What forecasters said that day
The local office's own words before this heat advisory went out, 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 this heat advisory went out at Aug 11, 2:00 AM EDT, 1 hour 15 minutes earlier.
Area forecast discussion, Aug 11, 2:00 AM EDT, 1 hour 15 minutes before
Area Forecast Discussion
National Weather Service Binghamton NY
200 AM EDT Wed Aug 11 2021
.SYNOPSIS...
Hot and humid weather continues today through Friday along with
daily chances for scattered afternoon thunderstorms. A few
storms could contain damaging winds and locally heavy rainfall.
Though showers and thunder could linger a bit into Saturday,
drier and cooler weather eventually returns over the weekend.
&&
.NEAR TERM /THROUGH TONIGHT/...
200 AM Update...
The existence of instability aloft is being realized in the
form of small convective clusters of showers and embedded
thunder in Northeast PA-Catskills NY, as well as north of the NY
Thruway. It is occurring with the help of a passing shortwave,
though this activity will wane towards dawn.
Previous discussion...
Some adjustments with the shower and thunderstorm coverage with
the late evening update for the first part of the overnight
hours as another shortwave enters the Twin Tiers. This
shortwave may have just enough to kick off an additional cluster
of showers and thunderstorms like the HRRR has but confidence
is not high. All rain showers should be out of the area by
sunrise. For most of the region though continued the trend from
the early evening update with lowering rain chances for most
locations overnight.
Wednesday will start out dry but will also be much more of the same
during the afternoon. Ridging and southwest flow will continue to
bring warm, moist air into the region, leading to another hot and
humid day. A Heat Advisory is in effect for all of CNY and NEPA for
Wednesday. Heat indices will approach 100, especially in valley
locations. Higher elevations should be limited to the heat
indices in the mid 90s. High temperatures will be in the upper
80s and lower 90s once again, and with less cloud cover
expected, temperatures should have an easier time getting that
high.
Another shortwave is expected to pass through the region bringing
afternoon showers and thunderstorms once again. Modeled CAPE values
are expected to be quite high once again, with values near 2000 J/kg
in the afternoon, though the NAM has values well exceeding that.
Bulk shear is limited to about 20 to 25 kts. PWATs will be 1.5 to
1.8" so locally heavy rainfall is expected. Damaging wind gusts will
be the main threat, but small hail might also be possible.
Scattered showers and thunderstorms would be possible during the
overnight hours Wednesday night and into early Thursday morning.
Overnight lows are expected to be quite warm with most not dropping
below 70.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY/...
220 pm update...
Main concerns in the short term are focused on the continued
heat and humidity, and threat of thunderstorms in the afternoon
and evening hours both Thu and Fri.
The synoptic pattern will remain defined by broad cyclonic flow
across the Great Lakes and the Northeast. However, there still
remains a large amount of uncertainty regarding the progression
of convective complexes the day/night before and any lingering
storms and/or cloud cover which would linger over the region and
inhibit destabilization through the morning and into the
afternoon. The persistent nature of the clouds and convection
will also wreak havoc on temperature/heat index forecasts. At
this time it appears most of the region will see heat indices
into the mid to upper 90s...to around 100 in the valleys.
However, if enough cloud cover hangs around, it could ratchet
those numbers down 3 to 5 deg.
Model guidance is indicating a wedge of relatively drier air
pushing in Thursday morning, which would allow for rapid solar
insolation and a significant amount of boundary layer
instability to form as temperatures climb quickly into the upper
80s and lower 90s with low 70 dew points. A couple thousand
J/kg of ML CAPE and steep low level lapse rates will set the
stage for deep convection later in the afternoon as yet another
short wave trough pushes through central NY and ne PA. The main
threats will be damaging winds and heavy rainfall.
Friday will be another interesting/challenging day in
determining how much early morning cloud cover lingers and also
how the next incoming s/w progresses through the region. Once
again, model guidance shows a narrow corridor of drier air in
the morning followed by a front from the west later in the day.
The difference on Friday is the slow-moving nature of the front.
There does appear to be a building ridge over the Atlantic that
slows down the overall synoptic movement, and will possibly
result in the front checking up across the Northeast into
Saturday. The combination of a deep plume of moisture...PWs
around 2"...and this slow moving system could result in a threat
of heavy rain/flash flooding late Friday into Saturday. Will
need to keep an eye on how this system evolves through the next
couple days.
The heat and humidity will almost certainly continue on Friday,
but with slightly lower temperatures and humidity as the drier
air starts to move in from the w/nw. The hottest air will likely
be over ne PA...into the lower 90s. While the Finger Lakes and
Mohawk valley will be in the mid to upper 80s.

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
220 pm update...
As mentioned above, the front that becomes draped across the
region on Friday will linger Fri night into Saturday as the
overall flow pattern slows down due to a building ridge in the
Atlantic. This will likely allow for additional cloud cover and
scattered showers and storms to linger/persist into Saturday
afternoon...most likely east of I-81 and south of the NY/PA
border. High temperatures on Saturday will warm only into the
mid 70s to mid 80s with noticeably lower humidity. High pressure
really pushes in late Saturday and through the rest of the
weekend with dry and cooler weather expected. Sat night lows
will dip into the mid to upper 50s, and highs on Sunday will
only rise into the mid 70s to lower 80s under mostly sunny
skies. The dry/quiet weather should persist into Monday as well,
but cloud cover could be on the rise along with
temperatures/humidity...back into the lower 80s for highs and
lower 60s for dew points.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
Other than some MVFR ceilings at KELM-KRME early this morning,
mostly VFR is expected this TAF period. However, weak passing
waves within a very warm and humid environment will result in
small clusters of showers and thunder being possible for any of
the terminals, including brief showers prior to dawn for KRME-
KAVP. PROB30 thunder groups were introduced for the next
expected wave at KSYR-KRME for late this afternoon, though
confidence is not very high. It is at least possible at the
other terminals as well this afternoon-early evening, though
with even more uncertainty and thus thunder is not included in
TAFs for KELM-KITH-KBGM-KAVP at this time. Other than local
light ESE wind at KRME during nighttime periods, winds for the
terminals will generally be southwesterly 4-8 knots.
Outlook...
Late Wednesday Night through Saturday...An active period of
daily scattered afternoon-evening thunderstorms, with associated
occasional restrictions.
Saturday night through Sunday...Mainly VFR.
