SYNOPSIS
A cold front will move across the region late this afternoon into the evening. High pressure then builds in through early next week, then gives way to a frontal system on Wednesday.
High pressure then builds in again for the end of the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Pre-frontal trough continues to work its way across the area this morning. Showers accompanying the trough and lift aloft from an approaching jet streak will translate eastward through the rest of the morning. Most places along and west of the Hudson River corridor will be dry with the bulk of the showers occurring across Long Island and central/eastern CT.

Rainfall amounts will be light with potential of around a quarter inch across eastern Long Island/southeast CT.

Otherwise, already seeing clearing occur to our west and expect this drier air to work its way into the area late this morning and early afternoon. Winds will shift to the W by afternoon which will allow temperatures to rise into the 60s for much of the area, with upper 60s to near 70 across portions of NE NJ.
Did bump up temperatures on Long Island as the flow should mainly be W or just south of west with little influence from the cooler ocean.

The main cold front moves across the area late this afternoon, shifting the winds to the NW, ushering in a cooler and drier airmass. Winds may briefly gust 25-35 mph, especially west of the NYC metro. A few of the CAMs are also showing some isolated showers with the frontal passage late in the day. Have added in a slight chance of a shower across CT and eastern LI this evening, but most places will be dry.

SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/
The cold front continues to push across the area early this evening.
Any leftover isolated showers, should quickly come to an end. Behind the front, expect mostly clear skies with lows falling into the 30s inland and Long Island Pine Barrens and lower 40s closer to the coast.

A large upper level low will be developing over southeast Canada tonight into Sunday. This will result in troughing persisting over the eastern US early next week. A wave of low pressure is progged to develop over the southeast on Sunday along with another shortwave swinging across New England. These features will likely bring middle and upper level clouds on Sunday with partly to mostly cloudy skies and dry conditions. Highs will be a few degrees below normal in the upper 50s to around 60 degrees.

Surface high pressure then builds into the region for Monday and Monday night. Conditions will remain dry with highs on Monday in the upper 50s and lower 60s. Temperatures will fall into the 30s Monday night. Light winds and cold temperatures may result in some frosty spots well north and west of NYC.

LONG TERM /TUESDAY THROUGH FRIDAY/
A more zonal mid-level flow takes hold of the region by Tuesday with surface high pressure in place during the day. The next piece of energy embedded in a trough over the Great Lakes approaches the area on Wednesday. A low pressure system develops and passes north of the area pushing a cold front through the area Wednesday afternoon into Wednesday night. This brings the next chance for a round of rain for the area. The surface low moves northeast of the area on Thursday with high pressure building in from the west through the end of the week making for a fairly tranquil period.

Temperatures will remain at or below average for the extended period with highs each day in the middle 50s to low 60s.

AVIATION /15Z SATURDAY THROUGH WEDNESDAY/
A surface trough pushes east late this morning ahead of a cold front that moves across the terminals this afternoon. High pressure builds in tonight.

Rain showers are coming to an end from west to east, lingering only at KISP and KGON as of 15Z. This will come to an end everywhere by 16Z, with quick improvement to VFR thereafter.

Light SW flow may briefly become more W at the terminals late this morning behind the surface trough. Winds then expected to shift back to the SW into early afternoon before the passage of the cold front late in the day veers winds more WNW or NW with 20 to 25 kt gusts developing. Gusts diminish into the first half of the overnight period, with modest 10 kt westerly flow thru the remaining TAF period.

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

Unscheduled AMD possible for timing of category changes.

Isolated gusts to 30 kt late today and early this evening.

OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY...

Sunday: VFR. W winds G15-20kt in the afternoon/early evening mainly NYC metros/coast.

Monday and Tuesday: VFR.

Wednesday: Showers becoming likely. S winds 10-15G20-25kt mainly in the afternoon/evening, becoming NW at night.

MARINE
A cold front moves across the waters late today into this evening. Winds may briefly gust close to 25 kt near the NY Harbor and western Sound with the passage of the front, but it is not expected to last for many hours. No SCA has been issued.
High pressure will otherwise build tonight through Sunday.
Winds and seas are expected to remain below SCA levels given a relatively weak pressure gradient.

High pressure should keep conditions at sub-advisory levels through at least Tuesday night. Conditions may build back to SCA levels on Wednesday with the next low pressure and associated cold front to approach.

HYDROLOGY
No hydrologic impacts expected through next week.
