Area Forecast Discussion
National Weather Service New York NY
1259 PM EDT FRI AUG 12 2016
.SYNOPSIS...
Bermuda ridging will remain in control through Saturday
night...continuing oppressive heat and humidity over the Tri-
State Region. A cold front approaches on Sunday and moves through
the local area Sunday night into Monday. This boundary is then
expected to stall near the region...possibly through the middle of
next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Thunderstorms were just beginning to initiate at 1650Z near Port
Jervis. This trend should continue through the afternoon and
evening as CIN disappears east of the Hudson River. No major
changes were required to the forecast, however, low level
directional shear is noted on the KOKX VAD wind profiler, and VGP
for this afternoon increases from around 0.2 per LAPS to over 0.3
per the NAM by 00Z, so severe chances were upgraded on the
Enhanced Hazardous Weather Outlook.
The Bermuda high remains in place and aloft a ridge remains in
place with 500mb heights of 5900m to 5920m. Winds at the surface
remain from the S-SW. The upper level jet stays well north of the
region. Wind speed analysis at 250mb conveys that the wind speed
at that level stays below 30 kt. Layer precipitable waters will
stay between 2 and 2.5 inches across the region. With a continuing
SW flow, there will be further establishing of the hot and humid
airmass encompassing the region. Dewpoints stay mostly in the mid
70s. Temperatures rise well into the 90s, highest across NYC metro
and urban Northeast NJ and with dewpoints widespread in the mid
70s, areas within that urban region will have heat indices between
105 and 110 degrees with heat indices around 100 outside of that
urban region.
Diurnal instability and any differential heating due to cloud cover
in addition to sea breeze convergence boundaries will allow for
scattered showers and thunderstorms to develop, mainly in the
afternoon to early evening hours. In addition, any slight
perturbation and inherent subtle shortwaves along the periphery
of the ridge will easily allow for convective development with the
tropical airmass in place. Any thunderstorms during this period
will be capable of tapping into the rich quantity of atmospheric
moisture and thereby produce heavy rainfall. The aforementioned
lack of winds aloft will give a localized flood threat as
thunderstorms will be slow moving. Also, with inverted V soundings
and substantial moisture as well as steep low level lapse rate,
wet microbursts are also possible with some thunderstorms.
A borderline moderate to high risk for rip current development
continues through today with 3 to 5 southerly wind waves and
supplemental 1 ft long period se/e swells.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
Convection lingers into the evening and then decreases late at
night. Same scenario follows for Saturday and Saturday Night with
a persistent synoptic pattern as Bermuda high remains in control.
Peak of the heat appears Saturday with max temperatures slightly
warmer than today so heat indices in the 105 to 110 degree range
could potentially be seen across a larger area beyond the
Northeast NJ and NYC metro urban region. Elsewhere, heat indices
will be near 100 degrees Saturday.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
Oppressive heat and humidity continues through Sunday as Bermuda
ridging remains in control.
Temperature forecast for Sun is tricky due to the uncertainty with
the amount of cloud cover that will be present. Soundings are
indicating increasing mid and high clouds as a cold front approaches
from the NW...but the opacity is what will matter. Any breaks of sun
or even filtered sunshine could be enough for temps to be a few
degrees higher than forecast. But since there is some agreement in
thickening clouds...have lowered max temps a few degrees in spots.
Thus...max temperatures in the lower to mid 90s are expected for the
majority of the region Sun afternoon...with dewpoints in the mid
70s. Widespread heat indices 100 to 105 degrees are expected with
some areas such as Northeast NJ...NYC...and surroundings possibly
reaching or slightly exceeding excessive heat warning values of 105
degrees during the afternoon. Due to the uncertainty...will maintain
the spatial extent of the excessive heat watch on Sunday.
