AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 1043 AM EDT THU AUG 4 2005 .NEAR TERM (THIS AFTERNOON)... WEAK BACKDOOR FRONT SOMEWHERE SW OF CWA THIS AM...BUT NOT ALL THAT NOTICABLE IN TERMS OF T/TDS...ONLY A WEAK WIND SHIFT. EXPECT THE LOW LEVEL E-NE WINDS TO GET MIXED OUT AS TEMPS CLIMB INTO M-U80S IN NEXT COUPLE OF HOURS. RETURN FLOW WOULD NORMALLY SEND TDS CLIMBING AS WELL...BUT AS HAS BEEN THE CASE RECENTLY...MIXING LIKELY TO GET THE BEST OF THE HIGHER TDS. THUS...HEAT INDICES WILL BE BORERLINE AT BEST FOR THE NYC HEAT ADVISORY BUT WILL LEAVE ADVISORY UP FOR NOW...COULD STILL SEE BRIEF PERIOD RIGHT AROUND 100F HI. CONVECTIVE CHANCES FOR THIS AFTERNOON MINIMAL GIVEN ABOVE DISCUSSION...T/TD SPREADS QUITE LARGE (ESPECIALLY WITH MIXING EXPECTED THIS AFTERNOON). MODIFYING SOUNDINGS TO L-M90S/L70S WOULD PROBABLY BE ENOUGH TO GET SOMTHING STARTED. HOWEVER...WITH LACK ON CONFIDENCE ON TDS REACHING THOSE LEVELS...WILL TAKE OUT PREVIOUS 20 POP. CANT RULE OUT ISOLATED TS...BUT COVERAGE-WISE...PROBABLY NOT WORTHY OF EVEN A 20 POP BUT WILL LEAVE IN NW TO FIT IN BETTER WITH SURROUNDING WFOS. && .SHORT TERM (TONIGHT THROUGH SATURDAY)... HIGH AMPLITUDE RIDGE AXIS WORKS ACROSS THE NORTHEAST TONIGHT... ALLOWING NEXT UPPER TROUGH TO SWING INTO THE NE FOR FRIDAY. HIGH PRESSURE STRENGTHENS TO THE SE OF THE REGION...WITH WARM FRONT WORKING NE OF AREA AND WARM SW FLOW RETURNING OVER ENTIRE REGION. TEMPS ON FRIDAY WILL ONCE AGAIN ROCKET WELL INTO THE 90S ACROSS MOST OF THE AREA WITH SW-W FLOW...MIXING TO 800 HPA...AND ADJUSTED 850 HPA TEMPS OF BETWEEN 20 AND 21C. MAY NEED TO ISSUE HEAT ADVISORY FOR CITY ON FRIDAY AS DRIER AIR WILL LAG BEHIND COLD FRONT. THIS WILL BE DEPENDENT ON FRONTAL PASSAGE TIMING...BUT WITH TEMPS PROGGED INTO THE MID TO UPPER 90S AND MOISTURE POOLING AHEAD OF THE FRONT HEAT INDICES MAY RISE TO AROUND 100 ONCE AGAIN. MODELS IN FAIRLY GOOD AGREEMENT WITH TIMING AND STRENGTH OF SURFACE COLD FRONT APPROACHING FROM THE WEST TONIGHT...INTO WESTERN ZONES FRIDAY AFTERNOON...AND THEN WORKING EAST OF THE REGION BY FRIDAY NIGHT. UPPER SUPPORT REMAINS WELL TO THE NORTH WITH THIS FRONT...BUT WITH MARGINAL INSTABILITY...MOISTURE POOLING TO AROUND 2 PWATS...AND LOW-LEVEL CONVERGENCE ALONG/AHEAD OF THE FRONT WILL CONTINUE THREAT OF SCATTERED CONVECTION FROM MIDDAY FRIDAY THROUGH AROUND MIDNIGHT. THREAT OF ORGANIZED STRONG/SEVERE STORMS LOOKS