Area Forecast Discussion
National Weather Service New York NY
153 PM EDT Fri Jun 29 2018
.SYNOPSIS...
High pressure will build to the west today into tonight before
the core of this high moves slightly offshore of the Carolinas
Saturday. The high remains across the region into early next
week. A weak cold front will slowly approach from the northwest
on Monday, move into the local area on Tuesday and then
dissipate on Wednesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Forecast on track. A few high clouds and fair weather cu will
otherwise be dominated by sunny skies. Dew points have begun
mixing out at most locations with the exception of the immediate
coast. JFK has had the winds shift to the SW with a bit of a sea
breeze, but NW flow may combat this and allow some of the
coastal areas to go back to the W or NW this afternoon.
The middle and upper ridge that will be responsible for the heat
wave is building aloft with heights rising through the rest of
the day.
Highs will top out in upper 80s and lower 90s. With lower dew
points in the low 60s, the heat index value will be close to
actual air temperatures.
A high risk of rip currents continues at the ocean beaches
today.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Tonight, the large ridge will continue to build into the region
with the upper level jet moving farther northeast into the
Canadian Maritimes. The surface high based in the Appalachians
will move towards the Carolinas. Flow is still mostly west to
northwest but decreases in magnitude. Subsidence will keep
clouds minimal again and with light winds, radiational cooling
will occur. Sided with a little warmer guidance, the MET
guidance, due to airmass coming in and the overall warm weather
pattern shaping up.
Saturday, the large ridge continues to build into the region. Models
show it growing to 594 DM just southwest of the region. Ridging
still very apparent as well at the 250mb level. At the surface, the
core of the high pressure area moves just offshore of the Carolinas.
The return flow will have more S-SW winds in the region developing
Saturday afternoon. This will result in slightly higher dewpoints
but still limited due to vertical mixing expected during the day.
The warmth of the airmass will be quite larger compared to the
previous day looking at model trends of about 4-5 degrees C higher
with 850mb temperatures. 850mb temperatures Saturday rising to 20-23
degrees C. Actual temperatures alone are in the mid to upper 90s
across Northeast NJ, the Lower Hudson Valley, NYC, and Nassau County
on Long Island. Combined with dewpoints a few degrees higher than
the previous day will result in these same locations getting heat
indices of 95 to 99 with some isolated 100 degree heat indices. To
the east, near 90 for highs with heat indices in the lower 90s.
The temperatures were taken from the MAV/ECS which featured
warmer temperatures, especially west of NYC.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Extended period of hot and humid weather expected...
Main concern during the long term period will be the prolonged
period of heat and humidity across the forecast area through
the middle of next week. A strong H5 (595dam) anticyclone over
the northern Mid Atlantic states Sat night will gradually lift
into southern New England early next week. Many locations,
especially away from the coast, will experience consecutive
days of 90+ degree temps with heat indices generally in the
95-105 degree range during this time.
Sunday appears to be the hottest day across the local area with
H85 temps of +22-24C progged. This will yield sfc high temps in
the mid to upper 90s inland (slightly cooler at the coast) and
corresponding heat indices in excess of 100 degrees. There is
the possibility that some locations reach heat indices of 105
Sun aftn, although if drier air at the top of the mixed layer is
able to mix to the sfc lowering dewpoint temperatures a few
degrees, they could fall short. Additionally, the NAM has the
higher H85 temps to our west which could result in lower air
temps and thus heat indices falling short of excessive heat
criteria. Due to these 2 factors, and the fact that it is a 5th
period event, will hold off on an excessive heat watch, but will
continue mention the low probability of excessive heat for NE
NJ, the Lower Hudson Valley and portions of NYC in the HWO. Day
shift will likely make the call on the watch this aftn, but note
that if a watch is not issued, advsy criteria will likely be
met for at least 2 consecutive days in the aforementioned areas
and the current hazard issued this morning would be extended
through Sunday.
The hot temperatures will decrease a few degrees each day Mon-
Thu, but the humidity will remain oppressive. As a result, heat
indices will slowly lower each day as well. The flow will shift
from SW on Sun to SE on Mon which will also draw in somewhat
cooler air at the coast from the waters. This is expected to
keep coastal locations (mainly eastern LI and SE CT) below heat
advsy criteria starting Mon. Otherwise, expect heat advisories
to continue for at least portions of the local area through the
middle of next week.
Dry weather is expected through Monday although a cold front
will slowly approach from the northwest early next week. The
front will drop into the local area on Tue and remain nearly
stationary into Wed before dissipating. This will provide a
trigger for showers and tstms, although at this point coverage
appears to be widely scattered at best due to the lack of deep
layered moisture. Have maintained slight to low chc PoPs Tue
through Wed. A weak shortwave could also trigger isold
showers/tstms on Thu.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
A broad area of high pres will build over the region thru Sat.
Mainly vfr thru the taf period, although there could be some
patchy fog at the outlying terminals in the 8-12z time period.
Nw winds today, except for sea breeze component flow along the s
coasts. As winds aloft increase this aftn, the flow in these
areas may veer further to the w again. Lgt and vrb flow on Sat
with sea breeze development.

The national radar mosaic for the moment the first event began.
1 heat. Local standard time, as filed.
A 71 year old man was found dead in the driver's seat of a vehicle at 345 pm in Whitestone. Hyperthermia was the cause per an autopsy. Heat indices were in the lower to mid 90s.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
