Area Forecast Discussion
National Weather Service Binghamton NY
953 AM EDT Sun Jun 30 2024

.SYNOPSIS...
A cold front pushes through today with scattered severe
thunderstorms possible, especially in Northeast Pennsylvania and
from the Interstate 88 corridor southward in New York. Things
shift mainly east by early evening, with dry weather Monday and
Tuesday as high pressure takes over.

&&

.NEAR TERM /THROUGH MONDAY/...
950 AM Update...
Already some activity this morning with a line of
showers/storms persisting along an outflow boundary from
overnight convection. As heating continues, new cells will be
able to harness building instability and a fair amount of shear
late morning through afternoon, which has somewhat increased our
chances for scattered severe thunderstorms. The Storm Prediction
Center has placed most of Northeast PA, and counties along/south
of the I-88 Corridor into a Slight Risk. Damaging wind gusts
remain the primary threat, but isolated hail, localized heavy
rain/flooding, and even a brief tornado cannot be totally ruled
out. Convective-allowing models have been generally a few hours
behind what occurred overnight into this morning, yet still some
of them manage to generate additional clusters or line segments
this afternoon. Risk will push mainly east of our area by 6 PM.

Previous discussion...
Some of these thunderstorms cold be strong or borderline severe
this morning with localized damaging winds possible as well as
torrential downpours. Cold front moves through later this
morning and early this afternoon. Instability will have a chance
to develop mainly across NEPA and possibly Sullivan County, NY.
There is still nearly 50 knots of 0-6 km shear present, so any
storm that develops ahead or along the front in the late morning
and early afternoon could become strong to severe.

High pressure will build in behind the front tonight, however
upper trough remains overhead and some lake enhanced rain
showers will be possible across Central NY into Monday morning.
Otherwise, Monday looks mostly dry with pleasant temperatures in
the low 70s for highs.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
320 AM Update...

Surface high pressure is in control during this period with the
first half of the week staying dry. Upper level trough is slow to
move out with northwest flow remaining in place Monday night. Clear
skies and light winds will make it a favorable night for radiational
cooling allowing temperatures to fall into the upper 40s to low 50s.
Upper level ridge moves in on Tuesday with surface high centering
over our region. Southerly flow returns with temperatures climbing
into the upper 70s to the low 80s during the day. Temperatures are
more mild overnight with lows ranging in the low to mid 60s with a
pocket of mid 50s over the Western Catskills region.

&&

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

Upper level ridge with southerly flow holds for one more day keeping
temperatures warm on Wednesday with highs in the low to upper 80s.
High pressure slides to the east Wednesday with a system over the
midwest starting to approach our region by the evening. This kicks
off showers and thunderstorms that will continue into Thursday.
Thursday is a bit up in the air in terms of precip chances depending
on how far south the front can push before stalling out.
Another wave tracks northeast and into our region by Friday, with
more showers and thunderstorms. Models begin to diverge for the rest
of the period, therefore relied on NBM Pops through Sunday.
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 /14Z SUNDAY THROUGH THURSDAY/...
Cold front pushes through the region this morning through this
afternoon with restrictions likely in showers and possibly a
thunderstorm, especially KAVP. Conditions gradually improve to
VFR later this afternoon. However, low stratus behind the front
will likely produce some MVFR ceilings overnight and into Monday
morning.

Outlook...

Monday through Wednesday...Mainly VFR.

Wednesday night into Thursday...Restrictions with showers and
thunderstorms possible.
