NWS State College, PA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 28, 2:52 PM EDT, 20 minutes earlier.
Area forecast discussion, Jun 28, 2:52 PM EDT, 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 252 PM EDT FRI JUN 28 2013 .SYNOPSIS... AN UNSEASONABLY INTENSE UPPER TROUGH WILL CARVE OUT OVER THE EASTERN UNITED STATES FROM THE GREAT LAKES TO THE NORTHEASTERN US THROUGH THE WEEKEND INTO EARLY NEXT WEEK. THIS WILL BRING AN EXTENDED PERIOD OF UNSETTLED WEATHER TO THE REGION WHICH COULD LAST INTO THE FIRST DAYS OF JULY. && .NEAR TERM /UNTIL 11 PM THIS EVENING/... UPDATED THE NEAR TERM TO INCLUDE THE EXPANDED SEVERE THUNDERSTORM WATCH... SVR WATCH #386 IN EFFECT FOR SOUTHWEST QUARTER OF CENTRAL PA THROUGH 800 PM THIS EVENING. ENHANCED SHEAR AND CONVERGENCE IN THIS AREA WITH FAVORABLE INSTABILITY SHOULD PROMOTE MORE ORGANIZED STORMS AND THE POTENTIAL FOR BOWING LINE SEGMENTS AND POTENTIAL WIND DAMAGE AND LARGE HAIL. PULSE STORMS ACROSS THE NORTHWEST HAVE PRODUCED MARGINAL HAIL AND ONE SEVERE REPORT...WILL CONTINUE TO MONITOR AS WELL. SEVERAL TRIGGERS ROTATING THROUGH THE BROAD UPPER TROF EARLY THIS AFTERNOON. BEST FORCING IS NOW SPREADING SOUTHEASTWARD FROM ONTARIO TOUCHING OFF A CLUSTER OF SHOWERS AND THUNDERSTORMS WITH BRIEF HEAVY RAINFALL. WILL WATCH THESE FOR PULSE HAIL AND LOCAL STREET FLOODING AND PONDING OF WATER IN POOR DRAINAGE AREAS...AND HOPE THEY REMAIN NORTH OF YDY/S RAINFALL MAX OVER NORTHWEST CLEARFIELD COUNTY. WEAK RIDGING AT THE SURFACE AND ALOFT WILL CONTINUE TO ALLOW FOR SOME BREAKS IN THE LAYERED STRATO AND ALTOCU CLOUDS THIS AFTERNOON. DESTABILIZATION IN THE MODERATELY UNSTABLE ENVIRONMENT WILL SUPPORT LOCALLY HEAVY DOWNPOURS AND WIND GUSTS TO 35 MPH AND SOME HAIL. IN THE MORE HIGHLY SHEARED ENVIRONMENT OVER THE LAUREL HIGHLANDS INTO THE SOUTH CENTRAL MOUNTAINS...SOME BOWING LINE SEGMENTS ARE POSSIBLE. LATEST 4KM SPC WRF SHOWS THIS EVOLUTION WITH RAPID STORM MOTIONS INTO THE SOUTH CENTRAL MOUNTAINS MID TO LATE AFTERNOON. ANOTHER ACTIVE AFTERNOON FOR SURE. STILL...THIS IS AN IMPROVEMENT OVER THU WITH LESS OF A HEAVY RAINFALL THREAT. HIGH CHANCE TO LIKELY POPS FOCUSED ALONG THE SOUTHERN TIER THROUGH THIS EVENING. EXPECT ACTIVITY TO QUICKLY DWINDLE BY LATE EVENING WITH A QUIET OVERNIGHT AND LIKELY EARLY MORNING FOG FORMATION. && .SHORT TERM /11 PM THIS EVENING THROUGH 6 PM SATURDAY/... PRECIP WATER VALUES WILL DIP BY AROUND 0.50 INCH TONIGHT...AND PERIODS OF CLEARING WILL ALLOW TEMPS TO COOL OFF