SYNOPSIS
High pressure off Nova Scotia shifts farther out into the Atlantic today as a cold front approaches the region from the west, passing through tonight. Behind it, weak high pressure briefly returns on Tuesday, before the front returns as a warm front Wednesday. A series of low pressure centers then impact the weather through Friday, and possibly into the weekend as well.
NEAR TERM /THROUGH TONIGHT/
In the wake of last night's rain, areas of fog have developed in parts of the region early this morning with weak flow and residual moisture, primarily across NE NJ, but eastward into southern CT and LI as well. While vsbys have largely remained above a quarter mile, locally dense fog remains possible for the next couple of hours and motorists should remain vigilant for quick changing conditions. Otherwise, the rain has tapered almost regionwide as the shortwave passes east, and the forecast remains on track.
Ridging and surface high pressure that was in place over the weekend has shifted well out into the Atlantic as a shortwave tracks through the Northeast and offshore as well. Meanwhile, a closed upper low swings into eastern Canada and will help send a cold front through the region tonight.
Temperatures jump 10 to 20 degrees compared to Sunday with ongoing WAA in the resulting SW flow, likely rebounding into the low to mid 70s away from the coast. Should more breaks in the cloud cover develop, temperatures inland could achieve mid to upper 70s.
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. 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 /12Z MONDAY THROUGH FRIDAY/
A cold front slowly approaches from the west, passing through tonight.
IFR or lower through the rest of the morning push, improving to low-end MVFR this afternoon for some terminals. IFR/MVFR this evening improves to VFR late tonight. Chance of a shower, mainly this afternoon. Iso TSRA potential late aftn/early evening as well, but but both threats with not enough probability and coverage to mention in TAFs.
Light and variable winds through the rest of the morning push, possibly favoring mostly NE to N. Winds shift more SW-W for the afternoon, but remaining under 10kt. Light N winds for late tonight.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Improvement to MVFR may be off by a couple of hours. Chance that KJFK remains IFR all day.
OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY...
Tuesday: VFR, becoming MVFR to IFR late at night with showers likely.
Wednesday: MVFR or lower AM, improving to VFR PM. Chance of showers.
Thunderstorms possible mainly in the afternoon.
Thursday: MVFR/IFR. Showers likely, mainly in the afternoon and night with an isolated TSTM possible.
Friday: MVFR/VFR with showers possible.

MARINE
Areas of fog have developed on the waters early this morning, and may be dense at times. Marine Dense Fog Advisory has been hoisted thru 13Z this morning for the LI Sound west of New Haven, the NY Harbor, South Shore Bays, and ocean waters between Sandy Hook and Moriches Inlet. Visibilities may drop below 1 nm before gradual improvement is expected late morning.
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.
MARINE...Dense Fog Advisory until 9 AM EDT this morning for ANZ335-338- 345-353-355.