Low pressure will track through northern New England on Sunday
dragging a cold front towards the region. A pre-frontal trough
will develop Sun aftn with shower and thunderstorm development
expected once again as weak vort energy moving around the Bermuda
ridging...combines with with moderate diurnal instability...deep
moisture...and convergence along weak boundaries (pre-frontal
trough, seabreeze, outflow). This activity is expected to occur
mainly in the afternoon to early evening hours and for NYC metro
and interior. With a tropical airmass remaining in place...any
thunderstorms will have the ability to produce torrential
rainfall...and a weak steering flow will portend an increased
flash flood threat as they will be slow moving. A secondary wet
microburst threat will be present as well with deep moisture
aloft...steep low-level lapse rates and modest inverted V signature
at the surface.
Model trends of a slower frontal progression continue...with the
exception of the GFS which has been discounted. Thinking is that the
boundary will have a hard time progressing southward due to the
strength of the ridging over the western Atlantic. SREF/NAM and EC
are similar and follow this thinking therefore have maintained the
slower progression in the forecast.
Front slowly tracks through the area Sunday night into Monday
morning with shortwave trough approaching as well. Sct showers
and thunderstorms expected to continue overnight although higher
chances may end up being slightly further S than forecast.
Solutions continue to diverge early next week on southward
progression of the frontal boundary with Bermuda ridging slow to
relent. Confidence is increasing that the weak cold front may
becoming hung up over or slightly S of the area early into possibly
the middle of next week. This will maintain chance for scattered
shower and thunderstorm activity and a continuation of very warm and
humid conditions. 90 degree temps may continue for the NYC/NJ metro
into midweek, although not at the high heat and humidity levels of
the weekend.
Bermuda ridging appears that it may finally begin to break down late
in the week...allowing for a more seasonable airmass.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Patchy stratus may continue to result in brief MVFR CIGs of
1000-1500 FT, mainly at KGON. Otherwise, cloud deck will be FEW-
SCT010-015 through around 17Z.
Convection still possible across Lower Hudson Valley and southern
CT terminals by late afternoon, and possibly into KNYC terminals
by early evening. Confidence remains too low to reflect in TAFs at
this time.
SW winds 10-15 KT. Gusts to 20 KT for some terminals.
...NY Metro Enhanced Aviation Weather Support...
Detailed information, including hourly TAF wind component
forecasts, can be found at: http:/www.weather.gov/zny/n90
KJFK TAF Comments: No unscheduled amendments expected.
KLGA TAF Comments: Gusts might be only occasional.
KEWR TAF Comments: Gusts might be only occasional.
The afternoon KEWR haze potential forecast is GREEN...which implies
slant range visibility 7SM or greater outside of cloud.
KTEB TAF Comments: Occasional gusts 16-20 KT possible this aftn.
KHPN TAF Comments: No unscheduled amendments expected.
KISP TAF Comments: Gusts might be only occasional.
.OUTLOOK FOR 12Z Saturday through Tuesday...
.Saturday-Tuesday night...Mainly VFR. Isolated to scattered
mainly afternoon/evening SHRA/TSTMS each day may result in brief
MVFR or lower conditions.
&&
.MARINE...
For today and tonight, enough of a southerly fetch and a slight
pressure gradient increase will lead to more SCA conditions for
the ocean with non-ocean waters staying below SCA thresholds. The
non-ocean waters stay below SCA Saturday and Saturday Night. After
a brief return of the ocean to below SCA conditions Saturday, the
SCA conditions could potentially return for the ocean Saturday
Night.
SCA possibly continues on the ocean waters for seas into Sun night
before subsiding. Wind gusts may occasionally reach 25 kt Sun
aftn...but expect more frq gusts around 20 kt. Sub-advsy conds are
then expected through the remainder of the forecast period due to a
weaker pressure gradient.
&&
.HYDROLOGY...
With precipitable waters remaining generally between 2 and 2.5
inches, any thunderstorms that develop through the weekend will be
capable of producing torrential rainfall. With storm motion
generally expected to be less than 20 kt, there will be the threat
of localized flash flooding from any slower moving strong storm.
