A powerful cold front triggered numerous severe thunderstorms from Staten Island eastward across Long Island.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New York, NY wrote its last area forecast discussion before the first event at Jul 27, 6:45 AM EST, 2 hours 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 745 AM EDT SUN JUL 27 2008 .SYNOPSIS... A TROUGH IN THE LEE OF THE APPALACHIANS WILL REMAIN NEARLY STATIONARY OVER WESTERN PARTS OF THE TRI-STATE THROUGH MONDAY MORNING...WHEN IT WILL MERGE WITH A COLD FRONT APPROACHING FROM THE WEST...WHICH WILL CROSS THE REGION MONDAY AFTERNOON AND EVENING. WEAK HIGH PRESSURE THEN BUILDS IN LATE MONDAY NIGHT AND TUESDAY...THEN SLIDES OFFSHORE TUESDAY NIGHT. AN AREA OF LOW PRESSURE WILL TRACK EAST ACROSS THE AREA WEDNESDAY AND WEDNESDAY NIGHT. A FRONT WILL THEN REMAIN STALLED JUST SOUTH OF THE REGION WITH WAVES OF LOW PRESSURE PERIODICALLY RIDING ALONG THE FRONT FOR THE REMAINDER OF THE WEEK. && .NEAR TERM /THROUGH TONIGHT/... HAVE UPDATED TO BRING ALL AREAS UP TO CHANCE POPS THIS MORNING...AS LINES OF CONVECTION HAVE HELD TOGETHER BETTER THAN EXPECTED SO FAR THIS MORNING. WINDS HAVE PEAKED OUT AT 25KT WITH ONLY LIGHT RAINFALL AMOUNTS WHERE THE STORMS HAVE CROSSED ASOS SITES...SO DO NOT EXPECT ANYTHING SIGNIFICANT OUT OF CURRENT BATCH OF STORMS. HOWEVER...WHAT THIS HAS SHONE IS ATMOSPHERE IS ALREADY UNSTABLE ENOUGH TO SUPPORT THUNDERSTORMS...WITHOUT THE BENEFIT OF ANY SOLAR HEATING...SO GIVES VALIDITY TO CURRENT THINKING OF A SEVERE THREAT FOR LATER TODAY. PREVIOUS DISCUSSION FOLLOWS... WHILE GFS HAS BETTER OVERALL HANDLE ON CURRENT CONVECTION COMPARED TO NAM...IT DOES HAVE CONVECTIVE FEEDBACK ISSUES...SO DO NOT TRUST IT COMPLETELY. BOTH MODELS ARE UNDER DOING AMOUNT OF LOW LEVEL MOISTURE...SO LOOKED MORE AT FORCING DEPICTED BY BOTH MODELS AND BLENDED THIS TO COME UP WITH AN OVERALL FORECAST. STILL APPEAR ON TRACK FOR STRONG TO SEVERE THUNDERSTORMS TODAY AND TONIGHT...WITH THE BEST CHANCE LATE THIS AFTERNOON (WEST) AND EARLY THIS EVENING (EAST) SO HAVE LIKELY POPS THEN. FOR THIS MORNING HAVE CHANCE POPS INCREASING FROM NW TO SE...AND GRADUALLY TAPER POPS DOWN FROM NW TO SE AFTER MIDNIGHT TONIGHT. AS FOR THE SEVERE THREAT...RUC SUPPORTS GFS IDEA OF 3000 PLUS J/KG OF CAPE OVER THE LOWER HUDSON VALLEY/NE NJ/SW CT BY 18Z THIS AFTERNOON (NAM HAS LOWER VALUES BUT SIMILARLY PLACED). BOTH NAM AND GFS THEN INCREASE CAPE OVER EASTERN AREAS TO AROUND 2000 J/KG IN EARLY EVENING...THEN GRADUALLY DIMINISH FROM NW TO SE AS THE NIGHT PROGRESSES. SHOULD HAVE ABUNDANT LOW LEVEL MOISTURE TO WORK WITH NOTING PROGGED IN LOW LEVEL THETA-E RIDGE OF 344-348K. IN ADDITION TO GOOD THERMO DYNAMICS...ALSO HAVE PRETTY POTENT 5H SHORTWAVE PROGGED ACROSS THE AREA THIS AFTERNOON AND EVENING...AS WELL AS THE REGION ENDING UP IN THE RIGHT ENTRANCE REGION OF A 60KT UPPER JET STREAK. IT APPEARS WILL HAVE 25-35KT OF GENERALLY UNIDIRECTIONAL SHEAR...SUGGESTING POTENTIAL FOR LINE SEGMENTS AND POSSIBLE CLUSTERS FORMING OUT AHEAD OF THE SEGMENTS (SUCH AS IS GOING ON OVERNIGHT). THE MAIN THREAT IS DAMAGING WINDS..ESPECIALLY NEAR THE APEX OF ANY BOW ECHO...AND LARGE HAIL. ACCORDINGLY SPC HAS THE ENTIRE CWA UNDER A SLIGHT RISK FOR SEVERE THUNDERSTORMS. FOR TEMPERATURES...FOR HIGHS TODAY USED A BLEND OF MAV/FWC MOS WITH MIX DOWN OF NAM 850 TEMPERATURE (WEIGHED MORE TOWARDS MIXED DOWN TEMPERATURE INLAND...AND MOS NEAR THE COAST)...FOR LOWS TONIGHT USED A MAV/FWC/MET BLEND. TEMPERATURES SHOULD RUN SLIGHTLY ABOVE NORMAL. