Area Forecast Discussion
National Weather Service Binghamton NY
350 PM EDT Fri Jun 30 2017

.SYNOPSIS...
There will be increasing chances for showers and thunderstorms
today through Saturday as multiple disturbances pass through the
region, followed by a strong cold front. Some storms could
contain gusty winds, hail, and locally heavy rainfall. The
weather pattern should finally quiet down into early next week
courtesy of high pressure.

&&

.NEAR TERM /THROUGH SATURDAY NIGHT/...
Two broken lines of showers and thunderstorms are moving across
the area through 3 pm. The first line extends from the Catskills
southwest to northeast Pa with a second, shorter line over the
northern Finger Lakes. The first line has featured several
storms with strong reflectivity cores up to between 15 and 20
kft and with rotational signatures in velocity and
reflectivity, however all of the cores with these storms appear
to be limited to levels below 25000 feet. An ACARS soundings
from the local area appear to be showing weak lapse rates in the
layer above 20 kft and perhaps this is the reason that storms
have struggled to get deep enough to produce large hail or
damaging winds so far. We are keeping the watch going for
awhile along and east of I-81 but unless the storms can find a
way to intensify late this afternoon an early cancellation is
possible. These storms will be out of the area later this
evening.

After a break in the weather, another round of showers and
thunderstorms appears likely on Saturday, mainly during the
afternoon into the evening as a cold front moves across the
area. Once again mid-level wind fields will be easily strong
enough for severe weather with deep layer shear values at or
above 40 kt. The question will once again be the CAPE, the NAM
is advertising values well over 1000 J/kg, while the GFS shows
values from 500 J/kg to 1000 J/kg. Unlike today, the upper jet
dynamical pattern looks more favorable for large-scale lifting
with the area in the right entrance region of the upper jet,
while a significant trough advances toward the area from the
Great Lakes along with an associated surface cold front. Once
again the SPC has our area in a slight risk for severe weather
and we will need to monitor the situation as several factors
appear to be at least reasonably favorable. Locally heavy rain
will also be possible with pwat values between 1.5 and 2.0
inches.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY/...
320 pm update...
Main concerns in the short term remain focused around the ending
showers and storms Saturday evening/night west to east...lingering
showers into Sunday and quiet/cooler weather on Monday.

Cold front will be lifting newd Saturday evening with trailing
showers and storms exiting the region to the east. The air mass will
likely be becoming more stable through the overnight hours, and
allow the thunderstorms to transition to mainly rain showers. Deep
cyclonic flow will settle in over the region behind the front with a
cooler air mass moving in. This pattern will be conducive for
isolated popup showers into Sunday, with some destabilization in the
afternoon over the Finger Lakes and potentially a few weak storms.
Deep layer moisture will be very limited...along with instability
and shear.

A much drier air mass arrives on Monday with high pressure at the
surface starting to build in from the west. Will see more sun on
Monday but the temperatures will be noticeably cooler...only rising
into the 70s to around 80.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
320 pm update...
Main concerns in the long term are focused around cool/dry air mass
to begin with and the development of more showers and storms late
Wednesday into Thursday.

High pressure dominates the region on Independence Day with weak
ridging aloft. Will start to see a gradual warm up into the middle
of the week with widespread highs into the lower 80s by Wednesday.
The surface high shifts to the east Wednesday with a return sly flow
helping to heat things up a bit. This will also help set up the
atmosphere for additional showers and storms late Wed and Thursday
as an area of low pressure moves ewd across Pennsylvania. Will need
to watch this system through the next several days as it appears to
be capable of tapping into a deep moisture source and be fairly
dynamic...so there may be a hydro concern later next week.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
Showers and thunderstorms will move across the area this
afternoon into early this evening. We have this covered in the
TAFs at all locations with a TEMPO group for MVFR conditions
with a thunderstorm until around 22z. Storms will be mainly
east of the area by mid-evening with VFR conditions through most
of the night followed by areas of MVFR with lower clouds and
patchy light fog between 08z and 14z Saturday. A return to
primarily VFR conditions is expected late Saturday morning into
the afternoon. Another round of showers and thunderstorms will
move across the area Saturday afternoon into the evening.

Outlook...

Saturday morning through Saturday evening...Restrictions likely
in showers/thunderstorms as front moves through area.

Late Saturday night through Sunday...Mainly VFR but still a
small chance for showers-thunder and associated restrictions.

Sunday night through Tuesday...Quieter weather but with a
small chance of afternoon showers and associated restrictions.
