What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Jun 27, 3:40 PM EDT | HAIL 0.88 | White Plains, NY |
Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jun 27, 3:18 PM EDT, 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 318 PM EDT WED JUN 27 2007 .SYNOPSIS... THE BERMUDA HIGH WILL BRING HOT AND HUMID WEATHER TO THE REGION THROUGH THURSDAY. A COLD FRONT WILL MOVE ACROSS THE REGION THURSDAY AFTERNOON AND EVENING. DRIER AND COOLER WEATHER WILL RETURN ON FRIDAY AND CONTINUE THROUGH EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... TEXT AND GRIDDED FORECASTS UPDATED TO ACCOUNT FOR THE ISSUANCE OF SEVERE THUNDERSTORM WATCH 456..EFFECTIVE UNTIL 8 PM EDT...FOR THE LOWER HUDSON VALLEY...SW CONNECTICUT (FAIRFIELD AND NEW HAVEN COUNTIES)...AND PART OF NE NJ (BERGEN AND PASSAIC COUNTIES). LARGE HAIL AND DAMAGING WIND GUSTS ARE THE PRIMARY THREATS. ANOTHER HOT...HAZY AND HUMID DAY IN STORE. BERMUDA HIGH OFFSHORE WITH ASSOCIATED SW SFC WINDS WILL CONTINUE PUMPING HIGH DEWPOINT AIR INTO THE REGION. 5H HGTS BEGIN TO FALL TODAY AS THE STRONG UPPER RIDGE THAT CAPPED US AND PREVENTED CONVECTION ON TUE STARTS TO BREAK DOWN. HIGH INSTABILITY WILL BE PRESENT AGAIN THIS AFTERNOON WITH TEMPS IN THE 90S AND DEWPOINTS IN THE UPPER 60S TO NEAR 70. LIMITING FACTOR WILL BE LACK OF STRONG FORCING/FOCUS MECHANISM. A WEAK LEE-SIDE SFC TROF AND MID LEVEL VORT WILL BE THE LIKELY TRIGGERS FOR CONVECTION TO THE NW OF NYC. THUS...HAVE INCREASED THE POPS TO LIKELY IN THIS AREA...WHILE LEAVING NYC...LONG ISLAND...AND SE CT IN THE SLIGHT CHANCE TO CHANCE CATEGORIES AS STABILITY/FORCING FACTORS WILL BE LESS FAVORABLE FOR CONVECTION NEAR THE OCEAN. HAVE ALSO CONTINUED WITH MENTION OF HEAVY RAIN AND GUSTY WINDS... AS PWATS INCREASING TO ALMOST 2 INCHES AND WEAK LOW LEVEL FLOW COULD ALLOW FOR SLOW STORM MOTIONS WITH SOME LOCALLY EXCESSIVE DOWNPOURS AND POSSIBLY AN ISOLATED WET MICROBURST. FAVORED THE HOTTER MAV MOS GUIDANCE TODAY...AS MAX TEMPS SHOULD BE SIMILAR TO THOSE SEEN ON TUE. DEWPOINTS IN THE UPPER 60S TO AROUND 70 WILL RESULT IN HEAT INDICES FALLING JUST SHORT OF ADVISORY LEVELS... IN THE UPPER 90S ACROSS NYC...NE NJ AND PORTIONS OF INTERIOR SRN CT. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/... WARM/HUMID/HAZY WX CONTINUES TONIGHT. CONTINUED WITH CHANCE POPS WEST/CENTRAL AND SLIGHT CHANCE COAST. GFS APPEARS TO BE OVERDONE WITH ITS DEPICTED ALL-NIGHT RAIN AND FAVOR THE DRIER NAM WHICH SHOWS LITTLE PRECIP AFTER DARK. CANNOT RULE OUT CONVECTION HOWEVER WITH HIGH MOISTURE LEVELS AND LEE SIDE TROF LINGERING TO THE WEST. OVERNIGHT LOWS WILL BE QUITE WARM WITH MOST LOCATIONS STAYING IN THE 70S. COLD FRONT WILL APPROACH THE AREA THURSDAY AFTERNOON. HAVE CONTINUED THE FCST OF SHOWERS/TSTMS LIKELY IN THE AFTERNOON. SOUTHERN EDGE OF STRONG MID LEVEL WIND BELT WILL AFFECT THE AREA THU AFTERNOON. WITH FCST 0-6KM SHEAR VALUES OF 30-40 KT...THERE WILL BE AN INCREASED POTENTIAL FOR ORGANIZED MULTICELL SEVERE WITH DAMAGING WINDS. URBAN FLOODING AND LOCAL FLASH FLOODING ALSO A THREAT DUE TO THE HIGH PWATS AROUND 2 INCHES AND TRAINING OF CELLS. TEMPS ON THURSDAY SHOULD BE A COUPLE OF TICKS LOWER DUE TO THE ADDITIONAL CLOUD COVER. THE COLD FRONTAL PROGRESSION WILL BE SLOWER LATE THURSDAY AND THURSDAY NIGHT...WHICH WILL LIKELY KEEP THE BOUNDARY CLOSE ENOUGH TO KEEP MENTION OF CONVECTION IN FOR THURSDAY NIGHT. 