AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 743 PM EDT THU JUN 26 2008 .SYNOPSIS... A PROGRESSIVE UPPER LEVEL FLOW PATTERN COMBINED WITH INCREASING HEAT AND HUMIDITY WILL LEAVE CENTRAL PENNSYLVANIA VULNERABLE TO SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE REMAINDER OF THE WORK WEEK. A SHARP COLD FRONT WILL LIKELY BRING NUMEROUS SHOWERS AND THUNDERSTORMS THIS WEEKEND...SOME OF WHICH MAY BE SEVERE. AN ANOMALOUS UPPER LEVEL TROUGH OF LOW PRESSURE WILL BECOME ESTABLISHED OVER THE EASTERN U.S. BY EARLY NEXT WEEK LEADING TO COOLER TEMPERATURES AND DIURNAL SHOWERS AND THUNDERSTORMS. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... LATEST VISIBLE SAT IMAGERY SHOWS DEC CLOUDS ACROSS CENTRAL PENN. THE INCREASED INSOLATION SHUD ALLOW TEMPS TO NEAR/EXCEED CONVECTIVE TRIGGERS...WHICH COULD LEAD TO THE DEVELOPMENT OF LATE AFTN RW/TRW. VIS SAT TRENDS TO THE WEST SUGGEST AIRMASS IS BECOMING INCREASINGLY UNSTABLE AS THE ENHANCED CU FIELD OVER THE OH VLY IS MOVG PARALLEL TO THE LLVL FLOW. COMPACT S/W SLIDING EWD ACROSS NRN ID MAY ALSO ACT TO ENHANCE FORCING FOR ASCENT...WITH THE BEST CHC OF PCPN ACROSS WRN PA. SPC SLIGHT RISK AREA HAS NOW BEEN ADJUSTED FURTHER TO THE WEST OUT OF MY CWA. THE AFOREMENTIONED UPSTREAM S/W MAY KICK OFF SOME PCPN LATER TNT. HOWEVER...MESOSCALE PREDICTABILITY WITH THESE FEATURES IS QUITE LIMITED THUS LOW CONFIDENCE IN ANY ONE PARTICULAR LOCATION. SREF ENS POPS SUGGEST THE HIGHEST CHC POPS OVER THE WRN COUNTIES. && .SHORT TERM /FRIDAY THROUGH SUNDAY/... GFS/NAM DIFFER ON THE LOCATION OF CONVECTION FOR FRIDAY GIVEN THE LACK OF A TRUE FOCUSING MECHANISM. INCREASING HEAT/HUMIDITY COMBINED WITH COMPACT S/W DISTURBANCES TRANSLATING W-E IN THE ZONAL FLOW ALOFT SHOULD LEAD TO ISOLD TO SCT AFTN RW/TRW AND THE POTENTIAL FOR CONVECTIVE COMPLEX/S FRI NGT. WEAK DEEP LYR WIND FIELD SUGGESTS PULSE TYPE STORMS WITH THE BULK OF THE CONVERGENCE COMING FROM TERRAIN INFLUENCES DURING THE DAY. BETTER PROBABILITIES FOR SHOWERS AND T-STORMS STATEWIDE THIS WEEKEND AS A COLD UPPER LVL TROF MIGRATES EWD ACROSS THE UPPER PLAINS/WRN GLKS. AMPLE LARGE SCALE ASCENT COMBINED WITH INCREASINGLY STRONG WIND FIELDS ALOFT AND MOIST/UNSTABLE PRE- FRONTAL WARM SECTOR AIRMASS SHOULD SUPPORT NUMEROUS TO WIDESPREAD STG TO SEVERE STORMS. SPC DY3 HAS ALL OF THE CWA IN SLIGHT RISK. THE MAIN CLD FNT WILL LKLY SLOW AS THE LARGE SCALE PATTERN FURTHER AMPLIFIES INTO SUNDAY. A SEVERE THREAT WILL STILL EXIST OVER ERN PA AS THE CLD FNT TRAVERSES THROUGH THE STATE. HIGH CHC/LOW LKLY POPS STILL LOOK GOOD FOR SAT/SUN. && .LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/... GFS ENS MEAN SHOWS AN ANOMALOUS UPPER LVL TROF BECOMING ESTABLISHED ACROSS THE ERN U.S. BY EARLY NEXT WEEK. SCT DIURNAL RW/TRW WILL BE PSBL ON MON. FAIR/COOL WX SHOULD PERSIST INTO MID WEEK AS HIGH PRES MOVES INTO THE REGION. A MODERATING TREND LOOKS IN STORE TWD THE END OF NEXT WEEK BEHIND RETURN SWLY FLOW. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... VFR CONDITIONS AT THE CURRENT TIME...BUT REMAINS OF CONVECTION LIKELY TO RACE EASTWARD INTO THE WESTERN PORTION OF CENTRAL PA. I PUT THUNDER IN FOR MOST OF THE TAFS...BUT LEFT OUT OF IPT AND MDT. EXPECT FOG OVERNIGHT...ESPECIALLY WHERE IT RAINS. MVFR CONDITIONS LIKELY AFTER MIDNIGHT. FOR FRIDAY...EXPECT FOG AND HZ TO MIX OUT FAIRLY FAST...BUT WILL LIKELY LINGER IN MDT...AS FLOW BACKS THERE. STORMS MAY ONCE AGAIN POP UP DURING THE LATER MORNING OR EARLY AFTERNOON FRIDAY AS A WEAK SHORTWAVE MOVES THOUGH DURING THE MORNING. FOR NOW...LEFT MENTION OF STORMS OUT OF THE TAFS. ACTIVE WEATHER WILL CONTINUE THROUGH AT LEAST MONDAY WITH PERIODS OF SHOWERS AND THUNDERSTORMS POSSIBLE EACH DAY. THE BEST CHANCE OF WIDESPREAD STORMS APPEARS TO BE LATER SATURDAY INTO SUNDAY WITH THE PASSAGE OF A STRONG COLD FRONT. TROUGH WILL BUILD IN BEHIND FRONT LEADING TO AFTERNOON INSTABILITY SHOWERS AND THUNDERSTORMS MONDAY. TROUGH AXIS SHIFTS JUST EAST OF US TUESDAY MEANING VFR CONDITIONS SHOULD DOMINATE OTHER THAN A FEW STORMS IN FAR EASTERN ZONES. && .CTP WATCHES/WARNINGS/ADVISORIES...
