SYNOPSIS
A surface trough remains over the area today, while a weakening cold front approaches from the north. A series of waves of low pressure will then pass through the region Monday night through Wednesday night along a stalled frontal boundary. The boundary weakens and lifts north late Wednesday into Thursday. A cold front early on Friday. Weak high pressure should return late Friday into next weekend.

NEAR TERM /THROUGH TONIGHT/
Showers continue to work their way through the area, with this activity likely exiting to the east before 12z along with the associated shortwave. Skies clear this morning, before clouds partially fill back in by the late afternoon.

A dry day is expected for most. Although less aggressive than 24 hours ago, the CAMs still all show some convective activity this afternoon around northeast NJ, NYC and western Long Island near the surface trough axis. While a rumble of thunder can't be completely ruled out, thinking this activity will mainly be rain showers like yesterday given weak CAPE profiles. Any showers/thunderstorms associated with an approaching weakening cold front likely fizzle out before reaching the area, but can't rule out some sprinkles across the interior late in the day.

Temperatures today will be back to a few degrees above normal, in the upper 80s to low 90s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
Unsettled weather returns to the area on Monday. The region remains on the eastern side of a broad upper level trough, with multiple shortwaves moving through during this period. At the surface, a frontal boundary to our south crawls back north with a series of waves of low pressure forecast to pass near the area. This set up will bring chances of showers/thunderstorms the whole period.
Periods of moderate to heavy rainfall are likely possible, but it remains to early for any specifics on timing and areal coverage of this. See hydrology section below.

Temperatures will be a bit lower than today given the cloud cover and shower/thunderstorm activity, in the low to mid 80s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
A frontal boundary will stall and persist nearby for the mid week period. Expect rather warm and humid conditions with some unsettled weather at times. A few impulses of shortwave energy are suggested by global NWP leading to chance and likely PoPs for a good duration from Wednesday through late Thursday. PWATs are likely going to run at or just above 2 inches. Any embedded thunderstorm activity that occurs will likely lead to intervals of moderate to locally heavy rainfall. See the hydrology portion of the AFD for more information.

Weak high pressure likely returns either late Thursday night or during the day Friday and likely lasts into next weekend.

Temperatures through much of the period are likely to be near to slightly above normal, with more of a tendency for above normal temperatures for the night time due to high humidity and a tendency for clouds. Cloud cover should preclude the need for any heat headlines this week. Although, it may be close in the urban corridor if cloud cover ends up being less than currently anticipated during Wednesday and Thursday. The greater chance for headline heat and humidity comes towards late next weekend.

AVIATION /08Z SUNDAY THROUGH THURSDAY/
Weak high pressure remains in place today along with a surface trough through this evening. A frontal boundary weakens while drifting in from the north late tonight.

A few isolated showers are possible for eastern most terminals for the next few hours, but coverage is too low to include in the TAFs.
A few widely scattered to isolated showers cannot be ruled out W & N of NYC, but confidence in occurrence and location remains too low to include in the TAFs.

Winds will be light and variable and light from the WSW overnight into Sunday morning. The winds then will return to S at around 10 kt towards afternoon.

...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments are possible for any isolated showers that pop up Sunday.

OUTLOOK FOR 06Z MONDAY THROUGH THURSDAY...

Late Sunday night: VFR.

Monday: VFR. Potential MVFR towards late afternoon and evening in SHRA.

Tuesday through Thursday: Periods of MVFR or lower likely with SHRA/TSRA.

MARINE
With a weak pressure gradient over the area, winds and waves will remain below Small Craft Advisory criteria through Wednesday night.

More marginal small craft conditions due to seas is anticipated, especially further east on the ocean Thursday afternoon and night.

HYDROLOGY
The region will be in a humid and unsettled pattern towards mid week with anomalously high PWATs. Therefore at this time there appears to be at least a limited risk of localized flash flooding from any thunderstorms that produce heavy rain. WPC has placed our region in a Marginal Risk of excessive rainfall for Tuesday, Wednesday and Thursday. It remains too soon to lock down any details around hydrologic related impacts for the Wednesday and Thursday time frame.

TIDES/COASTAL FLOODING
There is a low risk for the development of rip currents at the ocean beaches today. A SE swell increases to around 3 feet at 10s on Monday resulting in a moderate risk of rip current development.

Minor coastal flood benchmarks may be approached along the western south shore bays of Nassau and Queens for the Monday and Tuesday night high tide cycles.