POOR WITH WEAK DEEP LAYER SHEAR AND LACK OF MID/UPPER SUPPORT. UPPER TROUGH PIVOTS NE INTO SE CANADA FRIDAY NIGHT INTO SATURDAY WITH GENERALLY WESTERLY UPPER FLOW OVER THE REGION. AT THE SURFACE...THE COLD FRONT WORKS SOUTH OF THE REGION FRIDAY NIGHT WITH MODIFIED CANADIAN HIGH PRESSURE BUILDING INTO THE REGION FOR SATURDAY. THIS WILL PROVIDE FAIR AND DRY WEATHER WITH A NOTICEABLY COOLER AND DRIER AIR AIRMASS TO START THE WEEKEND. && .LONG TERM (SUNDAY THROUGH WEDNESDAY)... NO MAJOR CHANGES TO EXTENDED. THE OVERALL PATTERN FEATURES A MEAN TROUGH OVER THE NORTHEAST FOR THE BEGINNING OF THE PERIOD. THE UPPER FLOW TRANSITIONS BACK TO MORE OF AN FAST WESTERLY FLOW BY SUN...AND WE/LL REMAIN ON THE SOUTHERN EDGE OF THE NORTHERN BRANCH. THIS IS WHERE THE MREF MEMBERS BEGIN DIVERGING...HOWEVER MOST OF THEM GRADUALLY DEVELOP A BROAD TROUGH OVER THE NORTHEASTERN PART OF THE COUNTRY BY WED. AT THE SFC...OLD FRONTAL BOUNDARY STALLS OUT THROUGH THE MID ATLANTIC REGION ON SAT AND EVENTUALLY DISSIPATES ON SUN. HIGH PRES BUILDS INTO THE NORTHEAST DOMINATING THROUGH THE REMAINDER OF THE FORECAST PERIOD..WITH JUST THE CHANCE OF DIURNAL CONVECTION FROM MONDAY ON. TEMPS WILL MODERATE BACK TO SEASONABLE LEVELS SUN...WITH A GRADUAL INCREASE IN HEAT AND HUMIDITY AS THE WEEK PROGRESSES. && .MARINE... RELATIVELY TRANQUIL WIND AND SEA CONDS WILL REMAIN OVER THE WATERS FOR MOST OF THE FORECAST PERIOD DUE TO A WEAK PRESSURE PATTERN OVERHEAD. HOWEVER...THE PRESSURE GRADIENT DOES TIGHTEN OVER THE WATERS LATER THURS NITE THRU FRI EVENING AS A COLD FRONT APPROACHES THEN CROSSES THE WATERS. WE COULD SEE SEAS AND WINDS ON THE OCEAN APPROACH SCA CRITERIA ON FRIDAY AS A RESULT. FOR NOW WILL DO WITHOUT ANY HEADLINES SINCE THIS WILL BE A MARGINAL EVENT. && .AVIATION... VFR CONDS EXPECTED THRU THIS EVENING. && .CLIMATE... RECORDS SEEM A BIT OUT OF REACH TODAY WITH AN ONSHORE COMPONENT TO FLOW. RECORD HIGH TEMPERATURES FOR AUGUST 4 ARE AS FOLLOWS: EWR - 100 (1993) LGA - 96 (1995) NYC - 100 (1944) ISP - 91 (1989) JFK - 93 (1995) && .HYDROLOGY... NEXT CHANCE OF MEASURABLE RAINFALL FRIDAY AFT/EVE. GENERALLY AROUND 0.10 RAINFALL EXPECTED...BUT WITH JUICIER AIRMASS...LOCALLY HIGHER AMOUNTS IN CONVECTION QUITE LIKELY. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...HEAT ADVISORY FOR NYC BOROUGHS...NYZ072>076. NJ...NONE. MARINE...NONE. && SHORT TERM: SR/BC LONG TERM: JST
