Synopsis
High pressure centered over eastern canada and extending into
new england and the northeast will gradually slide east today. A
stationary front well to the southwest will approach as a warm
front tonight and move north Monday. Another frontal system
affects the region Tuesday and Tuesday night. High pressure
builds to the west Wednesday and Thursday. Another low pressure
system approaches Friday.

Near term /until 6 pm this evening/
Surface high pressure was extending into the region from
southeastern canada with a northeast to east flow, with a cold
air damming situation as a stationary front remains from ohio
across west virginia and through northern virginia. Convergence
and weak thermal forcing has resulted in a band of light rain
from western upstate new york, and across northeastern new
jersey to western long island. Temperatures were above freezing
across the interior and do not expected freezing rain possible
that some higher elevations of western orange county new york
briefly have freezing rain with mesonet stations reporting
temperatures just above freezing.

Otherwise with the surface and upper ridge into much of the area
keeping the eastern CWA dry until late this morning with just
slight chance probabilities and then by late this afternoon, as
the ridge weakens, will have low chance probabilities across
the cwa.

Short term /6 pm this evening through 6 pm Monday/
The closed and nearly cut off low that was over missouri will
continue to open and weaken as the shortwave gets picked up by a
weak southern stream flow, and the wave moves into the eastern
ridge. There remains some timing difference with the movement of
the warm front and low tonight into Monday. Also, with weak
forcing unsure how much precipitation will occur. So have
lowered probabilities into the likely category, with the higher
chance west and north late tonight into Monday.

Long term /Monday night through Saturday/
With the wave continuing to dampen late Monday into Monday night
with weak ridging ahead of the next shortwave, there may be a
break in the precipitation. However, with the uncertainty, and
to keep continuity have continued with slight chance
probabilities Monday night.

Yet another shortwave approaches in the weak southern stream as
this wave also dampens as wave approaches the mid atlantic.

There are timing differences and whether or not the shortwave
will phase with a digging northern stream shortwave Tuesday.

With uncertainties will keep probabilities at low chance Tuesday
into Tuesday night.

Wednesday and Thursday look to be dry with high pressure building
in. Cold air advection appears to be delayed enough to the point
where highs on Wednesday end up above normal, then near-normal for
Thursday. Friday could be completely dry as well, but perhaps some
rainfall sneaks into the western zones by the end of the day. High
temps again near normal. Global models then disagree with the track
of an area of low pressure that could bring rainfall on Saturday.

Have capped pops at 40% for now.

Aviation /08z Sunday through Thursday/
As a cold front settles south across the mid atlantic states
overnight, high pressure will build southward across the area
with a push of drier air.

Much of the area will experience MVFR conditions for a time
overnight withVFR conditions working in from the ne. Amendments
area likely for the timing of the improvement. If conditions
can clear overnight there is low potential for a brief period of
fog from 09-12z.

Flight cat Sunday morning uncertain. Started offVFR, then lowered
to MVFR after about 13z-14z with light rain moving in well in
advance of the warm front. Dry air through may win out, delaying the
onset of the MVFR CIGS and light rain until the afternoon/evening,
especially east of the nyc terminals.

N-ne winds around 10 kt will gradually pick up overnight, then the
direction becomes more easterly after daybreak, with a few gusts g15-
20kt possible in the afternoon at the coastal/nyc metro terminals.

Outlook for 06z Monday through Thursday
Sunday night Lowering to ifr/lifr with light rain/drizzle/fog
ahead of an approaching warm front.

Monday Ifr/lifr to start. Conds could improve to MVFR orVFR by
late morning or afternoon if the warm front moves through.

Monday night-tue night Ifr likely, lifr possible with low
clouds/fog.

Wednesday Vfr. NW winds g20-25kt, possibly stronger.

Thursday Vfr.

Marine
Northeast flow strengthens today between high pressure to the north
and the cold front to the south/low pressure to the west. Marginal
sca gusts are possible on the ocean waters through tonight. The
resultant easterly fetch should allow for ocean seas to build to 4
to 6 ft. Winds are expected to weaken and veer SE on Monday as a
warm front works into the waters... But e/se swells will likely keep
seas at SCA levels through the evening.

Otherwise, sub-sca conditions are expected across all waters briefly
on Tuesday before gradually building through the evening in
strengthening southerly flow ahead of a low pressure approaching
from the west. Strong west-northwesterly flow with gusts to 25 kt
will develop on Wednesday as a cold front passes which will
initially allow seas to stay elevated at SCA levels before gradually
shifting east of the ocean waters. Stronger winds may persist into
Thursday before weakening by late week as high pressure briefly
builds over the area.

Hydrology
One quarter of an inch to one half an inch of rainfall is
possible today through Tuesday night.

No hydrologic issues are anticipated through Tuesday.

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.
