Synopsis for massachusetts and rhode island coastal waters.. A weak frontal boundary across new england combined with high pressure offshore, will provide weak sw winds across the ri and ma waters Saturday. Morning fog burns off and gives way to a mostly dry day. Low pressure approaches from the southwest Sunday and combined with high pressure over quebec, expect increasing ne winds along with rain Sunday across the new england waters. Low pressure then moves offshore Monday, with a drying and cooling trend, along with a wind shift to the north. A gale center may develop off the mid atlantic coast the middle of next week, then likely tracking well south of new england, but this system needs to be watched given some uncertainty.

SYNOPSIS
A developing low pressure over the Mid Mississippi Valley tonight heads up into the Great Lakes through Sunday, with a secondary low developing to the south of the area. Both lows lift north and east Sunday night into Monday. High pressure returns for Tuesday.
Another wave of low pressure develops off the Middle Atlantic coast Wednesday, followed by high pressure for Thursday. The next frontal system may move through the region next Friday or Saturday.
NEAR TERM /THROUGH SUNDAY/
With dense fog widespread and persistent across Nassau and Suffolk Counties, and dense fog likely to remain until rain arrives late overnight, have issued a dense fog advisory.
Updated for the dense fog across much of Long Island through 400 AM. A negating factor late overnight for the dense fog to remain will be an abundance of middle and high level clouds. Winds will also shift towards the E and NE and increase a bit near the coast as the low approaches. Once the rain moves in any lingering fog should improve.
Otherwise, dry conditions are expected through around 06z with rain overspreading the area from south to north through day break. Temperatures tonight will be in the mid to upper 40s.
A deep SW flow aloft and strengthening low-level easterlies across the area will result in a decent overrunning rain event through much of the day on Sunday with rainfall amounts mainly around 0.75 inches. Temperature highs on Sunday will be in the upper 40s inland and the lower 50s along the coast.
SHORT TERM /SUNDAY NIGHT/
A shortwave trough lifts from the eastern Great Lakes to east of New England Sunday night with drying conditions and a gusty west flow to follow. Temperatures Sunday night will be in the upper 30s inland and low to mid 40s along the coast.
LONG TERM /MONDAY THROUGH SATURDAY/
The forecast reasoning in the extended has not changed over the last 24 hours and the NBM was largely followed for this update.
The highlights for the long term are:
*Mainly dry conditions are forecast through the period.
*Temperatures will start out above normal on Monday before trending below normal to seasonable levels Tuesday through Friday.
The latest global ensemble means continue to agree on the large scale pattern for next week. A mean upper trough will remain over the eastern states Monday through Wednesday. The trough shifts offshore by Thursday. While it is about a week out, the ensemble means largely depict a shift towards ridging in the east and troughing out west by next weekend.
Low pressure will continue lifting northeast of the area on Monday.
Cyclonic flow aloft will likely yield mostly cloudy conditions, but temperatures will be above normal in the upper 40s to lower 50s. A weak cold front/surface trough will also move through the area. High pressure briefly returns on Tuesday. Another shortwave within the larger upper trough approaches late Tuesday. The shortwave will help amplify the trough as it pushes off the Middle Atlantic and southeast coast on Wednesday. The modeling continues to be in good agreement that the amplification will be too far east for any impacts from a low pressure developing off the Middle Atlantic coast. Have left in a slight chance PoP Tuesday night based on the model consensus, but any precip would largely be isolated. Colder temperature profiles would support some brief wet snow with potentially some rain mixed in over the NYC metro. These PoPs may need to be trended down in subsequent forecasts and conditions may stay dry Tuesday night and Wednesday given latest model trends.
The upper trough moves offshore Wednesday night into Thursday with heights rising into next weekend. High pressure returns on Thursday and may give way to a frontal system at the end of the week/next Saturday. The associated energy and shortwave passes well to our north, so have kept the forecast dry for now. The main theme heading into the end of the week and next weekend will be temperatures trending back above normal by next Saturday.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
Weak low pressure systems slowly approach from the southwest tonight, with the primary low reaching the eastern Great Lakes through Sunday, with a secondary low developing to the south of the area.
Flight categories vary from VFR across the inland terminals to IFR to LIFR at the coastal terminals. Inland terminals are expected to lower to IFR as fog and stratus develop this evening. Timing remains uncertain for the lowering conditions.
Conditions then remain IFR to LIFR through the night. There may be some slight improvement as rain develops late tonight, however, conditions will be mainly IFR. Improvement to MVFR is possible toward the end of the forecast period, as the rain tapers off. Again, timing remains uncertain, with uncertainty as to how how much ceilings and visibilities improve.
Winds will be generally light and variable until late tonight as low pressure approaches from the southwest, then a light NE flow develops, and strengthens Sunday morning. Removed the mention of gusts with low confidence that any gusts will occur. If any do will likely be occasional during Sunday morning.
...NY Metro(KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Timing of when MVFR and IFR redevelop could be off by 1-3 hours.
LIFR possible at times late tonight into early Sunday.
OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY...
Sunday night: Rain ending. MVFR to IFR improving late.
Monday: VFR. W winds G15-20kt, becoming more NW at night.
Tuesday: Mainly VFR.
Wednesday: Mainly VFR. N-NW winds G15-20kt afternoon into night.
Thursday: VFR. NW winds G15-20kt.

MARINE
With visibilities generally a quarter mile or less across the near shore waters surrounding Long Island and visibilities 1NM or less across Long Island Sound, and the ocean waters have issued a dense fog advisory through 12Z Sunday.
Otherwise, A strengthening easterly flow late tonight into Sunday will likely bring SCA conditions to the waters on Sunday and into Sunday night. Marginal SCA wind gusts are possible on the ocean on Monday with seas near 5 ft. 5 ft seas may also occur Monday night. Sub- SCA conditions are largely expected through Thursday although there could be some marginal SCA wind gusts on the ocean Wednesday night.
HYDROLOGY
Rainfall totals starting late tonight and into Sunday night will mainly be around 0.75 inches with no hydrologic impacts expected through next week.
