AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 318 PM EDT FRI JUN 13 2008 .SYNOPSIS... A WARM AND HUMID AIRMASS WILL BLANKET CENTRAL PENNSYLVANIA THROUGH SATURDAY MORNING. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL AFFECT MAINLY THE HIGHER TERRAIN OF WESTERN PENNSYLVANIA THROUGH THE MID MORNING HOURS SATURDAY. A COLD FRONT WILL CROSS THE AREA ON SATURDAY...BRINGING MORE NUMEROUS SHOWERS AND SCATTERED STRONG THUNDERSTORMS. SUNDAY WILL BE DRY...WITH NEAR NORMAL TEMPERATURES. A SECOND COLD FRONT SWEEP THROUGH THE REGION ON MONDAY BRINGING ANOTHER ROUND OF SCATTERED SHOWERS AND THUNDERSTORMS. BEYOND MONDAY...WE WILL SEE BELOW NORMAL TEMPERATURES AND CONTINUED UNSETTLED WEATHER. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... A WEAK MID LEVEL THERMAL TROUGH...COMBINED WITH A 925-850 HPA THETA-E RIDGE ACROSS THE WRN MTNS...OF PENN WILL LEAD TO FAIRLY NUMEROUS SHOWERS AND SCTD TSRA THROUGH EARLY THIS EVENING. DRIER AND SLIGHTLY WARMER AIR ALOFT WILL COMBINE WITH THE WANING MIXED LAYER CAPE LATE TODAY/TONIGHT TO SHIELD CENTRAL AND ERN PENN FROM MUCH MORE THAN A BRIEF...STRAY SHRA OR TSRA. THE BEST INSTABILITY AND LVLL FORCING (VIA THE SE EXTENT OF THE LAKE BREEZE CONVERGENCE ZONE...AND INCREASING SW 850 WINDS) WILL OCCUR ACROSS OUR FAR NW ZONES (WARREN...MCKEAN AND ELK COUNTIES) THROUGH THIS EVENING. ITS NOT OUT OF THE QUESTION TO SEE SOME SPECIAL WEATHER STATEMENTS AND A FEW SVRS BEING ISSUED FOR SOME 50-60 DBZ REFLECTIVITY CORES BRIEFLY EXCEEDING THE -20C LEVEL (AROUND 22 KFT AGL) ACROSS THIS AREA...AND TO A LESSER DEGREE ACROSS THE LAUREL HIGHLANDS. CONVECTIVE COVERAGE WILL DIMINISH QUICKLY BY LATER THIS EVENING WITH SCT-BKN ALTO CU AND JUST A LIGHT SOUTH TO SOUTHWEST BREEZE IN MOST LOCATIONS. ANOTHER ROUND OF UPSTREAM CONVECTION WILL ADVECT INTO OUR NW ZONES AFTER MIDNIGHT...SO WILL KEEP CHC POPS FOR SHRA/TSRA THERE. LIGHT AND VARIABLE WIND AND INCREASING LLVL MOISTURE WILL CREATE 3-5SM HAZE ACROSS THE CENTRAL AND ERN VALLEYS OVERNIGHT. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... A POTENT SHORTWAVE WILL TRACK NORTHEASTWARD THRU THE GRT LKS ON SATURDAY...PUSHING A COLD FRONT THROUGH THE AREA BY SAT AFTN. INCREASINGLY SOUTHWESTERLY LLVL FLOW AHEAD OF FRONT WILL ADVECT IN HIGHER DEW POINTS WHICH...COMBINED WITH DAYTIME HEATING...WILL LEAD TO MODERATE INSTABILITY. HOWEVER...MODEL DEEP LYR WIND SHEAR IS NOT TOO IMPRESSIVE AND IS STRONGEST TO THE NORTH OF OUR AREA...INDICATING THAT ORGANIZED/WIDESPREAD SVR WX NOT LIKELY. MAX TEMPS SATURDAY WILL BE A FEW DEG LOWER ACROSS THE CENTRAL AND SE ZONES...AND UP TO 5-7F LOWER ACROSS THE NW MTNS THANKS TO THE EARLIER PASSAGE OF THE COLD FRONT...AND MORE NUMEROUS SHOWERS/TSRA THROUGH THE MID AFTERNOON. KEPT LOW POPS FOR A SHRA/TSRA SAT EVENING ACROSS THE CENTRAL AND SE ZONES...BEFORE DRIER AND