The episode as NWS BGM wrote it up.
With a frontal boundary located just north of the region, Northeast Pennsylvania was in a very moist and unstable environment. Thunderstorms developed with the heating of the day and along colliding outflow boundaries. Some storms became severe with damaging wind gusts as the main impact.

Area Forecast Discussion
National Weather Service Binghamton NY
138 PM EDT Sat Jun 22 2024
.SYNOPSIS...
Hot and humid conditions will continue through the weekend, with
scattered thunderstorms this afternoon into the evening with
even more on Sunday, as a cold front sweeps through the area.
Some stronger storms may produce damaging winds and torrential
rainfall. Heat and humidity will subside Monday and Tuesday
behind the front. Showers and thunderstorms look to return on
Wednesday.
&&
.NEAR TERM /THROUGH SUNDAY/...
120 PM update...
Showers and thunderstorms are developing across the region with
SPC mesoanalysis showing good amounts of Mixed Layer CAPE above
1500 for much of the area. A surface boundary is dropping south
through CNY with stable air behind the boundary. There will
likely be some additional destabilization north of the boundary
as there is still plenty of time for reheating. With 25 to 35
knots of 0-6 km shear this afternoon, there is a threat for
damaging winds and hail with any of the stronger storms.
Tonight there is a surface low moving through the Great Lakes
region with our area in the warm sector. Stronger boundary layer
winds should limit fog development but some of the deeper river
valleys may still get fog to develop by sunrise. The warm front
may dip a bit south tonight with the I-90 corridor possibly
getting another round of late night and early morning
convection.
Tomorrow will be another hot day but as the surface low moves
east through the NY/CAN border, a cold front will drop through
the region triggering another round of thunderstorms. With the
low to the north, shear will be better tomorrow (30kt to 40kt
0-6 km shear) in the warm sector and the 12Z models were a
little slower with the timing of the front so there would be
more time for destabilization across the Southern Tier and
southward. CNY may still have morning convection that will limit
the amount of sun as well as create cold pools that inhibit
much destabilization. Forecast soundings have similar amounts
of CAPE as we have had the past few days but better turning with
height so all severe threats are possible tomorrow.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
345 AM Update...
The positively tilted trough will continue to influence the weather
for our CWA through Sunday night. Lingering showers will remain
behind the cold front as the upper level trough lags behind the
surface cold front and a mid- level shortwave ripples through
the overall trough pattern during the overnight hours. To help
boost precipitation chances, the upper level trough axis will
swing across our northern counties later in the night. Showers
and isolated thunder chances will be the highest (40-60%) north
of the Southern Tier during the overnight hours. We will finally
get a reprieve of hot overnight temperatures as lows will fall
into the upper 50s to mid 60s. Dewpoints will fall into in the
low 60s so it will still feel a little sticky out, but should be
noticeably different than what we have been dealing with.
Guidance remains a little unsure on how much the trough will be
positively tilted and how fast it moves through the region on
Monday, so precipitation chances were extended into the afternoon
hours. Temperatures will rise into the low to mid 70s across much of
the area thanks to northerly flow that will push a Canadian airmass
into the region. With this airmass comes much less humid air, with
dewpoints in the mid to upper 50s. Another ridge will build in from
the west during the evening hours, which will clear us out and allow
radiational cooling to drop overnight lows into the 50s.
Tuesday will see the ridge axis slide east of us once again,
bringing SW flow and warm temperatures back to the region. Highs
will climb into the 80s, with higher elevations in the low 80s and
valleys in the upper 80s. Luckily, dewpoints should remain in the
upper 50s during the hottest part of the day so we should miss out
on sweltering heat we experienced this past week. This ridge
will be transient and not nearly as strong as the one we are
currently under. The next trough will move into the Great Lakes
Tuesday night, allowing for a slight chance of rain showers over
the Finger Lakes. Overnight lows will be in the 60s.
&&
.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
350 AM Update...
Active weather returns Wednesday into Thursday morning as a
broad trough pattern returns to the area. A series of shortwaves
will move through during the morning and early afternoon hours,
generating scattered showers across the area. Guidance shows a
cold front moving in sometime later in the afternoon to late
evening hours. The timing of this will greatly determine the
severe weather chances for the day with an afternoon arrival
having the highest chance. WPC also has us in a marginal chance
for excessive rainfall Wed into Thurs morning, which is backed
up by the chance for multiple periods of heavy rainfall. We will
have to keep a close eye on this setup.
High pressure fills in behind the cold front, bringing a nice
end to the work week.
&&
.AVIATION /17Z SATURDAY THROUGH WEDNESDAY/...
Showers and thunderstorms are developing once again this
afternoon. SYR and RME had storms this morning so it will take
time to destabilize the air mass so thunder was omitted as
confidence is low into at least the early evening. Similar to
this morning, there could be a round of late night into early
morning convection at SYR and RME again.
Storms have already developed in PA with AVP likely seeing
storms soon and will persist into the evening. BGM and ELM will
also see storms develop by 20Z and persist into early evening as
well but less coverage than AVP. ITH will be on the north end of
the best instability so confidence in thunder at the airport
was lower so left showers for now.
Some fog may develop at ELM and that is dependent on whether or
not there is rain this afternoon at and around the terminal.
Tomorrow will be another day with showers and thunderstorms
developing. These storms look to be on the stronger side with
strong wind gusts and hail possible starting in the late morning
into early afternoon. Storms will likely be after 18Z so left
thunder out of the TAFs for now at all terminals for tomorrow.
Outlook...
Sunday Afternoon into Monday Morning...Widespread showers and
thunderstorms Sunday with associated restrictions, mainly to
visibility. Lingering restrictions possible in showers early
Monday.
