Area forecast discussion, Jun 13, 8:22 PM EDT, 4 hours 57 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 822 PM EDT SAT JUN 13 2009 .SYNOPSIS... AN UPPER AIR DISTURBANCE THAT CROSSED THE REGION THIS EVENING WILL MOVE EAST OF THE AREA OVERNIGHT. WEAK HIGH PRESSURE WILL BUILD OVER THE REGION SUNDAY. ANOTHER DISTURBANCE WILL APPROACH SUNDAY NIGHT AND BRING UNSETTLED WEATHER FOR THE BEGINNING OF THE WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... WE CONTINUED TO HAVE TSTMS NORTH AND ISOLATED TSTMS SW. HOWEVER, MORE STABLE AIR WAS SPREADING IN FROM THE EAST WITH THE SOUTHERN AREAS GETTING THIS FIRST. THEREFORE, THE ACTIVITY NORTH SHOULD CONTINUE FOR A FEW MORE HRS WHILE THE TSTMS S WILL LESSEN. SINCE WE STILL HAVE MOISTURE A GOOD PORTION OF THE NIGHT, THE POSSIBILITY OF SHOWERS HAVE BEEN KEPT IN THROUGH THE NIGHT ALTHOUGH TSTMS HAVE BEEN DROPPED AFTER MIDNIGHT. WITH SO MUCH MOISTURE OVER THE REGION, PATCHY FOG WAS KEPT IN THE FCST OVERNIGHT. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... IT IS STILL LOOKING LIKE THE FIRST RATER DRY DAY FOR OUR AREA WILL BE SUNDAY WITH A WEAKENING HIGH PRESSURE AREA DRIFTING IN FROM THE GREAT LAKES REGION DURING THE DAY. WHILE SFC WINDS WILL BE LIGHT, THE WINDS OFF THE DECK WILL TURN TO N OR NW AND THIS WILL BRING SOME DRIER AIR TO THE REGION. TEMPERATURES WILL BE IN THE UPPER 70S TO LOW 80S IN MOST AREAS, COOLER IN THE SOUTHERN POCONOS. ANOTHER VORT MAX IN THE NW FLOW WILL ROLL TOWARD OUR REGION SUNDAY NIGHT THROUGH MONDAY. THE GFS/ECMWF MODELS ARE STILL DRY FOR SUN NIGHT ACROSS THE AREA WHILE THE NAM IS OFFERING SOME LIGHT QPF. I HAVE KEPT THE FCST DRY FOR NOW WITH ONLY SLGT CHC POPS NORTH AND WEST. A BETTER CHC FOR SHOWERS AND THUNDER WILL BE ACROSS THE AREA MONDAY WITH THE BEST DYNAMICS AND SOME LIMITED CAPE VALUES OVER THE REGION. && .LONG TERM /TUESDAY THROUGH SATURDAY/... MOSTLY FAIR WEATHER WILL BE OVER THE REGION DURING THE BEGINNING OF THE EXTENDED PERIOD AS HIGH PRESSURE WILL BE OFF TO THE NORTHEAST AND AN UPPER RIDGE WILL BE APPROACHING FROM THE WEST. A SLIGHT CHC OF SHOWERS WILL STILL BE KEPT IN THE GRIDS FOR NOW, AS THIS WORKS BEST WITH OUR SURROUNDING OFFICES. THE SYSTEM EXITING AT THE END OF THE SHORT TERM PERIOD MAY LINGER INTO EARLY TUESDAY. AFTER A PERIOD OF FAIR WEATHER WEDNESDAY, THE NEXT UPPER TROUGH WILL APPROACH AND DEEPEN ACROSS OUR AREA. MODELS ARE SHOWING THE POSSIBILITY OF SHOWERS AND THUNDER IN NW FLOW OVER OUR AREA SO SLIGHT CHC POPS WED NIGHT WILL REMAIN AND CHC POPS WILL FILL OUT MOST OF THE REST OF THE EXTENDED PERIODS FOR NOW. TEMPERATURES DURING THE EXTENDED PERIOD WILL IN GENERAL BE BELOW NORMAL WITH DAYTIME HIGH TEMPERATURES IN THE MID TO UPPER 70S IN MOST AREAS. SOME LOW 80S ARE IN THE GRIDS FOR FRI AND SAT NEXT WEEKEND, WELL SEE. