Synopsis
Waves of low pressure ride along a frontal boundary stalled near
the area through the day and into tonight. High pressure builds
from the west on Wednesday, allowing the boundary to move east
of the area. High pressure remains over the area into the
weekend.

Near term until 6 pm this evening
The heaviest showers this morning have produced three quarters
to around an inch of rain in an hour, leading to additional
flash flooding. This last batch of steady rain will continue to
work through the area over the next several hours before
precipitation becomes more scattered by afternoon. Only minor
changes were made with this update, and the forecast appears to
be on track.

With precipitable water values remaining around 2 inches
through this morning, the flash flood watch was extended through
noon today. The watch was also extended eastward to include the
remainder of the forecast area as many locations have already
received 1-2 inches of rain with an additional half to one inch
of rain expected. At this point the best instability remains
offshore, so the majority of the precipitation should fall as
heavy showers, with only isolated thunder possible.

The bulk of the precipitation will come to an end late this
morning as the wave exits the area, but the chance of showers
will linger across the area through this afternoon with the
front just offshore and an upper level trough over the region.

Under plenty of cloud cover, temperatures will be below normal,
with highs only rising into the mid 70s.

There is a moderate risk of rip currents for the atlantic ocean
beaches today, possibly becoming high this afternoon across
eastern suffolk county.

Short term 6 pm this evening through 6 pm Wednesday
The final wave along the front passes offshore overnight, but
with the front continuing to gradually shift south, the best
chances for precipitation will be across long island and far
southeastern connecticut. Depending on how close to the coast
the final wave passes, patchy fog development is possible in
areas where winds become light.

Dry conditions return Wednesday morning as the front shifts
farther offshore and high pressure builds in from the west.

Under increasingly sunny skies, temperatures are expected to
rise into the lower 80s.

There is a low risk of rip currents at the atlantic ocean
beaches on Wednesday

Long term Wednesday night through Monday
Strong polar upper low drops into hudson bay during the mid to late
week, gradually shearing the closed low currently over northern
quebec towards greenland. The associated deep eastern us troughing
will slowly weaken through the week as a result, with weak upper
ridging signaled for the weekend ahead of the next closed
shearing eastward just north of the great lakes.

At the surface, generally tranquil conditions expected, with weak
and elongated high pressure sprawled across the eastern us in wake
of the offshore cold front slowly drifting eastward. A gradual
moderation in temps expected through the period, starting a
seasonable levels with comfortable humidity mid week and rising to
above seasonal with increasing humidity late week into the
weekend.

Aviation 11z Tuesday through Saturday
Waves of low pressure will ride along a stalled frontal boundary
near the area.

The last batch of steady rain will continue to work through the
area over the next several hours before rain becomes more
scattered this afternoon.

Generally widespread MVFR through the morning, with ifr
conditions in any heavier shower.VFR conditions are expected to
return in the middle to late part of the day.

Winds remain fairly tricky initially with multiple boundaries
moving across the area. Winds should generally be from the
north northeast less than 10kt before turning toward a more
northwesterly direction following the cold front passage.

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.
