What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|

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.
The nearest sounding before it
Brookhaven, NY (KOKX), launched 12:00Z, 2.6 hours before the alert went out and 102 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, May 19, 5:25 AM EDT, 5 hours 9 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE UPTON NY
525 AM EDT FRI MAY 19 2006
.NEAR TERM (TODAY THROUGH TONIGHT)...
HAVE GONE AHEAD AND UPDATED MORNING GRIDS TO ACCOUNT FOR ADDITIONAL
RAINFALL OVER NYC AND TO SHOW AREA OF MODERATE RAIN MOVING E ACROSS
THE AREA THROUGH THE MORNING HOURS. WILL UPDATE THE AFM/PFM/FTP. ZFP
LOOKS GOOD...SO WILL LEAVE THAT ALONE.
THE FIRST WAVE OF OF LOW PRES...CURRENTLY OVER S NJ...WILL BRING
SHOWERS...PRODUCING LOCALLY HEAVY RAIN...ACROSS THE AREA FROM THE
SOUTH THROUGH THE MORNING HOURS. THIS LOW WILL TRACK NE OVER THE
OCEAN...CROSSING E LONG ISLAND AND E CT JUST AFTER SUNRISE. THERE IS
SOME THUNDER OVER S NJ AND THE DELMARVA PENINSULA...SO A RUMBLE OF
THUNDER CAN/T BE RULED OUT OF THE QUESTION. THE RAIN WILL BE MOVING
FROM W TO E THROUGH THE MORNING RUSH HOUR...TAPERING OFF BY
MID-MORNING.
STATIONARY BOUNDARY LIES JUST W OF THE HUDSON RIVER...AND CAN BE
NOTED BY SFC DEWPOINTS IN THE LOW TO MID 40S ACROSS W NJ AND INTO
THE LWR HUDSON VALLEY...AND IN THE MID 50S ACROSS NYC/LONG
ISLAND/CT. AS SFC LOW MOVES INTO NORTHERN NEW ENGLAND...IT WILL DRAG
THIS STATIONARY BOUNDARY ACROSS THE AREA AS A WEAKENING COLD FRONT.
SINCE THE BOUNDARY WILL BE MOVING INTO A MOIST AND UNSTABLE
ATMOSPHERE...WILL EXPECT ANOTHER ROUND OF SHOWERS AND POSSIBLE
THUNDERSTORMS DURING THE AFTERNOON HOURS. CURRENT NAM SOUNDING SHOWS
CAPE VALUES JUST OVER 1000 AND LI CLOSE TO -5...WHILE GFS SOUNDING
SHOWS CAPE VALUES AROUND 1600 WITH LI CLOSE TO -7. WILL CARRY LOW
CHANCE POPS CLOSE TO COAST...AND HIGH CHANCE POPS FURTHER INLAND.
AFTER SUNSET...WITH LOSS OF DAYTIME HEATING AND WITH BOUNDARY JUST W
OF THE AREA...WILL SEE SHOWERS/TSTMS QUICKLY DIMINISHING AND SKIES
PARTIALLY CLEARING OUT TONIGHT.
BLENDED THE MAV/FWC FOR MAX TEMPS TODAY AND MIN TEMPS TONIGHT AS MET
GUIDANCE WAS ABOUT 5 DEGREES TOO COOL. FEEL THERE WILL BE ENOUGH
BREAKS IN CLOUDS TO WARM THE AREA QUITE NICELY DURING THE AFTERNOON.
&&
.SHORT TERM (SATURDAY THROUGH SUNDAY)...
VERTICALLY STACKED TROUGH ALONG THE NORTHEAST WILL PRETTY MUCH
REMAIN IN PLACE THROUGH THE WEEKEND. WILL SEE UPPER LEVEL SHORTWAVE
ENERGY MOVING ACROSS THE AREA SAT AFTERNOON...AND WILL CARRY CHANCE
POPS FOR SHOWERS/TSTMS FOR THE AFTERNOON/EVENING. A STRONGER
SHORTWAVE AND UPPER TROUGH THEN MOVES ACROSS THE AREA ON SUN
AFTERNOON...KEEPING A CHANCE FOR SHOWERS/TSTMS IN THE FCST. GIVEN
CONVECTIVE NATURE OF SHOWERS/STORMS...THINK MOST PLACES WILL SEE
NICE WX FOR MUCH OF THE WEEKEND...BUT WHEN STORMS FIRE UP...LOCALLY
HEAVY RAIN WILL BE POSSIBLE.
FOR TEMPS...ONCE AGAIN...MET GUIDANCE ABOUT 5-10 DEGREES TOO
COOL...SO BLENDED MAV/FWC GUIDANCE TO GET MAX TEMPS IN THE 60S/LOW
70S ON SAT AND SUN.
&&
.LONG TERM (SUNDAY NIGHT THROUGH THURSDAY)...
