FORECASTER:What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 7, 4:25 PM EDT, 2 hours 34 minutes earlier.
Area forecast discussion, Jul 7, 4:25 PM EDT, 2 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 425 PM EDT SAT JUL 7 2012 .SYNOPSIS... THE HOTTEST DAY OF THE SUMMER SO FAR WILL GIVE WAY TO RELIEF FROM A COLD FRONT AND THUNDERSTORMS THAT WILL SAG SOUTH ACROSS THE COMMONWEALTH LATE THIS AFTERNOON THROUGH EARLY SUNDAY. THE COOL DOWN THAT FOLLOWS THIS COLD FRONT WILL LAST MUCH OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... INTENSE SQUALL LINE/MCS HAS BEEN PROGRESSING SOUTH FROM THE NRN MTNS OF PENN AND AIMED DIRECTLY AT THE MID SUSQ VALLEY AND SURROUNDING CENTRAL MTNS. HISTORY OF LARGE HAIL /UP TO 1.75 INCHES/ AND WIND DAMAGE ACROSS THE NRN MTNS THE PAST FEW HOURS. THE EASTERN END OF THIS LINE FALLS RIGHT WITHIN A DISTINCT BULLSEYE OF TORNADO THREAT BASED ON LLVL SHEAR/HELICITY AND EHI. HOWEVER...LOCAL STUDIES ON AN EXTENSIVE TORNADO DATABASE OVER THE PAST DECADE OR SO SUGGESTS THAT LCLS AND SFC BASED T/TD SPREADS REMAIN TOO HIGH FOR MORE THAN A BRIEF EF0 TORNADO INVOF KIPT AND POINTS EAST AND SE LATE TODAY. MESO ENVIRONMENT JUST EAST OF KIPT THROUGH SULLIVAN AND NRN COLUMBIA COUNTIES MAY HAVE BEEN MODIFIED BY LATE MORNING TSRA AND OUTFLOW BOUNDARIES TO FAVOR RELATIVELY LOWER LCL HEIGHTS. THE PRIMARY SEVERE WEATHER THREAT IS LARGE HAIL UP TO 2 INCHES IN DIAMETER AND DOWNBURST GUSTS FROM THE NORTHWEST...UP TO 75 MPH. TSRA WILL PROGRESS SEWRD THROUGH SCHUYLKILL COUNTY THROUGH EARLY THIS EVENING WITH THE SOUTHERN AND WRN END OF THE LINE BECOMING MORE SCTD/BROKEN AS IT ENCOUNTERS MUCH WARMER MID LEVEL AIR...AND IS MORE DETACHED FROM THE STRONGER LOW-MID LEVEL WNW SHEAR. OTHERWISE...ABUNDANT SUNSHINE WILL CONTINUE FOR A FEW...TO SVRL MORE HOURS ACROSS SOUTHERN PENN. NEAR RECORD HIGH TEMPS WILL OCCUR ACROSS THE LOWER SUSQ...AND CONTINUE TO PRODUCE DANGEROUSLY HIGH HEAT INDICES OF AROUND 105F. THE REAL PUSH OF COOLER AND DRIER AIR WAITS UNTIL LATE TONIGHT OR EARLY SUNDAY TO GET INTO FAR NORTHERN PORTIONS OF THE CWA...AND TAKES UNTIL SUNDAY NIGHT TO REACH THE SOUTHERN BORDER. WILL KEEP MINS VERY MILD IN THE SRN HALF OF THE AREA. THE NRN TIER COUNTIES WILL DIP INTO THE L-M60S...WHICH ARE NOT FAR FROM NORMALS. THE SOUTHERN TWO THIRDS OF PA WILL REMAIN MUGGY WITH AREAS OF CLOUDS AND ANOMALOUSLY HIGH PWATS KEEPING OVERNIGHT LOWS IN THE UPPER 60S TO MID 70S. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... THE FRONT WILL SLOW AS IT MOVES SOUTH AND AWAY FROM THE STRONGER WNW FLOW ALOFT...AND HIGH PWAT AIR OF NEARLY 2 INCHES WILL KEEP SCT SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGH EARLY SUNDAY EVENING IN THE SOUTH. A SLIGHT RISK FOR SVR TSRA REMAINS IN PLACE OVER THE SRN TIER OF PENN FOR SUNDAY. FAIRLY DEEP LIFT ALONG THE FRONT WILL COMBINE WITH ANOMALOUSLY HIGH MOISTURE AND HEAT...LEADING TO SIGNIFICANT CAPE AND MODERATE SHEAR AGAIN SUNDAY. CLOUDS AND THE COOLER AIR ON AVERAGE /ESPECIALLY ACROSS THE CENTRAL AND NORTH/ WILL CHOP A GOOD 10 TO 15F OFF SUNDAY HIGHS VS SATURDAY. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... A WELCOME RETURN TO NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES AND LOWER HUMIDITY IS IN STORE FOR EARLY NEXT WEEK...AS THE UPPER LEVEL RIDGE RETROGRADES TO THE SW UNITED STATES AND A TROF DIGS INTO THE NORTHEAST. A FRONTAL BOUNDARY REMAINS ENTRENCHED ALONG OUR SOUTHERN BORDER THROUGH THE FIRST HALF OF THIS WEEK. THIS WILL ALLOW CENTRAL PA TO BE THOROUGHLY ENTRENCHED IN THE DRY AIR...AND ACCORDINGLY HAVE ONLY LEFT CHANCE POPS ALONG THE MASON DIXON. 12Z GEFS HAS THE STALLED LONG WAVE TROUGH OVER US THROUGH THE MIDDLE OF THE WEEK...WITH FINALLY LIFTING BY THURSDAY AND THE STRONG JET PUTS CENTRAL PA IN THE JET EXIT REGION. HOWEVER...LACK OF MOISTURE AND SUBSTANTIAL HEATING SHOULD LIMIT ANY CONVECTION. AS SUCH HAVE LEFT ONLY CHANCE POPS THURSDAY THROUGH FRIDAY. WARMER AIR SHOULD ADVECT IN NEXT WEEKEND AS A RIDGE BUILDS OVER THE REGION...HOWEVER MAX TEMPERATURES SHOULD REMAIN RIGHT AROUND NORMAL. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... COLD FRONT DROPPING SOUTH INTO PA WILL SUPPORT A SIGNIFICANT...NEARLY EAST/WEST LINE OF STRONG TO SVR TSRA WITH A 15-30 MINUTE PERIOD OF IFR CONDITIONS /BRIEFLY LIFR/. THE POOREST FLYING CONDS WILL BE NEAR AND TO THE EAST OF A LINE FROM KIPT TO KMDT AND KLNS THROUGH 01Z SUNDAY.