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... WITH SURFACE TO 850 COLD FRONT MOVING THROUGH MONDAY AFTERNOON/EVENING ALONG WITH MID TO UPPER LEVEL TROUGH AXIS...HAVE MAINTAINED CHANCE POPS THAT TIME FRAME (HIGHER THAN GUIDANCE...BUT NOT MUCH ABOVE A BLEND OF FWC/MET 6 HOUR POPS). APPEARS MODELS UNDERESTIMATING LOW LEVEL MOISTURE (AS THEY CURRENTLY ARE) AS DRIER AIR WILL NOT MOVE IN UNTIL PASSAGE OF MERGED COLD FRONT/LEE TROUGH COMBO (IT APPEARS MODELS TRY TO ADVECT DRIER AIR BETWEEN LEE TROUGH AND COLD FRONT CURRENTLY THROUGH THE LEE TROUGH OVERNIGHT...HOWEVER EXPERIENCE SUGGESTS APPALACHIANS WILL ACT AS SUFFICIENT BARRIER TO PREVENT THAT FROM HAPPENING. WILL HAVE LESS SHEAR MONDAY THAN TODAY...SO THREAT OF SEVERE WEATHER IS REDUCED AS WELL. LOOKS LIKE MONDAY WILL BE ABOUT A DEGREE OR SO WARMER THAN TODAY (WARM PUSH AHEAD OF COLD FRONT). LOWS MONDAY NIGHT SHOULD BE A TAD COOLER THAN TONIGHT BEHIND THE FRONT. MAIN IMPACT OF COLD FRONT WILL BE TO DRY THINGS OUT SOMEWHAT...SO HAVE GONE WITH A DRY FORECAST FROM LATE MONDAY EVENING THROUGH TUESDAY NIGHT (RETURN FLOW JUST SETTING UP TUESDAY NIGHT...SO TO SOON TO SUPPORT DIURNAL CONVECTION). IMPACT OF COLD FRONT IS NOT ALL THAT SIGNIFICANT AS FAR AS HIGHS GO AS VERY WELL COULD APPROACH/REACH 90 IN METRO NEW YORK CITY HEAT ISLAND (AWAY FROM SOUTHERN COASTAL AREAS) AGAIN ON TUESDAY...AND WITH A UNIFORM WESTERLY FLOW THROUGH THE BOUNDARY LAYER...THE SEA BREEZE WILL NOT BE FROM TYPICAL ONSHORE DIRECTION...BUT MORE SW (IF IT FORMS AT ALL)...SO TUESDAY COULD BE THE WARMEST DAY SO FAR THIS WEEK FOR COASTAL AREAS. LOWS TUESDAY NIGHT WILL RUN A FEW DEGREES ABOVE NORMAL. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... FOR EXTENDED LEANED TOWARDS A BLEND OF 00Z GEFS MEAN AND 12Z AND 00Z ECMWF. A STORM SYSTEM WILL CROSS THE TRI-STATE WEDNESDAY/WEDNESDAY NIGHT...LIKELY PUSHING THE FRONTAL BOUNDARY THAT STALLED TO OUR SOUTH TUESDAY BACK NORTH THROUGH MOST OF THE AREA AHEAD OF IT...THEN SEND IT BACK TO OUR SOUTH BEHIND IT BY THURSDAY MORNING. BEING IN THE WARM SECTOR WEDNESDAY WILL ALLOW FOR HIGHS WEDNESDAY TO REACH NEAR TO SLIGHTLY ABOVE NORMAL LEVELS. THIS FRONT WILL REMAIN STALLED TO OUR SOUTH INTO SATURDAY WITH WAVES OF LOW PRESSURE RIDING ALONG IT FROM TIME TO TIME. THIS COUPLED WITH EASTERLY FLOW SETTING UP ACROSS THE REGION...RESULTED IN TWEAKING THE FORECAST IN A MORE PESSIMISTIC DIRECTION...WITH AT LEAST SLIGHT CHANCE POPS EVERYDAY...INCREASED CLOUD COVER AND SLIGHTLY LOWER TEMPERATURES AT DAY/SLIGHTLY WARMER AT NIGHT THAN PREVIOUS FORECAST. (SO EXPECT BELOW NORMAL HIGHS AND ABOVE NORMAL LOWS