.KEY MESSAGES...
1) Heat advisory remains in effect for much of the region
Thursday through Friday with hot and humid conditions expected.

2) There is a risk for isolated to scattered severe thunderstorms
and localized flash flooding during the late afternoon and evening
hours Thursday and Friday.

3) Still hot but not as humid for the weekend, temperatures cool off
more early next week. Multiple chances of showers and possible
thunderstorms.

.DISCUSSION...
.KEY MESSAGE 1...

An upper ridge will briefly re-establish itself over the region on
Thursday and again on Friday behind any storms that move through on
Thursday evening. This will be ahead of an upper level trough, which
will support a surface low pressure system that will move through
the region on Friday night. In the warm sector of this system, 850
mb temperatures will surge toward the 20 C mark, translating to
surface temperatures in the upper 80s to lower 90s. Meanwhile, there
will be an increase in surface moisture across the region with dew
points in the upper 60s to lower 70s. Together, this will allow for
Heat Index values to be in the mid 90s to lower 100s for Thursday
and Friday with the Heat Advisory remaining in effect for much of
the area. Temperatures and heat index values will remain muted in
the lower to mid 80s for coastal SE CT and Eastern Long Island, and
these areas will remain out of the Heat Advisory.


.KEY MESSAGE 2...

The airmass over the region is expected to become much more unstable
on today with high heat and humidity (dew points around 70).
Confidence is increasing for a complex of showers and thunderstorms
to move in from the NW during the late afternoon and evening hours.
A high CAPE environment with mid level lapse rates around 6.5C will
be sufficient enough to support deep convection. Shear is marginal
but may be just enough to support cold pool maintenance. Isolated
pulse severe is the main threat with some small bowing segments
possible. While temperatures are warm aloft, deep convection will
warrant a large hail threat in addition to damaging wind gusts. SPC
has a slight risk with isolated to scattered coverage. WPC has
included the area in a marginal risk for excessive rainfall, which
is localized flash flood threat. High PW values around 2" along with
deep convection favor high rainfall rates. Max hourly rainfall rate
look to be about 2 inches.

Friday will feature another high CAPE, weak shear day with evening
showers and thunderstorms likely along and ahead of an approaching
cold front. Expect isolated to scattered severe thunderstorms with
the main threat being damaging wind gusts. SPC once again has much
of the area in a slight risk for severs storms, though a more
prominent threat of damaging wind gusts, especially for western
areas. Flash flood threat looks isolated at this time.


.KEY MESSAGE 3...
Still hot for the weekend with quite a few locations reaching highs
in the lower 90s but lower dew points will limit the extent of the
heat index values as the airmass will become less humid. Heat
indices max values stay near 90 or less. Unsettled weather pattern
establishes itself, nearly zonal mid level flow. Periodic low
pressure disturbances with periodic chances of showers heading into
early next week.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
Weak elongated low pressure resides near the region through the TAF
period. A cold front approaches from the west Friday.

Mainly VFR through remainder of TAF period, however MVFR or lower is
possible within any showers and thunderstorms. The window for any of
this activity is generally in the 21-03Z timeframe. There is the
possibility that some thunderstorms could become severe, and would
facilitate TAF amendments. Any showers / thunderstorms would taper /
end very late in the evening or early in the overnight.

The winds increase out of a general SW to WNW direction to near or
just above 10 kts. Some locations will have gusts up to 20 kt late
afternoon into early evening. The winds then go generally westerly
tonight into Friday. Winds speeds tonight will be around 10 kts for
the city terminals, and 5 to 10 kt for most outlying terminals. W to
SW winds take shape again with similiar wind speeds Friday.

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

Confidence remains low in the coverage and timing of showers and
thunderstorms towards this evening, and could be 1-3 hours off from
TAF.


.OUTLOOK FOR 12Z FRIDAY THROUGH MONDAY...

Friday: VFR initially. Then MVFR or lower possible at times with
chances for showers and thunderstorms late afternoon into the night.
Again, potential for some thunderstorms to be severe with main
threat being damaging winds.

Saturday: VFR.

Sunday: VFR early day, then slight chance of a shower or
thunderstorm with brief MVFR or lower possible. Showers likely at
night with MVFR or lower possible and a slight chance of a
thunderstorm. Southerly wind gusts 15-20 kt afternoon and evening.

Monday: Mainly VFR. Slight chance of a shower with MVFR
possible.

.MARINE...
Sub-SCA conditions are expected through much of the forecast
period with near SCA conditions possible once again for the
ocean waters Sunday afternoon through Monday morning.

Rip Currents...

For today, there is a moderate rip current risk with SW winds around
10 kt and surf around 3 ft.

For Friday, the risk is low with with SW-S winds around 10 kt  and
surf heights around 2 ft
