The episode as NWS CTP wrote it up.
Severe thunderstorms crossed the Commonwealth during the mid afternoon and early evening hours, producing multiple reports of straight line damaging winds. The primary damage area started in Clearfield County along Interstate 80 and extended east-southeast through the south central mountains and into the lower Susquehanna Valley. Thunderstorm structures organized into bowing line segments, which tapped and accentuated anomalously strong environmental winds in the middle to lower atmosphere. Numerous measured peak wind gusts between 50 and 80 mph were reported via ASOS. One injury occurred in Cumberland County (Monroe Township) when a tree fell onto a vehicle.
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 Apr 16, 1:50 PM EST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 250 PM EDT FRI APR 16 2010 .SYNOPSIS... A STRONG COLD FRONT WILL CROSS THE ENTIRE REGION THIS EVENING...TOUCHING OFF NUMEROUS THUNDERSTORMS. SOME OF THESE STORMS COULD PRODUCE DAMAGING WINDS AND SMALL HAIL. MUCH COOLER WEATHER WILL FOLLOW BEHIND THE FRONT FOR THE WEEKEND. SCATTERED MOUNTAIN RAIN AND SNOW SHOWERS WILL OCCUR AS COLD AIR CROSSES THE GREAT LAKES. GRADUALLY MODERATING TEMPERATURES AND GENERALLY DRY WEATHER IS EXPECTED FOR THE MONDAY THROUGH THURSDAY PERIOD. && .NEAR TERM /UNTIL 11 PM THIS EVENING/... POP UP STORMS NOW PREVALENT ACROSS THE ENTIRE SRN CWA...MOVING E AT 40-50KTS...WITH THE STRONG STEERING LEVEL FLOW. LATEST RUC SHEAR PROFILES ARE STILL UNIDIR WITH 50+KT FM 8H-7H. FIRST PUSH OF STORMS SEEMS TO BE ALONG AND JUST BEHIND A WEAK S/WV. A SECOND AREA OF SVR STORMS IS DEVELOPING IN THE WRN PART OF SVR WW71 ASSOCD WITH THE BEST PUSH OF DEWPOINTS AND 45-50KT LLJET. SHORT- RANGE MDLS KEEP CAPES IN THE SUB-1000 RANGE...MAINLY DUE TO THE LACK OF AVBL MSTR. DEWPOINTS IN THE U40S AND L50S NOW WILL NOT RISE TOO MUCH INTO THE EVENING. THE SOUNDINGS ARE ALMOST WESTERN- LIKE WITH VERY PRONOUNCED DRY MIXED LYR UNDER THE CLD BASES - RUNNING ABOVE 5KFT FOR THE MOST PART. THIS COULD EASILY ALLOW THE WINDS AT THAT LVL TO MIX DOWN. SPC WW71 RUNS THRU 00Z/8PM LOCAL. OPTED TO INCL MOST OF THE AREA IN COORD WITH SPC TO ALLOW FOR OH CONVECTION TO SLIDE EAST AND MAYBE EVEN NORTH IN ADVANCE OF THE REAL COLD FRONT/SFC WIND SWITCH. WIND IS THE MAIN THREAT WITH THESE STORMS...AS MID LVL LAPSE RATES NOT TOO STEEP AND TOPS EXPECTED TO BE AOB22KFT. ALSO...M20C LEVEL IS UP AROUND 18KFT. CONVECTION SHOULD WANE AS THE EVENING CONTINUES AND WE LOSE ANY DECENT CAPE. THIS WAS THE INITIAL THOUGHT IN LEAVING FAR SERN PA OUT OF THE WATCH FOR NOW...BUT WE CAN ADD IT IN LATER IF THREAT EXPANDS THAT FAR. NORMAL MODE IS FOR STORMS TO GET A BIT STRONGER AS THEY GET DOWN THE HILLS AND INTO A SOUPIER AIRMASS...AND THEY DO HAVE THE HIGHER DEWPOINTS RIGHT NOW. KMDT AND KLNS ARE IN THE M50S FOR DEWPOINTS. BUT...THEY HAVE SEEN THEIR TEMPS BE SUPPRESSED BY THE LACK OF MIXING THERE SO FAR TODAY. BY THE TIME THEY MIX...THEY MAY