.SYNOPSIS...
High pressure builds into the area today and Tuesday, moving
offshore Tuesday night. A cold front approaches Wednesday. The
front moves through Wednesday night, with a frontal wave
developing along it and tracking nearby through Thursday. High
pressure builds in from the Great Lakes Friday into next
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
* Today will be the first day of what will be a 3 day heat wave for
  much of the region.

* Heat Advisories remain in place today.

Some early morning fog has developed across part of the region. Any
fog will remain through about 7-8am, then gradually dissipate
thereafter.

Surface high pressure and Upper level ridging builds into the area
today. 850mb temperatures climb to 19C for parts of the area. This
should result in surface temperatures reaching the middle and upper
90s across the NYC/NJ metro area, with lower to middle 90s across
the remainder of the region. The only exception will be right along
the coast across the far eastern sections of the region, where
temperatures may only stay in the upper 80s. The combination of
these temperatures and dew points once again rising into the middle
to upper 60s and lower 70s, Heat index values should reach the
middle and upper 90s to near 100. Otherwise, it will remain dry
today, with mostly sunny skies.

Dry conditions continue into tonight. Overnight temperatures
wont fall much, with lows in the 70s. The warmest spots will be
across the NYC/NJ metro area with upper 70s expected.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
* Heat advisories remain in effect for Tuesday and Wednesday. Expect
  Heat index values to be in the middle and upper 90s to lower 100s.

Surface high pressure and upper level ridging continues into Tuesday
and Tuesday night. 850mb temperatures rise a couple more degrees, to
around 21-22 C. Expect surface temperatures to be a few degrees
warmer with highs in the mid to upper 90s, potentially hitting 100
across portions of Northeastern New Jersey. A couple of record high
temperatures are possible. See the CLIMATE section for details. The
higher temperatures Tuesday with similar dew points will result in
heat indices of 95 to 104. A few locations may reach 105, however,
with the limited areal coverage a Heat Warning is not expected to be
needed.

It appears that the ridging aloft will now continue into Wednesday
afternoon. As a result, the heat and humidity should stick into
Wednesday. Once again, we are looking at heat indices reaching
the middle and upper 90s to lower 100s. Still feel that
conditions will remain below extreme heat warning criteria.

A cold front approaches late Wednesday. Showers and thunderstorms
are possible Wednesday afternoon into Wednesday evening.

Confidence not high with respect to the severe potential at this
time, however, any storms that do occur will be capable of heavy
downpours.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
Key Points:

*Showers and thunderstorms accompany a cold frontal passage
Wednesday night, and some of the thunderstorms could be strong to
severe and produce locally heavy downpours that lead to flooding,
mainly in urban and poor drainage areas.

*Heat breaks behind the front on Thursday, but conditions remain
unsettled with additional showers and thunderstorms likely as a wave
of low pressure develops along the nearby front.

*High pressure builds towards the area Friday and settles over the
region this weekend, bringing drier, cooler conditions.

&&

.AVIATION /07Z MONDAY THROUGH FRIDAY/...
A weak frontal boundary passes through the area this morning.

Mainly VFR. Exception is some lingering MVFR vsbys at KGON and KBDR,
which should see improvement early this morning as drier air filters
in behind the front.

Light S/SW winds veer around to N/NW into the morning hours.
Northerly flow up to 10 kt this afternoon will be overtaken by
seabreezes at the coastal terminals. Weak flow persists tonight.

 ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Timing of seabreezes (southerly winds) may be off by an hour or two.

.OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY...

Late Tonight-Tuesday: VFR.

Wednesday: Mainly VFR. A chance of showers and thunderstorms late in
the day and at night.

Wed Night thru Thursday: Showers with MVFR possible.

Friday: VFR.

.MARINE...
Conditions will remain below SCA levels through Wednesday. A
cold front moves across the waters Wednesday night through
Thursday. Increased winds behind the front could allow seas to
build toward 5 ft on the ocean late this week, primarily Friday.

&&

.HYDROLOGY...
There are no hydrologic concerns through the day Wednesday.

Locally heavy downpours are possible with a cold front and frontal
wave Wednesday afternoon/evening and Thursday, but confidence
in potential impacts remains low at this point.

&&

.TIDES/COASTAL FLOODING...
There is an overall low rip current risk for ocean beaches
today and Tuesday with only 1 to 2 feet offshore wave heights
and the absence of a wind wave contribution.
