Synopsis
Another quiet weather day for Monday with clear to partly
cloudy skies and seasonable temperatures. An approaching low
pressure system will increases chances for showers and
thunderstorms Tuesday, with showers lingering into Wednesday.

The remainder of the week is shaping up to be mainly dry, with
plentiful sunshine and below normal temperatures.

Near term until 6 pm this evening
As of 744 am edt Monday... Only change for 730 am update this
morning was to increase clouds to start off. Clouds will be
diminishing by this afternoon though and temperatures will peak
in the mid to upper 80s.

Very nice day in store for this Monday to start the work week.

Surface high pressure ridge still reaching the area, centered
over the mid atlantic region will be shifting eastward today.

Light winds will become southerly today. Warm air advection
ahead of next approaching low pressure system, therefore max
temps will edge into the upper 80s. Should be a good day to view
the partial solar eclipse with proper safety precautions, 240
pm will be peak viewing time and skies should mainly be clear at
that time.

Short term 6 pm this evening through Wednesday
As of 500 am edt Monday... More active weather is expected
beginning Tuesday afternoon. Strong southwesterly flow will
continue tonight. Low pressure system takes shape tonight over
the great lakes region as a deepening 500 mb trough moves into
the western great lakes. Pwats will increase during this time
period with low level moisture advecting into the area on the
strong southwesterly flow, nearing 2" by Tuesday morning.

Increasing shear profile expected with 500 mb jet nearing 50
kts. Surface low will pass north of our forecast area on Tuesday
along with trailing cold front which will be reaching our
northern new york zones around 18z. Front moves east across our
forecast area and will be east of vermont by 12z Wednesday
morning. Showers and thunderstorms will develop out ahead of the
frontal boundary, starting in the saint lawrence valley and then
spreading eastward. Models are indicating CAPE in the 1-2k
range, so will have some decent low level instability as well.

Storms will be strongest in northern new york due to placement
of jet lining up with saint lawrence valley, good low level
0-6 km shear. Temperatures will warm to almost 90 across the
area. Heavy rainfall and strong gusty winds are possible with
these storms, but storm motions should be fast enough to avoid
flash flooding. Hi res models depict a line of storms forming
and moving across our area between 20z and 04z. Storms should be
ending by about midnight. Upper level trough will pass north of
the region on Wednesday bringing some shortwave energy across
our area and will have to mention chance for some more showers
with this feature, though mainly confined to the higher
elevations. Cooler air will begin to move into the area later
Wednesday as well behind departing cold front, highs will be
closer to seasonal normals wed.

Long term Wednesday night through Sunday
As of 415 am edt Monday... The north country will remain under
the influence of mid-level cyclonic flow throughout the period,
while high pressure will build at the surface. The period will
start with a surface front that will move across the region with
a chance for showers on Thursday. Behind this front, northwest
to northerly flow will settle in with the main 500mb trough
lagging behind on Friday and result in slight chance of showers.

On Saturday, surface high pressure will build in with drier air
as pwats fall to 0.5-0.7 inches. Outside of a slight chance for
orographic shower or two on Saturday, expect dry conditions
through the end of the period with strong surface ridge
continuing to affect the region into Monday. Temperatures will
be slightly lower than late august normals throughout the
period.

Aviation 12z Monday through Friday
Through 12z Tuesday... Residual fog at kslk will erode this
morning, leavingVFR conditions at all terminals throughout the
day into this evening. S-sw winds will increase to 5-10kts, with
gusts around 20kts developing at kmss and kslk. Winds will
subside this evening, decreasing to around 5 kts or less. Expect
some fog development at kmpv and kslk after 06z Tuesday. Low
level jet will be weaker over these terminals, but still around
20kts. This could lead to another night of intermittent MVFR ifr
fog.

Outlook...

Tuesday:VFR. Likely shra... Slight chance tsra.

Tuesday night:VFR. Likely shra... Occasional tsra.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
