Synopsis
Cooler and less humid weather will continue through the weekend
into early next week as high pressure dominates.

Near term through Saturday
As of 8 pm... High pressure at the surface centered over the
great lakes region this evening will shift eastward across
eastern canada through Saturday. While aloft region will be
under a weakening trough. Looking at fair weather with slightly
below normal temperatures. Lows tonight from the lower 40s to
mid 50s with highs Saturday in the 70s with 60s above 1000 feet.

Some patchy fog is expected to develop late at night in
favorable locations which will lift and burn off quickly after
sunrise. Winds will be light and from the north to northeast.

Short term Saturday night through Sunday night
Skies will remain partly cloudy for awhile from the capital
district south as the band of mid and high level cloudiness
slowly recedes to the south. Meanwhile, skies will clear quickly
across the north with the loss of heating and associated cu.

Much of the area will be clear later tonight with areas of fog
developing after midnight, especially in the river valleys.

Tonight will be the coolest night that we have had for awhile as
lows reach the 40s across the north country with lower to mid
50s in most areas from the capital district southward.

Quiet, pleasant late summer weather looks to be in the forecast
for the next few days. A mid-level trough will be located over
the northeast conus. Some energy moving southward through the
trough later this weekend may be strong enough to cause the
development of a weak mid-level low center over the northern
mid-atlantic or southern new england, however surface high
pressure located over quebec southward to the northeast conus
will keep the atmosphere dry enough so that this system will not
be able to produce many if any showers. At this point the best
chance for a brief shower would appear to be Sunday afternoon
over higher terrain in the catskills. High temperatures through
the weekend will be mainly in the 70s with lows in the 40s
across the north country and normally colder outlying areas,
with lower to mid 50s elsewhere.

Long term Monday through Friday
The period starts out on Monday with surface high pressure
anchored along the maine coast, providing continued dry
conditions and slightly below normal temperatures. The high is
expected to remain in place through much of Tuesday, while a
potential tropical system passes by well east of the mid
atlantic region.

Will only mention a slight chance of showers Tuesday night
ahead of a front approaching from the west. A better chance of
at least scattered showers looks to move in Wednesday into
Wednesday night, as the surface boundary moves through and just
ahead of an upper level trough tracking east through the the
great lakes. GEFS indicating pwat anomalies increasing to around
+1 to +2 stdev, although forecast instability looks relatively
weak at this time. So will only mention slight chance thunder
for now. It will become more humid compared to recent days, with
dewpoints rising into the 60s across much of the area.

Some showers could linger into Thursday, especially across the
eastern half of the area, as the upper level trough axis passes
through. GFS indicating a stronger disturbance than the ecmwf,
but there is enough confidence in mentioning 20-30 pops on
Thursday.

Drier weather is expected by Friday, as surface high pressure
tracks east across the ohio valley and mid atlantic region with
ridging extending northward into our region. Temperatures look
to be close to normal for late august, as the flow pattern is
forecast to be zonal late next week.

Aviation 00z Saturday through Wednesday
High pressure at the surface centered over the great lakes
region this evening will shift eastward across eastern canada
through Saturday. While aloft region will be under a weakening
trough. Looking at fair weather with mainlyVFR conditions. Some
patchy fog is expected to develop late at night in favorable
locations, kgfl and kpsf, which will lift and burn off quickly
after sunrise. Linger clouds this evening with mainly clear
skies overnight. Diurnal cumulus will develop on Saturday.

Winds will be light and from the north to northeast.

Outlook...

Saturday night: no operational impact. Patchy fg.

Sunday: no operational impact. No sig wx.

Sunday night: no operational impact. No sig wx.

Monday: no operational impact. No sig wx.

Monday night: no operational impact. No sig wx.

Tuesday: no operational impact. No sig wx.

Tuesday night: low operational impact. Slight chance of shra.

Wednesday: moderate operational impact. Chance of shra... Tsra.

Fire weather
Cooler and less humid conditions are expected for today
into Saturday as high pressure builds into the region. A weak upper
level disturbance could bring a passing shower to portions of the
region Sunday, mainly across higher elevations, otherwise fair
conditions are expected.

Rh values will decrease to minimum values of around 40 to 50
percent this afternoon and again Saturday afternoon, and
increase to around 80 to 100 percent tonight with areas of dew
formation likely.

Winds will be from the north to northwest at 5 to 15 mph today,
decreasing to 5 mph or less tonight. On Saturday, winds will be
from the north to northeast at 5 to 15 mph.

Hydrology
Some light rain showers will be possible this morning across
the mid hudson valley and northwest connecticut. Otherwise, dry
conditions are expected Friday through Saturday night. Isolated
showers are possible Sunday mainly for higher elevations as an
upper level disturbance passes across the region.

and forecast river stages and lake elevations, please visit the
advanced hydrologic prediction service AHPS graphs on our website.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
