Synopsis
A warm and humid air mass will continue to impact the region
into tonight with another upper level disturbance bringing
late afternoon and evening showers and thunderstorms. The heat
and humidity will become oppressive on Monday with still the
threat of afternoon thunderstorms. Cooler and drier weather
will not arrive until Wednesday night into Thursday when a cold
front moves through eastern new york and western new england.

Near term until 6 pm this evening
Updated at 115 pm. Low clouds have finally burned off in the
hudson valley and all of eastern ny and western new england are
getting lots of heating early this afternoon with sunny skies.

Spc meso- analysis is currently indicating MLCAPE values rising
to 500 to 1000 j kg and will likely rise to 1000 to 2000 j kg by
late afternoon. Deep layer shear ranges from 25 to 35 kts which
is sufficient for some organized convection later today. Storms
are developing over northwester pa ahead of a shortwave
approaching the area from the lower great lakes area. Cams are
in good agreement that convection will develop over central ny
through mid-afternoon, then reach eastern ny and western new
england late this afternoon through the middle of this evening.

Cape shear combinations will be large enough for a few severe
storms, and SPC currently has the area in a marginal risk for
severe storms.

Marginal risk for severe thunderstorms across eastern ny and
western new england this afternoon into tonight.

Short term 6 pm this evening through Wednesday
Scattered showers and thunderstorms will be moving across the
area this evening with a few severe storms likely containing
large hail, damaging winds and torrential downpours. After the
storms wind down late this evening, continued ample moisture and
weak low- level flow will lead to lots of low cloud and fog
development especially in the valleys. Temperatures will not
fall much below 70 in many areas with the very moist air mass in
place.

On Monday, another round of storms will be possible. A mid-
level short wave will approach once again from the west, however
the 500 mb heights will actually be rising a bit during the day
so the mid- level short- wave energy will not be as strong as
the past few days. However with the dew points up into the lower
and even mid 70s during the day MLCAPE values will likely be
well over 2000 j kg once again and the mid- level flow will be
moderately strong from the west with deep layer shear 30 to 35
kts. This could set the stage for another severe thunderstorm
risk during the afternoon Monday. With temperatures in the
valleys near 90 and dew points in the lower to mid 70s we have
issued a heat advisory for the hudson valley up to the capital
district during the afternoon for heat advisories up to 95 to
100 degrees.

The main mid-level trough axis will remain west of our area on
Tuesday, setting the stage for the chance for yet another short
wave approaching the area from the west. The atmosphere will
not be quite as moist on Tuesday as today and Monday, but a few
storms will remain possible. Overall, Tuesday appears to be the
least active of the next few days, as another short wave and
associated cold front will approach the area on Wednesday. The
models appear to be in pretty good agreement on a significant
cold frontal passage on Wednesday which could certainly set the
stage for another round of significant thundertorms with severe
potential. This front appears to be strong enough to actually
change the air mass hopefully setting the stage for a more
settled late week period.

Long term Thursday through Sunday
An upper level low pressure system and a surface cold front
will continue to move across the N northeast on Thursday. This
will usher in cooler and a less humid airmass into the
northeast.

Thursday... There will be the threat of some showers early in the day
with wrap around moisture from the uper level low pressure system.

Temperatures on Thursday will be in the 70s from the greater capital
region northward and around 80 across the mid hudson valley.

By Thursday night into Friday... Drying will take place as the upper
level low pressure system moves out of the region and is replaced by
an area of high pressure. As the high pressure builds into the
region, our flow will shift to the north northwest bringing cooler
temperatures to the region. Thursday nights lows will generally be
in the 50s across the region. On Friday... High temperatures will be
in the upper 60s across the adirondacks to the low to mid 70s across
much of the region.

Saturday into Sunday will remain quiet with high pressure.

Temperatures will still remain cool early Saturday and start to inch
closer to normal by Sunday. Saturdays highs will be in the mid to
upper 70s. By Sunday... .High temperatures will be in the upper 70s
to lower 80s.

Aviation 20z Sunday through Friday
As of 130 pm fog and low clouds took some time to erode, but
have finally dissipated. Latest radar showing a complex of
storms over central pa and southeastern ny.

Current models are anticipating line of showers and
thunderstorms moving through the area between 19z-03z. Ceilings
and vsibilities may be reduced to ifr during thunderstorms this
evening. Any storm could produce strong winds, heavy rain and
hail. With the potential of showers and thunderstorms this
evening, there will be the potential for fog and low level
clouds overnight. Will mention ifr ceilings and vsibilities
after 08z with the potential for br fg.

Winds will shift to the southwest around 5-10kts this afternoon
and evening. Winds will be calm to light and variable
overnight.

Outlook...

Monday night: low operational impact. Slight chance of shra... Tsra.

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

Tuesday night: moderate operational impact. Chance of shra... Tsra.

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

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

Thursday: moderate operational impact. Chance of shra.

Fire weather
A warm and humid air mass will continue to impact the region
into tonight with another upper level disturbance bringing late
afternoon and evening showers and thunderstorms. The heat and
humidity will become oppressive on Monday with still the threat
of a shower or thunderstorm. A weak cold front will move through
Tuesday with the best chance of showers or isolated
thunderstorms from the mohawk valley southward.

The rh values will lower to 50 to 65 percent this afternoon and
Monday afternoon. The maximum rh values will be close to 100
percent with fog and dew formation Monday morning.

The winds will be south to southwest around 5 to 10 mph today
into tonight. The winds will be southerly at 5 to 10 mph on
Monday.

Hydrology
Widespread hydrological problems are not expected on the main
stem rivers the next several days.

With thunderstorms in the forecast this evening into Monday
night and also on Wednesday, there is the threat of isolated
flash flooding across the region. The threat for locally heavy
downpours is possible, as humidity levels and dew points remain
high, and with thunderstorms possibly repeatedly moving over the
same area.

Any thunderstorm will be capable of producing flooding of
urban, low lying or poor drainage areas. Some temporary elevated
flows may be briefly possible from thunderstorms on brooks,
streams, creeks and other small bodies of water.

Drier and cooler weather may return by Thursday when a cold
front sweeps through 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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