COOLER LLVL AIR PUSHES SE INTO THE REGION. ERODING CLOUD COVER ACROSS THE NW MTNS AFTER MIDNIGHT WILL ALLOW TEMPS TO DIP INTO THE 40S...WITH MINS ELSEWHERE IN THE 50S TO LOWER 60S. && .LONG TERM /SUNDAY THROUGH FRIDAY/... SUNDAY WILL BE PARTLY TO MOSTLY SUNNY AND DRY BEHIND THE FRONT...AND TEMPERATURES WILL BE SEASONABLE...IF NOT A BIT ON THE WARM SIDE...FOR MID-JUNE. THE NEXT FRONTAL SYSTEM ARRIVES ON MONDAY...ACCOMPANIED BY ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS. TUESDAY THROUGH FRIDAY LOOK TO BE COOLER-THAN-NORMAL AS THE REGION IS ENTRENCHED IN THE NORTHWESTERLY FLOW BEHIND THIS FRONT. THE WEATHER WILL BE A BIT UNSETTLED THROUGH THE PERIOD AS WELL...AS AN UPPER-LEVEL TROUGH POSITIONS ITSELF OVER THE EASTERN UNITED STATES. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... MAINLY VFR CONDITIONS EXPECTED THROUGH THE PERIOD EXCEPT FOR SOME SHORT DURATION DROPS TO MVFR OR IFR IN SCATTERED THUNDERSTORMS. CURRENTLY AN AREA OF THUNDERSTORMS MOVING TOWARDS JOHNSTOWN WHICH MAY BRIEFLY REDUCE VISIBILITY. LOW LEVEL SOUTHERLY WINDS BRINGING INCREASED MOISTURE INTO THE AREA... THIS COMBINED WITH DAY TIME HEATING WILL ALLOW FOR MORE SCATTERED THUNDERSTORMS TO DEVELOP THIS AFTERNOON. THE BEST THREAT APPEARS TO BE FROM STATE COLLEGE AND WESTWARD AS STORMS MOST LIKELY TO FORM OVER THE ELEVATED ALLEGHENIES AND HIGHER 850 HPA THETA-E AIR. CONDITIONS CLEAR OUT TONIGHT AFTER ANY EVENING SHOWERS WIND DOWN. THEREFORE EXPECT VFR CONDITIONS TO PREVAIL REGION WIDE. AREAS OF MVFR HAZE ARE POSSIBLE ESPECIALLY ACROSS THE SUSQUEHANNA VALLEY WHERE WINDS WILL BE LIGHT AND VARIABLE. A COLD FRONT WILL APPROACH THE AREA ON SATURDAY BRINGING MORE SHOWERS AND THUNDERSTORMS. EXPECT CLOUDS BASED MAINLY BETWEEN 6-10 KFT AGL TO BEGIN APPROACHING IN THE EARLY MORNING ACROSS THE CENTRAL AND WEST AND NOT TILL LATE MORNING NEAR HARRISBURG. AN AREA OF SHOWERS AND THUNDERSTORMS SHOULD THEN MOVE ACROSS THE AREA STARTING AROUND 8AM ACROSS BRADFORD TO 11AM AT STATE COLLEGE AND 2PM AT HARRISBURG. WHEN THIS AREA MOVES THROUGH SOME LOCATIONS MAY DROP TO MVFR OR IFR IN THE HEAVIEST STORMS. THIS IS MOST LIKELY ACROSS OUR EASTERN AREAS WHERE THE SUN WILL STAY OUT THE LONGEST LEADING TO GREATER INSTABILITY. SOME OF THE STORMS THAT MOVE THROUGH THIS AREA MAY PRODUCE GUSTY WINDS AND SMALL HAIL. VFR CONDS LIKELY TO PREDOMINATE SUNDAY...AS A RIDGE OF HI PRES BUILDS OVR THE STATE. HOWEVER...BRIEF CIG/VSBY REDUCTIONS ARE POSSIBLE IN SCT TSTMS MONDAY AS ANOTHER COLD FRONT PUSHES INTO THE REGION. MAINLY DRY WEATHER (WITH VFR CONDITIONS) AND NOTICEABLY COOLER TEMPS WILL OVERSPREAD THE REGION MONDAY NIGHT THROUGH WEDNESDAY. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...FITZGERALD/LAMBERT NEAR TERM...FITZGERALD/LAMBERT SHORT TERM...FITZGERALD/LAMBERT LONG TERM...DANGELO/EVANEGO AVIATION...LAMBERT/RXR
