.DISCUSSION...
.KEY MESSAGE 1...
Today was a mild day, but a warming trend will continue into mid-
week. High pressure at the surface is located very near the area
with riding continuing to build in aloft. This will keep skies clear
and allow for decent radiational cooling tonight with lows in the
50s.

Highs tomorrow warm into the 70s for much of the coast with the NYC
metro and interior areas N & W of NYC getting into the 80s. MOstly
sunny skies should hold as high pressure remains in control at least
through Tuesday night as it moves offshore.

.KEY MESSAGE 2...
A shortwave aloft will gradually traverse the region on Wednesday
and Thursday allowing for low pressure at the surface to impact the
region and bring chances for showers and even thunderstorms.

S to SW flow will lead to higher moisture transport into the area
with PWATs on both Wednesday and Thursday peaking between 1.5 to
2". For reference the SPC Sounding Climatology shows this is
essentially the 90th percentile to just above the max for this time
of year. Dewpoints also look to rise into the mid 60s to low 70s.
With a moist air mass in place and a passing shortwave aloft,
showers appear to grow in coverage west to east on Wednesday,
becoming likely by Wednesday afternoon. This will limit our
instability and high temperatures. This should mainly be a shower
event, but a few embedded thunderstorms could pop up on Wednesday,
especially in areas N & W of NYC.

Thursday appears to have a better potential for thunderstorms, along
with a risk for severe weather. The shortwave aloft moves to the
east with ridging building in from the west. This allows heights to
grow aloft on Thursday. Skies will clear out some with partly cloudy
conditions through the morning and early afternoon. However,
dewpoints and PWATs will be elevated Thursday afternoon and evening.
This occurs in tandem with very strong heating at the surface.

By Thursday afternoon, we should be primed for thunderstorms to pop
up in areas N & W of NYC, then pass eastward across the area into
the evening. With strong heating in place and only a weak cap,
thunderstorms could get started earlier than anticipated. The GFS is
bringing SBCAPE values as high as 2,600 J/kg in areas N & W of NYC
with values remaining above 1,000 J/kg as you get east of NYC, then
dropping altogether as storms advance east and evening takes over.
Bulk shear is not all that impressive around 15-30 kt, but mid-level
lapse rates reach 7.2 C/km on the 12Z GFS and 7.4C/km on the 12Z
NAM. Model soundings also show a good amount of turning of the winds
with altitude.

Details still remain murky this far out on severe thunderstorm
chances on Thursday until the event enters the time window of CAMs,
but at this point we`re keeping an eye out for growing potential for
damaging wind gusts and large hail. One thing that will really work
against them from developing is ridging aloft.

Any thunderstorms could bring with them heavier downpours, but they
should be moving fast enough to prevent any major concerns for
flooding. Our ongoing drought also helps mitigate flash flooding
concerns.

.KEY MESSAGE 3...
A 580-585 dam ridge takes over aloft Thursday into Friday under a
moist airmass with SW to S flow keeping dewpoints elevated. This
will allow high temperatures to climb into the 90s both days with
heat indices in the mid to upper 90s on Thursday. By Friday, western
parts of the area into the NYC metro could see heat index values
approach or exceed 100.

Rain chances should keep the period of higher heat confined to the
late morning and early afternoon on Thursday. Friday will be drier
with any rain not anticipated until at least Friday night with a
cold front, so heat could persist into the late afternoon.

.KEY MESSAGE 4...
A cold frontal passage is modeled to occur in the Fri night to early
Sat time period. This far out, timing is highly uncertain. However,
this timing will be critical, as an overnight passage will likely
have far fewer impacts than a Sat aftn passage. If the front slows
and does pass Sat aftn, a solid severe event seems likely.

Regardless of timing, the front will serve to cool temps down at
least a little over the weekend and into the start of next week.
Again, timing critical with Sat temps, but the model consensus is
currently quick enough to trend the numbers down. The current fcst
overall may be a bit too high based on the MEX, especially further
out where the NBM is about 10 degrees warmer on Mon.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
High pressure over the area will gradually sink south through
the day on Tuesday.

VFR.

S-SE winds around 10 kt will continue through this evening.
Winds back slightly to the SW tonight and weaken, becoming light
and variable at outlying terminals. SW-S flow at 10-15 kt
continues on Tuesday, with gusts to around 20 kt possible at the
city terminals.

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

No unscheduled amendments expected.

.OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY...

Tuesday night: VFR.

Wednesday: MVFR or lower possible in showers during the
afternoon/evening. Thunderstorms possible, primarily north and
west of the NYC metros. SW winds G20kt.

Thursday-Friday: MVFR or lower possible at times w/ chances of
showers and thunderstorms in the afternoon and evening.

Saturday: Generally VFR.

forecasts, can be found at: https:/www.weather.gov/zny/n90

.MARINE...
Sub-SCA conditions are expected to continue with high pressure in
control through tonight. The high pressure area moving farther
southeast into the Western Atlantic will make for more of a
southerly flow and fetch on Tuesday. The pressure gradient is
expected to tighten and with Ambrose jet likely to develop, western
ocean zones west of Moriches Inlet could gust near SCA levels for
some time late in the afternoon Tuesday into the early evening
Tuesday. Otherwise, sub-SCA conditions are forecast to continue
across the other marine zones. Sub-SCA conditions are
anticipated Wed-Thu.

Winds and seas are expected to remain blw SCA levels Fri thru the
upcoming weekend. There could however be strong tstms with a cold
frontal passage in the Fri night thru Sat time period.

Rip Currents...

For today, the rip current risk is moderate as winds gain a more
onshore component today near 10 kt with a lingering easterly
ocean swell of near 3-4 ft and 5 sec period. Wave heights are
expected to be near 3 to 4 ft.

For Tuesday, the rip current risk is also moderate. Southerly
winds of near 10 to 15 kts are expected with gusts near 20 kt.
Southerly ocean swells near 3-4 sec and easterly ocean swells
near 6-8 sec are expected with the southerly one increasing in
the afternoon. Wave heights of near 2 to 3 ft are expected.
