.SYNOPSIS...
High pressure will remain in control through the weekend. The
high will then slowly weaken as a frontal system approaches mid
to late next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Elongated E-W high pressure extending from Nova Scotia to the
Middle Atlantic will remain in control through tonight. Heights
aloft will slowly rise as ridging builds over the eastern US.

Some patchy river fog is possible early this morning.
Otherwise, mostly clear conditions are expected through
tonight. Temperatures should end up a few degrees warmer than
those observed on Friday with highs in the lower 80s for most
spots and middle 80s for the warmer locations in NE NJ and Lower
Hudson Valley. Another cool night is in store with a continued
dry air mass, mostly clear skies, and light winds. Temperatures
look to fall into the upper 50s to low 60s for most and middle
60s in the NYC metro.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
A high amplitude ridge (+2 to +3SD) over the eastern third of
the country will be the main weather feature into early next
week. Surface high pressure over the area on Sunday will shift
offshore and become more of a Bermuda high pressure system
Monday into Monday night.

Temperatures will trend warmer both Sunday and Monday. The latest
model consensus blend looks good with highs in the middle to upper
80s for most and low 90s in NE NJ on Sunday. Monday is looking to
feature more widespread low 90s away from the immediate coast with
middle to upper 80s near the coast due to the onshore flow
influence. The air mass will remain very dry with only a few clouds
each day. Dew points will be low enough (mid/upper 50s to low 60s)
to keep heat indices close to air actual air temperatures and
prevent them from getting higher than lower 90s. Nighttime
temperatures also gradually increase each night with patchy fog
possible.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
No significant changes made to the long term.

The high amplitude ridge in place across the eastern third of the
country will gradually break down through the period with the
westerlies sending a cold front through late Thursday into Friday.

Expect mainly dry conditions with increasing heat and humidity
Tuesday and Wednesday. Often, the NBM can be too high with dew
points and over the last couple of days it has adjusted dew points
slightly downward Tuesday. This likely due to its bias correction,
especially from recent performance. Regardless, there still remains
a chance for heat indices to meet heat advisory criteria,
specifically for the criteria of two consecutive day at 95 to 99.
The hottest day currently looks to occur on Wednesday with potential
of it continuing into Thursday. However, the areal coverage of 95-99
heat indices has been decreasing for Thursday. Temperatures during
this time will average 5-10 degrees above normal.

A late day shower or thunderstorm is possible mainly NW of NYC
Wednesday-Friday afternoons/evenings. Highs will generally be in the
upper 80s to lower 90s away from the Atlantic facing beaches with
lows in the 60s and lower 70s.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
VFR through the TAF period with high pressure remaining in control.

Light and variable winds overnight. Wash, rinse, repeat for later
today with light ENE winds to start in the morning, then becoming SE
at 10 kt or less from late morning into the afternoon.

&&

.MARINE...
High pressure in control will lead to conditions below SCA
levels through the middle of next week. A weak area of low
pressure well offshore may continue to bring an E swell into
early next week, but seas will remain below 5 ft.

&&

.HYDROLOGY...
There are no hydrologic concerns through next week.

&&

.TIDES/COASTAL FLOODING...
Easterly swells continue this weekend, but may start to subside
a bit on Sunday. A moderate rip current risk continues today,
but falls to low on Sunday with the subsiding swell.
