SYNOPSIS
A cold front swings through for the first half of today as low pressure lifts north into Eastern Canada. A series of surface troughs will pivot through during the first half of the weekend.
A high pressure ridge briefly works in Saturday night into Sunday morning. A weak wave of low pressure will drag a warm front followed by a cold front through Sunday night into Monday morning. High pressure takes over Monday, potentially followed by a warm front front moving in late Tuesday into Wednesday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Another round of showers is moving through western portions of the forecast area. This is in association with a secondary cold front or surface trough. There may be an isolated thunderstorm that develops, with dew points in the upper 50s to lower 60s in this area, and some mixed layer CAPE in the 100-500 J/kg earlier.
However, models show this weakening as it heads east and lifts north, and mixed layer CAPE is decreasing. Ahead of this area of showers, dense fog had developed across New York City, central and western Long Island, and southwest coastal Connecticut. Visibility is improving in the city currently, and expect this to continue through the morning as showers help to mix out the fog. Any dense fog should dissipate by noon or prior.

The cold front pushes through eastern parts of the CWA by mid to late morning, and thus any organized rain should be mainly east and north by then. The winds will be rather gusty, but decrease some from their peak earlier. For a 3 to 4 hour period the winds relax some, but then pick up for the afternoon as a surface trough pivots through. Gusts up to 35 mph are expected after the trough passage as heights lower and more ideal mixing takes place across the area with steeper lapse rates. With spokes of energy wrapping in behind the departing low showers along with increasing frictional flow and cyclonic curvature look for some showers to pivot through. With the profile drying out in the lower levels any showers and drops that can make it down to the ground would have some higher gusts perhaps as an inverted V type profile attempts to set up. BUFKIT also hints at a little mid level CAPE, thus cannot rule out some low end low topped quasi-convective clusters. However, any activity would be isolated to widely scattered and mainly over western and northern sections. Despite a gusty SW flow providing cool air advection, temperatures will average above normal today with mainly lower and middle 60s for daytime maxes under varying amounts of cloud cover. Some upper 50s are more likely for eastern coastal sections.

The strong SW flow continues despite the loss of daytime heating tonight. The winds become more westerly gradually with time during the night, and even more so with the passage of another surface trough into early Saturday morning with falling dew points. Night time minimum temperatures will fall into the middle 40s to around 50 in most places with the wind and variably cloudy skies preventing any radiational cooling.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/
Spokes of energy aloft along with the passage of an additional surface trough will reinforce drier air at the surface and eventually cooler air into the start of the weekend. The main upper level trough pivots through early Saturday morning. With the instability and cooler air aloft expect a self destruct sunshine mechanism, with any breaks of sun and surface heating quickly leading to a good deal of clouds with a strato-cumulus combination at around 4 kft. Low end chance to slight chance PoPs for NW sections, otherwise expect mainly dry and blustery conditions. The winds will gust to around 35 mph across the CWA with good mixing with cold pool aloft and pressure gradient still in place on the back side of low pressure in Eastern Canada. Any showers may contain brief gusty winds, but much of the time it should remain dry with more of a classic V inverted profile. Much of the shower activity likely won't make it to the ground with more virga, than actual shower activity perhaps. Temperatures for Saturday will be cooler as 850 mb temps will be a bit below freezing. Temperatures will likely remain in the 50s all day across the entire CWA

For Saturday night after the last surface trough passage the pressure gradient will eventually weaken as low pressure gets well north into Eastern Canada. So expect the winds to diminish into the late evening and overnight hours. The winds will not completely shut off, but most locations will have gusts end as the night progresses.
With less in the way of cloud cover look for temperatures to be cooler, with night time lows mainly in the lower and middle 40s.

For Sunday the upper level flow becomes quasi-zonal with a high pressure ridge at the surface nosing in from the south. The day should be primarily dry, but clouds do increase in advance of a frontal system to the west and north. The front will be moisture starved, thus only chance to slight chance PoPs getting later in the day and mainly across the interior. The winds will be out of the SW ahead of the boundary, thus temperatures should get a bit warmer for later in the weekend as most places get back into the 60s, with perhaps portions of NE New Jersey pushing 70 as cloud cover may hold off long enough during the day.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Chance PoPs preceding a cold front for Sunday night with a chance of showers, along with perhaps some isolated thunder with some elevated instability being indicated by NWP guidance.
A due north cold front will clear clouds and precip Monday morning. The upper-level pattern remains zonal through Monday before a strong ridge builds Tuesday into Wednesday. This will lead to sunnier weather and temperatures warming into the mid-70s to upper-60s, supported by warm air advection aloft.

The ridge remains in place on Tuesday, though a strong upper-level jet develops aloft with a warm front placing itself over the area from a low in the northern Great Plains/Western Great Lakes. These will act together to increase cloud cover through the day on Tuesday, but expected warmer temperatures to remain due to warm air advection aloft. This warm front which eventually becomes a stalled boundary will lead to rain chances Tuesday night into Wednesday.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
Strong low pressure near the eastern Great Lakes will lift slowly north cross eastern Canada through the TAF period.

Improvement to MVFR and then MVFR/VFR is expected this afternoon with the wind flow becoming more westerly and allowing some marginally drier air to push in from the west. Spotty showers are possible but limited impacts at the terminals. On Saturday, low end VFR expected in stratocumulus cloud cover/ceilings. Spotty showers still possible Saturday mainly NW and W of the city terminals.

S-SW 15-25 kt winds with gusts 25-35kt becoming SW-W this afternoon and continuing into Saturday. Winds mainly W at the same speeds on Saturday gradually becoming W-NW.

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

Amendments likely for timing of improving categories and wind gusts.

OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY...

18Z Saturday: Chance of showers mainly NW of the NYC metros, mainly VFR. W-NW winds G25-35kt.

Sunday: Mainly VFR. Chance of MVFR and showers in the afternoon.
SW-W winds G20-25kt.

Mon through Wed: Mainly VFR. Slight chc of MVFR late Wed.

MARINE
A statement for marine dense fog that was issued earlier has expired. Conditions are starting to improve across the waters around New York City, and this is expected to continue through the rest of the morning. However, patchy dense fog may still limit visibility to 1 nm or less at times until noon.

Seas will be 10 to 15 ft out on the ocean today as gale force wind gusts give way to small craft wind gusts from west to east during the course of this afternoon and early this evening on a S to SW wind. Small craft conditions will linger through Saturday with a W wind with gusts mainly 25 to 30 kt, with occasional gusts to gale force out on the ocean. Ocean seas during this time will settle closer to 7 to 8 feet. More marginal small craft conditions are anticipated across much of the waters into Saturday night. Sub-SCA conditions are expected for most of Sunday with ocean seas mainly around 4 ft, with ocean seas get nudged back up by Sunday evening as a SW flow increases out ahead of a cold front. Sub small craft conditions are then likely to end by Monday evening with lighter winds and lowering seas into Tuesday.

HYDROLOGY
No hydrologic concerns exist throughout the forecast period.
