A remnant mesoscale convective vortex (MCV) moved through the mid-Atlantic on the afternoon of May 20. This feature formed in association with a strong convective complex over the southern Plains on May 18, and proceeded to track northeast across the eastern half of the US, producing multiple additional rounds of severe weather as it did so. This included over the mid-Atlantic on May 20. As the MCV moved into the region, a warm and moderately unstable air mass was present over the region. Shear and forcing associated with the MCV caused multiple rounds of thunderstorms to develop during the afternoon. Some storms became severe, with a mixed convective mode leading to instances of damaging winds, hail, and one brief tornado in New Jersey. As the MCV moved offshore, convection diminished during the evening hours.

Tornado in MONMOUTH, NEW JERSEY
From 20-MAY-22 16:09:00 to 20-MAY-22 16:10:00 (EST-5)
Location: MATAWAN
Tornado F-scale: EF0
Crop damage: 0.00K
Reported by: NWS Storm Survey

A National Weather Service storm survey has confirmed a brief EF-0
tornado occurred in Hazlet Township on the evening of Friday, May
20th just after 5 PM EDT.
The tornado began along Line Road on the border between Strathmore
Township and Hazlet Township where several large limbs were blown
off and a couple softwood tree trunks were snapped. The snapped tree
trunks caused collateral damage to utility poles and power lines
near the intersection of Sophia Drive. The center of circulation
continued east-northeast into a residential neighborhood between
Sophia Drive and Carlow Way where the most significant damage from
the tornado occurred. At least a dozen homes in this area sustained
cosmetic damage, including vinyl siding blown off, soffit damage,
gutter damage, and/or roof shingles blown off. The only structural
damage noted was due to a tree falling onto a home which caused some
structural damage to its roof. A few larger softwood trees were
uprooted in the residential area and several vinyl fence sections
were blown over.
The tornado damage path then became somewhat discontinuous as it
crossed the Garden State Parkway toward another residential area
along Park View Drive. A softwood tree sustained significant loss of
limbs and a couple others were uprooted nearby. A utility pole was
also damaged along Park View Drive. A few homes sustained minor
cosmetic damage near the intersections of Linda Place, Beers Street,
and Rutgers Street, then the circulation continued east-northeast
along Rutgers Street toward Bedle Road where several large limbs
were blown off a few trees. A final softwood tree was uprooted along
Bedle Road near Indian Hill Court where the surface circulation
appeared to have dissipated.
No additional damage occurred from this storm as it continued
through the residential area toward Route 35. Four utility poles
were pushed over or broken along Route 35 near the Jiffy Lube auto
shop. However, no additional damage occurred in this area, and thus
it has been determined that the damage to the poles was caused by
straight line winds.
