Synopsis
A weak cold front will slowly move through the region during the
evening, and into late tonight. High pressure builds briefly
across Tuesday with a wave of low pressure developing late
Tuesday and approaching Tuesday night. A warm front will move
north of the area Wednesday. A cold then slowly approaches
Wednesday night and moves through Thursday night. High pressure
builds Friday and remains into the beginning of next week.

Near term until 6 am Tuesday morning
A weak cold front will continue to slowly cross the area
tonight. With any lingering showers well offshore and northerly
flow in the wake of the front ushering in drier air, conditions
are expected to remain dry through the rest of the night.

Overnight lows will generally range from the upper 60s to lower
70s, with a few readings in the mid 60s possible across outlying
areas.

Short term 6 am Tuesday morning through Tuesday night
High pressure builds across the area with a northerly surface
flow allowing dew points to be lower and temperatures to be a
few degrees cooler than Monday. Overall, a little less hot and
humid with heat indices reaching a MAX in upper 80s to near 90.

Showers and thunderstorms return Tuesday evening as a wave of
low pressure approaches and moves across the area. High
temperature Tuesday will be in the upper 80s to near 90 with
night time lows in the low to mid 70s.

There is a low risk of rip currents at ocean beaches for
Tuesday.

Long term Wednesday through Monday
A longwave upper trough across eastern canada will be slowly
digging into the upper midwest and northeastern states
Wednesday into Friday, with the eastward progression slowed by a
ridge remaining in the western atlantic. Vort maxes will be
rotating through the upper trough. Meanwhile, at the mid and low
levels, the area remains on the western periphery of the
bermuda high. A slightly cooler and drier airmass will be in
place early Wednesday, then warm advection sets up early and a
warm front is expected to push through the region. There is some
uncertainty as to the timing and areal extent of precipitation
Wednesday and will depend on the energy rotating through the
upper trough. The area will destabilize by the afternoon and
shear and lapse rates will support the possibility of stronger
storms. With the area currently in a marginal risk for Wednesday
have added heavy rainfall and gusty winds in the afternoon and
into the early evening. With the airmass as warm as Monday
decided to lean toward the much warmer GFS guidance and even
raised temperatures for Wednesday highs. Heat indices will
therefore once again peak into the mid 90s.

With the slower progression of the upper low and cold front,
there will be chances of precipitation remaining into Thursday.

The front may even stall for a time Thursday, before pushing
through Thursday night as ridging does build to the west, and
the cooler and drier airmass moves the front through the area.

Canadian high pressure builds for Friday through the beginning
of next week with a much drier airmass.

Aviation 02z Tuesday through Saturday
High pressure builds overnight into Tuesday.

Vfr conditions are expected overnight and Tuesday. An isolated
shower or thunderstorm is possible in the afternoon.

Winds will be light as they veer from SW to N tonight. NE winds
Tuesday morning will shift to the S SE by afternoon.

Outlook for 00z Wednesday through Saturday
Tuesday night-Thursday MainlyVFR, but sub-vfr possible in
showers or thunderstorms.

Thursday night-Saturday Vfr.

Marine
Conditions are expected to remain below SCA criteria for the
waters through Tuesday with sub small craft conditions expected
Tuesday night.

An increasing south to southwest flow Wednesday into Wednesday
night ahead of an approaching cold front will allow for ocean
seas to build to SCA levels by late Wednesday night into
Thursday. The cold front will pass through the waters Thursday
night, with winds shifting to the northwest. Ocean seas will
then subside below SCA levels by Friday morning. Winds across
the forecast waters are expected to remain below SCA levels
Wednesday through Friday.

Then Friday night through Sunday winds and seas will remain
below SCA as high pressure builds into the region.

Hydrology
No hydrologic impacts are expected at this time through the
forecast period.

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