Synopsis
High pressure builds across the area tonight and then offshore
early Saturday. A warm front will then move through the area
toward daybreak Sunday, followed by a cold frontal passage at
night. High pressure briefly follows on Monday. Another
warm front then moves through the area on Tuesday, with a cold
front following for Thursday into Thursday night.

Near term until 6 am Saturday morning
High pressure builds in aloft and at the surface tonight. Nw
winds will quickly diminish this evening, becoming light and
variable overnight. Dry conditions and light winds will allow
outlying areas to fall into the upper 40s, with the mid to upper
50s in and around the nyc metro.

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 20z Friday through Wednesday
High pressure builds over the region this evening, then offshore
tomorrow.

Vfr. NW winds mostly around 20 kt with gusts near 30 kt, weakening
late this afternoon into this evening and gusts ending by midnight.

Winds become light and variable tonight, then southerly on Saturday
as the high moves offshore.

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.
