Synopsis
High pressure will build in tonight, and then pass offshore
early Saturday. A warm front will then move through toward
daybreak Sunday, followed by a cold frontal passage Sunday
night. High pressure will briefly follow on Monday. Another warm
front will then move through on Tuesday, with a cold front
following for Thursday into Thursday night.

Near term until 6 am Saturday morning
Cloud cover across southern ct and long island may take longer
to dissipate than originally forecast, otherwise as high
pressure builds in aloft and at the surface, NW winds should
quickly diminish this evening, becoming light se-s along the
coast as a shallow weak back door front that has passed thru the
eastern coastal waters progresses westward overnight as shown by
h8-10 thicknesses falling from the east as the high builds just
north.

The conditions and light winds will allow temps to fall to the
upper 40s in some outlying areas, and to the mid to upper 50s
in around nyc.

Short term 6 am Saturday morning through Saturday night
Upper ridge axis pushes offshore in tandem with the low-level
ridge on Saturday. A return southerly flow will gradually
strengthen with some gusts up to 20 mph in the mid to late
afternoon hours.

Highs Saturday will top out around 70 at the coast and in the
low to mid 70s elsewhere.

Clouds will be on the increase in the afternoon as warm
advection ensues on the back side of the ridge. Mid and high
level clouds will filter in by early evening with a chance of
showers and isolated thunderstorms. The best chance looks to be
after midnight and across ct and eastern li, where the best
thermal forcing and moisture advection will take place. Rainfall
amounts should be light and generally less than a quarter inch.

Lows will be in the upper upper 50s.

There is a low risk for the development of rip currents
Saturday.

Long term Sunday through Friday
Any warm advection precipitation in the morning on Sunday will
quickly move east giving way to mostly sunny skies and above normal
temperatures as offshore, westerly flow develops. By evening, the
next short wave passes to the north, with the attendant cold front
moving through. Although coverage may be isolated, model soundings
indicate nearly unidirectional west-northwest flow that strengthens
with height, about 50-60 kt deep layer shear and mid-level lapse
rates of around 6.5 c km that will support stronger updrafts and
potentially hail. Additionally, a dry subcloud layer may enhance any
downdrafts, so expect a few clusters of storms with strong winds to
be possible. The loss of diurnal heating will gradually allow these
storms to weaken overnight.

Brief high pressure for Monday will lead to mostly tranquil weather,
with temperatures briefly closer to climatological normals. The high
moves offshore Tuesday, allowing a return to warm advection with a
front slowly moving northeastward through the region, which may
spark a few thunderstorms.

We then stay solidly in the warm sector for Wednesday and Thursday,
with temperatures well above climatological normals and an
increasing chance for diurnal thunderstorms. Once again although
forcing for ascent is weak and confined to a subtle short wave and
surface trough for Wednesday, steep low and mid level lapse rates
may contribute to a few stronger cells. Chances of strong
thunderstorms then increase into late Thursday with the approach of
a cold front, especially with the increasing wind field as the upper
trough nears. The front then passes through overnight, marking a
return to more seasonable conditions.

Aviation 03z Saturday through Wednesday
High pressure builds over the terminals tonight, then offshore
on Saturday. A warm front approaches from the west Saturday
night.

Vfr. Winds will continue to weaken overnight as they veer to the
n and ne. Some veering to the e-se is possible at city terminals
early Saturday morning with light and variable elsewhere. Winds
then become southerly 10-15 kt, strongest at the coast through
the day.

Showers and isolated thunderstorms are possible Saturday night,
but there is low confidence in coverage and timing.

Outlook for 00z Sunday through Wednesday
Saturday night Chance of MVFR or lower in
showers and isolated thunderstorms overnight.

Sunday MostlyVFR. Chance of MVFR or ifr early in the
morning. Slight chance of showers.

Monday Vfr

Tuesday-Wednesday Chance of MVFR or lower with
showers thunderstorms, mainly in the afternoon and evening each
day.

Marine
Northerly winds quickly fall off this evening as high pressure
builds into the waters, with winds becoming e-se as a weak back
door front progresses westward.

Winds and seas are expected to remain below SCA levels Sunday
through Wednesday, although thunderstorms will be capable of
producing locally hazardous conditions at times.

Hydrology
No hydrologic impacts are anticipated into next week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
