The surface low pressure continues to move northeast away from the area today. Forecast remains on track. The next round of pcpn is this aftn and eve as the airmass becomes unstable and the upr low approaches then tracks over the area. Maintained the sct wording in the fcst. Shwrs possibly transitioning to shsn with some ice pellets possible as well. Cannot rule out isold lightning strikes. Dropping temps late in the day with increasing W winds. H85 winds increase thru the day, reaching about 40kt by 00Z Mon. Sct-bkn clouds in the 4000-5000ft range should be a limiting factor for gust potential. As a result, expect winds to remain blw advy lvls today. Winds aloft gradually increase Sun ngt, but time of day and remaining high based low clouds should be at least subtle limiting factors. Have not issues a wind advy as a result. Temps today a mix of the NBM and NAMnest. The NBM was used tngt.

&& .SHORT TERM /MONDAY THROUGH TUESDAY/... Winds aloft increase further on Mon. By 00Z Tues, the NAM indicates over 60 kt at H85. With a well mixed and deep NW flow along with strong subsidence, this should set the table for over-performance of winds. Because of this, a high wind watch has been issued for the entire area. Despite the cold airmass, the deep mixing will allow for highs aoa normal. Wind chills however mainly in the 30s for the day. The NBM was used for temps. Ridging then begins to build in late Mon ngt into Tue. This will allow for the winds to finally begin to come down after midnight. For Tue, lighter winds and the start of a warming trend can be expected. After wind chills Mon ngt in the 20s and lower 30s, the NBM yields highs in the lower 60s for the usual swrn hot spots. These numbers were accepted for the fcst. Dry wx Mon-Tue. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... Key Points: * A warming trend takes place. For midweek, in response to the digging and amplification of the upstream trough over the Rockies a ridge builds across the East. This will lead to a warming trend with temperatures averaging well above normal for the mid and late week period with dry conditions. The trough will approach late in the week and likely bring another round of unsettled weather in the form of rain late Friday and Saturday with the arrival of low pressure and its associated occluded / cold front. There are differences in timing and in the handling of the Pacific branch and any potential interaction with the pure southern branch of the jet. Thus chose to take a consensus blend, which the NBM seemed reasonable with respect to PoPs for Friday and Saturday. The greatest deal of uncertainty deals with temperatures for Wednesday through Friday. By Thursday max temperatures are likely to get into the 60s across a good portion of the area, particularly away from the coast. If more of a westerly component to the wind develops closer to the surface, then temperatures could get even warmer than currently advertised. Some 70s therefore are a possibility away from the coast later in the week. && .AVIATION /14Z SUNDAY THROUGH THURSDAY/...

Deepening low pressure continues to lift north of the area through this afternoon and moves up along the Canadian border this evening. The low will track slowly east and northeast tonight into Monday. Ceilings have generally improved to VFR, but pockets of MVFR remain. There will be the chance of brief MVFR conditions this afternoon into early this evening in mainly scattered rain showers, with scattered snow showers possible across mainly western most terminals. Winds shift to the WNW this morning and gradually ramp up through tonight, with stronger winds and gusts coming tonight with gusts mostly around 35 kt, and occasionally near 40 kt. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Amendments are possible this afternoon and early this evening to refine timing of showers with brief and non-prevailing MVFR conditions. OUTLOOK FOR 12Z MONDAY THROUGH THURSDAY... Monday: VFR. W/NW winds 20-25kt gusts near 35-40kt. A few gusts 45- 50kt possible. Monday night: VFR. NW winds near 20 kt in the evening with gusts up to 40 kt, eventually decreasing to 10-15 kt with gusts 20-25kt late. Tuesday: VFR. NW winds 10-15G20kt. Tuesday night through Thursday: VFR.

&& .MARINE... Solid sca winds can be expected today, increasing to gale tngt and remaining thru Mon ngt. There is the potential for a few gusts to storm force on Mon. Winds and seas subside Tue, with all waters blw sca criteria by Tue ngt. More tranquil conditions are expected towards Wednesday and much of Thursday with light winds and ocean seas closer to 2 ft. && .HYDROLOGY... Although any pcpn amounts will be light today, some residual flooding of rivers and streams can be expected. No hydrologic impacts are expected tngt thru Fri. && .TIDES/COASTAL FLOODING...

The high tide cycle this morning will mark the last of the coastal flooding. Coastal flood Warnings for southern Nassau and southern Queens have been converted to an advisory, and advisories for Long Island Sound have been dropped. Advisories are in effect for areas adjacent to NY Harbor, including tidally affected rivers (Hackensack, Passaic, and locations along the Hudson), and all of the south shore of Long Island. A westerly flow should help to lower water levels across Long Island Sound, however, with a SE swell and high seas on the ocean, water will struggle to get out of NY Harbor and the south shore back bays of Long Island. There is always some uncertainty with the extent of this type of flooding as trapped water sloshes around in the bays and harbor. Preference at this time was to lean toward an ETSS and NYHOPS mean. The PETSS seems to be on the high side of guidance in a strengthening west flow. However, there is still the chance for localized moderate flooding across the south shore back bays, in particular across southern Nassau County.
