Synopsis
A cold front will slowly move and weaken as it moves across the
area this evening. 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
Heat advisory remains in effect through 8 pm for much of the
region with heat indices expected to reach 95 to 100 degrees in
these areas. The exception is eastern suffolk county on long
island where heat indices will generally be in the lower 90s.

Thunderstorms will continue to develop across the area through
late this evening as a cold front moves slowly east across the
region through early this evening. The front is expected to
weaken as it crosses long island, eventually moving south of
long island overnight. Some of these thunderstorms are capable
of producing gusty winds and heavy rain.

Storms should diminish late tonight with the loss of synoptic
forcing and instability. High pressure builds across the area
from the north late tonight and into Tuesday.

Temperatures tonight will be in the upper 60s to lower 70s.

There is a moderate risk of rip currents at ocean beaches
today.

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 today. 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 20z Monday through Saturday
A cold front approaches today and moves through tonight.

MainlyVFR this afternoon. Sct showers and thunderstorms
are expected with the most likely timing between 20-24z for the
nyc terminals. Will cover this threat with tempo groups. Any
thunderstorms may lower flight categories to MVFR or even ifr
for brief period.

Winds mostly SW to S under 12 kt. Gusts in near tstms
potentially exceed 35 kt.
