AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 300 PM EDT SAT JUN 11 2005 .SHORT TERM... SCATTERED CONVECTION DEVELOPING ACROSS MAINLY NORTHEAST PA THIS AFTN WHERE REMNANTS OF OUTFLOW BOUNDARIES FROM YESTERDAYS STORMS LIKELY TO BE ALONG WITH TERRAIN EFFECTS. THE STORMS ARE PRODUCING HEAVY RAIN BUT ARE NOT ABLE TO BUILD MUCH, WITH RADAR SHOWING OTHER CELLS IN THE FORECAST AREA STARTING TO GENERATE BUT ALMOST AS QUICKLY DYING OUT. REALLY NOT A TRIGGER TO AID IN DEVELOPMENT AND THERE APPEARS TO BE SOME CAP ACROSS THE AREA INHIBITING STORMS FROM GETTING GOING EXCEPT FOR THE RIDGE LINES ACROSS THE POCONOS. WILL BE INTERESTING TO SEE IF THIS CAN BE BROKEN AS THE AFTERNOON WEARS ON. STILL PLAN ON CARRYING CHC OR SCT TSRA INTO THIS EVENING ACROSS THE ENTIRE FORECAST AREA. THERE WILL NOT BE MUCH CHANGE TO THE OVERALL SYNOPTIC WEATHER PATTERN THROUGH THE SHORT TERM PERIOD OF THE FORECAST AS THE AREA WILL REMAIN UNDER THE INFLUENCE OF LARGE UPPER RIDGE AND BERMUDA HIGH OFF THE EAST COAST. THE CONTINUATION OF THE VERY WARM AND HUMID CONDITIONS WILL COMBINE WITH LEFT OVER OUTFLOW BOUNDARIES, TERRAIN, AND OCCASIONAL WEAK UPPER DISTURBANCES TO PRODUCE SCATTERED SHOWER AND THUNDERSTORM ACTIVITY MAINLY DURING THE HEATING OF THE DAY...FROM LATE MORNING THROUGH THE MID EVENING HOURS. IT LOOKS LIKE SUNDAY MAY SEE A LITTLE BETTER S/W TO PASS THROUGH THE AREA WHICH WILL LIKELY GIVE US BETTER COVERAGE THAN WHAT WE ARE SEEING TODAY. WEAK WIND FIELDS FROM SFC TO 500MB AND PRECIP WATER VALUES AROUND 200% ABOVE NORMAL WILL SPELL A CONTINUED THREAT FOR TORRENTIAL DOWNPOURS WITH ANY THUNDERSTORMS THAT DEVELOP OVER THE NEXT COUPLE OF DAYS. AREAS THAT SAW HEAVY RAIN YESTERDAY AND TODAY WILL SEE AN ENHANCED THREAT. THE REMNANTS OF T.S. ARLENE WILL MOVE NORTHWARD AND INTERACT WITH A FRONTAL BOUNDARY IN THE MIDWEST. IT APPEARS THAT THE SYSTEM WILL BE STEERED BY THE WESTERN ATLANTIC RIDGE AND THE STRENGTH OF THE RIDGE WILL KEEP THE SYSTEM WELL WEST AS SHOWN BY TPC/NHC GUIDANCE. THE GFS TRACKS THE LOW FURTHER EAST AND INTO WESTERN NYS ON MONDAY. FOR NOW, WILL CONTINUE TO FOLLOW THE FURTHER WEST SOLUTIONS, BUT STILL CHC FOR TSRA ON MONDAY ANYWAY WITH THE CONTINUED CURRENT WEATHER REGIME. && .LONG TERM (MON NITE - SAT)... MUCH OF THE SAME TRIPLE H WEATHER CONTINUES EARLY IN THE LONG RANGE PERIOD...THEN MANY MED RANGE MODELS AND ENSEMBLES ARE LOCKING ONTO THE GENERAL CONSENSUS OF SIGNALING A SIGNIFICANT PATTERN CHANGE WHERE BERMUDA HIGH OVER EAST COAST RETREATS...AND IS REPLACED BY AN OMEGA BLOCK WITH TROFS ON BOTH COASTS OF THE CONTINENTAL US. LOCALLY WELL BE LOOKING FOR THE HOT AND HAZY WEATHER OF LATE TO LINGER INTO TUESDAY WITH SCT THUNDERSTORMS AS IMPULSES ROUND THE RIDGE...AND ALSO REMNANTS OF TROPICAL STORM PASS THROUGH OR NEARBY THE REGION. WL GO ABOVE MOS NUMBERS INTO TUESDAY WITH PROGGED 850 MB TEMPS OF 17-18C STILL SUPPORTING MID-UPR 80S...THEN AIRMASS COOLS BACK TO 8-9C BY THE END OF THE WEEK UNDER DVLPG UPR TROF. LOOK FOR MAX TEMPS TO GET BACK INTO THE 60S-70S. MOS IS ACCEPTABLE HERE DAYS 5-7. NOT MUCH ROOM FOR DRY WX NEXT WEEK WITH HGHT FALLS AHEAD OF DIGGING UPR LOW AND FRONT DROPPING THRU THE REGION.
