Synopsis
Low pressure passes southeast of the waters through tonight. A
weak cold front approaches from the west Tuesday, then crosses
the area Tuesday night... Followed by another on Wednesday. High
pressure then builds to the south through Thursday night.

Another cold front approaches on Friday then slowly crosses the
area Friday night.

Near term until 6 pm this evening
The second of two vorticity maximums that led to the development
of rainfall across the area is moving through quicker than
previously forecast, so have adjusted precipitation chances
downward from west to east for this afternoon and evening
accordingly. Rain is currently tapering off across nj and
southeastern ny. Current timing ends the steadier rain across
eastern ct and long island by this evening by around 4-6 pm.

Water vapor imagery reflects subsidence aloft which will act to
strengthen the low level inversion, keeping moisture trapped
beneath the inversion amidst onshore flow. Expect a continuation
of cloud cover along with patchy drizzle and fog.

Unseasonably cool temperatures today as clouds and rain keep
temperatures in the upper 50s to around 60 for highs, some 10 to
15 degrees below normal.

There is a moderate risk of rip currents for area beaches.

Short term 6 pm this evening through 6 pm Tuesday
Frontal system pushes east of the area tonight, along with the
coastal storm. After some lingering showers early this evening,
conditions should remain dry. However, drizzle and fog may
persist overnight, with low level moisture trapped under an
inversion.

Another front approaches slowly from the west. Chances for rain
increase from west to east during the day Tuesday. Enough
instability for some thunder, but nothing severe expected.

Temperatures continue to be below normal.

Long term Tuesday night through Sunday
The models continue to have differences in how they handle the very
broad closed low that will be over SE canada Tuesday night through
Thursday night. As a result they also differ in the strength and
timing of shortwaves rotating around the base of the low, and hence
on the precise timing of precipitation during this time frame.

However, do have likely pops in for Tuesday night, as the models do
agree there should be some measurable rainfall across the region
then, but do have differences in timing during the night. Lows
Tuesday night should be a few degrees above normal.

For Wednesday and Wednesday night have mainly chance pops across
northern zones and slight chance pops across southern zones. With
showalter indices progged to 0 to -2, also have a slight chance of
thunder in for Wednesday afternoon and evening. Highs Wednesday and
lows Wednesday night should be a few degrees above normal as well.

Zonal flow sets up Thursday and Thursday night, and it appears the
region and with significant shortwaves progged to the NE and NW during
this time frame, have gone with a dry forecast then.

The model differences become even more noticeable Friday-Saturday.

For Friday, do have chance pops throughout by afternoon and continue
through Friday evening (along with a slight chance of thunder). Then
limit pops to slight chance from late Friday night-Saturday morning.

Then go with a dry forecast late Saturday Saturday night as both the
gfs and ECMWF show the core of the closed low to the NE then.

The new ECMWF has joined the 00z GFS in keeping Sunday dry, but
noting it previously had a coastal low approaching (now just
suppressed farther s), do have slight chance pops for Sunday.

Temperatures Thursday through Saturday night will feature near
normal highs and lows a few degrees above normal. Highs Sunday are
currently forecast to be a few degrees below normal.

Aviation 18z Monday through Saturday
Weak high pressure over the area will slowly give way to a
frontal system approaching from the west the next couple of
days.

This will keep the area under an easterly flow with low clouds,
fog, and a chance of light rain or drizzle.

Widespread MVFR conditions lower to ifr this evening, and
then gradually improve after daybreak Tuesday. There is some
uncertainty with ceilings and visibilities overnight due to
potential drier air in the low levels. This might result in
some variability in conditions this evening, but overall the
trend should be for lowering ceilings.

E winds this afternoon 5 to 10 kt, veer to the SE overnight at
at 5 kt or less. Winds may go light and variable.
