Area Forecast Discussion
National Weather Service Binghamton NY
941 PM EDT Sun Jun 30 2024

.SYNOPSIS...
Scattered lake enhanced showers are expected overnight in central
NY. Dry weather is expected Monday through Wednesday as high
pressure builds in. The chance for showers and thunderstorms
returns Wednesday night into Thursday.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...

Expanded the coverage of showers a bit into the overnight with
the late evening update given the current radar trends. Still
only a low chance of measurable rainfall over central NY.


Increased wind gusts early this evening as low level lapse rates
have steepened some across the region. Still anticipating a few
spotty showers with the incoming upper level trough this
evening.

500 PM update...

The severe thunderstorm watch across Northeast PA and Sullivan
County has been cancelled with thunderstorms exiting the area.
While thunderstorms diminish early this evening over the
southern Catskills and Northeast PA, scattered lake enhanced
showers are expected to begin developing after 00-01Z. Minor
adjustments to PoPs and temps as of the latest update.


144 PM Update...

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 overnight, with fresh
Canadian air sending lows into the lower to mid 50s for most
locations. Monday itself looks dry with pleasant temperatures
in the upper 60s-mid 70s; some post-frontal clouds initially
but eventually mixing out to mostly sunny conditions in
afternoon. We clear out Monday night in what looks like a good
radiational cooling and valley fog setup, which chilly lows of
upper 40s-mid 50s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
240 PM Update:

High pressure will be in control during most of the short term
period, which will will bring mostly sunny skies. Temperatures
on Tuesday will be at seasonable levels with highs in the upper
70s to lower 80s. With dew points in the 50s, it will also be
rather comfortable outside with relatively low humidity. The
high pressure system moves east of the area on Wednesday, which
will bring a southerly return flow and warmer temperatures
(highs in the 80s). Dew points will be on the rise as well
(rising into the lower to mid 60s). Late in the day, a frontal
system will approach the area, which may spark some isolated
showers or thunderstorms west of I-81. That being said, the
majority of the day looks dry and the majority of the shower and
thunderstorm activity will likely hold off until Wednesday
night.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
240 PM Update:

The aforementioned frontal system will push through the region
Wednesday night into Thursday, which will bring showers and
thunderstorms into the area. The front then likely stalls
somewhere in the area, which will keep shower and thunderstorm
chances in the forecast for Thursday, mainly across Northeast
PA. That being said, with uncertainty regarding where the front
stalls, Thursday`s forecast (4th of July) is rather uncertain at
this time. Another wave tracks northeast and into our region by
Friday, with more showers and thunderstorms possible. 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 lower to upper 80s with
overnight lows in the low to upper 60s.

&&

.AVIATION /02Z MONDAY THROUGH FRIDAY/...
VFR conditions are in place to start the evening as a stratus
deck continues to spread across the area from northwest to
southeast. This is associated with an upper trough that will be
pushing through the area tonight and exiting to the east during
the morning hours tomorrow. This system combined with winds out
of the north-northwest can produce spotty to scattered lake
enhanced rain showers. These showers can lower ceilings slightly
to MVFR levels beginning 04-06Z with some bouncing prior to
that across the CNY terminals. TEMPOs have been included for ITH
and BGM for potential fuel-alt ceilings during the early
morning. Ceilings will gradually improve mid-to-late morning
tomorrow as high pressure builds in and clouds scatter out.

Winds are expected to remain gusty out of the north-northwest
through the evening with gusts of 20-25 mph before easing a
little overnight. Winds are expected to increase again tomorrow
afternoon.

Outlook...

Monday night through early Tuesday morning...VFR except for
valley fog development likely for KELM.

Late Tuesday morning through Wednesday daytime...VFR.

Wednesday evening through Friday...Chances of showers and
thunderstorms with associated restrictions.
