AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 1258 AM EDT FRI JUN 13 2014 .SYNOPSIS... ALTHOUGH SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH FRIDAY...THE WEEKEND WILL BE DRY. && .NEAR TERM /THROUGH TODAY/... ORGANIZED HEAVY RAIN AND LOCAL THUNDERSTORMS IS GENERALLY CONFINED TO THE NORTHEASTERN QUADRANT OF THE FORECAST AREA OF AS 1 AM. ACTIVITY OVER FOREST COUNTY IN PARTICULAR HAS BEEN VERY SLOW TO MOVE WITH MUCH REGENERATION OVER THE SAME SWATH OF THE AREA FOR THE PAST COUPLE OF HOURS. SEVERAL FLOOD RELATED WARNINGS AND ADVISORIES REMAIN IN EFFECT FOR THIS AREA THROUGH THE EARLY MORNING HOURS. OTHERWISE...AS THIS ACTIVITY SLOWLY WINDS DOWN OVER THE NEXT SEVERAL HOURS...AMPLE LOW LEVEL MOISTURE AND POOR MIXING SEEM LIKELY TO RESULT IN AREAS OF FOG WHEREVER ANY BREAKS IN THE CLOUDS MAY OCCUR. THIS WILL BE PARTICULARLY TRUE IN THE AREAS THAT SAW THE HEAVIEST RAIN TODAY FROM PITTSBURGH TO THE NORTH. FOG WAS ADDED TO THE FORECAST IN THESE AREAS. AFTER THE DEPARTURE OF EARLY MORNING RAINS...WE GENERALLY BE BE MAINLY DRY OTHER THAN A FEW ISOLATED SHOWERS UNTIL THE ARRIVAL OF THE MAIN MID-LEVEL WAVE ON FRIDAY. WILL HAVE TO TAKE A LOOK AT THIS AGAIN...BUT IT SEEMS EVERYONE WILL GET SOME SHOWERS/THUNDERSTORMS ON FRIDAY AND POPS WILL LIKELY BE RE-UPPED TO LIKELY OR HIGHER WITH THE NEXT UPDATE. LUCKILY ENOUGH...PARAMETERS DO NOT FAVOR SEVERE WEATHER WITH THIS ACTIVITY AT THIS TIME ON FRIDAY. ADDITIONALLY...DUE TO THE EASTWARD MOVEMENT OF THE UPPER FORCING...CONVECTION SEEMS MUCH LESS LIKELY TO LINGER IN THE SAME AREAS ON FRIDAY...SO FLOODING CONCERNS WILL BE REDUCED. FRIES && .SHORT TERM /TONIGHT 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 /06Z FRIDAY 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...
