AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 801 PM EDT TUE JUN 26 2007 .SYNOPSIS... BERMUDA HIGH WILL CONTINUE TO PUMP UP THE MOISTURE OVER PA...AND MAKE IT HOT AND HUMID INTO WEDNESDAY. A COLD FRONT WILL PUSH THROUGH THE REGION ON THURSDAY PROVIDING THE BEST CHANCE FOR WIDESPREAD PRECIPITATION ACROSS THE REGION. IN THE WAKE OF THE COLD FRONT...HIGH PRESSURE WILL BRING AN UNSEASONABLY COOL AND DRY AIRMASS SOUTH FROM CANADA...AND PROVIDE RELIEF FROM THE HEAT AND HUMIDITY INTO THE UPCOMING WEEKEND. && .NEAR TERM /UNTIL 10 PM THIS EVENING/... LATEST RADAR SHOWS ISOLD PULSE CONVECTION ACROSS THE RIDGES OF THE LAUREL AND SOUTH CENTRAL MTNS...AS WELL AS THE SOUTH MOUNTAIN AREA IN ADAMS/YORK COUNTIES. THESE SLOW MOVING STORMS HAVE PRODUCED LOCALLY HEAVY RAINFALL ON THE ORDER OF 1-2 INCHES IN SPOTS. ISSUED A SVR FOR CENTRAL BLAIR COUNTY ON A STORM WITH 65-70 DBZ CORE JUST ABOVE THE FZG LVL /15KFT/ AND A NICE THREE BODY SCATTER SPIKE (TBSS). THIS STORM WAS IN A REMOTE LOCATION BTWN HOLLIDAYSBURG AND WILLIAMSBURG...CLOSE TO RT 22...BUT NO VERIFICATION AS OF YET. DESPITE THE STRONG ELEVATED CORE...TEMPS ALOFT MAY HAVE BEEN TOO WARM. DIURNALLY DRIVEN CONVECTION WILL WEAKEN/DISSIPATE WITH THE LOSS OF HEATING LATER THIS EVE. && .SHORT TERM /10 PM THIS EVENING THROUGH THURSDAY NIGHT/... IT WILL BE WARM AND MUGGY TONIGHT WITH LOWS IN THE 60S ACROSS THE WESTERN/CENTRAL MTNS TO LOW 70S ACROSS THE URBAN AREAS OF THE LWR SUSQ VLY. LOOK FOR PATCHY FOG TO DEVELOP AFT MIDNIGHT...BCMG LCL DENSE ACROSS THE LWR SUSQ VLY. SFC COLD FRONT MOVES THROUGH THE GRT LKS AND APPROACHES FROM THE NORTHWEST WEDNESDAY. PRE-FRONTAL WARM/MOIST AIRMASS WILL SUPPORT MAXES CLOSE TO OR EVEN SLIGHTLY WARMER THAN TODAY. THE HEAT AND HUMIDITY WILL COMBINE TO CREATE HEAT INDEX VALUES IN THE MID 90S ACROSS THE LWR SUSQ VLY WHERE SFC DEWPOINTS WILL LINGER NEAR OR JUST ABOVE 70F. AS WAS THE THINKING YESTERDAY...SPC HAS DROPPED THE SLIGHT RISK FOR WED GIVEN SLOWER FRONTAL PROGRESSION. THE STRONGEST LLVL CONVERGENCE AND OVERALL BEST LIFT WILL REMAIN TO THE NW CLOSER TO THE SFC FRONT. HOWEVER...FOCUS FOR AFTN CONVECTION MAY BE A LEE SFC TROF SETTING UP IN ADVANCE OF THE COLD FRONT. MUCH LIKE TODAY...STRONG SFC HEATING WILL OVERCOME WEAKLY CAPPED AIRMASS RESULTING IN DIURNALLY DRIVEN AFTN CONVECTION. A SLIGHTLY STRONGER DEEP-LYR WIND FIELD WOULD FAVOR A FEW MORE SVR STORMS...BUT OVERALL THREAT STILL REMAINS LOW. FROPA TIMING BASED ON THE LATEST MODEL/ENSEMBLE GUID APPEARS TO BE THURSDAY AND HAVE INCREASED POPS INTO THE LKLY CAT...WHICH AGREES WITH LATEST MOS/SREF/MREF GUID. DY3 SLIGHT RISK LOOKS VERY REASONABLE...GIVEN WARM/MOIST AIRMASS AHEAD OF THE FRONT AND HAVE INCLUDED MENTION IN THE HWO. THE FRONT SLOWLY SAGS SWD THROUGH THE STATE INTO THURSDAY NIGHT WILL SHWRS LINGERING ACROSS THE SRN TIER. GRADUALLY TAPER POPS FROM N-S CLEARING MOST AREAS OUT BY EARLY FRI MORNING. && .LONG TERM /FRIDAY THROUGH TUESDAY/... MUCH COOLER AND DRIER AIR WILL ACCOMPANY HIGH PRESSURE AS IT MOVES SEWD OUT OF CANADA AND INTO THE REGION IN THE WAKE OF THE COLD FRONT. THE TRULY CP AIRMASS WILL TRANSLATE INTO MAX TEMPS COOLER THAN CLIMO. AS THE HIGH GRADUALLY SHIFTS OFFSHORE BY EARLY NEXT WEEK...ENSUING WARM ADV REGIME WILL ALLOW TEMPERATURES TO REBOUND BACK TOWARD MORE SEASONABLE READINGS. UPPER LEVEL PATTERN TRANSITIONS TO A PREDOMINANT NWLY FLOW WITH EMBEDDED S/W DISTURBANCES DIVING SEWD ACROSS THE UPPER MIDWEST. WILL CONTINUE TO KEEP LATER PDS DRY GIVEN LOW PREDICTABILITY OF THE LARGE SCALE FLOW. OVERALL...NOT MANY CHANGES LONG TERM AND HAVE BLENDED LATEST GMOS/HPC GUID WITH PREVIOUS FCAST. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... DIURNALLY DRIVEN TSTMS AROUND KJST AREA SHOULD BEGIN TO DISSIPATE OVER THE NEXT FEW HOURS...OTHERWISE VFR ACROSS THE STATE THROUGH THE EVENING. UNDER SUBTROPICAL RIDGE...HIGH HUMIDITY WILL ALLOW FOR WIDESPREAD FOG FORMATION...PARTICULARLY IN THE MID AND LOWER SUSQUEHANNA...AND WILL RESULT IN EXTENDED PERIODS OF MVFR/IFR CONDITIONS. ONCE FOG BREAKS TOMORROW MORNING...MUCH OF THE DAY WILL BE VFR UNTIL MORE DIURNALLY DRIVEN TSTMS DEVELOP AGAIN. FRONT WILL CROSS THE STATE OVERNIGHT WEDNESDAY INTO THURSDAY WHICH WILL PRODUCE MORE SHOWERS AND THUNDERSTORMS. ONCE THIS SYSTEM CLEARS...COOL DRY HIGH PRESSURE BUILDS IN AND VFR CONDITIONS WILL DOMINATE THROUGH THE END OF THE WEEKEND. && .CTP WATCHES/WARNINGS/ADVISORIES...