BE WETTED/COOLED. && .SHORT TERM /11 PM THIS EVENING THROUGH SATURDAY NIGHT/... AFTER THE END OF THE CONVECTION LATER THIS EVENING/EARLY TONIGHT...THE COLD AIR WILL BE THE STORY. IT WILL FEEL PRETTY RAW. THE 8H TEMPS DIP WELL NEGATIVE AND TROF OFF TO THE NE WILL FORCE LOTS OF COLD AIR ACRS THE LAKES AND INTO THE HIGHER TERR OF WRN PA. THIS WILL MAKE NUMEROUS RASH...AND THE HIGHER ELEVS - AND PERHAPS INTO THE VALLEYS - WILL SEE WET SNOW MIX IN. HAVE BARELY MENTIONED ACCUMS LATER SAT NIGHT IN THE NW. ELSEWHERE..IT WILL BE TOUGH TO MAKE ACCUMS. SKIES WILL BE REMINISCENT OF OCTOBER/NOV. LOTS OF CLOUDS DOWNSTREAM...BUT PERHAPS SOME SUN IN THE SE WITH DOWNSLOPE ON SATURDAY. MINS TONIGHT IN THE M30S NW TO L50S SE. THE TEMPS SHOULD HOLD OR EVEN DIP SLIGHTLY - ESP IN THE NW ON SAT BEFORE MAKING A TINY UPTICK IN THE AFTN. TEMPS DROP AGAIN SAT NIGHT...HENCE THE THOUGHT OF MINOR ACCUMS ON THE HILL TOPS NW...BUT WINDS REMAIN UP TO MORE THAN 5-6KT FOR THE ENTIRE CWA. CLOUDS ALSO TOUGH TO CLEAR OUT UNDER COLD ADV AND WITH THERMAL TROF STILL TO THE WEST. THEREFORE...LITTLE WORRY SO FAR FOR FROST IN THOSE AREAS IN THE GROWING SEASON ALREADY ON SAT NIGHT. && .LONG TERM /SUNDAY THROUGH THURSDAY/... A FEW RAIN AND EVEN SNOW SHOWERS MAY LINGER INTO SUNDAY. AFTER THIS...MADE THE PERIOD LATE MONDAY INTO WED DRY. TEMPS NEAR TO SLIGHTLY BELOW NORMAL. NEXT FRONT NOW COMES IN ON THU...NOT WED...THUS I PUT SMALL CHC POPS IN FOR THU. WENT WITH DRY WEATHER FOR FRIDAY...WITH A WEAK NORTHERLY FLOW. A LOT OF SPREAD IN THE MODELS WITH LONGER PERIODS. MODELS GOING BACK AND FOURTH BTWN A STRONG NORTHERLY FLOW AND WEAK SW FLOW WITH WARM ADVECTION BY DAY 7. GRIDS LOOK GOOD OVERALL...NO HUGE CHANGES MADE. THANKS TO THE MID SHIFT THAT DID A LOT OF DAY 7. GRIDS ADJUSTED EARLIER...DUE TO THE THREAT OF SEVERE WEATHER. CHECKED THINGS OVER AGAIN AFTER LUNCH...GRIDS STILL IN LINE WITH NEW MODELS AND OTHERS. THAT IS ALL FOR THIS PACKAGE...GOING TO TRY TO ENJOY MY ONE DAY OFF...BEFORE I GET BACK IN THE LONG TERM GRIDS ON SUNDAY. THUS I WILL GET TO SEE HOW GOOD THIS FCST DOES. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... A SEVERE THUNDERSTORM WATCH HAS BEEN PUT OUT IN ANTICIPATION OF SHOWERS AND THUNDERSTORMS WILL THAT WILL OVERSPREAD THE REGION DURING THE AFTERNOON. IT APPEARS THE MAIN THREAT WITH THESE STORMS WILL BE WINDS...NOT SURPRISING AS WINDS AHEAD OF THE APPROACHING COLD FRONT ARE ALREADY GUSTING TO AROUND 30KTS OUT OF THE WEST AT ALL AIRFIELDS WEST OF KUNV. WAS NOT CONFIDENT ENOUGH IN THE EXTENT OF TSRA COVERAGE/INTENSITY THIS AFTERNOON TO INCLUDE A TEMPO DROP TO MVFR/IFR IN TSRA...SIMPLY LEFT A MENTION OF CB. HOWEVER WILL CLOSELY MONITOR THE DEVELOPING SITUATION...AND AMENED AS NECESSARY. OUTLOOK... SAT...MVFR WITH ISO IFR ACROSS THE MTS. SUN...MVFR ACROSS THE MTS...TO VFR. MON-WED...MAINLY VFR. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...DANGELO NEAR TERM...DANGELO SHORT TERM...DANGELO LONG TERM...MARTIN AVIATION...DICKEY
