Area forecast discussion, Jul 18, 3:47 PM EDT, 3 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 347 PM EDT SAT JUL 18 2015 .SYNOPSIS... AN UPPER LEVEL RIDGE WILL BUILD OVER THE NORTHEAST CONUS THIS WEEKEND. A SHORT WAVE PASSING TO THE NORTH WILL PUSH A COLD FRONT THROUGH PENNSYLVANIA SUNDAY NIGHT AND EARLY MONDAY. HIGH PRESSURE WITH COOLER AND DRIER WEATHER WILL BUILD SOUTHEAST INTO PENNSYLVANIA ON WEDNESDAY...AND REMAIN ACROSS THE AREA THROUGH FRIDAY. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... STIFLING HUMIDITY AND BUILDING HEAT WILL BE THE MAIN STORY TODAY AND AGAIN ON SUNDAY...AFTER PASSAGE OF SHORTWAVE WHICH TRIGGERED HEAVY RAIN-PRODUCING THUNDERSTORMS ACROSS CENTRAL PA THIS MORNING. SLOWLY RISING HEIGHTS ALOFT WITH UPPER RIDGE AXIS ALIGNED OVER CENTRAL PA THIS AFTERNOON HAS GIVEN A NICE SEVERAL HOUR BREAK IN CONVECTIVE ACTIVITY AFTER LAST NIGHT'S COPIOUS CONVECTIVE RAINFALL OVER ESPECIALLY THE CENTRAL MOUNTAINS. ONLY SHALLOW CLOUD TURRETS SEEN ON VISIBLE IMAGERY...BUT LEE TROFFING AND STRONG SFC HEATING SHOULD PRODUCE ISOLD-SCT DIURNAL TSRA TO DEVELOP. GREATEST COVERAGE OF CONVECTION WILL LIKELY BE ALONG AXIS OF HIGHEST PWATS OVER EASTERN PA...IN VICINITY OF LEE SFC TROF. ARRIVAL OF UPPER RIDGE AXIS AND ASSOC WARM TEMPS ALOFT SHOULD REALLY LIMIT VERTICAL GROWTH OF TOWERS AND COVERAGE OF STORMS ACROSS THE NW COUNTIES. HIGH CAPE AND WEAK SHEAR IMPLIES A LOW END THREAT OF ISOLD PULSE TYPE SVR STORMS...AND LOCALLY HEAVY RAINFALL INTO EARLY EVENING FROM ANY STORMS. THE OVERNIGHT SHOULD BE MAINLY FAIR...WITH PATCHY FOG FORMING IN THE EXTREMELY MUGGY AIR MASS. IT WILL BE QUITE UNCOMFORTABLE FOR SLEEPING TONIGHT. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... WE ARE STILL EXPECTING THE HOTTEST DAY OF THE SUMMER THUS FAR... WITH COMBINATION OF EXCESSIVE DEWPOINTS AND AFTERNOON MAX TEMPS IN THE LOWER TO MIDDLE 90S TO CREATE HEAT INDICES BETWEEN 100F AND 104F OVER THE LOWER TO MIDDLE SUSQ RIVER VALLEY AND SOUTH CENTRAL MOUNTAINS. HEAT ADVISORY ISSUED FOR THIS...VALID FROM 16Z SUN THROUGH 02Z MONDAY. THE HEAT AND HUMIDITY...ALONG WITH APPROACHING LATE DAY UPPER TROF FROM THE EASTERN GLAKS WILL ALSO BRING A SLIGHT RISK OF SEVERE THUNDERSTORMS TO WESTERN AND CENTRAL SECTIONS SUN AFTERNOON AND EVENING. CAPES IN EXCESS OF 2000 J/KG AND INCREASING DEEP LAYER SHEAR WILL BRING THE THREAT FOR ORGANIZED BOWING LINE SEGMENTS. 850 MB TEMPS AROUND 20C WILL PRODUCE HIGHS RANGING FROM THE UPPER 80S OVR THE ALLEGHENY MTNS...TO THE M90S ACROSS THE LOWER SUSQ VALLEY. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... A SERIES OF COLD FRONTS WILL CROSS THE KEYSTONE STATE THROUGH TUESDAY. HIGH PRESSURE WILL BUILD SE AND BRING LESS HUMID CONDITIONS TO THE AREA FOR MID TO LATE WEEK. DID NOT CHANGE A LOT. DID UP TEMPS AND DEWPOINTS SOME FOR THE FIRST PART OF THE WEEK...GIVEN THE AIRMASS IN PLACE AND FCST TO BE IN PLACE. DID LOWER TEMPS SOME AFTER TUE...GIVEN THE PATTERN WE BEEN IN. ALSO 500 MB HEIGHTS FCST ON LATER RUNS ARE LOWER NOW...AND WET GROUND CONDITIONS. DID NOT DO MUCH WITH POPS. WENT WITH A DRY FCST AFTER TUE. WENT WITH A DRY SOLUTION FOR NEXT SAT...BASED ON HPC CHARTS. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... ISOLD MVFR CIGS EXPECTED INTO THIS EVENING WITH POP UP THUNDERSTORMS. RIDGING ALOFT WILL WORK AGAINST THE INSTABILITY... BUT THE BEST CHC FOR CONVECTION WILL BE IN THE LEE SURFACE TROF OVER THE LOWER TO MIDDLE SUSQUEHANNA RIVER VALLEY.
