Area Forecast Discussion
National Weather Service New York NY
211 AM EDT Sun Jun 18 2017
.SYNOPSIS...
A warm front dissipates across the area tonight. A slow moving
cold front begins to approach the region on Sunday night,
crossing the area Monday night into Tuesday. Weak high pressure
builds in Tuesday night, followed by a series of weak frontal
system mid to late week.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A weak warm front washes out across the region overnight.
Expecting to see the same trend over the next few hours with
scattered showers and an embedded thunderstorm developing over
eastern PA/central NJ and weakening as it pushes north towards
us, being in a more stable airmass. A few heavy downpours and
localized minor urban flooding not out of the question tonight.
Otherwise...no discernible focus or trigger for shower/tstm
development overnight...but can't rule out additional isolated
activity with any weak vorts moving through in this tropical
airmass.
Very warm and moist airmass over the region tonight with lows
temps and Tds generally in the upper 60s to lower 70s.
Maintenance of low stratus is expected in this
environment...with potential for locally dense fog once
again...particularly along the coast.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/...
Region will continue in a tropical maritime airmass Sunday
through Monday Night in between strong Western Atlantic Ridging
and a large closed low over Ontario and its associated longwave
trough deepening east of the Mississippi River valley.
PAC energy entering the NW coast today appears to be main forcing
for a developing shortwave trough to rotate around the longwave
trough and pivot towards the region Monday into Monday Night and
then through on Tuesday. At the surface...resultant low pressure
develops over the Upper Great Lakes Sat Night/Sunday and then stacks
under the upper low near Hudson Bay early next week. Its trailing
cold front will slowly cross the Ohio Valley Sunday into Sunday
Night...and then push towards the coast Monday into Monday
Night...before eventually pushing east on Tuesday.
Very warm...moist...and unstable airmass expected in this
pattern Sunday and Monday. High temps will generally be in the
80s each day...with any breaks of sun on Sunday and Monday
allowing temps to rise well into the 80s away from the coast.
Heat indices will likely be in the upper 80s to lower 90 degree
range for NYC/NJ metro and points N&W Sun and Mon.
Convective activity on Sunday still looks to be confined to NYC
metro and more so points N&W. Moderate instability development
likely with afternoon break of sun across this area. Coverage
and intensity of convection will be predicated on any shortwave
energy moving through the flow...but at this point with main
synoptic forcing well to the west expecting coverage to be
isolated along any differential heating boundaries or higher
elevation. Marginal deep layer shear with instability looks to
be conditionally supportive of isolated strong to severe wet
microbursts. Additionally...a low and localized flash flood
threat exists with any training tstm development in deep SW
flow.
Have sided with limited convective coverage Sunday
night with weak instability and cold front/pre-frontal trough
still to the west and lack of discernible focus/trigger for
convection. Otherwise warm and muggy night with stratus
development likely. Stronger low-level winds may limit fog
development.
Synoptic forcing steadily increases Monday into Monday night with
approach of shortwave trough axis and falling heights, right rear
quad of 100kt jet, 35-45kt llj and of pre-frontal trough/cold
front. Widespread shower and thunderstorm threat becomes likely
for NYC metro and point N&W for Monday aft/eve due to increased
large scale forcing and pre-frontal trough/cold front entering
the area...interacting with the moist/unstable airmass in place.
The increased convective coverage in this area will increase
the threat for flash flooding as deep sw flow aligns with
surface fronts and is conducive to training convection. Severe
threat also exists for Monday aft/eve for NYC metro and points
N&W with deep layer shear likely increasing to moderate levels
and at least moderate instability levels developing with any
breaks of sun. Initial mode may be more discrete cells...then
transitioning to line segments or possibly QLCS later in the
afternoon/evening. Main severe threat will likely be for wet
microbursts with either mode...with threat for large hail with
any discrete convection. Isolated tornado threat not out of the
question as well with either mode due to relatively low-lcls and
where low-level winds are locally more backed.
Convective severity should diminish Monday Night as instability
wanes and convection translates eastward into more stable maritime
layer across LI/CT. Exact timing of shortwave axis and
associated frontal passage Monday Night into Tuesday morning
will determine when threat for showers and thunderstorms finally
moves east, pushing the subtropical airmass offshore. At this
point...the threat for shower and embedded tstms could continue
across eastern LI/CT into early Tuesday morning.
