Area Forecast Discussion
National Weather Service Binghamton NY
459 PM EDT Fri Sep 8 2023

.SYNOPSIS...
A slow moving front will continue to bring several rounds of
showers and thunderstorms to the region through the weekend. A
brief break is possible late Monday into Tuesday next week
before another cold front and additional chances for showers
and thunderstorms return.

&&

.NEAR TERM /THROUGH SATURDAY NIGHT/...
400 PM update...
Main concerns in the near term are focused on the scattered
thunderstorms this afternoon into the late evening...more patchy
fog again late tonight...and another late afternoon/evening
round of showers and storms Saturday.

The air mass has destabilized once again this afternoon and
convection has initiated both along a land/sea interface near
the I-95 corridor and along a surface trough/frontal boundary
farther inland. There is an axis of 1000-2000 J/kg of ML CAPE
that is nudging westward into portions of central NY and ne PA,
and the first storm developed and grew rapidly along this
instability gradient in Pike County PA and Sullivan County NY with
some wind damage and nickel sized hail.

A Severe Thunderstorms Watch has been issued for portions of ne
PA and Sullivan County NY until 11 PM. There could be a few
more strong to severe storms that develop this evening from the
Poconos into the far southern Catskills, but the majority of the
storms will be scattered across the region and not immersed in
the higher instability which will keep the storms from mostly
becoming severe. An embedded upper short wave currently over the
mid Atlantic will lift north within the moist flow and allow
for a final push of showers and weak storms late this evening
and tapering off into the early overnight hours.

After the last batch of showers/storms tonight, there will be
the threat of some low clouds and fog into Saturday morning.
Temperatures will continue to be fairly mild with continued
humidity. The moist southerly flow will continue through
Saturday as the upper trough over the Great Lakes remains nearly
stagnant. There will likely be morning stratus continuing into
the afternoon, with some breaks and eventual cumulus clouds
bubbling up slowly through the afternoon. With no real forcing
through most of the afternoon and the axis of instability
farther to the east, the threat of showers and storms should
hold off until after 4 PM. A couple weak embedded pulses will
ride north once again through the region and act to provide the
lift within the humid/unstable air mass and trigger more showers
and and storms. Some of the storms could produce gusty winds
and heavy downpours. The threat for severe should be shunted a
little more to the east on Saturday, but cannot be ruled out
completely.

Temperatures on Saturday will warm into the mid to upper 70s
with dew points in the 60s. After sunset Sat evening
temperatures will drop back into the 60s and the boundary layer
will stabilize enough to bring most of the convection to an
end...or at least weaken the storms substantially. Some rain
showers and weak storms may continue into the overnight hours
Sat night, but the threat for impacts will be degraded.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY/...
430 pm update...

Conditions will remain unsettled with upper trough and a slow
moving surface front lingering into Monday. Shower and
thunderstorm activity will increase Sunday afternoon as a
surface low moves northeast along a southwest to northeast
running stationary boundary. Convection will continue into
Monday as the front and low slowly move east. Convection will
taper off late Monday from west to east. Deep moisture with not
much wind at low levels will increase the potential of heavy
rain and flash flooding Sunday PM.

Temperatures will vary little with highs in the 70s and lows in
the 60s.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
430 pm update...

The broad trough will transition to a deeper sharper trough as
a closed low drops into the Great Lakes Tuesday and slowly moves
to upstate NY Thursday. The trough lifts northeast Friday and
Saturday. Monday night into Tuesday will be the longest dry
period in the coming week. Isolated diurnal showers and maybe a
thunderstorm form Tuesday afternoon, but coverage increases
greatly Wednesday with a slow moving occluded surface front.
Heavy rain is likely. Thursday into Friday the trough lifts out
and chances of convection decrease from west to east.

With the upper level trough temperatures will be on the cool
side. Highs fall to the mid and upper 60s and lower 70s
Wednesday to Friday. Lows in the 50s and 60s drop to the upper
40s to mid 50s Thursday night.

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
Another round of scattered showers and thunderstorms are
expected later this afternoon and into the evening...mostly
after 22Z through 06Z. The greatest potential extends from AVP
up to BGM. After the convection moves through later tonight,
there will likely be low clouds and fog that develop and persist
into Saturday morning...through roughly 14-16Z. IFR conditions
are possible during this time with conditions improving to MVFR
after 16Z. Winds will remain mostly light and variable...and
more northerly 5 kt or less Saturday morning.

Outlook...

Saturday afternoon through Sunday...Scattered showers and
thunderstorms are expected this weekend. Convection on Saturday
looks to be mainly during the evening. Storms on Sunday appear
to initiate a little earlier in the afternoon and persist into
the evening. Brief restrictions within storms are possible,
along with restrictions on low clouds and fog.

Sunday night through Tuesday...Morning restrictions possible
from low clouds and or fog. Also, scattered showers throughout
this period but with fewer and higher restrictions.

Wednesday...A better chance of showers and storms exists by the
middle of the week with associated restrictions.
