Area Forecast Discussion
National Weather Service New York NY
808 PM EDT Tue Aug 7 2018

.SYNOPSIS...
Weak low pressure and an associated cold front will move slowly
through the northeast tonight through Wednesday night, moving
offshore Thursday. Weak high pressure settles over the region
Friday ahead of the next cold front, which may stall nearby this
weekend into early next week.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Forecast was updated, increasing shower and thunderstorms
chances in the city and surrounding areas this evening as cells
move through a high CAPE environment.

A Heat Advisory remains in effect for the entire area through
800 PM this evening. The heat advisory has been expanded for
tomorrow, see short term section.

The overall pattern at the surface and aloft remain through the
overnight with a shortwave moving into the longwave upper
through and weak low pressure moving into the northeast. The
movement is rather slow as the downstream Atlantic ridge
remains in place. Convection through mainly this evening will
be diurnally driven as only a weak surface trough was across the
region, with the cold front well to the northwest. For late
tonight will keep a slight chance of rain as some very weak
energy does move in aloft. However, thinking is that most of the
region will be dry. The warm and humid airmass remains in
place.

There is a moderate risk for rip current development at
Atlantic Ocean beaches through this evening.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/...
The heat advisory has been expanded into the lower Hudson
Valley, and into Fairfield and New Haven counties of CT, and
into western Suffolk county NY, and western Passaic county,
through 600 PM EDT Wednesday. The heat Advisory remains for
most of northeastern NJ and NYC and Nassau counties through 600
PM Wednesday.

The upper trough moves slowly through the region Wednesday
through Thursday, with the GFS slightly quicker and less
amplified.

The better chance of convection will be Wednesday afternoon and
evening as a cold front and surface wave move into the region.
The cold front will pass through during Thursday. Precipitation
does linger, and if the upper trough is evening slower to move
through, precipitation may remain into Thursday night,
especially across the east. With the slower timing of the
convection and cold front Wednesday now looks to be warm and
humid across much of the region, with heat indices reaching the
mid and upper 90s. The heat advisory was expanded. Did not
include Middlesex and New London counties or the twin forks as
widespread heat indices in the mid 90s are not expected at this
time.

There is a moderate risk for rip current development at
Atlantic Ocean beaches on Wednesday.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Weak high pressure gains control of the weather Thursday night
and Friday. Dry for the most part, but there could be an
afternoon shower or thunderstorm NW of the city. Highs mostly
85-90 combined with dewpoints in the middle and upper 60s will
result in heat indices below 95.

A weak cold front will then be stalled nearby Friday night
through the weekend. This brings a chance of showers and
thunderstorms for the entire period with the higher chances
generally away from the coast. A wave of low pressure then
possibly forms to our SW on Monday and shifts through during
Tuesday. This would bring overall higher chances of rain and
thunderstorms. So far it appears that Monday night and Tuesday
would bring the highest chances of rain. Highs Saturday through
Tuesday are expected to be near normal, but dewpoints remaining
around 70 will continue the muggy weather pattern.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
A trough of low pressure remains over the area into Wednesday
evening.

Mainly VFR outside of any convection. Exception is MVFR-IFR
conditions at KISP into Wednesday morning and MVFR fog possible
late tonight at KGON/KHPN.

Showers and Thunderstorms should exit city terminals by 3Z with
MVFR or IFR conditions. For now it appears convection should
miss KGON. For now appears convection will hold off tomorrow
until late in the TAF period at western terminals.

Will maintain vicinity mention, and add occasional thunderstorms
where appropriate based on radar trends. Will certainly update as
needed if a storm heads toward any particular airport.

Outside of any convection this evening, S-SW winds diminish to
less than 10KT tonight, with all but KJFK becoming light and
variable. S-SW winds (WSW at KSWF) up to around 10KT return by
around midday Wednesday.

KJFK TAF Comments: Amendments possible for convection until
around 03Z.

KLGA TAF Comments: Amendments possible for convection until
around 03Z.

KEWR TAF Comments: Amendments possible for convection until
around 03Z.

KTEB TAF Comments: Amendments possible for convection until
around 03Z.

KHPN TAF Comments: Amendments possible for convection until
around 03Z.

KISP TAF Comments: Amendments possible due to varying between
MVFR/IFR conditions. Also small chance amendments needed for
convection through 3z.

.OUTLOOK FOR 00Z THURSDAY THROUGH SATURDAY...
.Wednesday evening-Thursday morning...Scattered to numerous
showers/thunderstorms with MVFR or lower conditions possible.
.Thursday afternoon/night...VFR.
.Friday-Friday night...VFR. Isolated thunderstorms possible
late in the day and at night.
.Saturday...Chance of showers/thunderstorms with MVFR or lower
conditions possible.

&&

.MARINE...
Weak low pressure and an associated cold front will move slowly
through the waters tonight into Wednesday night. The low and
cold front then move east of the forecast waters Thursday.
Overall a weak pressure gradient is expected to remain across
the region through Sunday. Sea breeze development could locally
enhance winds near shore, but speeds should not exceed 15 kt.
Sub-SCA conditions continue during this time period.

&&

.HYDROLOGY...
Basin average rainfall Wednesday and into Thursday will range
from 1/4 to 1/2 inch. However, any shower or thunderstorm from
late Tuesday afternoon into Wednesday night, and then again
Friday night into early next week could produce locally heavy
rainfall and minor urban flooding.

&&

.TIDES/COASTAL FLOODING...
Astronomical tides will be increasing with the approach of a
new moon on Saturday. Coastal flooding will be possible with the
evening/nighttime high tide cycles Thursday through at least
Saturday. Although winds will be light, all that is needed in
most cases is around half foot or less of tidal departures to
reach minor coastal flooding. Areas that will be most
susceptible to minor flooding during this period are the south
shore back bays of Nassau, Queens and Brooklyn, Lower NY Harbor,
and portions of western Long Island Sound and perhaps along
Great South Bay in western Suffolk County. Minor flooding would
be most likely during Friday and Saturday night.

&&

.EQUIPMENT...
NYC NOAA Weather Radio Station KWO-35 (162.55 MHz) remains off
the air for an extended period of time.