A high risk of rip current development is expected for much of
the Atlantic beachfront Sunday into Monday as southerly swells
and wind waves build into the waters. The high rip conditions
are likely into Tuesday.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Western Atlantic ridging breaks down enough to allow broad
upper low over Ontario/Quebec to begin sliding east during the
midweek. It associated trough axis slides across the region on
Wednesday. Although tropical airmass will be shifted offshore by
this time...weak diurnal instability will bring chance for a
few showers and possibly a thunderstorm Wednesday afternoon and
evening.
High pressure briefly builds over the region on Thursday as the
flow aloft becomes more zonal. This will allow for a return of
heat and humidity by weeks end. Potential for a series of weak
shortwaves to ride through the upper flow Thursday and
Friday...timing/intensity of which will determine potential for
aft/eve shower/tstm both days.
Thereafter...model spread exists on evolution of longwave
troughing for the northern and eastern US for the weekend. The
magnitude of which will determine sensible weather.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
High pressure builds in from the southeast into tonight.
IFR/LIFR conditions this morning, improving to MVFR (KGON/KISP)
to VFR (elsewhere) this afternoon. Conditions probably return to
MVFR or IFR (most likely KGON/KISP) this evening. Spotty showers
are possible early this morning. Isolated showers and
thunderstorms are possible mainly west/north of the city
terminals this afternoon. Confidence in any
showers/thunderstorms is too low to reflect in the TAFs at this
time.
SE-S flow at under 10kt this morning, becoming S throughout at
10-15kt this afternoon. Should see some gusts of 15-25kt for all
but CT terminals, highest gusts at KJFK/KISP/KLGA. Gusts should
abate early this evening, with winds veering slightly to the SSW
at most terminals, with speeds remaining around 10-15kt.
LLWS is probable at city/coastal terminals this evening.
.OUTLOOK FOR 06Z MONDAY THROUGH THURSDAY...
.late tonight...MVFR or lower possible. LLWS probable.
.Monday-Monday night...MVFR or lower possible. Showers and
thunderstorms likely - with some storms possibly strong to
severe. LLWS probable, with best chance at eastern terminals.
.Tuesday...Becoming VFR during the morning. Lingering showers
possible early at eastern terminals. SW-WSW winds G15-25kt
possible in the afternoon.
.Tuesday night...VFR. W-NW winds G15-25kt possible.
.Wednesday...Most likely VFR. A brief period of MVFR is possible
with any shower and/or thunderstorm.
.Wednesday night-Thursday...VFR. SW winds G15-20kt possible
Thursday afternoon.
&&
.MARINE...
A dense fog advisory has been issued for all waters tonight as
conditions are favorable for dense fog development. Visibilities
may improve overnight once warm front dissipates...if not it
will take until Sunday morning.
A relaxed pressure gradient will limit the winds on all
waters into tonight...but marginal SCA winds expected to
develop on ocean and possibly on all waters Sunday
afternoon...continuing into Monday night.
Persistent SSE-SE winds should have swells building to 4 to 6
ft on ocean waters tonight...with seas gradually increasing
through Monday to 5 to 8 ft.
The pressure gradient relaxes on Tuesday in wake of cold front,
with winds diminishing to 10 kt or less on all waters by late
on Tuesday, with the relatively light winds continuing on
Wednesday. Seas however should remain up to 4-7 ft on the
coastal ocean waters through most of Tuesday with residual
southerly swells, then fall below SCA levels Tuesday night and
remain below on Wednesday.
&&
.HYDROLOGY...
No large scale hydrologic impacts are expected through Sunday
evening. There is a low and localized threat for flash flooding
on Sunday Aft/Eve from training convection for NYC and points
N&W.
The potential for flash flooding increases Monday afternoon
into Monday evening due to likelihood for widespread shower and
thunderstorm coverage and potential for training of this
activity. A widespread 0.5-1.5 inches of rain is expected to
fall across the area, with higher amounts in path of any
training thunderstorms.
&&
.EQUIPMENT...
* Meriden NOAA Weather Radio, WXJ-42, is off the air. Return to
service is possible by Sunday.
