Synopsis
High pressure continues to slowly move offshore overnight as a
warm front approaches from the south and west. A cold front
approaches from the midwest Thursday, then passes through the
area Thursday night. High pressure returns to the region for
Friday and Saturday. A frontal system will pass through the
region late Saturday into Sunday. The front will stall to the
south of the region Monday with a wave of low pressure passing
through Monday night. High pressure returns for Tuesday and
Wednesday.

Near term until 6 am this morning
Based on latest radar trends and development of additional
showers in the warm front forcing, adjusted probabilities
overnight and into Thursday morning. Also, temperatures and dew
points were mainly adjusted upward overnight as warm advection
increases across the region, along with cloud cover.

Additionally, a return to onshore flow is quickly increasing
low level moisture across the area with dew points slowly
increasing along the coastal areas.

Short term 6 am this morning through 6 pm Friday
Early morning showers will become isolated by afternoon as the
warm advection wanes. Any rain in the morning should be on the
light side.

The potential for a round of more significant convection arises
during the late afternoon and early evening hours on Thursday.

An upper low north of the great lakes on Thursday will track
ese, sending height falls into the region. This coupled with
moistening low-levels will destabilize the airmass. Their are
mixed signals from the guidance during this period as to whether
all the ingredients will come together at just the right time
to erode a low-level cap and overcome dry air in a deep-layered
westerly flow aloft. Additionally, the best dynamics will
reside north of the area. Mid level lapse rates do steepen to
around 7-8 deg c km and 0-6 km bulk shear is around 50 kt, which
will support hail in any stronger storms that develop. Href
members show varying solutions with most in the camp of the
convection being scattered in nature. There is also the question
as to whether the shear is sufficient to maintain a cold pool
to push through the maritime airmass. So yes, there could be a
few strong and or severe thunderstorms, but that should mainly
be to the north and west of nyc. The convection will likely
dissipate as it approaches the coast. The best timing looks to
be between 6 and 10 pm, from west to east.

Warm advection during the first half of the day will result in
mostly cloudy skies, but there should be some breaks in the
afternoon. This will also be a factor into how much we can
destabilize.

Gusty s-sw winds ahead of the front will get up to 25 mph,
mainly near the coast.

Highs will be nearly seasonable levels, in the upper 60s at the
coast, to the mid 70s north and west of nyc.

Cold front passes through between 10 pm to 1 am Thursday night
with gusts NW up to 25 mph developing toward daybreak.

Long term Friday night through Wednesday
High pressure builds across the region on Friday and most of the day
on Saturday, so expected dry conditions with temperatures in the mid
to upper 70s on Friday and upper 60s and lower 70s on Saturday. A
cold front will then approach the region Saturday evening and
overnight, bringing a threat of showers and thunderstorms across the
area. The front should push south on Sunday keeping the area under a
slight and chance probabilities of showers Sunday and into memorial
day. Temperatures on Sunday will be in the upper 70s to mid 80s with
temperatures on memorial day in the mid to upper 70s.

Dry conditions return on Tuesday and Wednesday as high pressure
builds into the region. Temperatures on Tuesday will start out in
the low 70s then warm up into the mid to upper 70s on Wednesday.

Aviation 04z Thursday through Monday
High pressure just offshore moves farther out to sea tonight.

Vfr tonight with winds at 10kt or less.

For Thursday, a few showers possible within a few hours either
side of daybreak, but mostlyVFR. Tstms and sub-vfr conds
possible late aftn early evening.

Outlook for 00z Friday through Monday
Thursday night MostlyVFR. Chc MVFR ifr with shra TSTM in the
evening.

Friday-Friday night Vfr. NW gusts 20-25kt during the day.

Saturday MostlyVFR, except chance of MVFR or lower
in showers thunderstorms late day and evening.

Sunday MostlyVFR. Slight chance shra MVFR.

Monday A chance of shra and MVFR.

Marine
Winds and seas remain below SCA levels through Thursday.

A southerly flow ahead of a cold front Thursday night may allow
for ocean seas to build to marginal SCA levels, with seas then
falling below 5 feet Friday as a northern flow develops behind
the cold front. Winds and gusts are expected to be near or just
below SCA levels Thursday night as mixing will be limited with
a low level inversion in place.

Gusts on Friday may approach 25 to 30 kt briefly in a gusty
northerly flow. Friday night into Saturday night winds and seas
will remain below SCA levels as high pressure moves across the
are waters Friday, and a weak frontal system passes through
Saturday into Sunday.

Hydrology
There is the chance for scattered showers and thunderstorms
during late Thursday afternoon and evening. Significant
hydrologic impacts are not expected at this time, although there
may be some minor urban flooding in association with any
heavier rain associated with any thunderstorms.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

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.
