Synopsis
Weakening low pressure near the DELMARVA this morning tracks
very slowly northeast today, passing southeast of long island
tonight. The low dissipates along the new england coast on
Thursday. A weakening cold front will approach from the northwest
Thursday and Thursday night, then also dissipates over the area
on Friday. Another cold front pushes south of the area Saturday
night. This front then moves back toward the area as a warm
front Sunday night into Monday with the associated cold front
moving through Monday night into Tuesday morning.

Near term /until 6 pm this evening/
As of 730 am, current radar shows a line of convective showers
over the twin forks of long island and into southern
connecticut. This band will head north over the next few hours.

Therefore, have added a slight chance of moderate rain for these
areas through 10 am. Otherwise, forecast is on track.

A low-level easterly jet ahead of weakening low pressure over
the DELMARVA this morning will pass east before daybreak
putting an end to the steadiest rain across eastern ct and long
island.

A closed upper low near the DELMARVA this morning will lift
slowly NE today, in tandem with the surface low. This will keep
the area under a weak NE flow.

Weak lift and saturated low levels will result in light rain
and/or drizzle for much of the day, especially this morning
across ct and li. In addition, with the diminishing NE flow and
saturated low-levels, there will be some patchy fog.

Highs today will be near normal in the lower 60s.

Short term /6 pm this evening through 6 pm Thursday/
Weakening low pressure passes to the south and east of long
island tonight and dissipates along the new england coast on
Thursday.

Low-levels will remain moist with light NE winds. Widespread fog
and drizzle is forecast tonight. The fog may even become dense
overnight before gradually lifting on Thursday.

With a subsidence inversion on Thursday and the development of
a weak return SE flow, low clouds are likely to persist through
the day.

Overnight lows tonight will be mild in the lower to mid 50s,
with highs a bit warmer on Thursday, in the 60s to around 70.

The warmest readings will be across the interior Thursday.

Long term /Thursday night through Tuesday/
A surface cold front will approach the area Thursday night and
weaken as it does so. Although there does seem to be some lift and
instability in association with the front, it is not impressive and
only a slight chance of showers and a passing thunderstorm is
possible.

Bermuda type high pressure will set up over the north central
atlantic. This will bring in some warmth and humidity to the area.

Temperatures away from the coast will reach the upper 70s to lower
80s, while temperatures near the coast will remain in the lower to
middle 70s, with perhaps some upper 60s along the immediate coast.

Dew points will rise into the upper 50s to perhaps some lower 60s.

The next cold front approaches from the northwest Saturday and
pushes south of the area late in the day. This front looks to be a
bit stronger than the previous one, with some lift noted in the
middle and upper levels, but again, nothing too impressive. Most
unstable CAPE values however are in the 1000-2500 j/kg range, mainly
away from the coast, where conditions will be warmest. Lifted index
values of -3 to -5 noted in the 00z gfs. So, showers and a passing
thunderstorm is once again possible Saturday. If further model runs
continue with these values, some strong to severe storms are
possible, but its too early right now.

High pressure builds in for Saturday night and Sunday, with the cold
front settling to our south. The front will then move back north as
a warm front Sunday night into Monday, with a return to unsettled
conditions starting Sunday. The warm front lifts north on Monday,
with the cold front quickly approaching and moving through Monday
night into Tuesday.

Aviation /08z Wednesday through Sunday/
Low pressure tracks slowly toward the area from the south today.

Generally expect ifr ceilings today. Cannot rule out lifr/vlifr
ceilings this morning. Visibilities should remain MVFR to ifr
this morning. During the afternoon, visibilities likely improve
to MVFR or evenVFR for a short time before falling again by
sunset.

Ifr, lifr or even vlifr ceilings and visibilities are forecast
for this evening.

Any moderate to heavy rain departs early this morning, with on and
off light rain and drizzle continuing thereafter.

Northeast winds begin to lighten this morning, and speeds of 10
kt or less are expected through much of the day today. Winds
will be light and variable by evening.

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.
