AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY 728 PM EDT SUN JUL 7 2013 .SYNOPSIS... A FRONTAL BOUNDARY APPROACHES FROM THE NORTH AS AN UPPER LEVEL DISTURBANCE MOVES OVER THE AREA MONDAY. A COLD FRONT APPROACHES FROM THE WEST AND WILL IMPACT THE AREA THROUGH THE WEEKEND. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... SEVERE THUNDERSTORM WATCH CONTINUES THROUGH 02Z FOR NE NJ AND THE LOWER HUDSON VALLEY. THE LINE OF STORMS IS STARTING TO EXTEND NORTH WITH ISOLATED CELLS BUT NONE ARE SEVERE AT THIS TIME. HIGH CAPE IS STILL PRESENT IN THE AREA AND STORMS ARE OF THE PULSE NATURE SO ANY CAN GO SEVERE AT ANY TIME...ESPECIALLY WITH OUTFLOW BOUNDARIES AND RESIDUAL SEA BREEZE BOUNDARIES PRESENT. ALSO MONITORING THE SOUTHERN PART OF THE LINE WITH HAS STRENGTHENED IN THE PAST HOUR. WITH THE LOSS OF DAYTIME HEATING...THERE IS A GOOD CHANCE THIS LINE WILL NOT BE SEVERE ONCE IT MAKES IT TO THE CWA BUT IT WILL HAVE TO CONTINUE TO BE MONITORED. OTHERWISE...A WARM AND MUGGY NIGHT IS IN STORE. RIDGE BEGINS TO WEAKEN AS TROUGH APPROACHES FROM THE WEST. WITHOUT ANY REAL CHANGE IN AIRMASS THOUGH...THE HEAT IN BE TRAPPED...AND WIDESPREAD LOW TEMPS IN THE 70S IS EXPECTED...NEAR 80 ACROSS PORTIONS OF NEW YORK CITY COURTESY OF HEAT ISLAND EFFECTS. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... APPROACHING BUT WEAKENING TROUGH MOVES ACROSS THE AREA MONDAY. MODELS IN REASONABLE AGREEMENT HANDLING OF THIS TROUGH. WITH PLENTY OF LOW LEVEL/BOUNDARY LAYER WARM AIR IN PLACE...MODERATE INSTABILITY IS EXPECTED. HOWEVER...LAPSE RATES NOT TOO IMPRESSIVE...LESS THAN 6C/KM...AND SHEAR IS WEAK. HOWEVER...COVERAGE OF SHOWERS AND THUNDERSTORMS SHOULD REMAIN FAIRLY HIGH...ALTHOUGH NOT QUITE TO THE NUMEROUS OR LIKELY THRESHOLDS ON POPS PER MODELS/STATISTICAL GUIDANCE. THE TROUGH/ASSOCIATED VORTICITY ADVECTION MOVES SLOWLY TO THE EAST MONDAY NIGHT...AND WOULD EXPECT SCATTERED SHOWERS/TSTMS TO DIMINISH IN COVERAGE AND INTENSITY AS THE NIGHT PROGRESSES. AT THE SFC...HIGH PRESSURE GETS FURTHER SUPPRESSED TO THE SOUTH AS A FRONTAL BOUNDARY/WEAK LOW APPROACHES BUT REMAINS TO THE NORTH THIS TIME FRAME. ANOTHER WARM TO HOT DAY IS EXPECTED...ALTHOUGH NOT NEARLY TO THE EXTENT AS WE HAVE EXPERIENCED OVER THE PAST COUPLE OF DAYS. DO NOT FORESEE ANY HEAT RELATED HEADLINES WITH HEAT INDICES AROUND 90 OR IN THE LOWER 90S AWAY FROM THE SHORE. WILL LEAN TOWARD A MOS BLEND FOR TEMPS/DEW POINTS. HIGHS MONDAY WILL GENERALLY BE IN THE UPPER 80S TO NEAR 90 AWAY FROM SOUTH FACING SHORES...AND LOWS AT NIGHT WILL BE SLIGHTLY COOLER...IN THE UPPER 60S TO LOWER 70S. && .LONG TERM /TUESDAY THROUGH SUNDAY/... LONG TERM STARTS OUT WITH A SHORTWAVE PASSING TO OUR EAST BY TUESDAY MORNING AND MAINLY ZONAL FLOW BRIEFLY SETTLING IN ACROSS THE AREA. USED A MAV/MET BLEND FOR HIGHS...BROUGHT DOWN TEMPS A DEGREE OR MORE IN SOME AREAS BECAUSE WE HAVE BEEN RUNNING AT THE WARMEST OF GUIDANCE FOR THE HIGH TEMP. TEMPS WILL DEPEND ON HOW MUCH CLOUD COVER STICKS AROUND BEHIND THE SHORTWAVE. IF WE GET MORE CLEARING...TEMPS COULD BE A COUPLE DEG WARMER. ON WEDNESDAY...A TROUGH WILL APPROACH FROM THE MIDWEST WITH A SURFACE LOW DEVELOPING SOMEWHERE NEAR MICHIGAN OR JUST NORTH WITH DISCREPANCIES AMONG THE EXACT