Synopsis
A warm front passes tonight as high pressure remains to the
northeast. A wave of low pressure passes south of the area
Sunday into Monday. Meanwhile, a weak cold front drops into the
area Monday night and returns north as a warm front on Tuesday.

Another cold front approaches Wednesday and moves through
Wednesday night. High pressure then builds in for the remainder
of the week.

Near term until 6 am Sunday morning
Isolated convection has weakened. Still possible that high low
level moisture and ample instability could result in isolated
convection along any boundaries into the evening.

More organized convection ahead of shortwave moving across the
great lakes region toward northern new england will approach
northwest zones this evening. Will continue with higher pops
from nw, to lower pops southeast or coastal locations tonight.

As instability wanes, thunder chances will lower overnight.

Additional stratus development is expected tonight, with
coastal areas impacted once again. Patchy fog is possible. With
plenty of clouds tonight and continued light veering onshore
flow, temps will not vary much, upper 60s to lower mid 70s.

There is a moderate risk for the development of rip currents at
atlantic ocean beaches into this evening.

Short term 6 am Sunday morning through Sunday night
The area will remain between two upper shortwaves, one passing
to the nw, and another passing just south. A sfc low passes to
the south. Stratus will once again lift dissipate as the morning
progresses, and high humidity along with increasing
temperatures into the 80s will result in a hot day. Heat indices
will likely approach and in some cases exceed 90 degrees
Sunday.

Few to scattered showers and thunderstorms are expected once
again in this persistent pattern airmass.

Lows at night will remain in the 70s.

There is a low risk for the development of rip currents at
atlantic ocean beaches Sunday.

Long term Monday through Saturday
Hot, humid and somewhat unsettled weather will continue for the
first half of next week. Nwp is in good agreement with the overall
upper pattern across north america during the long term period, with
bermuda high pressure remaining in place resulting in gradually
rising heights across the northeast early next week.

Guidance has trended slightly lower with highs on Mon and as a
result confidence in a widespread 95-99 degree heat index
doesn't look as widespread as it did yesterday. Currently think
ne nj has the greatest potential to warrant a heat advisory
sun Mon but will let the mid shift have a look at one last round
of data. Pcpn associated with low pres passing well south of
long island on Monday appears to remain offshore, although a
trough of low pres developing north and west of nyc could
trigger isold showers tstms during the aftn eve with this threat
continuing through the overnight hours as a weak cold front
moves into the area. Humid conds then continue through wed,
although more cloud cover and increasing chances for pcpn is
expected to keep temps slightly cooler than Mon with less of a
chance of heat advsy criteria being met.

Heights will fall on Wed as the closed low moves into eastern
canada. Showers tstms develop as a result of a pre-frontal
trough Wed aftn and continue into Wed night as a stronger cold
front moves through. A dry and more comfortable airmass builds
in thereafter as high pres builds from the great lakes into the
weekend. Temps are expected to be near to slightly below normal
levels during this time.

Aviation 20z Saturday through Thursday
High pressure east of the new england coast will remain in
control through the weekend.

MostlyVFR, lowering to MVFR this evening with some ifr east of
the city terminals. Kjfk possibly lowers to MVFR ifr in fog
before sundown. TSTM could get close to kswf thru early evening.

Winds mostly SE 5-10 kt.

Outlook for 18z Sunday through Thursday
Sunday Chance of mainly afternoon and evening showers and
thunderstorms. Best chance north and west of the nyc terminals.

MVFR ifr ceilings improving through the morning.

Monday MainlyVFR. Slight chance shower or thunderstorm.

Tuesday-Thursday MainlyVFR. Chance showers or thunderstorms.

Marine
Easterly flow will veer more to the south by Sunday as a warm
front lifts, 10 kt or less. Seas remain under 5 ft on the ocean
and 1 ft or less across the non ocean waters.

Sub advsy conds are expected to prevail through the period,
outside of tstms. Seas on the ocean could approach 5 ft wed
night into thu, although feel that guidance was overdoing the
seas on SW flow so have knocked them down a foot for now.

Hydrology
No hydrologic impacts are expected at this time through the forecast
period.

Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.
