M2/S2...INCREASE BETWEEN 00-03Z SAT TO A FAIRLY EXTENSIVE BAND OF 1.5-2 M2/S2 FROM THE NCENT MTNS...TO JUST WEST OF THE SUSQ MAINSTEM AT 00Z SAT...THEN CONSOLIDATED ACROSS THE MID SUSQ VALLEY AROUND 03Z. MDL 8H TEMPS OF ARND 18C SHOULD SUPPORT MAX TEMPS FROM THE M80S OVR THE HIGHEST TERRAIN OF THE ALLEGHENIES...TO THE L90S IN THE SUSQ VALLEY. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... A MORE ORGANIZED...AND POTENTIALLY SVR...TSRA THREAT DEVELOPS THIS EVENING ACROSS THE NW MTNS...AS SHORTWAVE APPROACHES FROM THE GRT LKS...PUSHING A COLD FRONT TOWARD THE AREA. MODERATELY STRONG MID LVL FLOW AND ASSOC SHEAR SHOULD SUPPORT AN ORGANIZED LINE OF STRONG TSRA WORKING INTO THE NW MTNS THIS EVENING ALONG AXIS OF LL JET AND PLUME OF ANOMALOUS PWATS/INSTABILITY. THE SVR THREAT SHOULD DIMINISH LATE TONIGHT...AS BEST LG SCALE FORCING PASSES NORTH OF THE STATE AND BLYR COOLS/STABILIZES. POPS BASED ON LATEST SREF/GEFS OUTPUT RANGE FROM CATEGORICAL ACROSS THE NW MTNS...TO CHC ACROSS THE LOWER SUSQ VALLEY. DYING SFC COLD FRONT WILL SAG SOUTH ACROSS CENTRAL PA SATURDAY...BRINGING A CHC OF LINGERING SHRA/TSRA...ESP ACROSS THE SOUTHERN COUNTIES. CONSALL OUTPUT SUPPORTS MAX TEMPS FROM THE M70S NW MTNS TO M80S SE. && .LONG TERM /SUNDAY THROUGH FRIDAY/... LITTLE CHANGE TO THE EXTENDED FORECAST TODAY AS THE PROVERBIAL RING OF FIRE ON THE PERIPHERY OF THE LARGE SOUTHEAST CONUS UPPER DIGE WILL BE SITUATED ACROSS CENTRAL PA FROM MUCH OF THE UPCOMING WEEKEND THROUGH MID WEEK. A WEAK FRONTAL SYSTEM MAY PROVIDE SOME DRYING AND BY LATE IN THE WEEK...BUT WITH ONLY A 1020MB SFC HIGH PROGGED TO CROSS THE NORTHERN GLAKS REGION...PERSISTENCE FORECAST IS LIKELY THE BEST ONE WITH ABOVE CLIMATOLOGICAL POPS INDICATED THROUGH THE END OF THE COMING WEEK. AT OR ABOVE AVERAGE NORMAL MAX TEMPS ARE EXPECTED IN THIS PATTERN...AS WELL AS ABOVE NORMAL MIN TEMPS BASED ON WELL ABOVE NORMAL PW. SENSIBLE WEATHER WILL BE QUITE SUMMERLIKE...WITH VERY WARM AND HUMID CONDITIONS AND DAILY CHANCES OF MAINLY DIURNAL CONVECTION. BEST CHC FOR MORE WIDESPREAD CONVECTION WILL BE TUESDAY AFTERNOON AND THURSDAY AFTERNOON WITH STRONG 5H TROFS FLATTENING AND ULTIMATELY DISPLACING THE SPRAWLING SOUTHEAST UNITED STATES UPPER RIDGE OFFSHORE BY LATE IN THE WEEK. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... A WEAK WARM FRONTAL BOUNDARY STRETCHED FROM NEAR KBFD...TO KUNV AND KMDT/KLNS AT 14Z...WILL LIFT NORTH INTO NEW YORK STATE TODAY. AREAS OF 5-6SM VSBYS IN HAZE WILL PERSIST ACROSS MAINLY THE LOWER SUSQ VALLEY THIS AFTERNOON. OTHERWISE...EXPECT VFR CONDITIONS TO PREVAIL IN MOST LOCATIONS FOR MAJORITY OF THE TIME THROUGH THE LATE AFTERNOON HOURS. ISOLATED/SCATTERED TSTMS WILL DEVELOP IN MID/LATE AFTERNOON OVER THE WEST...WHICH WILL BRING MAINLY LOCAL RESTRICTIONS. MENTIONED VCTS FOR A SHORT WINDOW IN THE TAFS. BETTER PROB FOR TSTM IMPACTS LOOKS TO BE THIS EVENING AS A SCT/BKN LINE OF STORMS SLIDES THROUGH AHEAD OF APPROACHING COLD FRONT...STARTING AROUND 00Z IN THE NW.
