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/
A cold front will approach the region today and move across the area late this afternoon into this evening. Ahead of the front, a pre- frontal trough will develop.

PoPs will steadily increase this morning from west to east as showers continue to develop over eastern PA. Forecast guidance in good agreement that the shower activity will become more widespread as it moves into and across the CWA Most the of rainfall should be light although a few brief moderate showers cannot be ruled out.
Rainfall amounts will generally remain less than a quarter of an inch, except some spots could see up to three tenths of an inch across southeastern CT.

Improving conditions are expected late morning into the afternoon with the likelihood for some sunshine as clouds thin/diminish. Best chances will be west of NYC.

A pre-frontal trough over the area will keep the winds out of the W or SW for much of the day. This should allow temperatures to rise into the 60s for much of the area, with upper 60s to near 70 across portions of NE NJ.

The cold front moves across the area late this afternoon, shifting the winds to the NW, ushering in a cooler and drier airmass. A few of the CAMs are showing some isolated showers with the frontal passage late in the day. Chances for this are low and with the best forcing north of the region, will leave any mention out of the forecast.

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 /08Z SATURDAY THROUGH WEDNESDAY/
A surface trough approaches from the west early this morning and moves across the terminals through mid morning. A secondary cold front will move across the terminals this afternoon.

MVFR ceilings prevail across the terminals. Conditions lower to IFR early this morning as light rain showers develop. There is a low chance that a few terminals may briefly lower to LIFR, however, with low confidence have not included in the forecast. Conditions improve back to VFR mid-morning west, and during the afternoon east.

Light SE to S winds overnight become SW late/toward early morning, and westerly with the passage of the initial cold front. Winds then shift back to the SW before the passage of the secondary cold front during the afternoon where winds become more WNW with gusts developing. There is a chance that gusts will be around 25-30kt by late in the day with the secondary cold frontal passage. Gusts diminish into the first half of the overnight period.

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

Unscheduled AMD likely for timing of lowering conditions.
Uncertain with the timing of IFR into the early morning.

OUTLOOK FOR 09Z 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.
