Synopsis
A cold front slowly crosses the area this afternoon. High
pressure will briefly build into the region tonight and Monday,
before a weak frontal system affects the area from late Monday
night into Wednesday. High pressure returns to close out the
week.

Near term until 6 pm this evening
Forecast remains on track, with a few showers developing west of
the region and moving east. Minor updates with this afternoon
forecast to temperatures dewpoints to reflect current
observations.

Otherwise, a weak cold front slowly passes through the region
this aft eve. Sct showers and iso tstms are expected to develop
along the cold front, to the NW of the nyc metro, in a
marginally unstable airmass early this afternoon. This activity
should traverse eastward through through the afternoon. Some
uncertainty on extent of convective coverage with subsidence in
wake of morning convection and late approach of next piece of
shortwave energy. With marginally strong deep layer shear, a
conditional isolated strong thunderstorm with strong wind gust
is possible with if pockets of higher instability develop.

Expectation is for convection to weaken as it moves eastward
towards the coast in the late aft eve due to maritime influence.

Temperatures today will be above seasonable, well into the 70s,
except lower 80s for nyc nj metro.

Short term 6 pm this evening through 6 pm Monday
A couple of shortwaves move east through quebec tonight, with
zonal upper flow developing across the region into Monday. At
the surface, high pressure builds into the region through
Monday.

Clearing conditions expected tonight, with mostly sunny
conditions on Sunday. Temps tonight will be near seasonable,
with highs on Monday a few degrees above seasonable levels.

Highs generally in the mid to upper 70s, except lower 70s across
south coasts with afternoon seabreeze development.

Long term Monday night through Saturday
The upcoming week looks to be relatively benign with a weak
frontal system impacting the area late Monday night into early
Wednesday. There are some small timing differences with the
global models with both the onset of warm advection rain Monday
night and the possibility of scattered convection lingering
into Wednesday as the airmass change behind a cold front is
subtle. This does not look to be a significant rainfall event.

Additionally, while the westerlies and an upper trough will
remain across the area through midweek, the instability at this
time looks to be only marginal.

The second half of the week will feature building heights aloft
as the trough works offshore, resulting in dry weather and
above normal temperatures.

Aviation 18z Sunday through Friday
A cold front passes late this aftn.

MVFR CIGS improve toVFR this aftn. Iso sct shower or TSTM this
afternoon mainly after 19 20z. TSTM probability too low to include
in tafs at this time. Will go with vcsh for now.

Sw winds around 10 kt with gusts up to 20 kt bcmg W this aftn, then
finally NW early evening. Winds diminish tonight.

Outlook for 12z Monday through Thursday
Monday Vfr with light S winds.

Tuesday-Wednesday Most likelyVFR with low chance of MVFR in
any shower. S winds g15-20kt possible Tuesday afternoon.

Wednesday night-Thursday Vfr. N-nw winds g15-20kt possible.

Marine
Marginal SCA conditions are expected across the coastal ocean
waters into tonight, with sub small craft conditions expected
elsewhere.

A weak gradient is expected Monday through Wednesday, keeping all
waters below small craft advisory levels.

Hydrology
No widespread significant hydrologic issues are anticipated
through early next week.

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.