PLACEMENT. AN AFTERNOON SURFACE TROUGH WILL LIKELY DEVELOP WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. HIGHEST CHANCES WILL BE NORTH AND WEST OF NYC BUT CANNOT RULE OUT MORE WIDESPREAD SHOWERS MAKING TO TO THE EASTERN PARTS OF THE CWA. SIMILAR TEMPERATURES VALUES TO TUESDAY FOR WEDNESDAY...MAYBE JUST A TOUCH COOLER. COULD SEE SOME GUSTY WINDS BEGINNING ON WED AS WELL AS A LOW LEVEL JET DEVELOPS AHEAD OF A COLD FRONT. A COLD FRONT EXTENDING FROM THE PREVIOUSLY MENTIONED LOW WILL THEN APPROACH ON THURSDAY AND THROUGH FRIDAY. WITH IT BEING A FEW DAYS OUT...CANNOT PINPOINT THE EXACT TIMING OF THE PASSAGE OF THE FRONT BUT IT SHOULD BE SOMETIME THURSDAY EVENING TO FRIDAY MORNING. THIS WILL BRING SHOWERS AND THUNDERSTORMS TO THE AREA FROM THURSDAY MORNING THROUGH FRIDAY AFTERNOON. SHEAR IS NOT OVERLY IMPRESSIVE FOR THURSDAY BUT WITH DECENT LIFT AND PLENTY OF AFTERNOON INSTABILITY...WOULD NOT BE SURPRISED TO SEE SOME STRONGER THUNDERSTORMS DEVELOP. THE TEMPS WILL CONTINUE TO COOL WITH FRIDAY HIGHS DROPPING INTO THE LOWER TO MIDDLE 80S. ON FRIDAY THE COLD FRONT ACTUALLY SEEMS TO STALL JUST EAST OF THE AREA AND THEN RETROGRADE BACK WEST AS AN UPPER LOW BECOMES CUT OFF OVER THE SOUTHEASTERN U.S. THIS WILL KEEP A CHANCE OF SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGH THE DAY AND INTO SUNDAY AS THE FRONT MOVES WEST AND DISSIPATES. WEEKEND HIGH TEMPS WILL BE JUST AT OR BELOW NORMAL. LOW TEMPERATURES THROUGH THE LONG TERM WILL BE JUST ABOVE NORMAL. EXPECT MOSTLY CLOUDY TO CLOUDY SKIES THROUGH THE WEEK WITH MAYBE SOME CLEARING EACH MORNING. GENERALLY SW-W WINDS THROUGH THE LONG TERM OUTSIDE OF THE WED-FRI TIME FRAME WITH THE LOW LEVEL JET DEVELOPING. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... A WEAK SFC TROF WILL REMAIN INVOF THE HUDSON RIVER THRU THE TAF PERIOD. MAINLY VFR THRU THE TAF PERIOD. SCT TSTMS NEAR THE CITY AND WESTERN TERMINALS WILL CONTINUE TO WEAKEN AND SHOULD NO LONGER BE A THREAT AFTER 03Z. FOR MONDAY...SW-WSW WINDS INCREASING TO 10-15KT AFTER THE MORNING PUSH. AFTERNOON GUSTS AT KEWR/KTEB/KLGA AGAIN...UP TO AROUND 20KT. SCT SHRA/TSTMS EXPECTED IN THE AFTERNOON. .OUTLOOK FOR 00Z MONDAY THROUGH FRI... .MON NIGHT-FRI...MAINLY VFR...BUT SUB-VFR POSSIBLE IN SCT TSTMS THRU THE ENTIRE PERIOD. && .MARINE... HIGH PRESSURE DRIFTS FURTHER SOUTH AS A FRONTAL BOUNDARY AND WEAK LOW PRESSURE REMAINS TO THE NORTH THROUGH MONDAY. GENERAL SW WINDS EXPECTED...WITH SUB SCA CRITERIA THROUGH MONDAY AND MONDAY NIGHT. WINDS MAY INCREASE SLIGHTLY DURING THE DAYTIME LOCALLY DUE TO ENHANCEMENT FROM SEA BREEZES. WINDS AND WAVES WILL REMAIN BELOW SCA CRITERIA TUESDAY THROUGH THURSDAY. A COLD FRONT WILL THEN APPROACH THE WATERS WITH A LOW LEVEL JET DEVELOPING. SEAS WILL BE ON THE INCREASE AND OCEAN SEAS COULD BE ABOVE 5 FT BUT THURSDAY MORNING AND REMAIN ELEVATED THROUGH FRIDAY. WINDS WILL ALSO BE AT MARGINAL SCA CRITERIA BEGINNING THURSDAY MORNING AND CONTINUING THROUGH FRIDAY. && .HYDROLOGY... SCATTERED SHOWERS/THUNDERSTORMS WILL PRODUCE LOCALLY HEAVY RAIN THIS EVENING AND AGAIN ON MONDAY. THE PROBABILITY FOR WIDESPREAD HEAVY RAIN INTO THE MIDDLE OF NEXT WEEK IS LOW. HOWEVER...ANY TSTMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE.
