150 pm edt Thu aug 22 2019

Synopsis
.A cold front will cross the area today, bringing isolated to
scattered showers, mainly to areas south and east of albany. A
wave of low pressure tracking along the front will bring some
showers to areas mainly south of albany again tonight. Drier,
cooler and less humid conditions are expected for Friday into
Saturday as high pressure builds into the region.

Near term until 6 pm this evening
As of 150 pm edt... A few showers have developed across the
catskills, just west of ulster county early this afternoon along
the surface cold front pushing southeastward. There is some
instability present, with around 500-1000 j kg of SBCAPE from
the catskills eastward through the mid hudson valley, southern
taconics and NW ct. This is where a few thunderstorms may occur
just ahead of the front. Elsewhere, just isolated to widely
scattered showers are expected with the frontal passage. A few
storms may produce gusty winds in dutchess litchfield counties.

The cold front should continue slowly tracking south and east
across the central part of the area. Winds have shifted to the
nw at kalb, although dewpoints are still in the mid 60s.

Dewpoints are lower to the west, and are in the upper 50s in
the mohawk valley. MAX temps should reach the lower mid 80s in
many valley areas today, with some upper 80s possible across the
mid hudson valley and lower elevations in NW ct where
downsloping NW winds may enhance warming potential.

Dewpoints should fall into the 50s for many areas by late
afternoon, except remaining in the 60s for the capital region
and points south and east.

Short term 6 pm this evening through Saturday night
Tonight, the front should track southeast of the region early
tonight, however a wave of low pressure is expected to ripple
along the front in response to a sharpening shortwave tracking
southeast from the western great lakes, along with the right
entrance region of an upper level jet translating across ontario
and western quebec. Backing mid upper level flow should allow
clouds and showers to expand northeast into the SE catskills,
mid hudson valley southern taconics, NW ct and central southern
berkshires this evening and overnight. It is possible that the
northern edge of these showers expands as far north and west as
the i-90 i-88 corridors. Some pockets of moderate rain could
occur in southern areas. Meanwhile, northern areas should remain
clear to partly cloudy as high pressure builds in. Lows mainly
in the 50s to lower 60s, except for some 40s across the
southwest adirondacks.

Friday-Friday night, some lingering clouds and perhaps spotty
showers across southeast areas early in the morning, followed by
partly to mostly sunny skies by afternoon. There is a low
probability that some light showers sprinkles could develop in
the afternoon as the main upper level trough cold pool passes
through, but will keep out mention at this time given forecast
moisture profiles suggesting a rather deep layer of dry mid
level air advecting into the region. It will be cooler and much
less humid, with highs mostly in the 70s for valley areas, and
60s higher terrain areas. Rather cool for Friday night with
clear to partly cloudy skies, with lows in the upper 40s to mid
50s, except some lower 40s across portions of the SW adirondacks
and southern vt.

Saturday-Saturday night, high pressure continues to build in
from the north, however some upper level energy may gradually
pass southward across the region later Saturday into Saturday
night. This may allow for some clouds to develop, and could even
see a couple of showers across mainly higher terrain areas
Saturday afternoon. Highs Saturday mainly in the 70s for
valleys, 60s higher elevations. Lows Saturday night in the 40s
and 50s.

Long term Sunday through Wednesday
Sunday, GFS and increasing amount of GEFS members coming in line
with the ECMWF in lingering a cutoff low over the region. Pwat will
be fairly low at less than an inch, but cannot rule out a few
diurnal showers with a 500 mb cold pocket overhead. Went with some
low chance pops mainly south of i-90.

Though upper lows can be stubborn, consensus is for the low to shift
northeastward and become replaced by a narrow ridge for Monday-
Tuesday, resulting in dry conditions. Temperatures Sunday-Tuesday
will likely be a bit on the cool side of normal with easterly flow
draining from high pressure over the canadian maritimes.

Indications are for the ridge to shift eastward by Tuesday
night Wednesday as a broad trough approaches from the western great
lakes. Return flow in advance of this feature should boost temps
back up near normal values, but showers may spread into the region
as the trough impinges.

Aviation 18z Thursday through Tuesday
Vfr are expected to prevail much of the time across the taf
sites through the next 24 hours ending 18z Friday. The only
exception may be for brief MVFR ifr conditions at kpou this
evening associated with scattered showers isolated
thunderstorms along a cold front. Will only mention tempo for
shra at this time, since coverage of thunder is expected to be
sparse.

Otherwise, drier air will gradually build into much of region
tonight with n-nw flow inhibiting fog formation. A few more
showers will be possible, especially at kpou and possibly kpsf,
associated with a weak wave of low pressure developing along
the cold front as it passes just south of the area.

Winds through today will be west-northwest around 10 kt,
becoming northwest around 5 kt tonight. Winds on Friday will be
north-northwest around 10 kt.

Outlook...

Friday: no operational impact. No sig wx.

Friday night: no operational impact. No sig wx.

Saturday: no operational impact. No sig wx.

Saturday night: no operational impact. No sig wx.

Sunday: low operational impact. Slight chance of shra.

Sunday night: no operational impact. No sig wx.

Monday: no operational impact. No sig wx.

Fire weather
A cold front will cross the area today, bringing isolated to
scattered showers. Isolated thunderstorms will be possible
across the mid hudson valley and NW ct. A wave of low pressure
tracking along the front will bring showers to areas mainly
south of albany tonight. Drier, cooler and less humid conditions
are expected for Friday into Saturday as high pressure builds
into the region.

Rh values will decrease to minimum values of around 45 to 55
percent this afternoon, and increase to 85 to 100 percent
tonight with areas of dew formation likely. Rh should drop to
around 45-55 percent Friday afternoon.

South to southwest winds at around 5 mph will become west to
northwest and increase to 5 to 15 mph this afternoon, then
decrease to around 5 mph tonight.

Hydrology
Scattered showers and isolated thunderstorms are possible
today into tonight, mainly for areas south of albany. Most of
this activity will be light, but brief downpours will be
possible in any thunderstorms.

Dry conditions are expected Friday into Saturday.

Isolated showers will be possible Sunday.

and forecast river stages and lake elevations, please visit the

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