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. THIS SET OF TAFS WE JUST ISSUED FOLLOWS THE IDEA OF THE LATEST WRF-NMM MODEL WHICH KEEPS THE INSTABILITY GOING IN CENTRAL PA AND PROPAGATES THE SHOWERS AND THUNDERSTORMS EASTWARD, BUT DISSIPATES AND WEAKENS THEM IN THE MARINE AIR OVER OUR TERMINAL AREA. THUS THE LONGEST DURATION TEMPO GROUPS ARE FOR KRDG AND KABE AND LESS TIME AND THEN NO THUNDER (FOR KACY AND KMIV) FOR PLACES FARTHER TO THE EAST. THERE WAS STRATUS ADVECTING OFF THE COAST PRIOR TO SUNSET, BUT WITH HIGHER CLOUDS ABOVE IT, ITS IMPOSSIBLE TO NOW FOLLOW. WE BELIEVE THE COMBINATION OF THE HEAVY RAIN AND MOISTURE FROM THE ONSHORE FLOW WOULD STILL MAKE LIKELY THAT IFR CONDITIONS DEVELOP TOWARD DAYBREAK. RIGHT NOW WE ARE EXPECTING A BETTER DAY FOR SUNDAY WITH VFR CONDITIONS DEVELOPING BY EARLY AFTERNOON. OUTLOOK... HIGH PRESSURE PUSHING IN FROM THE NW WILL BRING SLIGHTLY DRIER AIR AND VFR WEATHER SUNDAY NIGHT INTO MONDAY, ALTHOUGH THERE COULD BE ADDITIONAL SHOWERS/TSTMS MONDAY AFTERNOON INTO MONDAY NIGHT AS ANOTHER FRONTAL ZONE CROSSES OUR AREA. ANOTHER HIGH PRESSURE THEN FORECAST TO REBUILD INTO THE AREA WILL BRING GENERALLY FAIR VFR WEATHER TUESDAY THROUGH WEDNESDAY. A WARM FRONT COULD CAUSE A DOWNTURN IN FLYING CONDITIONS AGAIN FOR THE END OF THE WEEK. && .MARINE... CONDITIONS CONTINUE BELOW SMALL CRAFT ADVISORY CRITERIA AND SHOULD REMAIN SO AT LEAST THROUGH MONDAY NIGHT, DESPITE A PERSISTENT ONSHORE FLOW. THIS FLOW SHOULD BE LIGHT ENOUGH TO PRECLUDE 5 FOOT SEAS. WAVEWATCH DOES EVENTUALLY BUILD SEAS TO 5 FEET AND HIGHER LATE TUESDAY OR TUESDAY NIGHT AS WINDS VEER TO THE SOUTHEAST AND SOUTH. THIS COULD BE OVERDONE, SINCE THE GFS DEVELOPS A LOW TO OUR SOUTH AND MOVES IT EAST. IT INTERACTS WITH STRONG HIGH PRESSURE TO OUR NORTH, WHICH CAUSES A TIGHTENED PRESSURE GRADIENT. OTHER COMPUTER MODELS KEEP THE LOW MUCH WEAKER AND FARTHER SOUTH AND KEEP US UNDER THE INFLUENCE OF THE HIGH TO OUR NORTH. WE WILL CONTINUE TO MONITOR AND, HOPEFULLY, THE MODELS WILL HONE IN ON A SOLUTION AS THIS WEEKS WEATHER UNFOLDS. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
