Area Forecast Discussion
National Weather Service New York NY
312 PM EDT WED AUG 10 2016
.SYNOPSIS...
Bermuda high pressure will remain across the Western Atlantic
through the weekend. A cold front approaches on Monday and moves
across Monday night into Tuesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The area will remain under the influence of Bermuda high pressure
through today with ridging over the northeast. A weak shortwave
and associated convective complex were moving through the ridge
and tracking across Connecticut and Long Island. Additional
convective vort maxima will move through the ridge today,
possibly increasing the chance of showers and thunderstorms again.
These storms will track along the periphery of the ridge with
the higher chances of precipitation across the lower Hudson Valley
into southern Connecticut. There will be little shear and steering
flow, with increasing isentropic lift, along with diurnal
instability. With a deep layered moisture influx from the Gulf of
Mexico there is the potential for areas of heavy rainfall as the
storms will also be slow moving.
The return flow around the high has already brought in higher dew
points in the low to mid 70s. The combination of temperatures in
the mid to upper 80s and dew points mainly in the 70s will result
in heat indices in the mid 90s. With the likelihood of heat
indices into the mid and upper 90s across NYC again Thursday, a
heat advisory remains in effect.
There is a high risk for the development of rip currents at the
ocean beaches this afternoon, due to long period southeast swells
and waves building to 3 to 4 feet. The risk may need to be
downgraded to moderate however with early reports coming in of
flat conditions in East Hampton. No changes will be made until the
full suite of observations come in.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Weak vort maxima continue to move through the ridge tonight,
however with the loss of heating and little forcing will lower
probabilities to slight chance later tonight. With a similar setup
for Thursday will increase probabilities to chance. And once again
moderate to heavy rainfall will be possible. With even warmer air
in the region for Thursday and combined with the high dew points,
heat indices across some interior locations may reach around 100
during the afternoon. Cloud cover and precipitation may limit the
warmup and with the uncertainty will not issue a heat advisory for
inland areas.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
There will be some persistent features Friday night through the
weekend. 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 through the
weekend, 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 the highest values forecast Sunday night into early
Monday.
These features will result in a continuation of the very warm and
humid conditions across the region. Dewpoints stay mostly in the mid
70s Friday night through the weekend. Max temperatures are forecast
in the upper 80s to lower 90s for a majority of the region Saturday
and Sunday and hence that is when the highest heat indices are
expected. Widespread upper 90s to around 100 degree heat indices are
forecast with some areas such as Northeast NJ and NYC possibly
seeing values reach near 105 degrees Friday and Saturday afternoons.
Portions of the Southern Connecticut river valley on Saturday
Afternoon with some pooling of dewpoints could also reach 105 degree
heat indices.
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 each day. 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 portend an increased flood
threat as thunderstorms will be slow moving. Relatively higher
chances are seen with showers and thunderstorms for Sunday and
Sunday Night so max temperatures that day will be lower, mainly in
the mid to upper 80s but still with the humidity, heat indices
will reach into the 90s for much of the region.
By early next week, the ridge will become more suppressed and an
upper level trough will approach from the west. This will allow for
lowering heights aloft with a cold front approaching at the surface
as the upper level jet starts to shift southward allowing for winds
to increase in the upper levels across the local area. The chances
for showers and thunderstorms will continue early next week and
could be more widespread. Again, heavy rain will be a factor with
any thunderstorms that develop due to the ambient tropical airmass
in place. However, there is increasing uncertainty early next week
in terms of timing of frontal features and precipitation with the
GFS showing a back door cold front moving in on Sunday and then
lingering that frontal boundary within the region. The ECMWF does
not show this, keeping flow from the SW with the cold front
approaching by Monday.
Both temperatures and dewpoints will be on a slight decreasing
trend for late Monday and thereafter through Tuesday. The frontal
boundary will be to the south of the region. However, the close
proximity of the front will allow for a continued chance of
showers and thunderstorms in the forecast.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
High pressure will remain offshore through the TAF period.
MVFR-VFR for the next hour or two, with the potential for IFR or
less in showers and thunderstorms east of NYC. Once the showers
move east, conditions are expected to return to VFR and we could
remain VFR through much of the TAF period.
There is a chance that conditions fall below VFR tonight in
stratus and/or fog, however confidence of occurrence is low.
Southerly winds increase through the day, 10 to 15 kt, with gusts
into the middle 20 kts. Winds will generally be less than 10 kt
in the city tonight, with light and/or variable winds elsewhere.

.OUTLOOK FOR 18Z Thursday through Monday...
.Thursday through Monday...Mainly VFR, with isolated to scattered
showers and thunderstorms, best chances in the afternoon/early
evening.
&&
.MARINE...
Bermuda high pressure will remain into the weekend. There will be
a persistent south to southwest flow across the waters today
through at least Thursday. At this time winds and seas are
expected to remain below small craft levels across the forecast
waters. However, there is a chance ocean seas may build to near 5
feet late Thursday. A weak disturbance moving through the region
will result in a chance of scattered showers and thunderstorms
today into this evening, and again Thursday afternoon.
All coastal waters are forecast to remain below SCA criteria
Thursday Night and the non-ocean waters will remain that way through
the weekend. However, for the ocean waters, there will be enough of
an increasing southerly fetch to allow for seas to build to 5-6 ft
Friday into Friday Night. The 5 ft seas then remain on the ocean
Saturday and Saturday Night. In addition, wind gusts will reach up
to near 25 kt on the ocean Friday and Friday Night before winds
return below SCA for the weekend.
&&
.HYDROLOGY...
Basin average rainfall of 1/4 to 1/2 inch is possible today into
tonight, with locally higher amounts possible. er amounts in
thunderstorms. An additional 1/4 to 1/2 inch of rainfall is
possible Thursday with locally higher amounts. The heavy rainfall
may result in localized minor flooding of low lying and urban
areas.
Scattered showers and thunderstorms Thursday night through Monday
will be capable of producing heavy rain. The thunderstorms Friday
night through early Monday will likely be slow moving, so there
will be the possibility of flooding with these.

GOODMANThe Brookhaven radar (KOKX), 50 km away, was scanning. The volume nearest the first event began at 20:02 UTC.
5 lightning, 2 thunderstorm wind, 1 tornado. Local standard time, as filed.
A house was struck by lightning on Bailey Avenue, between Knapp and Champlin Places, resulting in a fire. This was between Greenport and East Marion.
Trees and wires were reported down, blocking Lighthouse Road near Soundview Avenue, just east of Horton Point Lighthouse on the north fork.
Trees were reported down at the intersection of Mill Lane and Route 25, just east of Mattituck.
The National Weather Service in New York, NY confirmed a weak tornado near Mattituck in Suffolk County, New York on August 10, 2016.
Based on a survey conducted by an NWS Meteorologist, and information from NWS doppler weather radar data, emergency management, and trained Skywarn|spotters, the National Weather Service confirmed a weak EF0|tornado occurred in Mattituck, caused by a severe thunderstorm moving over the area.
Most wind damage was concentrated between Main Road and New Suffolk Avenue close to the corridor from Cardinal Drive southeast to Blossom Bend, where the tornado lifted before reaching New Suffolk Avenue. Wind damage was confined mainly to trees, where several trees were snapped in half.
Based on this limited damage, this tornado is classified as an EF-0 with wind gusts up to 70 mph.
A house was struck by lighting on Wells Avenue in Southold, causing a fire which destroyed the house.
A house was struck by lightning on Poplar Street, between Noyac Road and Benard Place in Noyack, resulting in a fire.
A house was struck by lightning on Union Street, between Madison and Division Streets in Sag Harbor, resulting in a fire.
