What was reported inside it

Time	Report	Where	Remark
Apr 19, 11:28 PM EDT	MARINE TSTM WIND 46	Westhampton Beach Airpo, NY	ASOS REPORTED 40 KNOT WIND GUST NEAR SOUTH SHORE OF LONG ISLAND.

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 00:00Z, 3.3 hours before the alert went out and 34 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.

SVR TSTM WATCH 135 ISSUED THROUGH 11 PM FOR ORANGE AND ROCKLAND
COUNTIES IN NY AND ALL NJ ZONES. DAMAGING WINDS IS THE MAIN THREAT.

ISSUED A DENSE FOG ADVSY FOR MOST COASTAL ZONES. THE COMBINATION
OF A MOIST SOUTHERLY FLOW AND THE LOSS OF HEATING SHOULD ALLOW FOG
TO ADVECT FROM THE OCEAN WATERS ON TO LAND RESULTING IN VERY LOW
VSBYS UNTIL THE SHOWERS/TSTMS MOVE IN ASSOCIATED WITH A COLD FROPA
TONIGHT. OTHERWISE...ADJUSTED POPS BASED ON LATEST RADAR DATA.
WATCHING THE LINE OF CONVECTION CLOSELY IN EASTERN PA. EXPECTING
IT TO MOVE INTO NJ AND WESTERN LOWER HUDSON VALLEY BETWEEN 9 PM
AND 10 PM...NYC AND WESTERN LONG ISLAND/CT BETWEEN 10 PM AND
MIDNIGHT AND THE REST OF THE AREA BETWEEN MIDNIGHT AND 3 AM. LOW
LEVEL WINDS RANGING BETWEEN 60 AND 70 KT PER TJFK/TEWR AND KOKX