NICELY...ESPECIALLY ACROSS CENTRAL AND NWRN PENN WHERE LOWS EARLY SAT WILL VARY FROM THE MID 50S TO AROUND 60F. LINGERING...SLIGHTLY HIGHER PWATS ACRS THE LOWER SUSQ VALLEY WILL KEEP TEMPS FROM FALLING BELOW THE MID 60S. DAYTIME HIGHS CONTINUE TO TREND DOWNWARD INTO THE WEEKEND WITH HIGH TEMPS A FEW...TO SEVERAL DEG BELOW NORMAL ACROSS THE CENTRAL AND NW MTNS GIVEN CLOUDIER SKIES AND AFTERNOON PRECIPITATION. THE UNSEASONABLY LOW HEIGHTS WILL COVER THE OHIO VALLEY AND WESTERN PA ON SATURDAY...A PATTERN FAVORABLE FOR DIURNAL CONVECTION GIVEN COOL TEMPS ALOFT/STEEP LAPSE RTS. WILL MAINTAIN LIKELY POPS FOR PM SHRA/TSRA ACROSS THE WESTERN COUNTIES BASED ON LATEST 00Z/03Z GEFS AND SREF GUIDANCE. ENS MEAN 925MB TEMPS INDICATE SAT WILL BE ANOTHER WARM DAY ACROSS THE EASTERN HALF OF THE STATE...WHILE CLOUDS/PRECIP KEEP READINGS COOLER ACROSS THE WEST. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... THE SLOW MOVING UPPER TROUGH THAT IS EXPECTED TO DEVELOP AND LINGER OVER THE EASTERN US IS FORCING ONE OF THOSE RARE FORECASTS FROM THE DEPARTMENT OF REDUNDANCY DEPARTMENT. DAILY MENTION OF SHOWERS AND STORMS WILL SOUND TEDIOUS AND REPETITIVE IN THE FORECAST...BUT THERE ISN'T A PERIOD THROUGH THE WHOLE OF NEXT WEEK WHEN THERE SEEMS LIKE THE REGION WILL NOT SEE AT LEAST SCATTERED SHOWERS OR STORMS. TEMPERATURES WILL AVERAGE NEAR TO SLIGHTLY BELOW NORMAL GIVEN THE EXPECTED LOWER THAN NORMAL UPPER HEIGHTS...CLOUD COVER AND EXPECTED PRECIPITATION CHANCES. THE ANOMALOUS UPPER TROUGH IS EXPECTED TO SLOWLY RETROGRADE NEXT WEEK...WITH HINTS THAT THE THE BERMUDA RIDGE WILL EXPERIENCE A RESURGENCE INTO THE EASTERN US TOWARD NEXT WEEKEND...HINTING AT A WARMER BUT STILL STILL HUMID AIRMASS TO RETURN TO THE REGION. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... SCT SHOWERS AND TSTMS INCREASE IN COVERAGE THRU LATE AFTN...WITH SOME STG-SVR STORMS POSSIBLE ESPECIALLY OVER THE SWRN-SCNTRL AIRFIELDS. THE CONVECTION SHOULD BE DIURNALLY DRIVEN AND WEAKEN/DISSIPATE WITH THE LOSS OF HEATING. SOME FOG/STRATUS MAY DEVELOP OVERNIGHT GIVEN LGT WINDS AND HIGH SFC DEWPOINTS/RESIDUAL BLYR MSTR. A LARGE UPPER LEVEL TROUGH WILL CARVE OUT OVER THE EASTERN U.S. INTO THE WEEKEND...BEFORE MIGRATING SLOWLY WESTWARD INTO THE MIDWEST AND PLAINS DURING THE FIRST WEEK OF JULY. THIS WILL RESULT IN A PROLONGED PERIOD OF UNSETTLED CONDITIONS WITH DAILY CHANCES FOR SCT SHOWERS AND THUNDERSTORMS. SOME FOG MAY ALSO BE POSSIBLE A FEW HOURS EITHER SIDE OF SUNRISE. OUTLOOK...
