The radar
The State College radar (KCCX), 146 km from the middle of the area, began a volume at 23:28 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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
Washington/Dulle, VA (KIAD), launched 12:00Z, 11.4 hours before the alert went out and 198 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.

Area forecast discussion, Sep 30, 4:15 PM EDT, 3 hours 9 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
415 PM EDT THU SEP 30 2010
.SYNOPSIS...
A DEEP PLUME OF MOISTURE ASSOCIATED WITH THE REMNANTS OF TROPICAL
STORM NICOLE WILL CONTINUE TO FOCUS INTO CENTRAL AND EASTERN
PENNSYLVANIA AND BRING MODERATE TO HEAVY RAINFALL THROUGH
TONIGHT. EXCESSIVE RAINFALL OVER EASTERN PENNSYLVANIA WILL LIKELY
CAUSE EXTENSIVE FLOODING. THE REMNANT CIRCULATION WILL LIFT NORTH
ALONG THE MID ATLANTIC COAST TONIGHT INTO EARLY FRIDAY...ARRIVING
IN SOUTHERN NEW ENGLAND BY FRIDAY NIGHT. A COOLER AND DRIER AIR
MASS WILL OVERSPREAD THE STATE INTO THE WEEKEND WITH TEMPERATURES
AVERAGING BELOW SEASONAL NORMALS. ANOTHER DEEP TROUGH IS EXPECTED
TO DIG SOUTHWARD INTO THE OHIO AND TENNESSEE VALLEYS BRINGING
UNSETTLED WEATHER TO THE AREA NEXT WEEK.
&&
.NEAR TERM /TONIGHT/...
HEAVY/EXCESSIVE RAINFALL EVENT CONTINUES ACROSS CENTRAL AND ERN
PENNSYLVANIA LATE THIS AFTERNOON. WV/IR SATL IMAGERY SHOWS LONG-
FETCH TROPICAL MOISTURE PLUME STREAMING NWD INTO THE REGION...WITH
ACCOMPANYING PWAT VALUES +2-4SD ABOVE NORMAL. THE LATEST RUC DATA
SHOWS A SFC WAVE LIFTG NWD INTO CNTRL PA...WITH A RELATIVELY
NARROW N-S DEFORMATION PRECIP AXIS SETTING UP OVRHEAD PER LATEST
REGIONAL RDR IMAGERY. RAINS ARE TAPERING OFF ACROSS PORTIONS OF
THE LAUREL HIGHLANDS...WHILE BCMG A BIT MORE SHOWERY IN THE LWR
SUSQ. EXPECT LOCALLY HEAVY RAIN RATES /1-2" PER HOUR/ TO CONTINUE
WITHIN THE DEFORMATION BAND OVR THE CNTRL MTNS. THE MAIN FOCUS
FOR THE FIRST PERIOD IS THE REMNANT CIRC /T.S NICOLE/ FCST TO MOVE
UP ALONG THE MID ATLC COAST TWD THE DELMARVA TONIGHT.
THE SECONDARY THREAT FOR LOW-TOPPED ROTATING STORMS/ISOLD
TORNADOES HAS DIMINISHED SOMEWHAT AS RDR SHOWS A MINIMUM IN
CELLULAR CONVECTIVE ACTIVITY. ENVIRONMENT REMAINS CHARACTERIZED BY
VERY STRONG LOW LEVEL STRONG SHEAR AND WEAK INSTABILITY. REGIONAL
VWP/S TO THE SOUTH ARE SHOWING VERY IMPRESSIVE 60-70 KT SLY LLJ AT
850MB POINTED INTO THE WATCH AREA. TORNADO WATCH 689 CONTINUES
THROUGH 23Z.
THE MAIN MDL DIFFS ARE WITH THE PLACEMENT/TRACK OF THE OF THE SFC
LOW CIRC AS IT LIFTS NWD ALONG WAVERING N-S FNTL ZONE TONIGHT.
THIS HAS SIGNIFICANT IMPLICATIONS FOR ADDITIONAL HEAVY RAINFALL
FOR ERN PA. THE ECMWF...WHICH APPEARS TO HAVE HAD THE BEST HANDLE
ON THE PATTERN THE LAST FEW DAYS...SHOWS A TRACK SLIGHTLY WWD OF
THE CONSENSUS AND BRINGS HEAVY RAINS ACROSS MUCH OF THE FLOOD
WATCH AREA. WITH VIRTUALLY ALL OF THE SAME HIGHLY ANOMALOUS HEAVY
RAIN INGREDIENTS STILL IN PLACE...MY MANUALLY BLENDED QPF THROUGH
12Z FRIDAY SHOWS ANOTHER 1-3" OVER THE LOWER SUSQ VLY/MAIN STEM
BASINS. IN GENERAL...I'M ANTICIPATING ANOTHER RIBBON OF HVY RNFL
OVER MY ERN MOST CNTYS BUT THE LOCATION IS CRUCIAL WITH RESPECT TO
POTENTIAL FLOODING CONDITIONS. THE WRN EDGE OF THE PRECIP SHIELD WILL
BE SHARP...LEADING TO A DIFFICULT FCST. OVERALL STILL EXPECT STORM
TOTALS FOR THIS EVENT OF A SOLID 2-5" IN THE FLOOD WATCH AREA WITH
ISOLD SPOTS OF 8-10" MAINLY OVER THE LWR SUSQ VLY.
