AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1125 AM EDT THU JUL 21 2005 .SHORT TERM (REST OF TODAY)... WEAK MCV FROM OVERNIGHT CONVECTION CONTINUES TO PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS OVER WESTERN PA THIS MORNING. RUC AND ETA BUFKIT SOUNDINGS INDICATE LITTLE IF ANY CAP...IN CONTRAST TO WHAT WAS SHOWN YESTERDAY. THUS...GIVEN THE MCV AS A TRIGGER AND INCREASING MOISTURE (LAYER PWS INCREASING TO 1.5+) WITH MOISTURE SURGE OVER WESTERN PA...WILL EXPAND POPS FOR THE AFTERNOON AND INCLUDE SCATTERED SHRA/TSRA FOR MUCH OF CENTRAL AND SOUTHERN SECTIONS EXTENDING INTO THE LOWER SUSQ. NOT EXPECTING SEVERE AT THIS TIME GIVEN WEAK SHEAR PROFILE...BUT GIVEN AVAILABLE MOISTURE AND EASTWARD PROPOGATION AT TIME OF MAX HEATING...WILL OBVIOUSLY NEED TO BE MONITORED FOR ANY PULSING. NO OTHER CHANGES AT THIS TIME. && .PREVIOUS DISCUSSION... (ISSUED 238 AM EDT THU JUL 21 2005) SHORT TERM (TODAY THROUGH FRIDAY NIGHT)... NO SHORTAGE OF WORRIES IN THE NEAR TERM...AS WHAT WAS GOING TO BE A PRETTY NICE/EASY WX DAY FOR CENTRAL PA HAS BEEN COMPLICATED BY THE APPROACH OF AN MCS THAT FORMED LAST EVENING OVER LWR MI AND NRN IN. THE SHOWERS AND THUNDER ARE NOW ALL THE WAY INTO NRN OH AND COMING ON-SHORE FROM LK ERIE AS WE SPEAK. THE UPPER FLOW AND GOOD MOISTURE FAVOR THIS GUY DROPPING TO THE SE THRU 12Z...BUT IT MAY BRUSH THE WRN FRINGES OF THE CWA BEFORE THAT. WILL ALLOW FOR THIS BY ADDING CHC POPS TO THE EXTREME WRN AREAS THIS MORNING...AND HOLDING THEM IN THE LAURELS THRU THE DAY...BUT DIPPING THEM TO 20S IN THE NWRN MTS/PLATEAU IN THE AFTN. THE DECENT CAP OVERHEAD (+8 TO +10C AT 7H) SHOULD LIMIT THE EASTWARD PROGRESSION OF THE SYSTEM...AND MAY KEEP MUCH THUNDER FROM OCCURRING. BUT WITH THINGS ALREADY GOING GOOD JUST TO OUR NW...WL MENTION THUNDER AS WELL. THE ADDITION OF SOME CLOUDS/DEBRIS FROM THE MCS WILL KEEP THINGS A BIT COOLER THAN EARLIER EXPECTED AS WELL. WILL KEEP MAXES BLO 90 IN MOST LOCALES...EXCEPT THE LWR SUSQ. ANY CONVECTION THIS AFTN SHOULD DIE AWAY FAST EARLY THIS EVENING. WILL ONLY CARRY A SLIGHT CHC POP IN THE SW FOR THE EVENING...THEN MAKE IT PRECIP FREE FOR THE REST OF THE NIGHT. FRIDAY LOOKS LIKE IT SHOULD START OUT DRY...TOO. BUT...A FAST (AND EVER-FASTER-PROGGED) MOVING COLD FRONT WILL DROP INTO THE STATE FROM THE NORTH/NORTHWEST DURING THE DAYTIME. OUR CAP WILL BE A BIT WEAKER ON FRIDAY (+6-8C)...SO WILL CARRY A CHC POP FOR MOST OF THE AREA IN THE AFTN AND EVENING...TAPERING TO SLIGHT CHCS FOR THE REST OF FRI NITE. DANGELO LONG TERM (SATURDAY THROUGH WEDNESDAY)... MAKE A MINOR TWEAK OR TWO TO POPS ON SAT/NITE TO GO WITH EVER-FASTER TREND OF THE FRONTAL MOVEMENT...BUT OVERALL NO REAL CHANGES MADE BEYOND THAT. CURR FCST IS GOOD WITH BIG PICTURE. INTERESTING PATTERN SHIFT MAY OCCUR LATE IN THE FCST TIME FRAME...AND MAY LEAD TO SUB-NORMAL TEMPS FOR THE END OF THE MONTH - WITH MREF MEAN 5H HEIGHTS HINTING THAT AN UPPER TROF WL DIG OVER THE ERN CONUS. DANGELO AVIATION... SOME MID AND HI CLDS TODAY...GIVEN WARM ADVECTION. A FEW SHOWERS AND STORMS COULD HOLD TOGETHER...BUT MOST AREAS WILL NOT SEE MUCH MORE THAN A SPRINKLE. MOST IF NOT ALL OF TODAY WILL BE VFR. ONCE SUN SETS TONIGHT...AND HIGHER DEWPOINTS WORK IN...SOME MVFR CONDITIONS LIKELY IN BR. MARTIN && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...DEVOIR