ANOTHER CLOSED UPPER LOW DROPS DOWN OVER EASTERN CANADA/NORTHERN NEW
ENGLAND EARLY IN THE PERIOD...WITH A COLD FRONT PASSING THROUGH
SUNDAY EVENING. SURFACE PRESSURE GRADIENT TIGHTENS IN RESPONSE TO
ASSOCIATED SURFACE LOW PRESSURE DEVELOPING OVER THE CANADIAN
MARITIMES...WITH BREEZY CONDITIONS SUN NIGHT AND CONTINUING INTO
MON...THEN DEVELOPING AGAIN DURING THE DAY ON TUE. MOST OF THE TIME
IT SHOULD BE DRY WITH SLIGHTLY BELOW NORMAL TEMPS...BUT HAVE
INCLUDED A SLIGHT CHANCE POP FOR FAR EASTERN CT/LONG ISLAND TUE
AFTERNOON AND EARLY EVENING CLOSER TO CENTER OF DEEP CYCLONIC FLOW.
AFTER THAT...UNCERTAINTY ABOUNDS AS MODELS DISAGREE ON HOW FAST
BLOCKING REGIME WILL BREAK DOWN DURING THE MID TO LATE WEEK PERIOD.
THE 18/12Z GFS KEEPS SURFACE HIGH PRESSURE/UPPER TROUGHING ALOFT
WHICH HOLD A WARM FRONT TO THE SOUTHWEST AT BAY AND KEEP US
DRY...WHILE THE 18/00Z ECMWF LIFTS THE UPPER TROUGH OUT SOONER AND
ALLOWS THE FRONT TO APPROACH IN ZONAL FLOW. HAVE SPLIT THE
DIFFERENCE AND FORECAST SLIGHT CHANCE POP FOR WED NIGHT AND
THU...WITH TEMPS WARMING UP TO NEAR OR A FEW DEGREES ABOVE NORMAL.
&&
.AVIATION...
SURFACE LOW PRESSURE EARLY THIS MORNING WILL MAKE FOR A TRICKY WIND
FORECAST AS IT MOVES ON BY. MAINLY VARIABLE WINDS LESS THAN 10 KTS
EARLY THIS MORNING. RAIN WILL ACCOMPANY THE WAVE ACROSS MOST
TERMINAL SITES THIS MORNING WITH MVFR VSBYS POSSIBLE.
STACKED LOW AND ASSOCIATED INSTABILITY COULD YIELD A FEW TSTMS LATER
THIS MORNING AND THIS AFTERNOON. ONLY INCLUDED IT AT KSWF FOR
NOW...BUT THIS WILL NEED TO BE LOOKED AT AS I EXPECT SOME COVERAGE
THIS AFTERNOON WITH UPPER LOW MOVING OVERHEAD.
ANY SHOWERS/TSTMS MOVE NORTH WITH ROTATING LOW AND LOSS OF DAYTIME
HEATING THIS EVENING. LEFTOVER AC CLOUDS THEREAFTER. WINDS GO FROM
VARIABLE IN THE MORNING TO WEST/SOUTHWEST 10 TO 15 KTS THIS
AFTERNOON...THAN DROP A FEW KTS AT NIGHT.
&&
.MARINE...
GENERALLY LIGHT WINDS AS LOW PRESSURE MOVES ACROSS WATERS. NUMEROUS
SHOWERS AND POSSIBLE THUNDERSTORMS THIS MORNING WITH THIS WAVE.
A STACKED LOW DRIFTING THROUGH THE NORTHEAST WILL KEEP THINGS
UNSETTLED THROUGH THIS WEEKEND. SOUTHERLY FLOW AROUND 15 KT ON THE
OCEAN AND 10 TO 15 KT ON THE SOUND. CHANCE OF A SHOWER OR TSTM BOTH
SATURDAY AFTERNOON AND SUNDAY AFTERNOON.
WEST/SOUTHWEST WINDS INCREASE TO NEAR SCA THIS AFTERNOON/EVENING ON
ALL WATERS BEHIND A STRENGTHENING LOW PRESSURE WAVE MOVING THROUGH
THE WATERS. THEN THEY COME DOWN A BIT SATURDAY.
SW WINDS INCREASE TO NEAR SCA LEVELS ACROSS OCEAN WATERS ONCE AGAIN
DURING THE DAY SUNDAY AHEAD OF...THEN ON THE BACK SIDE OF A STRONG
TROUGH.
BEST CHANCE OF REACHING SCA WIND GUSTS ON ALL WATERS IS SUN NIGHT
INTO MON WITH MODERATE CAA ON NW WINDS BEHIND THE TROUGH.
SEAS WILL REMAIN NEAR MINIMAL SCA LEVELS ACROSS THE OCEAN...WITH 1
TO 2 FOOTERS ACROSS THE SOUND AND HARBOR THIS WEEKEND.
&&
.HYDROLOGY...
RAIN MOVING ACROSS THE AREA THIS MORNING WILL PRODUCE BASIN AVERAGES
OF 1/4 TO 3/4 INCH. RIVERS AND STREAMS SHOULD HANDLE THIS AMOUNT OF
QPF WITH LITTLE PROBLEMS...HOWEVER...URBAN AND POOR DRAINAGE
FLOODING WILL BE POSSIBLE WITH HEAVY SHOWERS THROUGH
MID-MORNING.
