Area Forecast Discussion
National Weather Service Binghamton NY
307 PM EDT Wed May 31 2017

.SYNOPSIS...
Scattered showers and thunderstorms will linger into this
evening before weak high pressure builds in later tonight and
Thursday to provide mostly dry weather. Scattered showers
return on Friday as the next disturbance approaches.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
240 PM Update...
An upper disturbance, coupled with marginal instability will
maintain showers and scattered thunderstorms this afternoon into
early this evening before diurnal stabilization takes over.
Best shear and instability combines over the Western Catskills,
but even that is rather marginal for severe weather. Can't
totally rule out some hail around an inch, or a gusty
thunderstorm given the inverted-v soundings as the surface
dewpoints continue to drop. Severe Thunderstorm watch will
continue for now across our 3 eastern counties. Another weak
disturbance may bring additional clouds and a chance of light
showers to the upper Mohawk Valley toward morning. Elsewhere,
moist and cool boundary layer conditions after today's rain will
promote at least some fog development, likely fairly dense in
the river valleys.

Temperatures mainly in the lower 50s with normally cold spots in
the rural areas reaching the upper 40s.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
240 PM Update...
The area remains within broad cyclonic flow aloft with weak,
and difficult to time, disturbances moving through the region.
Have included some slight chance PoPs in the better forcing
areas across the upper Mohawk Valley, Finger Lakes and Western
Catskills tomorrow, but overall confidence is low. In general,
we think this will be a mainly dry day for most areas with
varying amounts of clouds and sunshine. Temperatures roughly
5-10 degrees cooler today in the mid-60s.

More low confidence in the forecast heading into Thursday night
as weak waves continue to rotate through the region. Moisture is
limited, but the NAM and GGEM continue to hint at a possibility
of light showers, or sprinkles, across the northern half of the
area where forcing and 1000-500 mean layer RH appears to be the
highest. Again thinking this will be a fairly dry time period,
but can't rule out the possibilities for spotty light precip.
Thursday night should be rather cool under cold advection with
925 mb temps around +6-8C...which translates to the low-mid 40s
in most areas, but near 50 for parts of NEPA.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...

Northwest flow continues on Friday with a upper wave and surface
trough forecast to rotate through the area. That should trigger
a few more showers over the area. Surface high builds into the
area for Saturday As the old upper low heads east in response to
the next system dropping into the western Great Lakes.

On Sunday morning, surface low has deepened over Michigan in
response to a sharp wave dropping into the region. Rain will
break out once again as southerly flow of gulf moisture
develops ahead of the low. A good amount of rain seems possible
as the slow moving slow crawls east to near Buffalo. Dry slot
finally rotates arond the low by Monday morning but showers will
continue through the end of the period with the cold pool aloft
and deep moisture.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
Generally VFR conditions are expected into this evening with
passing showers, or a brief thunderstorm, possible at each
airport. Convection wanes early this evening. Many locations
will likely experience some fog/ceiling restrictions after
06z...with conditions improving after 12z. VFR scattered to
broken ceilings are expected on Thursday.

Winds prevailing from the SW at 5-15 knots, but variable near
thunderstorms. Winds become light tonight and return to W-SW on
Thursday.

Outlook...
Friday...Operational impacts possible. Chance SHRA/TSRA.
Saturday...No operational impacts expected. WX NIL.
Sunday-Monday...Operational impacts possible. Chance SHRA.

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