.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
.UPDATE...As 1245 PM EDT...The ongoing forecast is in good
shape.

The short-wave and low pressure system continues to move
northeast across eastern New England. The rainfall has ended
across the western New England zones in the WFO ALY forecast
area. Some clouds linger with partly to mostly sunny skies west
of the Taconics/western England. The upper level trough axis
still lingers upstream. The north/northwest winds have increased
to 10-15 mph with some gusts 20-25 mph with funneling down the
Champlain and Hudson River Valleys. We increased the winds,
removed the PoPs and retooled the sky cover based on the GOES-16
visible satellite imagery and observations. A couple isolated
showers are possible over the Berkshires, Litchfield Hills, and
easter Catskills in the late afternoon. Temps will run a little
below normal for late May with upper 60s and lower 70s below
1000 ft elevation with upper 50s to mid 60s over the higher
terrain with breezy conditions.


.PREV DISCUSSION [0345 AM EDT]...

As the potent shortwave and associated surface low exit to the
east through the day today, rain showers will end in southeastern
areas by mid-morning, with skies expected to trend clearer as
heights aloft begin to rise by tonight. A few rain showers may
develop over the Berkshires and eastern Catskills following peak
diurnal heating with cooler air aloft. Following morning lows
in the 40s to low 50s for most and upper 30s in the southern
Adirondacks, temperatures will remain slightly below normal
beneath the cold pool within upper troughing and a cool
northerly to northwesterly breeze. Afternoon highs are expected
in the upper 50s to mid 60s in high terrain, and upper 60s to
low 70s at lower elevations. With diminishing winds and clearing
skies overnight tonight, efficient radiative cooling will allow
temperatures to fall to low in the upper 30s to mid 40s across
the region.

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Narrow but high amplitude upper ridging and associated surface
high pressure will build in from the west Friday into the
weekend, bringing continued dry weather and mostly sunny skies.
Temperatures trend upward through the period as northwesterly
flow on Friday begins to turn out of the southwest on Saturday.
Afternoon highs will be near normal on Friday, with 60s in high
terrain and low to mid 70s at lower elevations, and will reach
above normal on Saturday, with widespread 70s, a few upper 60s
in areas of highest terrain, and a few low 80s along the Hudson
River. Overnight lows similarly trend warmer with 40s expected
across the region Friday night and upper 40s to mid 50s on
Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The upper level ridge looks to break down heading into the second
half of the weekend as an upper-level shortwave passes nearby or
just to our south. This shortwave looks a bit stronger compared to
recent runs and may contain enough moisture for an isolated shower
or thunderstorm, especially for areas west of the Hudson River.
Otherwise, it should remain a fairly seasonable day with comfortable
humidity levels. Highs should reach the 70s in most areas with some
valley locations around 80.

The upper-level pattern becomes a bit uncertain for early to mid
next week, but upper level ridging attempts to return across the
region with surface high pressure nearby or just off the East Coast.
Warmer and more humid conditions build across the region with the
potential for some pop up showers and thunderstorms on some days.
Coverage and best timing of these showers remains a bit uncertain
but no day looks to be a washout. Highs Monday through Wednesday
look to range from the mid-70s to mid-80s with lows in the mid-50s
to lower 60s.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Through 12z/Fri...Rain will end at KPOU/KPSF by 13z/Thu with drier
weather for the rest of the TAF cycle. MVFR cigs/vsbys at KPOU/KPSF
will lift to VFR after rain ends. VFR conditions will continue at
KALB/KGFL. Cloudy/mostly cloudy conditions early this morning will
trend mostly clear this afternoon through tonight. With the drier
air mass advecting into the region, no fog is expected tonight.

Wind will become north to northwesterly at all sites through the
afternoon at speeds around 10 kt with a few higher gusts. Wind will
trend light to calm tonight.

Outlook...

Thursday Night to Monday: No Operational Impact. NO SIG WX.

&&

.FIRE WEATHER...
Today, a dry airmass and deep mixing will result in surface
dewpoints falling to the mid 30s to mid 40s across the region,
while temperatures in the 60s to low 70s will lead to minimum RH
values around 30 to 40 percent. Northerly winds of 5 to 10 knots
will gust to around 15 knots. Widespread rainfall of at least a
half inch earlier this week, with many observations of one to
three inches in areas of higher terrain, will be supplemented by
an additional soaking rainfall south and east of Albany early
this morning, acting to limit the risk of fire spread.
Therefore, Special Weather Statements for enhanced fire spread
are not being considered.

Friday may again feature marginal conditions for fire spread,
with minimum RH values of 30 to 40 percent and northwesterly
wind gusts of 15 t0 20 knots, however the recent rainfall will
again limit fire weather concerns.
