AREA FORECAST DISCUSSION
National Weather Service Albany NY
350 AM EDT Sat Jun 8 2024

.SYNOPSIS...
An upper level low pressure system will keep clouds across the
region today, along with isolated to scattered showers,
especially for areas north of Interstate 90. It will also be
breezy at times. A compact area of low pressure will bring a
period of rain late tonight through Sunday morning, tapering to
scattered showers Sunday afternoon. Cooler than normal
temperatures and a few showers will continue into early next
week as an upper level trough remains nearby.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 345 AM EDT, an upper level low across eastern Canada
continues to influence our weather, with an embedded disturbance
currently tracking across the SW Adirondacks producing
scattered showers. Some of these showers will expand east into
the upper Hudson Valley and southern VT through mid morning, and
could extend into the Mohawk Valley and northern portions of
the Capital Region at times.

The upper level low will pivot northward this afternoon,
allowing for some gradual height rises. This should allow for
decreasing coverage of showers from south to north this
afternoon, with a few breaks of sun possibly developing,
particularly in valley areas.

Deeper mixing this afternoon should allow west to northwest
winds to become quite gusty, with gusts of 25-35 mph developing
by mid to late afternoon as mixing depth increases. A few gusts
up to 40 mph could occur near and immediately north of the
Mohawk Valley/Capital Region and Berkshires, especially should
any breaks of sun develop.

Afternoon max temps should reach the lower/mid 70s in valley
areas, with mainly 60s across higher elevations.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
Weak low/mid level ridging will translate across the region
this evening, ahead of a strong upper level disturbance
approaching from the west. This should allow for a period of
generally dry weather early this evening. However, rain should
then expand eastward across the region after midnight as the
disturbance and developing compact low pressure system approach.
A period of steady light to moderate rain is possible prior to
daybreak, especially for areas close to and just north of the
I-90 corridor. Low temperatures mainly in the 50s.

Periods of rain are expected Sunday morning as the upper level
disturbance and compact low pressure system move across the
region. As these systems track east of the region, rain should
taper to scattered showers in the afternoon. Cold air aloft
along with a lingering upper level trough may provide enough
instability for isolated low-topped thunderstorms to occur,
especially areas north of I-90. Small hail and gusty winds could
occur should any thunderstorms develop. Afternoon high
temperatures should reach the lower/mid 70s in valleys, and
65-70 across higher terrain areas. West to northwest winds may
become gusty once again Sunday afternoon, although a bit less in
magnitude compared to today, perhaps reaching 25-30 mph.

Scattered showers should gradually decrease in coverage Sunday
night, although may persist across portions of the SW
Adirondacks in closer proximity some lake enhancement. Otherwise
it will be rather cool with low temperatures in the upper 40s to
lower/mid 50s.

Upper level trough will pivot southeast across the region Monday
into Monday night, bringing more clouds and isolated to
scattered rain showers, especially Monday afternoon. It will
remain cool, with highs in the 60s for most higher elevations,
and lower/mid 70s for valleys. Lows Monday night in the mid 40s
to lower 50s.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
While upper level ridging won`t be too far away (building north/east
across the Great Lakes), the Northeast is still expected to be under
an elongated upper level trough through Tue. Forcing looks to be
limited, so will only mention a slight chance of diurnally driven
showers in the afternoon to early evening. Temperatures will not be
quite as cool as prior days, with highs in the mid 70s for most
valley locations.

The upper level trough finally exits on Wed, with short wave upper
level ridging building east into the area. This will result in dry
conditions and temperatures warning to slightly above normal levels.
On Thu, heights aloft are forecast to flatten out as the flow regime
W-NW, but with a warmer air mass in place. A weak disturbance
embedded in the fast flow aloft could produce some showers/T-storms.
Moisture/forcing look limited, so will just mention isolated
coverage for now.

A more substantial upper level trough and associated surface cold
front are expected to move into the region on Fri, with a better
chance for showers and T-storms. W-SW winds are forecast to
strengthen ahead of the trough/front, so should sufficient
instability develop, will have to monitor for some potentially
stronger storms. Temperatures should continue to be above
normal.

.AVIATION /08Z SATURDAY THROUGH WEDNESDAY/...
Through 06z Sunday...An upper level low will move across the
region through early this afternoon. Initially, clouds have
scoured from around KALB-KPOU but will re-develop early this
morning from NW to SE. BKN cigs at KGFL/KPSF should remain, with
borderline MVFR/VFR cigs at KPSF. All other sites through remain
VFR through 12z today. Then, widely scattered showers will move
across the area, mainly along and especially north of I-90. So
have included VCSH and/or PROB30 at KALB/KGFL/KPSF from around
12z through 18z. Brief MVFR conditions will be possible within
any SHRA, but cigs may tend more towards prevailing MVFR levels
at KPSF.

Scattered SHRA should end after 18z, with drying conditions and
clouds gradually decreasing through the rest of the afternoon
with short wave ridging building in behind the upper low. VFR
conditions are then expected to prevail through the rest of the
TAF period ending 06z Sun with just FEW-SCT mid level clouds.

Winds will initially be west-southwest around 3-7 kt, becoming
westerly and steadily increasing to 10-17 kt with gusts of
20-30 kt developing by early afternoon.

Outlook...

Sunday Night: No Operational Impact. NO SIG WX.
Monday: Moderate Operational Impact. Scattered SHRA.
Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Low Operational Impact. Slight Chance of SHRA.
Tuesday Night: No Operational Impact. NO SIG WX.
Wednesday: No Operational Impact. NO SIG WX.
