Area Forecast Discussion
National Weather Service Binghamton NY
948 AM EDT Thu Jul 13 2017

.SYNOPSIS...
A slow moving front hanging across NY and PA will keep showers
and thunderstorms in the forecast through Friday. Some of these
storms will be strong with very heavy rain and gusty winds.
&&

.NEAR TERM /THROUGH TONIGHT/...

935 AM Update...No major changes to forecast thinking. The area
is in a lull however more showers and storms are still on track
to move in late morning and continue this afternoon into early
this evening. Minor updates to POP/QPF/T grids based on latest
conditions.

350 AM update...

We extended the flash flood watch until 00z Friday and raised
temperatures for early this morning.

230 AM update...

A persistent frontal boundary strung across our forecast area
will continue to produce showers and thunderstorms through
tonight.

A relative lull in the action is forecast through mid-morning
before another wave of energy moving into NY/PA combines with
diurnal instability to increase activity during the afternoon
hours.

Warm mid-levels and weak lapse rates will be a limiting factor
for thunderstorm intensity. However, 30 to 40 knot mid-level
flow supports the potential for gusty winds in stronger cells.

With high PWAT values in place (close to 2 inches), heavy rain
will be the main threat with thunderstorms.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
A cold front will push into Western NY on Friday. An additional
round of showers and thunderstorms is forecast to develop over
NY and PA, especially when another short wave drops into
northern NY late Friday.

As the front moves east into New England, activity will diminish
Friday night.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
330 am update...

Relatively quiet weather conditions this weekend as one system exits
to the east early Saturday and the next short wave drops in from the
nw later in the day Sunday.

The large scale cyclonic flow will continue this weekend with an
embedded s/w exiting to the east early on Saturday with associated
rain showers ending west to east in the morning. Most areas should
remain dry through the rest of the day, but given the active flow
and the weak destabilization in the afternoon/evening, a few
isolated showers and weak storms are possible. Available moisture
will be limited and most of the weak convection should stabilize
after sunset...so not expecting any significant storms or
rainfall.

Weak ridging aloft will keep conditions quiet Saturday night and
most of Sunday morning. However the next s/w will drop in from the
nw through the Great Lakes Sunday morning and reach NY/PA by the
late afternoon/evening time frame. Will see the initial band of
showers and storms during this time, with more precipitation into
the night.

Temperatures will remain seasonable with highs in the upper 70s and
lower 80s...and overnight lows in the upper 50s and 60s.

Monday through Wednesday...Upper low will track e/sewd through
the region Sunday night into Monday and linger just off the NJ
coast into Tuesday with rain showers and thunderstorms possible
over central NY and ne PA during this time. Periods of heavy
rain are possible Sunday night and again Monday night, with only
light rain expected Tuesday. Heights aloft will rise behind the
departing system on Wednesday with dry weather expected.
Temperatures remain steady with highs in the 70s and 80s...and
night time lows in the 60s.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
Thunderstorms will redevelop across the terminals between early
and mid-afternoon. Ceilings today will fluctuate between 1500
and 5000 feet, while visibilities will drop to between 2SM and
4SM in heavy downpours.

Low stratus is likely to develop Thursday night.

Outlook...

Thursday night to Friday night...Showers and thunderstorms with
associated restrictions.

Saturday to Sunday...mainly VFR.

Monday...some restrictions with showers and thunderstorms.

&&

.BGM WATCHES/WARNINGS/ADVISORIES...
PA...None.