THU- SAT). && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... A BAND OF SHOWERS AND THUNDERSTORMS WILL PUSH ACROSS EASTERN PORTIONS OF THE FORECAST AREA EARLY THIS MORNING. EXPECT THE IMPACT TO BE A BRIEF BURST OF MODERATE TO HEAVY RAIN LOWERING VSBY TO IFR...CLOUD TO SURFACE LIGHTNING AND EITHER LOW END VFR OR HIGH END MVFR CIGS. THEREAFTER...EXPECT THE ATMOSPHERE TO BECOME QUIET THROUGH THE REMAINDER OF THE MORNING...AS IT RELOADS FOR THIS AFTERNOON AND THIS EVENING. A PRE FRONTAL TROUGH REMAINS JUST WEST OF THE CITY...AND A COLD FRONT WILL APPROACH AS THE DAY PROGRESSES. EXPECT THE DEVELOPMENT OF STORMS TO HOLD OFF UNTIL AFTER 17Z FROM THE NYC TERMINALS AND NORTH AND WEST. WITH UNCERTAIN TIMING AND CHANCES AT THE TERMINALS HAVE ONLY INDICATED CB GROUPS AT THIS TIME. FARTHER EAST ACTIVITY WILL BE LATER AND MORE UNCERTAIN SO LEFT OUT AT THIS TIME. THE ATMOSPHERE WILL BECOME MODERATELY TO QUITE UNSTABLE THIS AFTERNOON AND REMAIN THAT WAY THROUGH TONIGHT. THERE IS A GOOD CHANCE FOR SCT CONVECTION ACROSS MUCH OF THE FORECAST AREA THIS AFTERNOON AND EVENING. THIS WILL LIKELY IMPACT ALL BUT EASTERN TERMINALS...AND CERTAINLY WILL IMPACT APPROACH AND DEPARTURE ROUTES. MOST LIKELY TIMING FOR CONVECTIVE ACTIVITY WILL BE FROM 18Z THIS AFTERNOON THROUGH 04-06Z MONDAY. THE PEAK OF INTENSITY AND COVERAGE SHOULD BE 22Z-02Z MON. OUTLOOK FOR 12Z MONDAY THROUGH THURSDAY...ANOTHER TROUGH/COLD FRONT APPROACHES FOR MONDAY. LOCAL MVFR TO IFR CIGS/VSBYS AND GUSTY WINDS IN SHOWERS/TSTMS POSSIBLE ONCE AGAIN MONDAY AFTERNOON INTO MONDAY NIGHT. THE BOUNDARY STALLS SOUTH OF THE AREA MONDAY NIGHT. SUB-VFR CONDITIONS POSSIBLE ON WED AFTERNOON THROUGH THU AS AN AREA OF LOW PRESSURE MOVES ALONG THE STATIONARY BOUNDARY. && .MARINE... GENERALLY QUIET CONDITIONS THROUGH THE FORECAST PERIOD...WITH WINDS AND SEAS EXPECTED TO REMAIN BELOW SCA. A WEAK COLD FRONT WILL APPROACH TODAY AND WASH OUT AS IT GETS HUNG UP EITHER ACROSS WESTERN WATERS OR TO THE WEST. ANOTHER WEAK COLD FRONT WILL PUSH TOWARD THE AREA...AND IS EXPECTED TO CROSS THE WATERS MONDAY NIGHT. WEAK HIGH PRESSURE BUILDS IN FOR TUESDAY...BEFORE A ANOTHER WEAK TROUGH APPROACHES FOR THE MIDDLE OF THE WEEK. HIGH PRESSURE RETURNS FOR THE END FOR THE WEEK. A 3 FT SOUTHERLY SWELL GENERATED BY THE PRE-FRONTAL S-SW FLOW SHOULD BE ENOUGH TO CONTINUE A MODERATE RIP CURRENT RISK AT THE OCEAN BEACHES TODAY. && .HYDROLOGY... EVEN WITH SHOWERS AND THUNDERSTORMS TODAY AND TONIGHT...SHOULD BE RELATIVELY QUICK MOVING...SO FLOOD THREAT IS NOT ALL THAT GREAT. GENERALLY EXPECT 1/4 TO 1/2 AN INCH OF RAINFALL WITH LOCALLY HIGHER AMOUNTS. WHILE LOCALIZED URBAN FLOODING CANNOT BE RULED OUT IN ANY HEAVIER DOWNPOURS...IT DOES NOT APPEAR TO BE A SIGNIFICANT THREAT AT THIS TIME. EXPECT GENERALLY A QUARTER AN INCH OR LESS FROM ANY CONVECTION MONDAY AFTERNOON AND EVENING. THE NEXT CHANCE FOR ANY SIGNIFICANT PRECIPITATION WILL BE WITH PASSAGE OF A STORM SYSTEM WEDNESDAY/WEDNESDAY NIGHT. SHOULD THEN HAVE SPOTTY LIGHT PRECIPITATION WITH FRONT STALLED TO SOUTH AND EASTERLY FLOW THU-SAT. && .EQUIPMENT...
