Synopsis
Widespread thunderstorms will occur ahead of a cold front this
afternoon and evening. Some storms are expected to become severe
with damaging winds, torrential rainfall, and dangerous cloud-
to- ground lightning. The threat for showers and thunderstorms
will end tonight with the passage of the cold front. Much cooler
and drier air will move into the region tomorrow, with dry and
comfortable conditions expected for the rest of the week.

Near term until 6 am Wednesday morning
Tornado watch 461 remains in effect until 9pm for the
adirondacks, mohawk valley, and warren county...

severe thunderstorm watch 463 is in effect for much of
eastern new york and all of western new england...

as of 715 pm edt, line of strong to severe storms with a few
discrete cells ahead of it continues its eastward trek across
the forecast area this evening. Strongest storms have exited the
adirondacks but are now entering the greater capital district
and catskill region, with damaging winds being the main threat.

Over the past few hours, there have been reports of trees and
power lines down along with a funnel cloud in southern herkimer
county. There is also a secondary line associated with the cold
front just now entering western new york. Both lines of convection
will continue across the forecast area through the remainder of
the evening.

In terms of the forecast, updated pops based on radar trends as
well as freshened up the hourly temps. Temperatures across the
adirondacks dropped into the 60s from the earlier convection.

Prev disc...

impressive convective line continues its march
eastward this afternoon and it now just entering the adirondack
region. There are strong winds associated with this line, as
well as good potential for brief spin-ups and rotation along the
line. Spc's tornado watch 461 remains in effect until 9pm for
the adirondacks, mohawk valley and warren county. The remainder
of our area has just been put under a severe thunderstorm watch
and is in effect through midnight tonight. Latest hi-res cams
have a good handle on the current convection and march the
initial line through our area by midnight tonight. A secondary
line, associated with the surface cold front, is expected to
follow behind the initial line but shouldn't have much
instability to work with. Speaking of instability, the special
18z sounding we launched shows over 3k surface-based cape, 45
knots of 0-6km shear, mid-level lapse rates around 6 deg km and
pwat of 1.7 inches. Temperatures currently are in the upper 80s
with dewpoints in the lower 70s... A very juicy atmosphere for
severe weather. Storms are capable of producing heavy rainfall
as well which could result in localized flooding, especially for
urban and poor drainage areas. Although the fast flow aloft
should keep cells moving, the expected multiple rounds of
convection could result in some training, which may allow for
excessive rainfall in some areas. Wpc has much of the area in a
slight risk for excessive rainfall today, so flash flooding
cannot be ruled out today.

Any remaining showers and convection should begin to wane after
midnight tonight with the passage of the cold front but
temperatures will remain fairly mild, in the upper 50s
(adirondacks) to the upper 60s (mid- hudson valley).

Short term 6 am Wednesday morning through Wednesday night
Behind the front, cooler and less humid air will work into the
region. Mainly dry weather is expected through Wednesday,
although cannot totally rule out a lingering rain shower across
the adirondacks or mohawk valley for later Wednesday into
Wednesday night, as the passing upper level trough picks up
some moisture off lake ontario and allows for a lake-enhanced
shower or two. Highs on Wednesday will reach the mid 70s to low
80s. Overnight lows will mainly be in the 50s, with some 40s
across the higher elevations. Sky cover will generally be partly
cloudy.

Long term Thursday through Tuesday
Extended period of fair weather with slightly below normal
temperatures.

Canadian high pressure at the surface will build in and shift
southward as it expands across the great lakes region and the
northeast over the weekend into early next week. An upper level
trough will remain over region.

Short waves are expected to rotate through the trough on Thursday
and Friday. Some afternoon showers possible each day from sun's
heating and cold air troughiness aloft, mainly over higher terrain.

Looking at temperatures around 5 degrees below normal with highs
generally in the mid 60s to upper 70s and lows in mid 40s to mid
50s. Cooler readings are expected across the higher terrain of the
western adirondacks, eastern catskills and southern green mountains
of vermont.

In addition to the cooler temperatures, we will have low humidity
levels with dew points in the 40s and lower mid 50s.

Aviation 00z Wednesday through Sunday
Line of showers and some strong thunderstorms currently extends from
the lake george area to kgfl southwest to the catskills. We expect
this line to continue to move southeast this evening and bring
thunderstorms to all the TAF sites between 23 00z and 23 05z.

Some fog may develop after midnight with the moist ground and
rain cooled atmosphere. At this time, expecting only MVFR fog
as winds and drying behind the cold front should be strong
enough to keep dense fog from forming.

Frontal passage is expected between 06z and 12z Wednesday with
the winds shifting from southwest to the northwest behind the
front. Winds Wednesday will be mainly from the northwest at 5 to
15 kts.

Outlook...

Wednesday-Saturday: no operational impact. No sig wx.

Fire weather
Most areas should see a wetting rainfall this afternoon and
evening due to the passage of a pre-frontal trough and surface
cold frontal boundary. Southerly winds will be 15 to 20 mph
today with gusts up to 30 mph, and will switch to the west by
tonight at 5 to 15 mph.

Behind the front, cooler and less humid conditions will be in
place for the rest of the week. Rh values look to fall to 45 to
55 percent on Wednesday afternoon with westerly winds of 10 to
20 mph.

Hydrology
A line of strong to severe thunderstorms will cross through the
area this afternoon and evening. Any thunderstorm will be
capable of producing locally heavy downpours and could lead to
isolated flash flooding. The locally heavy rainfall may also
result in minor flooding of urban, poor drainage and low lying
areas. Behind this frontal system, mainly dry weather is
expected for the rest of the week.

Basin average rainfall on Tuesday will generally be around a
half of an inch to an inch, although point totals may be
higher. This rainfall will only allow for minor rises on rivers
and streams. River and stream levels should quickly recede by
Wednesday and then remain steady for the rest of the week.

For details on specific area rivers and lakes, including
observed and forecast river stages and lake elevations, please
visit the advanced hydrologic prediction service AHPS graphs
on our website.

Equipment
The kenx radar will likely be down through at least Friday,
september 1st for the bull gear replacement. We are waiting for
a roc maintenance team and parts to arrive to assist local
technicians with the repairs.

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.
