Area Forecast Discussion
National Weather Service Binghamton NY
338 PM EDT MON JUL 25 2016

.SYNOPSIS...
Today will be very warm and muggy with showers and thunderstorms.
A few thunderstorms could have damaging winds and heavy rain. A
cold front will move across the area this evening and end the
showers. This front will also bring drier air and quiet weather
for Tuesday and Wednesday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
3 PM update...

severe thunderstorm watch now in effect until 8 PM. Strong
thunderstorms moving east across south central NY and northeast PA
attm. This convection will continue to move southeast and clear
the CWA by 6 PM. Some models have some showers behind this and
ahead of the cold front. Will be very little with the atmosphere
worked over and temperatures in the 70s.

For now dewpoints have risen to around 70 behind the warm front.
Temperatures rebounded into the 80s before this current batch came
pushing Cape over 1k Joules.

Late tonight dry with clearing skies and light winds. With this
rain valley fog likely across south central NY and ne PA. Boundary
layer winds drop to 10 to 15 kts. Low temps in the 60s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
3 PM Update...

High pressure over the Midwest will build east over our region
Tuesday and last through Wednesday. Dry air returns with partly
cloudy to clear skies. Highs mostly in the 80s with lows upper 50s
to mid 60s.

Thursday the high moves east into New England while moisture
returns. A weak upper level trough and short wave drops towards
the CWA. Most of the showers and thunderstorms will most likely be
in the afternoon.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
For Thursday night and Friday, the EURO, GFS and CMC all indicate
a surface wave associated with an upper level short wave impacting
NY and PA. The EURO and CMC are most aggressive and have a nice
shot of rain for our drought stricken areas in central NY. The GFS
is much farther south and east and drier. For now went with
superblend POPs for these time periods. Then for Friday through
Sunday models diverge with the EURO showing the best potential for
showers and thunderstorms holding the main upper level wave back
to the west with a more well defined moist southerly flow into
the weekend over our area. The GFS and CMC show a weaker upper short
wave to the west of our area and less organized convective
potential. So for now have 30-40 chance POPS through the weekend
as per superblend.

Leaned heavily on superblend and collaborated grids with
neighboring WFOs for this period.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
First batch of convection exiting the region with some convection
close to KAVP. Have a tempo group to cover this between 18 and
19z at KAVP. Otherwise rest of terminals start off convection
free as the next batch of showers and storms approaches. I have
timed a potential line of storms to race across the region between
19z and 23z with KELM and KSYR earliest and KAVP latest. In our
northern terminals away from the higher instability have MVFR in
TSRA, farther south have IFR in +TSRA with gusty winds mainly
between 19z and 21z, except until 23z at KAVP.

Then after storms passes expect VFR most of the night and Tuesday
am except at KELM. With the rains and wet ground we expect valley
fog later tonight at KELM and have LIFR between 9 and 13z in a
tempo group.

Winds will be W-SW 5 to 10 knots and gusty into this evening,
light westerly overnight and W-NW 5 to 12 knots on Tuesday
morning.

OUTLOOK...

Tue pm to Wed night...mainly VFR.

Thu-Sat...showers and thunderstorms. Mostly VFR to MVFR.
