The episode as NWS GYX wrote it up.
An unseasonably hot and humid airmass was firmly in place across New England with highs well into the 80s across the interior areas away from the coast. A surface cold front swung through the state during the afternoon triggering thunderstorms across southwest New Hampshire. A few of these storms became severe with isolated damaging wind gusts and large hail being reported.

Area Forecast Discussion
National Weather Service Gray ME
354 PM EDT Sun May 22 2022
.SYNOPSIS...
Heat and humidity linger through this evening away from the
coast before a cold front brings cooler and drier conditions
tonight. This cold front will bring the threat for severe
thunderstorms this afternoon and evening with the main threats
being large hail, damaging winds, and torrential downpours. High
pressure builds in behind the front Monday bringing fair
weather through Wednesday with temperatures closer to normal and
much lower humidity levels. A frontal system will approach
towards the end of the work week for unsettled conditions
possible Thursday and Friday.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
Both the heat and thunderstorm threat are evolving about as
expected this afternoon. A few strong thunderstorms have already
developed so far this afternoon, but more activity is expected
to initiate over the next few hours. Low level lapse rates have
become unstable away from the coastline, but at the same time
mid level lapse rates have become less unstable than earlier in
the day. This is confirmed by CAR's 18z sounding. With this
changing environment, some poorly organized clusters of storms
are expected, with the threat of large hail and damaging winds
continuing. With DCAPE values approaching 1000 J/kg, wind
continues to appear to be the most widespread threat from these
storms. The SPC has issued a severe thunderstorm watch through
10PM this evening away from the coastline for these conditions.
Storms are expected to develop and strengthen over the next few
hours, and then gradually weaken through the evening hours as
they continue moving eastward this evening. Showers and possibly
a few strong thunderstorms arrive at the coast last. The cold
front clears the area and brings cooler and drier air in
overnight tonight.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
More seasonable temperatures return tomorrow with drier air and
mainly sunny skies. Offshore winds help to bring some coastal
areas warmer afternoon highs than they've seen the last couple
of days. A large ridge of Canadian high pressure begins building
in tomorrow through tomorrow night. Under the influence of the
high, temperatures will likely cool into the 30s and 40s
tomorrow night across the area.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
No major changes to the long term forecast. High pressure
builds in early to midweek, then a cold front brings an
increased chance of POPs by Thursday. A trough arrives behind
the front with below normal temperatures likely for the first
half of the weekend.
&&
.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
Short Term...Some marine fog and stratus continues at RKD.
Elsewhere, VFR conditions are expected through this afternoon
and evening. Interior terminals likely see a few thunderstorms
this evening, starting first across western and northern
terminals, with some heavier rain showers arriving at the
coastal terminals later this evening. VFR conditions are then
expected late tonight through tomorrow night as drier air
returns to the area.
Long Term...Generally VFR conditions are expected early to
midweek under an area of high pressure. Some morning valley fog
is possible across interior terminals. A cold front then brings
an increased chance of showers late in the week. Clearing is
expected by early next weekend.
&&
.MARINE...
Short Term...Conditions are expected to remain below SCA
conditions, but a passing cold front may bring some
thunderstorms and gusty winds this evening. Conditions clear
later tonight as high pressure builds in.
Long Term...High pressure brings tranquil conditions through
midweek, then an approaching cold front likely brings SCA
conditions in southwesterly flow ahead of the front by Thursday.