00Z MODELS ARE A BIT SLOWER IN MOVING THE FRONT SOUTH OF THE AREA ON FRIDAY...WITH A WEAK SFC WAVE DEVELOPING IN THE NRN MID ATLANTIC AND MOVING SOUTH OF LONG ISLAND DURING THE DAY. PRECIP ASSOCIATED THIS THIS WILL BE QUITE CLOSE TO THE COAST...AND POSSIBLY AFFECTING LONG ISLAND/NYC AND PARTS OF NE NJ. ADDED CHANCE POPS SOUTH AND SLIGHT CHANCE NORTH FOR FRI MORNING TO COVER THIS POTENTIAL. FRONT SHOULD PUSH FAR ENOUGH SOUTH BY FRI AFTERNOON TO ALLOW THE DRIER/COOLER AIRMASS TO MOVE FIRMLY INTO THE REGION WITH PRECIP ENDING. WITH THE COOLER AIR MOVING IN AND PROBABLY A GOOD DEAL OF CLOUD COVER AROUND THROUGH MUCH OF FRIDAY... MAV MOS RESPONDED AND SHOWS HIGHS ONLY IN THE UPPER 60S TO LOWER 70S. DID NOT GO QUITE THAT COOL YET...BUT DID TREND THE PREVIOUS FCST COOLER AND WILL SHOW LOWER-MID 70S. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... HIGH PRES ORIGINATING FROM CANADA WILL DOMINATE AREA WEATHER FRI NIGHT THROUGH MON...POSSIBLY SETTING UP FOR AN UNBELIEVABLY COMFORTABLE WEEKEND. WILL EXPECT HIGH TEMPS IN THE UPPER 70S TO NEAR 80...LOW TEMPS AROUND 60 IN/AROUND NYC...MID TO UPPER 50S ELSEWHERE...AND SFC DEW POINTS ONLY IN THE 50S. BLOCKING RIDGE IN THE CENTRAL PART OF THE COUNTRY WILL KEEP A PERSISTENT WEAK TROUGH OVER THE NORTHEAST. THIS WILL KEEP TEMPERATURES WELL BELOW NORMAL...AND A LOW LEVEL NORTHERLY COMPONENT TO THE WINDS WILL KEEP DEW POINTS REFRESHINGLY LOW FOR THE WEEKEND. HOWEVER...THE PRESENCE OF THE TROUGH ALOFT MAY ALLOW FOR SOME INSTABILITY SHOWERS/TSTMS ON SUN OVER EASTERN PORTIONS OF THE CWA...AS A WEAK SHORTWAVE ROTATES AROUND THE BASE OF THE TROUGH. THIS PATTERN WILL START TO BREAK DOWN EARLY NEXT WEEK...BUT WE WONT SEE THAT BIG OF A SHIFT IN THE PATTERN UNTIL A KICKER SHOWS UP IN THE CANADIAN PLAINS MIDWEEK TO SHARPEN A DEVELOPING TROUGH. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... A WARM AND HUMID AIRMASS WILL REMAIN ACROSS THE TERMINALS THROUGH THURSDAY AFTERNOON WITH BERMUDA HIGH PRESSURE DOMINATING. A SOUTHWEST TO AT TIMES SOUTHERLY FLOW WILL KEEP PUMPING A WARM HUMID AIRMASS INTO THE REGION. SEABREEZES WILL TURN WINDS TO THE SOUTH AROUND 15 KT AT COASTAL LOCALES...WHILE INLAND TERMINALS REMAIN SOUTHWEST AT MORE OF A 5-10 KT FLOW. ALL TERMINALS SHOULD REVERT TO A MORE GENERAL SOUTHWEST FLOW AT 5 TO 10 KT AROUND DUSK. HAZE WILL RESTRICT VSBY TO LOW END VFR AND MVFR THROUGH THE TAF PERIOD. THERE IS NOT EXPECTED TO BE ANY IMPROVEMENT IN THIS AREA UNTIL WINDS TURN NORTHWEST BEHIND THE COLD FRONT THURSDAY NIGHT. CEILINGS OUTSIDE OF CONVECTION WILL REMAIN AT OR