NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 12, 3:29 PM EST, 2 hours 31 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PITTSBURGH PA 429 PM EDT THU JUN 12 2014 .SYNOPSIS... ALTHOUGH SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH FRIDAY...THE WEEKEND WILL BE DRY. && .NEAR TERM /THROUGH FRIDAY/... HAVE CANCELLED FLASH FLOOD WATCH FOR THE AREA. COVERAGE AND INTENSITY OF THUNDERSTORMS NOT ENOUGH TO CREATE WIDESPREAD FLOOD THREAT. SCATTERED SHOWERS/ISO STORMS WILL CONTINUE THROUGH THE EVENING HOURS AS SLOW MOVING SHORTWAVE TROUGH SWINGS THROUGH. MOST OF THE HEAVIER ACTIVITY WILL BE ALONG THE RIDGES WHERE HIGHER TDS AND BEST MOISTURE CONVERGENCE IS LOCATED. EXPECT THE ACTIVITY TO WEAKEN AND DISSIPATE WITH THE LOSS OF SUNSHINE. PREVIOUS DISCUSSION... CONVECTION HAS SPREAD ACROSS MUCH OF THE REGION AGAIN TODAY...SIMILAR TO YESTERDAY. HOWEVER...THE WIDESPREAD SEVERE WEATHER THAT HAPPENED YESTERDAY IS NOT EXPECTED THIS AFTERNOON INTO THIS EVENING. THROUGH THE EARLY AFTERNOON...LIGHTNING ITSELF HAS BEEN QUITE SPARSE ACROSS THE AREA. INSTABILITY AND WIND SHEAR ARE MARGINAL OVERALL...WITH A FEW STRONGER STORMS STILL A POSSIBILITY. THE GREATER CONCERN THIS AFTERNOON/EVENING IS FLASH FLOODING DUE TO SLOW STORM MOVEMENT AND INCREASING MOISTURE. SHOWERS ARE MOVING AROUND 10 MILES PER HOUR...AND PRECIPITABLE WATER VALUES ARE ABOUT 50 PERCENT ABOVE NORMAL. CONSIDERING THAT MANY LOCATIONS IN PENNSYLVANIA AND WEST VIRGINIA RECEIVED AT LEAST AN INCH OF RAINFALL ON WEDNESDAY...ANOTHER INCH OF RAIN IN 3 HOURS IN THOSE LOCATIONS COULD POTENTIALLY CAUSE FLOODING. SEE NO REASON TO MAKE ANY CHANGES TO THE FLASH FLOOD WATCH WHICH WILL REMAIN IN EFFECT THROUGH LATE EVENING. A BIT OF A BREAK SETS UP OVERNIGHT WITH THE UPPER LEVEL JET PRODUCING FORCING FOR PRECIPITATION MOVING OFF TO THE NORTH AND THE SURFACE COLD FRONT REMAINING TO THE WEST. CHANCES FOR RAIN WILL PICK UP AGAIN DURING THE MORNING WITH THE COLD FRONT MOVING TO THE EAST. HAVE REMOVED LIKELY POPS FROM THE FORECAST WITH CONFIDENCE LACKING ABOUT JUST HOW WIDESPREAD SHOWER COVERAGE IS. A SEVERE THREAT IS NOT EXPECTED TOMORROW...AND THE FRONT IS EXPECTED TO MOVE QUICKLY ENOUGH THAT FLOODING WOULD NOT BE AN ISSUE AS WELL. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... WITH THE CURRENT TIMING OF THE FRONT...STILL THINK THAT THERE COULD BE AN ISOLATED SHOWER ACROSS THE RIDGES FRIDAY EVENING...BUT THE WEEKEND ITSELF SHOULD BE DRY THANKS TO HIGH PRESSURE MOVING FROM ILLINOIS TO THE ATLANTIC COAST DURING THE PERIOD. LOW TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL ALONG WITH HIGHS ON SATURDAY...BUT A SHIFT IN WINDS FROM THE NORTHWEST TO THE SOUTH WILL BRING WARMER TEMPS ON SUNDAY. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... UPPER LEVEL RIDGE AXIS SHIFTS WELL EAST OF THE AREA SUNDAY NIGHT AS A DEEPENING LOW PULLS OUT OF THE ROCKIES AND ACROSS THE UPPER PLAINS. A RELATIVELY DRY COLD FRONT POSITIONED SOUTH OF THE LOW WILL APPROACH THE AREA AT THE BEGINNING OF NEXT WEEK. WITH UPPER LEVEL FLOW TRANSITIONING TO MORE A ZONAL REGIME AND ROUGHLY PARALLEL TO THE BOUNDARY MON/TUES...THE FRONT LOOKS TO STALL IN THE NEIGHBORHOOD. THIS STALLED BOUNDARY WILL ACT AS A FOCUS FOR MULTIPLE WAVES PASSING THROUGH MIDWEEK WITH RAIN AND THUNDERSTORM CHANCES COMMON. THE RIDGE TRIES TO RE-ESTABLISH TOWARDS THE LATTER PART OF NEXT WEEK. && .AVIATION /21Z THURSDAY THROUGH TUESDAY/... ANY REMAINING MVFR CIGS SHOULD IMPROVE TO VFR THRU THE AFTN. A SLOW MOVG UPR TROF WL ADVN TWD THE AREA THIS AFTN WITH SCT-NMRS SHWRS AND TSTMS EXPD. INCLUDED VCTS FOR A BRIEF PD E OF ZZV... WITH A TEMPO PD E OF PIT WHERE INSTBY IS MORE FAVORABLE TO SEE TSTMS BASED ON LATEST INSTBY CHARTS AND MESO DATA. AFT CNVCTN DCRS WITH DMNSHG INSTBY THIS EVE...EXP AT LEAST MVFR CONDS IN STRATUS AND FOG LT TNGT INTO ERLY FRI MRNG. IFR IS PSBL BUT WL NOT MENTION ATTM DUE TO UNCERTAINTY OF REMAINING LLVL MOISTURE. VFR SHOULD RTN FRI AFTN...THOUGH A CROSSING CDFNT MAY BRING A FEW SHWRS OR A TSTM. .OUTLOOK.../FRIDAY NIGHT THROUGH TUESDAY/... A DISTURBANCE WL RTN RSTRN CHCS MON AND TUE. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
