The radar
The Boston radar (KBOX), 92 km from the middle of the area, began a volume at 19:09 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Chatham, MA (KCHH), launched 12:00Z, 7.1 hours before the alert went out and 10 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
National Weather Service Boston/Norton MA
221 PM EDT Tue Sep 18 2018
.SYNOPSIS...
The remnants of Florence will bring heavy rainfall along with
the threat for flash flooding to Rhode Island and southeast
Massachusetts the remainder of this afternoon. High pressure
will build south from eastern Canada with a gusty northeast wind
Wednesday and Thursday. A warm front will lift north Thursday
night, with southerly winds bringing mild temperatures on
Friday. A cold front will sweep across the region Friday night,
with mainly dry but cooler conditions for the upcoming weekend.
&&
.NEAR TERM /UNTIL 7 PM THIS EVENING/...
2 PM Update...
Flash Flood Threat...
We have dropped the Flash Flood Watch for much of CT and western
MA as heavy rain has moved east of that area. Despite the
heaviest rain confined to RI and southeast MA will continue with
the Flash Flood Watch for central and eastern MA as rivers and
streams continue to rise in this area and may have to be
followed up with river flood warnings shortly. Otherwise heavy
rain will be confined to southern RI and southeast MA over the
next few hours. SPC mesoanalysis continues to show PWATs up to
2.1 inches across RI and southeast MA along with surface dew pts
into the low and mid 70s. Thus tropical airmass and strong
forcing for ascent along the frontal boundary will continue to
yield tropical downpours with hourly rainfall rates of 1-2"
inches at times.
Tornado threat...
SPC Mesoanalysis still capturing 1500 j/kg of SB cape across RI
into southeast MA along with low level shear of 20-25 kts. Thus
low risk for rotating storms the next few hours as this line of
convection heads toward the south coast.
Otherwise back edge of the rain shield will move across the
region late this afternoon/early evening with a wind shift from
SSW to NNE and not as warm or humid with dew pts falling from
the low to mid 70s into the 60s.
&&
.SHORT TERM /7 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
Showers and heavy rainfall threat will move south of the coast
this evening followed by a mostly dry night. However, areas of
drizzle may develop overnight in eastern New Eng as NE flow
develops. There is a strong signal for stratus and fog
overspreading the region from the Gulf of Maine.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Highlights...
* Fast wind flow aloft will bring changeable conditions into
next weekend
* A warm front pushes north Thu night, followed by a cold front
late Fri night into early Sat
* Below normal temperatures through mid week, then briefly mild
late week before a return to cool readings
Overview...
H5 short wave will push E through around midday Wednesday.
There may be a few leftover showers or some spotty drizzle
during the morning, then conditions should improve though it
will remain cool with a gusty northeasterly wind. Mid level
ridging builds across the Great Lakes into south central
Canada, keeping a general W-NW steering flow in place across
the northeast through most of this period. High pressure builds
across through mid week, bringing dry conditions but a
persistent onshore wind flow that will keep temperatures below
normal.
A short wave rides eastward in the fast flow aloft by late this
week, with a warm front approaching Thu night into Fri. A few
showers may push into NW Mass Thu night with the front, but most
of the precip looks to remain out of the region. Winds will
shift to southerly by around daybreak Friday. Dewpoints will
increase as well, so there could be some patchy fog developing
during the early morning hours Fri. Will see mild temps, with
readings topping off in the 70-75 degree range Fri afternoon.
However, with the mid level ridge pushing across the region,
will see another cold front approach Fri night, bringing
scattered showers and possibly a few thunderstorms.
The front pushes offshore Sat morning, with another large high
building out of central Canada. This will bring another shot of
dry but cool conditions through the upcoming weekend into early
next week.
