AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 303 PM EDT MON JUN 17 2013 .SYNOPSIS... A SERIES OF WEAK SURFACE FRONTS WILL CROSS THE COMMONWEALTH TONIGHT AND TUESDAY. GENERALLY DRY WEATHER WILL FOLLOW FOR THE SECOND HALF OF THE WEEK AS A LARGE AREA OF HIGH PRESSURE BUILDS INTO THE REGION. ABOVE NORMAL TEMPERATURES WITH INCREASING HUMIDITY ARE EXPECTED FOR NEXT WEEKEND AS WARM AIR FROM THE CENTRAL STATES MOVES TO THE EAST. && .NEAR TERM /UNTIL 11 PM THIS EVENING/... SFC TROUGH/FRONT NOW LIT UP ALONG THE NRN TIER BUT IT IS WORKING INTO VERY DRY AIR - NEAR 50F DEWPOINTS IN THE CENTRAL MTS. THE SHOWERS MAY MAKE A RUMBLE OR TWO OF THUNDER...BUT THEY ARE VERTICALLY CHALLENGED WITHOUT MOISTURE TO FUEL THEM AND MAKE THEM GROW TALL ENOUGH TO GLACIATE AND PRODUCE LIGHTNING. WINDS COULD GUST INTO THE 30S...BUT NOT LIKELY ANY WORSE. BETTER DEWPOINTS POOLING UP OVER NERN OH ATTM...AND SH/TSRA THERE CURRENTLY COULD SLIDE INTO WRN PA LATER THIS EVENING. HEAT AND MUCH BETTER DEWPOINTS ALONG THE OLDER FRONT OVER THE SRN TIER ALSO FIRING A FEW SHRA. AGAIN...ISOLD T POSSIBLE...BUT NO WORRY FOR SEVERE WEATHER. THE SHOWERS SHOULD DWINDLE AS THE NIGHT STARTS AND STABILIZATION OCCURS. HOWEVER...ANOTHER FRONT - THIS ONE WITH REAL DRY AIR BEHIND IT - LURKS JUST S OF LAKE ONTARIO AT THIS TIME. IT WILL ALSO ONLY MOVE SLOWLY TO THE SOUTH. && .SHORT TERM /11 PM THIS EVENING THROUGH 6 PM TUESDAY/... ANY BREAK IN RADAR ECHOES ON THE KCCX SCOPE WILL PROBABLY BE ONLY A FEW HOURS...AS MORE FORCING SLIDES ACROSS THE LOWER GREAT LAKES TONIGHT. THIS WILL MEET UP WITH THE THIRD FRONT TO PRODUCE SCT SHRA LATER TONIGHT IN THE N/W. WILL LEAVE POPS IN THE CHC RANGE FOR NOW DUE TO MODEL DIFFERENCES IN PLACEMENT OF ANY CONVECTIVE DEVELOPMENT. THIS MAIN/THIRD FRONT SHOULD CONTINUE TO TREK THROUGH THE REGION ON TUESDAY AND WILL MAKE THE POPS MUCH MORE WIDESPREAD/HIGHER. PWATS REACH NEAR AN INCH AND A HALF ON TUES...WHICH COULD COMBINE WITH SLOWLY MOVING CELLS TO MAKE A BRIEF HEAVY DOWNPOUR. BUT FFG VERY HIGH AND THREAT FOR FLOODING VERY LOW. THIS FRONT...TOO..MAY WASH OUT AS IT REACHES THE SRN BORDER. && .LONG TERM /TUESDAY NIGHT THROUGH MONDAY/... BROAD TROUGH OVER NORTHEAST U.S. WILL BRING AN UNSETTLED START TO THE WEEK...BUT RIDGE BUILDING IN STARTING MIDWEEK WILL BRING DRY AND COOLER WEATHER BEFORE MORE HUMID AND SHOWERY CONDITIONS RETURN FOR THE WEEKEND. NORTHERLY FLOW DEVELOPS TUE NIGHT INTO WED AS HIGH PRESSURE BUILDS SOUTHWARD ACROSS GLAKES...WHICH WILL KICK THE FRONTAL BOUNDARY FURTHER SOUTH AND USHER IN BEGINNING OF A PERIOD OF DRIER AND COOLER WEATHER. WE/LL SEE A FEW CHILLIER NIGHTS...ESP ACROSS THE NORTH /THE COLDEST BEING WED NIGHT WITH READINGS DIPPING INTO THE 40S NORTH OF I-80/ AS HIGH SETTLES IN. BUT SOUTHWESTERLY RETURN FLOW BEGINS ON THU AS RIDGE AXIS DRIFTS TO OUR EAST. AS LOWER LEVELS BEGIN TO SLOWLY MOISTEN BACK UP...ISOLATED LATE DAY TSTMS AGAIN BECOME POSSIBLE OVER SOUTHERN HALF THU AND ESP FRI. HEIGHTS RISE HEADING INTO THE WEEKEND. SURGE OF MOISTURE ALSO GETS SHUNTED EASTWARD FROM THE CENTRAL U.S. BRINGING A NOTICEABLE INCREASE IN THE HEAT AND ESPECIALLY HUMIDITY. TSTM PROBABILITIES INCREASE SAT...PEAKING ON SUNDAY BEFORE A COLD FRONT DROPS ACROSS THE GLAKES EARLY NEXT WEEK BRINGING A GRADUAL CHANGE IN AIRMASS BACK TOWARD DRIER CONDITIONS. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... FRONT NUMBER 1 IS STILL OVER THE SERN COS AND PROVIDING A FOCUS FOR SH/TSRA THERE. THESE SHOULD WANE AS THE HEATING WANES...BUT COULD BRING VISBYS INTO IFR FOR A BRIEF TIME AT LNS/MDT. ANOTHER FRONT IS DROPPING THRU THE NRN MTS AND SHOULD ARRIVE IN THE CENTRAL MTS AND MID SUSQ SHORTLY. MUCH BETTER COVERAGE ALONG THAT FRONT - BUT IT IS MOVING INTO VERY DRY AIRMASS OVER UNV/AOO. WILL KEEP MENTIONS OF SHOWERS IN FOR MOST LOCATIONS AS UPSTREAM STORMS OVER NERN OH WILL MOST LIKELY SLIDE INTO WRN PA AS WELL. MORE FORCING COMES DOWN FROM THE UPPER GREAT LAKES TONIGHT AND PAIRS UP WITH YET ANOTHER FRONT - WHICH HAS THE BEST DRYING BEHIND IT. THIS FRONT IS ALREADY INTO WRN NY STATE BUT NOT MOVING VERY MUCH AT ALL. WILL THEREFORE BRING THE CHC OF SHOWERS BACK INTO BFD AFTER MIDNIGHT. WILL HOLD OFF ON MENTIONING SHOWERS FOR THE DAYTIME ON TUES DUE TO UNCERTAINTY IN PLACEMENT AND TIMING. BUT SCT/NMRS SHRA/TSRA EXPECTED ON TUESDAY AS THAT REAL DRY AIRMASS MOVES ACROSS THE AREA. CLEARING SKIES AND CALM AIR WILL ALLOW FOG TO FORM...PERHAPS GOING IFR IN SOME VALLEY LOCATIONS...ESP THOSE WHICH PICK UP SOME RAIN TODAY. OUTLOOK... WED-FRI...NO SIG WX EXPECTED. SAT...SCT TSRA POSS. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...DANGELO NEAR TERM...DANGELO SHORT TERM...DANGELO LONG TERM...DEVOIR/RXR AVIATION...DANGELO
