SYNOPSIS
High pressure builds in from New England today, then another frontal system tracks through Saturday night into Sunday. High pressure briefly returns Sunday night. High pressure then moves offshore early next week followed by a low pressure area moving across midweek. Weak high pressure returns thereafter towards the end of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Sky cover has been a tricky one to forecast today, so have increased it in some areas and decreased it in others for the remainder of the morning. Patchy dense fog is also being observed across interior portions of west CT, NE NJ, and the Lower Hudson Valley. This should continue until around 8 am.

Mid-level heights increase today under a weak ridge with anomalously low heights along with surface high pressure nosing in from New England. It should allow for more sunshine today, but it will only be brief before troughing sets back up this evening from the west.

Given the anomalously low heights, cooler air will remain in the region today with highs only expected to reach low-60s. Some near the NYC metro may reach the mid-60s while other the immediate coast of Long Island and Connecticut may only reach the upper-50s. These temperatures are about 5-10 degrees cooler than average.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/
With troughing increasing from the west with an approaching frontal system in the Great Lakes, cloud cover is expected to increase Saturday evening into Saturday night. PWATs of 1"+ will also be advected in from the west with positive vorticity advection and warm air advection aloft both occurring, aiding in the formation of clouds and eventual rain.

The trough will guide a weakening frontal system into our area overnight Saturday with an occluded front. Rainfall will start in the west overnight and spread eastward toward daybreak and into the morning. Given the weakening nature of the system, most of the rainfall will likely occur over far western sections of the area with much lighter precip expected for the rest of the CWA due to weaker forcing. Some may only pick up a trace or even remain dry (in eastern areas), while those in far western sections of our CWA could see around a quarter inch.

No thunderstorms are expected due to a stable environment.
Temperatures will be cooler on Sunday from the influence of the trough, cloud cover and rain. Highs are expected to be in the mid- 50s, around 10-15 degrees below seasonal norms.

Expecting slow improvement Sunday afternoon and evening as high pressure returns once again with weak ridging aloft increasing from the west. Given the weak high taking over and the weak departing low, the pressure gradient will be weak, meaning mostly light winds Sunday night. And with the high pressure clearing clouds, could expect some weak radiational cooling. Lows are forecast to be in the mid/upper-40s with the LI Pine Barrens and interior areas in the low- 40s.

LONG TERM /MONDAY THROUGH FRIDAY/
In the mid levels, ridging early next week will be followed by a trough moving in for midweek. Model differences with timing and evolution of trough with ECMWF showing a cutoff low. ECMWF keeps a slower movement of the cutoff low while the GFS and Canadian models depict a faster more progressive trough shifting more east of the area towards the end of next week.

At the surface, high pressure based in the Atlantic will allow for more southerly flow to develop early next week. Low level warm air advection is forecast with a warming trend to daytime temperatures from Monday to Tuesday. More easterly component of flow develops for midweek as low pressure approaches from the west. Like the midlevels, differences become more apparent in model solutions regarding the speed, location and strength of the low. ECMWF lingers the low nearby for Thursday and Thursday night while the GFS and Canadian models show the low moving farther east of the region. Weak high pressure follows for Thursday into Friday.

Next substantial rain event depicted in the general Tuesday to Wednesday night timeframe. Tuesday night and Wednesday could present some embedded thunderstorms, with a slight chance with elevated instability and colder air aloft moving in.

Temperatures mainly near to above normal during the long term.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/
Weak high pressure initially will give way to an approaching weak frontal system tonight into early Sunday.

Outside of some localized IFR to sub-IFR conditions before 12Z today, mainly VFR conditions are expected through the TAF period.

Winds will be near 5 kts or less into early today with variable direction for interior locations but more northerly along the coast. Winds then become more east this morning with more southeast winds developing this afternoon into tonight. Wind speeds will be generally near 5-10 kts.

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

IFR to MVFR conditions at KTEB could linger until around 12Z this morning.

Otherwise, for KEWR, KLGA and KJFK, mainly VFR conditions are expected during much of TAF period.

OUTLOOK FOR 09Z SUNDAY THROUGH WEDNESDAY...

Late Tonight: Chance MVFR and showers late at night.

Sunday: Chance of MVFR or lower in showers.

Monday: Mainly VFR. Isolated showers possible at KSWF.

Tuesday: MVFR or lower in showers. T-storms possible at night. S-SW wind gusts 15-20 kt.

Wednesday: MVFR or lower in showers and t-storms. SE to NE wind gusts 15-20 kt.

MARINE
Winds and seas should remain below SCA levels this weekend.

Mainly below SCA conditions forecast Monday through Tuesday with more probable SCA conditions for midweek.

HYDROLOGY
No significant hydrologic problems anticipated.

TIDES/COASTAL FLOODING
Many locations are expected to fall short of minor coastal flood benchmarks for high tide cycles tonight. However, the South Shore Bays of Nassau County NY could have some locations that touch or slightly exceed their respective minor coastal flood benchmarks. Winds are expected to transition to more of an onshore flow later today into tonight. A coastal flood statement has been issued for Southern Nassau County between 9PM EDT this evening and 1AM Sunday EDT overnight to address the minor coastal flooding.

With astronomical tides continuing to lower for the rest of this weekend and into early next week, no coastal flooding at all is expected for this timeframe.
