Synopsis
Dry conditions and seasonable temperatures can be expected
through Tuesday with high pressure remaining in control. A cold
front approaching from the west will bring the chance for
showers Tuesday night. Showers and perhaps a few thunderstorms
may accompany the front as it moves through the region
Wednesday. High pressure builds in from the ohio and tennessee
valleys Thursday before the next cold front approaches from the
great lakes toward the end of the week.

Near term through Monday night
High pressure centered over southeastern canada will continue to
ridge down the eastern seaboard and keep us dry through the
period. Meanwhile, an upper low that was located nearby to our
east (nj-southern new england) is expected to deepen as it moves
offshore this evening and then gradually up through the new
england coastal waters on Monday.

Forecast soundings show the column drying over the next 24
hours in response to large-scale subsidence in wake of the
departing low (and is eventually reinforced by an upstream
ridge that builds into the region later Monday). The end result
will be clear skies tonight and a lot of sunshine tomorrow.

Ideal radiational cooling conditions tonight will favor yet
another episode of river valley fog early Monday morning.

Additionally, temperatures should drop rather precipitously
after sunset. With an even drier airmass in place for tonight,
early Monday morning may be slightly chillier than this morning
with low temperatures ranging from the lower 40s in the western
catskills to the lower 50s in the urban valleys (can't rule out
the most sheltered locales in otsego and delaware counties
dropping below 40 f). Full heating will allow temperatures to
rebound quickly with afternoon highs generally in the mid 70s
(close to climo for late august).

The upper-ridge axis progresses downstream of the area Monday
night. Mid and high clouds are expected to overspread the area
from the southwest overnight as an upstream shortwave trough
approaches. However, the surface high should still have enough
of an influence to keep the deeper lift and moisture shunted
upstream of the area. The forecast for Monday night is dry
accordingly. Temperatures are not expected to drop quite as much
as in recent nights owing to the increasing cloud cover and a
tightening pressure gradient that should keep a light wind going
into night at most locations.

Short term Tuesday through Tuesday night
Low pressure moving through lower canada and the great lakes
will spread showers and thunderstorms into our region Tuesday
and Tuesday night. Modest instability and shear suggest the
threat for severe weather will be minimal.

Despite steep southerly flow, thickening clouds will suppress
temperatures and keep readings in the lower or middle-70s.

Long term Wednesday through Sunday
Low pressure will continue to spin over lower canada during the
middle of the week before finally pulling north on Friday. This
system will drag a cold front across ny and pa late in the week
and keep a daily threat for showers or an isolated thunderstorm
over our region.

Temperatures will slowly warm from the middle-70s on Wednesday
to near 80 on Friday.

A long wave trough will dip into the ohio valley next weekend. A
relatively dry westerly flow will ensue, but the presence of the
trough will cause a slight chance for a shower.

Aviation 19z Sunday through Friday
Rest of this afternoon... Sct-bkn CU field generally has been
4-7 kft agl so far this afternoon. Outside of far SE new
england, the one site reporting MVFR conditions (at the time the
18z TAF were sent out) across the northeast, great lakes,
midwest, and northern mid-atlantic region was bgm with a bkn 3
kft deck. This restriction should be temporary as mixing deepens
and cloud bases rise slightly. Winds varying between e-se and
ne will be 5-10 kt through the remainder of the afternoon.

Tonight... VFR this evening. Winds become light and variable
after sunset. River valley fog expected to develop late tonight
into early Monday morning. The fog will likely be a bit
shallower than last night (owing to a stronger nocturnal
inversion and closer to the ground) but kelm will once again be
the most likely TAF site to be impacted. Opted for a four-hour
tempo group (09-13z) with lifr restrictions.

Monday... VFR everywhere after the fog lifts mid morning. E
winds 4-8 kt during the day.

Outlook...

Monday night... VFR as increasing cloud cover will make the
setup for river valley fog less favorable than in recent nights.

Tuesday... VFR.

Tuesday night through Wednesday night... Restrictions possible
in showers and storms.

Thursday and Friday... Restrictions possible during the early
morning hours mainly at elm due to river valley fog. OtherwiseVFR.

Bgm watches warnings advisories
Pa... None.

Ny... None.

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.
