Area Forecast Discussion
National Weather Service New York NY
146 PM EDT Sat Jun 24 2017

.SYNOPSIS...
One cold front has passed east, and a secondary cold front will
pass tonight. High pressure will then build to our southwest
from Sunday into Monday. A cold front will move through later
Monday. High pressure will build toward the Mid Atlantic coast
Tuesday and Wednesday, before moving east on Thursday. Unsettled
will return for the end of the week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
After a busy morning, with heavy rain across NYC metro, Long
Island, and far SE CT, skies have become mostly sunny on a
drying post-frontal NW flow. NW winds were gusting as high as 30
mph in/near NYC, and look to do so into this afternoon.

Bumped highs up a little, with lower 90s in urban NE NJ,
mid/upper 80s most elsewhere, and upper 70s/lower 80s out east
along the coast.

Latest beach reports indicate high surf of 5-7 ft and dangerous
rip currents across Suffolk, so a high surf advy and rip current
risk statement have been issued.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
For tonight, a secondary cold front will move across, with winds
becoming more northerly late after its passage. Dry
conditions, light winds and continued mostly clear conditions
will result in radiational cooling. A vast range of lows will be
seen, from upper 50s in rural inland sections to lower 70s in
parts of NYC per NAM MOS guidance.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Dry conditions expected on Sunday as a ridge of high pressure
builds toward the Mid Atlantic coast. Expect high temperatures
to be in the lower/mid 80s on Sunday. A weak surface cold front
will affect the local area Monday afternoon into Tuesday. The
system will not have a great deal of moisture associated with
it, but cooler temperatures aloft may spark a shower or tstm
late Monday into early Tuesday. High temperatures on Monday and
Tuesday are expected to be from the mid 70s to lower 80s.

High pressure continues to build toward the area on Wednesday,
and slowly move offshore on Friday. A few showers are possible
Friday afternoon. High temperatures will start out near 80 on
Wednesday, then slowly increase to mid/upper 80s by Friday.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
A cold front pushes east of the terminals today. High pressure
builds into the region tonight and Sunday.

All the precipitation has ended across the terminals. VFR for
the remainder of the TAF period. Main headline will be the gusty
winds this afternoon. West-Northwest winds will gust to 20-25
kt, with some occasional higher gusts possible until 00z or so.
Winds diminish tonight with many locations becoming light and
variable. Seabreezes are expected to develop Sunday late
morning/afternoon.

.OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY...
.sUNDAY afternoon-Sunday Night...VFR. Afternoon seabreezes
expected.
.Monday...VFR. Coastal Seabreezes expected.

.MARINE...
Rough ocean conditions expected into tonight, with W-SW near
shore winds gusting to 20 kt. Winds in NYC metro are gusting to
25-30 kt, so also raised SCA for NY Harbor until around sunset.

&&

.HYDROLOGY...
Flooding threat has ended. See Public Information Statement for
area rainfall reports. No further hydrologic impacts expected
through the end of next week attm.

&&

.TIDES/COASTAL FLOODING...
Astronomical tides are running very high, especially during the
evening high tide cycles.

Less than 1 ft of surge is needed during these evening high tide
cycles for minor flooding, and in some cases less then 1/2 ft.
The expected S/SW flow is not favorable for surge, but a
background anomaly will likely be enough for minor coastal
flooding of the most vulnerable coastal locales along the south
shore bays of Western Long Island, along Jamaica Bay, and along
western Long Island Sound during this time.

&&

.EQUIPMENT...
KOKX weather radar will be down for maintenance. The radar
should return to service some time on Mon Jun 26.
