area forecast discussion
national weather service binghamton ny
947 am edt Thu may 25 2017

Synopsis
A large low pressure system will spread rain over the area
this morning, with at least scattered showers continuing this
afternoon through Friday. Though rather cool the next couple of
days, temperatures will trend slightly warmer over the weekend.

Mainly dry conditions are expected Saturday. This will be
followed by increasing chances for showers Sunday into Monday.

Near term through tonight
930 am edt update...

light rain showers are moving north across the region this
morning around 20-25 mph. The sfc low is located over ohio
valley and will drift NE today and showers will continue to
drift to the ne. The dry slot is slowly pushing into central
pa, thus steadier rain across the region should end late this
am, or early afternoon. Scattered activity is expected to follow
after the drier air moves into the region. Overall, the
previous forecast is in great shape and only minor adjustments
were made to the forecast. For more information, please read the
previous forecast discussion below.

Previous forecast discussion...

655 am update... Left exit region of 300mb jet continues to
develop rain throughout central-western pa into western ny, and
as expected, rest of wave is moving into the rest of the region
now. Some apparent wind shadowing is occurring up the i-81
corridor, which will help realize the anticipated lower rainfall
amounts compared to point east and west, as described below.

Previous discussion...

wet and chilly conditions are expected in the near term. Clouds
are thickening and lowering with time, in moistening southerly
flow aloft ahead of stacked low pressure centered in the mid-
ohio valley region. Upper level divergence, and an incoming wave
with deep moisture, will bring a steady rain into the region
this morning. Some light showers have already started out of a
mid-deck in western ny, but the main wave is now in central to
southeast pa and inbound. Shield of light to moderate rain will
spread rain across northeast pa and part of the finger lakes
prior to dawn, then the remainder of the area later this
morning. Rain will be aided by east- southeast low level jet
infusing atlantic moisture, and forced ascent of left exit
region of 300mb jet aloft. By noon, the main wave of rain will
have lifted out of northeast pa, and through central ny by about
3pm. In the wake of the main wave, dry slotting occurs and thus
only scattered low topped showers will continue mid afternoon
to early evening.

Later this evening through tonight, the stacked low will pass
directly over the region, including pocket of chilly air aloft.

This will introduce enough elevated instability via steeper mid
level lapse rates for embedded thunder to be possible. Best
likelihood for additional showers and possible thunder will be
all of northeast pa, and in central ny mainly east of i-81. At
least scattered showers can be expected elsewhere.

Temperatures will move little from readings this morning, with
highs stuck in upper 50s-lower 60s. With abundant clouds and
low pressure passing overhead tonight, very little drop in
temperatures with lows in the lower-mid 50s.

Adding up the morning to midday wave, the secondary activity
from the low passage tonight, and the scattered showers in
between; we are figuring on average rain amounts of half to
three-quarters of an inch. It appears that the maxima of
rainfall will be divided to steuben-yates counties in the west
and poconos-catskills in the east, where localized amounts up to
an inch will be possible. This will not be enough to cause
flooding problems. Also, with any thunder being derived from
marginal instability aloft this evening-tonight, strong
thunderstorms are not expected to impact the area.

Short term Friday through Saturday night
230 am update...

vertically stacked low off the new england coast Friday morning
will slowly move east during the day allowing high pressure to
build in. This will lower the chance of showers during the
afternoon across the forecast area as drier air returns.

Ridging aloft and at the surface will keep the area dry on
Saturday with near normal temperatures.

Previous discussion continues below.

220 pm edt update...

by Friday morning the stacked low will be east of the region
and a few showers will be lingering over the region as NW flow
will prevail over the region. This system will have minimal caa
with it as heights will quickly build back behind this system.

By Friday evening the mid and uppr-lvl ridge will start to
build into the region. The NW flow should keep an inversion in
place throughout the afternoon keeping mostly cloudy skies over
the region, thus sfc temps will stay in the low to mid 60s
across much of the area. Nepa may reach the uppr 60s.

By Sat morning the ridge will continue to build eastward and heights
will continue to build over the region. Sfc temps will easily be
able to rebound into the mid to upper 70s on sat. A wave embedded
within the outer edge of the ridge will slide across the region on
sat. This may create a few showers over nepa and central ny.

Long term Sunday through Wednesday
230 am update...

tweaked some of the pops to better match the latest guidance
for speed and location, and better align with the surrounding
offices. Minor temperature adjustments made as well. No other
changes made. Previous discussion continues below.

220 pm edt update...

minor chances were made to the previous forecast.

The weather during this period continues to look active as the next
storm system to move into to the region will start to slide
into the great lakes region on Sunday. This next stacked low
looks like it will remain semi-stationary through Wednesday and
create the chance for rain showers each day of the extended
forecast through Wednesday evening. The trend for a wet spring
continues.

Temps during the forecast period will be at or slightly above the
seasonal norm.

Aviation 14z Thursday through Monday
Low pressure system is causing development of rain and
deteriorating conditions. Initial showers were without
restrictions, but as further moistening occurs, steadier rain
is lowering ceilings from south to north which bringing a
progression into MVFR conditions and eventual fuel alternate
required levels. Kavp-kelm-krme will also keep marginal low
level wind shear for a time. In wake of main wave of rain,
ceiling restrictions will persist but showers will be scattered.

Ifr ceilings are expected by evening for kavp-kbgm-kelm-kith,
though there is some uncertainty as to whether kbgm-kavp could
start it earlier. There is a small chance of embedded thunder at
kbgm-kavp this evening as well; not enough confidence to
include in tafs but something to be aware of. Winds will be
east or southeast increasing to 7-14 knots, then becoming light
and variable tonight as low pressure moves overhead.

Outlook...

Friday through Friday night... Scattered showers with associated
restrictions, especially Friday, as low pressure system exits.

Saturday through early Sunday... MainlyVFR.

Midday Sunday through Monday... Showers and restrictions likely.

Some thunder also possible.

Bgm watches warnings advisories
Pa... None.

Ny... None.
