Area Forecast Discussion
National Weather Service Binghamton NY
254 AM EDT Sat Jun 29 2024

.SYNOPSIS...
Periods of showers and thunderstorms are expected today and
tonight. Showers and storms linger into Sunday as cold front
pushes through. Drier air returns Monday and lasts through
midweek under high pressure.

&&

.NEAR TERM /THROUGH SUNDAY/...
245 AM Update...

Deep SW flow will increase moisture across the region today with
a strong low- level jet pushing into the area this evening and
tonight ahead of a cold front. For today, PWATs increase to near
2" by early this afternoon. Instability is weak today and
through the afternoon, so current thinking is mostly rain
showers through the day. However, later tonight as the low level
jet punches in, instability and shear increase. Main concern for
this evening and tonight is the strong low level shear and
impressive helicity. A high shear, and low instability
environment may still be enough to support a brief tornado and
strong wind gusts in a low topped convective environment.
Localized flash flooding will also be possible with high PWATs
and deep warm cloud layer, and any thunderstorms that are able
to materialize will be efficient rain makers.

Cold front enters our western counties Sunday morning and pushes
across the area. More showers and thunderstorms will be likely
depending of FROPA timing. Best chances for anything severe will
be our far east/south eastern counties.

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
300 AM Update...

Upper level trough lags behind cold front that went through the
region earlier on Sunday. This could keep a few showers going
into Sunday night with the potential for some of these showers
to be lake enhanced. Northwest flow and cooler temperatures
settle in behind the front with lows falling into the low to mid
50s across the region. Shower chances diminish by Monday
morning as drier air moves in with high pressure building over
the midwest. Temperatures will also be cooler with northwest
flow in place. Highs will reach the low to mid 70s with
overnight lows in the upper 40s to low 50s. High pressure
centers over our region on Tuesday with calm and dry conditions
continuing. Winds shift to the south allowing temperatures to
warm back up into the upper 70s to low 80s. Overnight lows are
more mild as well with temperatures in the low to mid 60s, with
some pockets of upper 50s.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
300 AM Update...

Upper level ridge remains in place for most of Wednesday with high
pressure sliding east keeping conditions precip free. According to
GFS & Canadian NH another system approaches the region Wednesday
night into Thursday with showers and possible thunderstorms moving
through. Euro has a different resolution with showers staying south
of our region which would be a more favorable outcome for
Independence day. Models begin to diverge for the rest of the
period, therefore relied on NBM Pops through Saturday.
Temperatures during this time frame will be warm with highs
ranging in the low to upper 80s with overnight lows in the low
to upper 60s.

&&

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Warm front will bring light rain showers into the region this
morning. These showers may bring brief MVFR restrictions.
Heavier showers and thunderstorms move into the area this
afternoon and evening, which will reduce visibilities and
ceilings.

Southerly winds will become gusty this morning with gusts as
high as 20 kts. Tomorrow, as the system moves in with the
showers, gusts will be 20 to 25 kts through the afternoon and
early evening hours. Low-level wind shear (LLWS) will be
possible, but with thunderstorms also becoming more likely late
in the day, decided not to add LLWS to any sites except RME.
Direction will be south- southwest with speeds up to 40 kts at
2000 ft AGL.

Outlook...


Sunday...Restrictions from showers and thunderstorms possible.


Monday through Wednesday...Mainly VFR.
