.SYNOPSIS...
-- Changed Discussion --
High pressure noses in from the north Sunday night through Monday as a low pressure system strengthens far offshore to our southeast. Weakening high pressure through the middle of the week gives way to low pressure passing offshore for the end of the week.

-- Changed Discussion --
The fcst is on track. High pressure continues to nose in from the north tonight with a building ridge aloft. At the same, a closed low and trough to our southeast will strengthen. This leads to continued breezy northeast winds from an increased pressure gradient this evening into tonight. This will prevent significant radiational cooling tonight. Lows will be in the low-30s to mid-20s.

The surface pattern remains the same for Monday. The high to the north will slowly shift farther north and the low offshore will weaken and shift farther southeast. The prolonged gusty northeasterly flow will continue through this Monday. Winds should remain below wind advisory criteria. Highs will be in the low-50s to upper-40s on Monday with lows Monday night in the low/mid-30s.

&& .LONG TERM /TUESDAY THROUGH SUNDAY/...
-- Changed Discussion --
High pres ridging swd across the area on Tue will gradually weaken thru Wed. At the same time, a deep marine layer is modeled to come in from the Atlc. The models are in good agreement with this. Ovc skies develop Tue with chances for light rain. Perhaps more of a sprinkles scenario. As winds decrease Tue ngt and Wed, better chance for light rain and dz to break out across the area. Kept the light rain and dz in the fcst thru Wed, then as then next upr trof approaches, transitioned to just rain chances Wed ngt thru Fri. This setup is progged to induce low pres development along the East Coast, with the lows or main low to track offshore and towards the N Atlc by Fri ngt. The prime window for rain is Thu and Thu ngt attm, but this could change depending on the speed of the upr trof. The models are in good agreement however, so stuck with the NBM pops which produces categorical on Thu. A more zonal flow aloft develops next weekend. This should be a dry setup at least Sat. Cannot rule out embedded energy in the flow producing some rain chances on Sun per the GFS, but there is not enough consensus among the other models at this point, so the NBM yields a dry fcst and that was accepted. The NBM with local adjustments was used for temps thru the entire extended.

&& .AVIATION /00Z MONDAY THROUGH FRIDAY/...
-- Changed Discussion --
High pressure builds in from the north through tonight, and remains through Monday. VFR. North winds gradually become more northeast late this evening and overnight, with speeds increasing along the coast. Gusts around 20kt are expected to develop on Monday, with the best chances at the coastal terminals. Also, winds and gusts will be the highest at the coastal terminals. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... No unscheduled amendments are expected. Gusts Monday may be as much as 5 knots higher at KJFK and KLGA. OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY... Monday night: Mainly VFR. Diminishing winds. Tuesday: MVFR with a chance of light rain/drizzle. There is a chance of IFR late in the day and Tuesday night. Wednesday: MVFR/IFR with a chance of light rain and drizzle. Thursday: MVFR/IFR with rain. Friday: MVFR with a chance of rain.

&& .MARINE...
-- Changed Discussion --
Increasing NE winds thru Mon. A SCA is in effect for all waters. Decreasing winds on Tue, but seas on the ocean will remain 5-10 ft. Seas continue to subside thru Wed, with waves on the ocean down into the 4-5 ft range for Thu. Increasing winds and building seas Thu ngt thru Fri with low pres tracking over the Atlc. There is a chance of gales especially Fri depending on the strength of the low.

&& .HYDROLOGY... No hydrologic impacts expected for the next 7 days. && .TIDES/COASTAL FLOODING... Astronomical tides will be increasing early this week with a full moon occurring early Monday morning. In addition, with low pressure remaining in the western Atlantic tonight into Monday and slowly weakening, long period swells will be moving into the waters, and winds will be from the northeast, both increasing water levels. Minor coastal flooding is looking less likely along the south shore back bays of Nassau and Queens during the Monday morning high tide cycle, so have held off on issuing an advisory or statement. Minor flooding is possible during the Monday evening high tide cycle, and this could occur from the south shore back bays from western Suffolk County westward all the way through NY Harbor. Not all guidance is in agreement on the chance or the magnitude of coastal flooding. For now, have issued a Coastal Flood Advisory for south Queens and south Nassau Bays with the chance to issue more should guidance come into better agreement, which would mainly hinge on how the offshore low trends. Shores along western half of LI Sound may also see minor coastal flooding, but have held off on issuing an advisory for now. Additional rounds of minor coastal flooding will be possible for all of the above mentioned locations for the Tuesday morning and nighttime tide cycles, with possibly parts of eastern Suffolk County reaching minor thresholds as well. && .OKX WATCHES/WARNINGS/ADVISORIES...
