A cold front will continue to move across the region overnight
will a warm and humid air mass in place ahead of it. Batches of
showers will occur with chances for thunderstorms. Some storms
could produce locally heavy rainfall. With the passage of the
front drier air will filter in on Saturday with increasing
sunshine. Seasonable temperatures return on Sunday, with
perhaps a few passing showers or a thunderstorm over mainly
along and north of interstate 90.

Near term until 6 am this morning
Cold front will continue to move across the region overnight.

Winds have shifted to southwest-west across western adirondacks
and western mohawk valley with southerly flow ahead of the
boundary. A very humid moist airmass is in place ahead of the
boundary with dew points in the upper 60s to lower 70s. Batches
of showers will move across the area with chances for thunderstorms
through the overnight as the front presses through. With high
precipitable water values, 1.91 inches on the 00z aly sounding,
heavy downpours are possible with any storms.

It will be muggy with lows ranging from the lower mid 60s across
the western adirondacks to the lower 70s in the hudson valley
from the poughkeepsie area northward into the capital district
and across northwestern ct.

Short term 6 am this morning through Monday night
Saturday, the aforementioned strong shortwave will be crossing
through the region during the morning hours. Rain and or showers
will likely persist well into the mid morning hours from the
albany saratoga lake george region and points south and east.

Some locally heavy rain will be possible, especially from the
mid hudson valley northeast into NW ct and possibly the southern
berkshires. The rain should finally moves S E of the region by
early afternoon, with clearing expected. However, another upper
level impulse could trigger isolated showers to develop later in
the afternoon, especially across the eastern catskills. It will
become quite breezy by Saturday afternoon, with wind gusts
possibly reaching 25-30 mph. Afternoon highs should reach the
mid 70s to around 80, except 60s to lower 70s across some higher
elevations of the southern adirondacks and southern vt, with
some lower mid 80s possible across portions of the mid hudson
valley where afternoon sunshine and a downsloping flow may
enhance warming.

Saturday night, generally clear to partly cloudy and cooler,
with lows in the 50s to lower 60s.

Sunday, a strong upper level disturbance is expected to approach
in the afternoon. It appears that the best forcing and
associated shallow instability will be mainly across northern
areas, north of i-90. Expect scattered showers and isolated
thunderstorms to develop by afternoon in these areas. With
strong winds anomalously cold air aloft, some gusty winds and
small hail could occur in any deeper convective elements. Highs
should mainly reach 75-80 in valley areas, with 60s to lower 70s
across higher terrain.

Sunday night, any evening isolated scattered convection should
decrease in the evening hours, although could persist across the
southern adirondacks well into the night which will be in
closer proximity to the main upper level forcing. Otherwise, it
should be cool, with lows mainly in the 50s.

Monday-Monday night, another fast moving disturbance may trigger
isolated to scattered showers storms Monday afternoon evening.

Again, with fairly strong winds and cold air aloft, some small
hail gusty winds could occur with any deeper convective
elements, despite fairly isolated scattered coverage. Highs
should reach the 60s and 70s, with lows mainly in the 50s,
except for some 40s across portions of the southern
adirondacks southern vt.

Long term Tuesday through Friday
The extended period begins with a shortwave trough from the corn
belt states digging eastward into the northeast. For the morning
hours, included slight chance pops for the lower half of the CWA and
chance pops for the upper half due to southwest flow aloft and pva.

Increased pops for the afternoon as guidance is in agreement that
the trough axis passes through during this time. While daytime highs
will be about 5 - 10 degrees below normal only in the upper 60s low
70s, included thunderstorm potential due to cool pool aloft, daytime
heating that could lead to some instability (200 - 800 j kg modeled
cape) and impressive upper level dynamics (100-110knots 300mb jet
over new england).

The trough should exit from west to east Tuesday night with cool
canadian air filtering into the region behind it. In fact, as skies
clear overnight and winds stay light, radiational cooling should
allow overnight lows Tuesday night to tumble into the low 50s for
the majority of the CWA and even into the 40s in the adirondacks
(again about 5 - 10 degrees below normal).

Ridging tries to build in from the southwest on Wednesday as high
pressure noses in from the tennessee valley but the high's center
should stay well to our south as strong westerly winds within zonal
flow aloft quickly return over the northeast. Either way, we should
stay mainly dry on Wednesday with highs warming back into the mid
upper 70s. The next system looks to be in the great lakes southern
canadian Thursday Friday with its associated warm front
potentially reaching our region. Given this is nearly a week
away, it's no surprise models differ on timing but the euro and
gfs both suggest the warm front could stall somewhere in our
northern cwa, presenting us with multiple forecast challenges.

Thus did not differ much from the super blend for this period.

Aviation 06z Saturday through Wednesday
Showers have remained scattered within a very moist, weakly
forced environment. Coverage of showers should increase somewhat
through 10-11z as a cold front slowly approaches. Coverage
should be greatest over kpou kpsf as the northern extent of a
broad precip shield associated with the remnants of TC cindy
brushes those terminals. Confidence not high in ifr conditions,
but also not high enough to remove them from the going forecast.

Have targeted the 08-12z timeframe for the most likely period of
ifr with both vsby and cigs. Activity should remain more
scattered at kgfl kalb, whereVFR should prevail outside of
showers. Included a tempo through 10z for MVFR conditions in
showers, though cannot rule out brief period of ifr vsby as
showers could contain heavy downpours. Will amend if necessary.

Weak instability persists, but given dearth of lightning
upstream, have removed TS from the tafs. Cannot rule out a rogue
lightning strike, though.

Drier air filters in rather quickly after 12z with conditions
becomingVFR by mid to late morning at the latest. Few-sctVFR
cu and perhaps some cirrus is all that's expected in the skies
for much of the daylight hours.

Winds will shift from south-southwest to westerly by 12-15z.

Speeds will be mainly around 5-10 kt through mid-morning before
becoming more gusty during the late morning into the afternoon.

Wind gusts of 20-25 kt are possible during the afternoon hours.

Sunday: moderate operational impact. Scattered shra... Tsra.

Sunday night: low operational impact. Isolated shra.

Monday: moderate operational impact. Scattered shra... Tsra.

Monday night: low operational impact. Isolated shra.

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

Tuesday night: no operational impact. No sig wx.

Wednesday: no operational impact. No sig wx.

Fire weather
Wind gusts of 25-30 mph possible Saturday afternoon...

warm and humid weather will continue into tonight, along with
periodic showers and thunderstorms, some of which could produce
locally heavy rainfall. Saturday will see a drying trend behind
a cold frontal passage. Seasonable temperatures return on
Sunday, with perhaps a few passing showers or a thunderstorm
over mainly northern portions of the forecast area.

Rh values are expected to rise to 90-100 percent tonight, then
fall to 40-50 percent Saturday afternoon.

South to southwest winds this evening of 5-15 mph should shift
into the west toward daybreak at similar speeds. On Saturday,
winds will become west to northwest at 10-20 mph with some gusts
of 25-30 mph possible.

Winds will be stronger, and variable in direction in and near
any thunderstorms.

Showers and thunderstorms will become more widespread later
tonight as a frontal system gradually moves across the area. It
will become more humid, so there is the potential for locally
heavy rainfall. Some urban poor drainage flooding and isolated
flash flooding will be possible. Basin average rainfall
forecast to be around a half to three quarters of an inch, but
locally higher amounts will occur in thunderstorms. Showers and
thunderstorms with locally heavy downpours may linger into
Saturday morning from the capital region and points south and

Mainly dry weather then expected for Saturday afternoon with
isolated to scattered showers and thunderstorms possible Sunday
into Monday.

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.
