The episode as NWS BGM wrote it up.
A disturbance moved through Central New York and kicked off scattered showers and thunderstorms. Warm, humid conditions led to an unstable environment with many storms becoming strong to severe. Damaging wind gusts were observed with these storms as there were multiple reports of downed trees and wires throughout the region.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 11, 1:56 PM EST, 1 hour 4 minutes earlier. Its key messages:
Area Forecast Discussion
National Weather Service Binghamton NY
256 PM EDT Thu Jun 11 2026
.WHAT HAS CHANGED...
Adjusted thunderstorm timing for today, pushing arrival times
back by a few hours. Also adjusted thunderstorm chances for
Friday the cold front has been forecast to speed up, limiting
storm chances north of the Southern Tier.
&&
.KEY MESSAGES...
1) High heat and humidity continues today, lasting into Friday. The
weekend will be cooler but temperatures will remain above normal.
2) Multiple systems will traverse the area, kicking off scattered
thunderstorms across the region today and Friday. Some of these
storms could be severe, with damaging winds and hail as the main
threats. Saturday will remain dry but another cold front on Sunday
will bring a return of showers and storms in the afternoon and
evening.
3) A broad upper level trough will bring cooler, more normal
temperatures to start next week with a few periods of light rain
possible.
&&
.DISCUSSION...
KEY MESSAGE 1...
Temperatures have climbed into the mid 80s for most, and are
expected to reach the upper 80s to low 90s by mid afternoon. With
dewpoints in the upper 60s to low 70s, heat indices will reach the
90s for most. Valley locations across the Southern Tier and Finger
Lakes will see values climb above 95F, which prompted the
issuance of a Heat Advisory for these areas until 8pm tonight.
Temps and dewpoints will remain high tonight, falling into the mid
to upper 60s and mid 60s, respectively.
Friday will be warm once again, but a cold front is expected to move
into the area in the late morning hours, which will limit heating
potential across the Finger Lakes and Mohawk Valley. They may see a
brief period of upper 80s before the cold front moves through and
drops temps back into the low 80s. Areas along and south of the
Southern Tier could see temps reach the mid 80s to low 90s during
the afternoon hours ahead of the cold front. With dewpoints in the
mid to upper 60s, heat indices will climb back into the 90s.
Confidence is not high enough to issue a Heat Advisory for
tomorrow afternoon for these areas as questions still remain
with the timing and speed of the front moving through and if
early rainfall limits heating potential.
Behind the front, drier and cooler air will move in with highs in
the low to mid 80s on Saturday with dewpoints in the 50s. A ridge on
Sunday will push temperatures back into the mid to upper 80s before
another cold front pushes through during the afternoon hours.
KEY MESSAGE 2...
The aforementioned heat and humidity will be the fuel that drives
thunderstorm development today and Friday.
A shortwave trough is currently moving across northern OH, kicking
off showers and storms over WPA and WNY. A cap currently remains
over our area, but is expected to erode by 3pm. As the
shortwave kicks eastward, it will provide the broad lift that,
combined with MLCAPE values between 1500-2000 j/kg, will kick
off scattered cellular thunderstorms moving into the area by the
mid afternoon hours. As the axis of the shortwave moves into
the area, the storms should transition into multi cell or linear
segments as they progress across the area late this afternoon
and evening. The main threat with the storms is expected to be
damaging winds and small hail. PWATs in the 1.75-2.0in range
indicate heavy downpours with isolated flash flooding possible,
especially across portions of the Finger Lakes and Mohawk Valley
that saw heavy rain yesterday. Storms should hit the I-81
corridor between 7 and 8pm and exit to the east by 10pm.
Friday will see another round of thunderstorms as a cold front
pushes into the area from the west. Guidance has sped up the arrival
of this cold front, now expected to push into our western areas by
the late morning hours. This will limit CAPE values north of
the Southern Tier. Vertical wind shear looks to be lacking ahead
of and along the front as well, with values only approaching
20kts or so. With the severe storm ingredients somewhat
misaligned, severe storms north of the Southern Tier currently
look to be isolated at this time. A few storms may be able to
become severe if they can tap into a localized area that has
higher CAPE values and moisture, allowing strong downbursts to
occur when the updrafts cannot hold the rain any longer. The
best chance for severe weather looks to be along and east of the
I-81 corridor as CAPE values should be the highest here and
mid-level winds are forecast to increase, allowing for better
storm organization and stronger winds to develop. Main severe
weather impacts expected are damaging winds and hail. Rain
should move east of the area by the evening, bringing a cooler,
dry night.
Dry weather remains through Saturday and into Sunday as a ridge
moves overhead. A trough approaches Sunday afternoon with an
associated cold front that should kick off scattered showers and
storms across the area during the afternoon and evening hours. Some
of these storms could be severe.
KEY MESSAGE 3...
Near normal temperatures will return to start next week as a
broad trough sits over the northern portion of the country.
This will bring a period of beautiful weather with highs in the
70s and dewpoints in the upper 40s to low 50s. Rain returns by
mid week as the trough axis swings through the eastern US.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Conditions will remain VFR throughout most of the afternoon and
evening, though showers and thunderstorms are expected. Some
storms may become strong to severe with strong wind gusts,
higher than what is mentioned in the TAFs. While tempo groups
were used for the best estimated timing for storms, some
amendments will likely be needed once storms develop. Guidance
keep storms south of RME, so confidence was too low to include
thunder there. Restrictions will be possible with
showers/storms, especially if they pass directly over a
terminal.
Once the showers move out, conditions may be briefly VFR. Fog
will be possible at all terminals tonight but confidence is low
at SYR and RME where skies may take longer to clear out. Given
the added moisture from the rain and winds being light, any
clearing will likely result in fog. IFR to LIFR fog is expected
at ITH, ELM and potentially RME, though cannot be ruled out at
other terminals. Timing of when the fog lifts is uncertain but
conditions should gradually improve after 12z though some MVFR
ceilings are expected to stick around at RME and SYR through the
end of this TAF period.
Winds will be breezy this afternoon with some gusts up to 15
kts. As mentioned, stronger winds may be observed in showers and
storms. Tonight, winds become calm before picking back up to 5
to 10 kts by Friday afternoon.
Outlook:
Friday Night...Mainly VFR; fog and restrictions late overnight.
Saturday...Mainly VFR
Sunday...Showers and thunderstorms with associated restrictions
possible.
Sunday night through Monday...Mainly VFR; early morning fog and
restrictions possible.
Tuesday...Low chance for afternoon showers and thunderstorms
and associated restrictions.