&&
.SHORT TERM /FRIDAY/...
AS THE UPPER TROUGH AND ATTENDANT SFC LOW LIFTS N/NE FRI
AFTN...IT WILL ALLOW COOLER AND DRIER AIR TO OVERSPREAD THE
AREA BEHIND A GUSTY NNW WIND. THIS SHOULD EFFECTIVELY BRING AN
END TO THE RAIN IN MOST LOCATIONS...WITH LINGERING LIGHT
DEFORMATION PRECIP ENDING OVER ERN SXNS EARLY IN THE DAY. SFC
RIDGING WILL PROVIDE IMPROVG CONDS FRI NGT.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
ALL GUIDANCE REMAINS IN AGREEMENT IN CARVING OUT A SOLID MEAN
TROUGH OVER THE ERN CONUS WITH ADDITIONAL AMPLIFICATION EXPECTED
THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK...BEHIND A DIGGING
SHORTWAVE TROUGH AND UPPER LVL JET DIVING SEWD FROM THE NRN
PLAINS/UPR MS VLY INTO MS/OH VLY. A CONSENSUS SOLUTION IS
EMERGING AS THE GFS/GEFS ARE CLEARLY TRENDING TWD THE ECMWF/GEM
WHICH BOTH HAVE KEPT GREAT CONTINUITY IN DEVELOPING A SIGNIFICANT
CLOSED LOW IN THE EAST FOR THE LAST SEVERAL RUNS. COOLER AND
MAINLY DRY WEATHER SHOULD GIVE WAY TO UNSETTLED CONDS BY MID-WEEK
AS A COASTAL LOW IS DRAWN NNWWD AND OCCLUDES INVOF THE
DELMARVA/MID-ATLC COAST. TEMPERATURES STILL AVERAGING BELOW
NORMAL THRU THE PD.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
AN AREA OF LOW PRESSURE RIDING UP THE EAST COAST WILL CONTINUE TO
PRODUCE WIDESPREAD MODERATE TO HEAVY RAIN ACROSS ALL OF CENTRAL PA
AND THE SUSQUEHANNA RIVER VALLEY THROUGH EARLY THIS EVENING.
WIDESPREAD IFR CIGS AND VSBYS...WITH AREAS OF LIFR/VLIFR CIGS ACROSS
THE SUSQUEHANNA VALLEY AND WRN MTNS OF PENN WILL PERSIST INTO
TONIGHT.
A WARM FRONT NEAR THE SURFACE HAS PUSHED NORTHWARD TO NEAR
INTERSTATE 81 AT 16Z. THIS BOUNDARY WITH TEMPERATURES WILL PUSH A
BIT FURTHER TO THE NORTH AND WEST THIS AFTERNOON. THIS COULD ALLOW
CIGS TO RISE SIGNIFICANTLY THERE AT TIMES AFTER 18Z. HOWEVER...THIS
UNSTABLE AIR MASS COULD ALSO SPAWN SCT STRONG/ROTATING LOW-TOPPED
TSRA. MOVMT OF TSRA CELLS WILL BE QUICKLY /45KTS/ FROM SOUTH TO
NORTH...AS WINDS OF 40-50 KTS FROM THE SSE ARE PRESENT WITHIN 2 KFT
AGL.
GIVEN THE UNCERTAINTY OF CONVECTION...WILL HANDLE WITH A CB
APPENDAGE AT KMDT FOR NOW. ANOTHER CONCERN WILL BE POTENTIAL OF
LOW LVL WIND SHEAR...AS THE POWERFUL LOW LVL JET LIFTS ACROSS
EASTERN PA TODAY. LLWS CRITERIA MOST LIKELY TO BE MET AT KIPT DUE
TO LOCAL TOPOGRAPHIC EFFECTS. HOWEVER...CAN/T RULE IT OUT
ELSEWHERE.
AS LOW LIFTS NORTH OF THE REGION...WINDS WILL SHIFT TO THE NORTHWEST
AT MOST TAF SITES DURING THE AFTN AND EARLY EVENING. GENERALLY
IMPROVING CONDS EXPECTED TONIGHT...AS LAST OF THE RAIN TAPERS OFF
ACROSS EASTERN PA. HOWEVER...RESIDUAL LOW LVL MOISTURE ASCENDING THE
MTNS WILL LIKELY KEEP LOW /IFR/ CIGS GOING AT KBFD AND KJST.
OUTLOOK...
FRI...IFR TO MVFR...MAINLY IN THE MORNING ACROSS THE NRN AND WRN
MTNS OF PENN. VFR TO MVFR ON THE AFTERNOON WITH A GUSTY NW
WIND.
SAT...NO SIG WX EXPECTED.
SUN...MVFR/SHOWERS POSS KJST.
MON...NO SIG WX EXPECTED.
&&
.HYDROLOGY...
ADDITIONAL RAINFALL THROUGH 12Z FRIDAY OF 2-3" IN THE LOWER MAIN
STEM SUSQ AND ERN TRIBS WILL LIKELY CAUSE MODERATE TO MAJOR
FLOODING ON THE CONESTOGA AND SWATARA RIVERS. MANY OF THE LARGER
RIVERS AND STREAMS IN THE WEST BRANCH AND LOWER MAIN STEM SUSQ ARE
EXPECTED TO SWELL TO NEAR BANKFULL LEVELS AND APPROACH FLOOD
STAGES BY FRIDAY AFTERNOON.
