Synopsis for the long island and connecticut coastal waters - A weak cold front moves through the area tonight, followed by weak high pressure on Tuesday. The high gives way to an approaching warm front Tuesday night that moves across the area on Wednesday. A lingering frontal boundary south of the area Wednesday night into Thursday will eventually strengthen as low pressure approaches from the west. Low pressure moves across Thursday night into Friday. The low will be east of the region Friday night into next weekend.

SYNOPSIS
Offshore high pressure will shift farther out into the Atlantic today as a cold front approaches from the west and then passes through tonight. Weak high pressure briefly returns on Tuesday before the front returns as a warm front on Wednesday. A series of low pressure centers then impact the weather through Friday, and possibly into the weekend.
NEAR TERM /THROUGH TONIGHT/
What is left of a frontal boundary just south of the area will continue to dissipate while a cold front approaches from the west. Expect varying amounts of clouds with peaks of sun from time to time, especially across SE CT. Temperatures were varying quite bit due to differences in the cloud cover with the warmest conditions across LI and CT. Most locations away from the immediate coast are forecast to get into the upper 60s to around 70. This is a drop for some locations and a bump up for others. Max temps will likely need to be modified through the afternoon. Early spring can often be a challenge across the area due to low clouds and fog.
Meanwhile, a closed upper low swings into eastern Canada and will help send a cold front through the region tonight.
Can't rule out a few pop up showers in the afternoon, mainly across the interior, ahead of the trailing cold front, but coverage appears limited on CAMs at this point with weak lift and moisture. Maintained a low chance of a thunderstorm as well, but likely isolated at best.
For tonight, there could be redevelopment of low clouds and fog, especially across the coast. This is still being assessed as some drier moves in aloft ahead of the cold front. Low-level still may be moist enough. The front moves through tonight, and the flow veers NW as a result, bringing in drier air and decreasing cloud cover overnight.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/
Weak surface high pressure builds in from the Great Lakes behind the fropa on Tuesday. This should set up the clearest day of the week so far, with drier air working down in the northerly flow.
A mild afternoon for most with downsloping helping the interior and areas away from the coast to warm into the mid to upper 70s. Lower 80s possible in the urban metro of NE NJ. Much more sky than clouds should be apparent and sunshine prevails much of the day.
Thereafter, the front that pushed through Monday night stalls over the Mid Atlantic on Tuesday in zonal flow, returning to the region Tuesday night as a warm front as the high erodes and low pressure tracks into the Great Lakes. This will reintroduce rain chances by Wed AM, and perhaps some thunderstorms into Wednesday afternoon. Still a bit too far for our CAM coverage, so timing and coverage will need to be refined over the next day or two. SPC currently has the region outlined in a general thunder risk.
Wednesday is likely the hottest day of the week for at least portions of the area as the warm front attempts to lift north.
Exceptions may be eastern LI and southern CT, where onshore southerly flow will limit temperatures. Elsewhere, low 80s possible, with mid 80s into NE NJ. The attendant cold front passes through Wednesday night as the low exits to our east, but the pattern remains unsettled into late week as a wave of low pressure along the boundary to the south approaches thereafter.
LONG TERM /THURSDAY THROUGH SUNDAY/
Low pressure approaches from the Ohio Valley on Thursday with a secondary low center forming and passing over us or just off to our south Thursday night. As energy continues to transfer from the parent low to the secondary low center, a lingering trough between the two centers remains near the forecast area during Friday. Rain is likely Thursday and Thursday night, with still some chances of showers during Friday with moisture convergence along the trough along with some shortwave lift from aloft. An isolated rumble of thunder can't be ruled out mainly Thursday afternoon and evening as elevated instability will be present.
There's some uncertainty regarding the weekend, but overall there seems to be a model trend over the past day or two toward drier conditions. Although both days currently feature a chance of showers in the forecast, it can very well end up dry all weekend. There are indications of deep weak ridging for Saturday, then an area of low pressure that may pass too far to our south and west on Sunday to bring showers.
NBM was used for temperatures through the long term period. Cooler than normal through Saturday with a return toward more seasonable temperatures on Sunday.
AVIATION /18Z MONDAY THROUGH SATURDAY/
Offshore high pressure will shift farther out into the Atlantic today as a cold front approaches from the west and then passes through tonight. Weak high pressure will briefly return on Tuesday.
Some MVFR cigs are still hanging around the NYC metro area but should lift to VFR at some point late this afternoon. Sct late day showers could also produce MVFR vsby from the NYC metros north/west from about 21Z-24Z.
IFR/LIFR cond appear likely to return tonight to KISP/KGON, but the situation is highly uncertain for the NYC metro terminals.
Shallow moisture ahead of the approaching front could lead to redevelopment of low clouds/fog with MVFR or IFR conditions.
Confidence high enough to mention IFR cond for KJFK for a few hours (04Z-07Z) just ahead of the cold front, but these conditions could very well expand to the other metros as well as KHPN, and would be handled via later amendments if necessary.
After cold fropa, conds should improve to VFR from the NYC metros north/west, with N-NE flow less than 10 kt after daybreak Tue. Improvement to VFR will take longer farther east as winds after fropa will remain light until close to daybreak. Coastal sea breezes possible by late morning/early afternoon.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Low confidence fcst for tonight. IFR cond could begin sooner at KJFK this evening and also expand to the other terminals.
Unscheduled AMD likely.
OUTLOOK FOR 18Z TUESDAY THROUGH FRIDAY...
Tuesday afternoon: VFR.
Tuesday night: Mainly VFR. Chance of showers late with MVFR cond possible.
Wednesday: MVFR cond expected, IFR possible. Cond improving to VFR mid to late afternoon. Chance of showers. Tstms possible mainly in the afternoon.
Thursday: MVFR/IFR. Showers likely and possibly a tstm, especially in the afternoon and at night.
Friday: MVFR/VFR with chance of showers.
Saturday: Chance of showers with MVFR cond at KSWF, otherwise VFR.

MARINE
Dense fog advisory remains in effect for the ocean waters. The ocean waters may need to be extended into this evening.
Winds and seas are expected to remain below SCA conditions through Wednesday.
Easterly winds increase on Thursday, and this onshore flow combined with swell being generated from low pressure passing nearby is expected to build ocean seas to advisory levels starting late Thursday night into Friday morning, and lasting well into Friday night.
HYDROLOGY
There are currently no hydrologic concerns through this week.
TIDES/COASTAL FLOODING
Astronomical tides are running high with the approach of a new moon Tuesday night.
A statement has been issued for localized minor flooding with tonight's high tide cycle for Southern Fairfield County and the south shore back bays of Nassau County.
A more widespread minor flooding event that would necessitate advisories for these two locations plus Southern Queens will more likely occur with the nighttime cycles from Tuesday night through at least Thursday night. Statements for these 3 high tide cycles may be needed for other parts along western LI Sound, SW Suffolk County, as well as lower NY Harbor and Brooklyn.
OKX WATCHES/WARNINGS/ADVISORIES
CT...None.
NY...None.
NJ...None.