ABOVE ABOUT FL100. IN AND AROUND WDLY SCT SHRA AND TSRA...LOW END VFR AND MVFR CIGS WILL ACCOMPANY CONVECTION. MOST OF THIS ACTIVITY SHOULD REMAIN NORTH AND WEST OF THE CITY TERMINALS...BUT COULD AFFECT WESTERN AND NORTHERN APPROACHES INTO THE NY METRO AREA. ISOLD-WDLY SCT COVERAGE OF SHRA AND TSRA IS EXPECTED TO PERSIST UNTIL AROUND 00Z OR SO. HAZARDS ASSOCIATED WITH CONVECTION WILL BE SMALL HAIL...LOCALLY GUSTY WINDS...TORRENTIAL RAINS AND FREQUENT LIGHTNING. OUTLOOK FROM 18Z THURSDAY THROUGH SUNDAY...BETTER CHC FOR TSTMS THROUGHOUT THE AREA THURSDAY AS A COLD FRONT MOVES INTO THE REGION LATE IN THE DAY. MVFR CONDITIONS LIKELY IN ANY THUNDERSTORMS WITH LOCALIZED IFR POSSIBLE. DAMAGING WINDS AND/OR HAIL WILL BE POSSIBLE WITH THESE STORMS. AFTER THE FRONT PASSES LATE THURSDAY NIGHT HIGH PRESSURE BUILDS IN FROM THE NORTH WITH VFR CONDITIONS THROUGH SUNDAY. && .MARINE... A BERMUDA HIGH ANCHORED OVER THE WESTERN ATLANTIC AND A HIGH AMPLITUDE RIDGE ALOFT WILL KEEP THE COASTAL WATERS IN A SUMMERTIME PATTERN THROUGH THU. THE PRESSURE GRADIENT WILL TIGHTEN TODAY WITH THE APPROACH OF A COLD FRONT. WINDS SHOULD REMAIN BELOW SCA WITH A STRENGTHENING INVERSION OVER THE WATERS...WITH THE EXCEPTION OF WINDS FLIRTING WITH SCA LATE THIS AFTERNOON INTO THE EVENING ACROSS THE WESTERN OCEAN WATERS WITH COASTAL JET DEVELOPMENT. IN TERMS OF SEAS...CONFIDENCE WITH WAVEWATCH GUIDANCE IS POOR. HAS BEEN RUNNING HIGH IN THESE WAA PATTERNS...AND IS CURRENTLY RUNNING 1 TO 2 FT TOO HIGH. WITH S/SW FLOW INCREASING TO 15 TO 20 KT...SEAS BY LATE TONIGHT/THURSDAY MAY BUILD TO MARGINAL SMALL CRAFT LEVELS ON THE OCEAN WATERS. BUT SINCE THIS LOOKS TO BE A MARGINAL 2ND/3RD PERIOD EVENT...WILL HOLD OFF FOR NOW AND LET DAYSHIFT RE- EXAMINE THE STRENGTH OF THE GRADIENT...DEGREE OF MIXING...AND RESULTANT WAVE GENERATION. THE COLD FRONT WILL SLOWLY MOVE THROUGH THE AREA THURSDAY NIGHT WITH SEAS LIKELY FLIRTING WITH MARGINAL SMALL CRAFT LEVELS ON THE OCEAN UNTIL THE WINDS SHIFT TO THE NORTHWEST. THE FRONT MAY STALL JUST SOUTH OF THE WATERS FRIDAY WITH WAVES OF LOW PRESSURE MOVE ALONG THE FRONT. FOLLOWING THE COLD FRONTAL PASSAGE EARLY FRI MORNING...HI PRESSURE OVER THE UPPER MIDWEST BUILDS SEWD...KEEPING THE WATERS UNDER A NW FLOW AND SUB SCA. && .HYDROLOGY... SCATTERED INLAND AFTERNOON CONVECTION TODAY AND THIS EVENING COULD RESULT IN LOCALIZED 1 TO 2 INCH AMOUNTS. WEAK LOW LEVEL WINDS WILL ALLOW FOR SLOW STORM MOVEMENT WHICH WOULD PROMOTE HIGH RAINFALL TOTALS. LOCALIZED URBAN/SMALL STREAM AND EVEN ISOLATED FLASH FLOODING WILL BE POSSIBLE. BETTER COVERAGE OF CONVECTION THURSDAY AFTERNOON WITH FRONTAL PASSAGE BUT FASTER STORM MOTIONS WILL RESULT IN ANOTHER POTENTIAL FOR FLOODING...MAINLY URBAN/SMALL STREAM BUT POSSIBLY SOME LOCALIZED FLASH FLOODING AS WELL. SOME RAIN MAY LINGER INTO FRIDAY MORNING...THEN DRY FRIDAY AFTERNOON THROUGH THE WEEKEND. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE. NJ...NONE. MARINE...NONE. && SYNOPSIS...
