SYNOPSIS. A weak wave of low pressure passes offshore this morning. Arctic high pressure then builds across the region late today into Thursday. The high shifts offshore Thursday night. A low pressure system approaches from the south Friday. Rainfall becomes likely late Friday and overnight with an all day rain event expected through Saturday. The low exits to the northeast late Saturday into Sunday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Snow has moved well east of the area.

Clouds will gradually clear this afternoon, but some locations especially near the coast may remain mostly cloudy. Highs will generally be in the middle and upper 30s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/. A strong arctic high pressure builds into the region tonight and will settle over the northeast on Thursday. Most models have the high around 1040 mb as it settles overhead on Thursday. Upper trough axis swings across New England tonight with heights gradually rising on Thursday. NW winds will increase and gust 20-25 mph Wednesday night with clearing skies. Dry and cold conditions Wednesday through Thursday. Lows will fall into the teens inland and lower and middle 20s near the coast tonight. Wind chills will be in the teens. For Thursday, highs will be in the lower and middle 30s. Winds will be light with the high pressure overhead.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. Surface high continues to shift offshore Thursday night allowing for southerly winds to advect in moisture and comparatively warmer conditions headed into the latter part of the week. Overhead cloudiness returns to the Lower Hudson Valley and temperatures rise into the mid 40s for the day Friday.. There is a slight chance of warm frontal showers in the late morning with rain chances increasing into the late afternoon and overnight hours. These showers are associated with a deepening low pressure system off the Carolina coast. Southwest to northeast upper level flow over the eastern seaboard will spur this low north off the coast of Long Island through the overnight hours Friday into Saturday. Model soundings show the sub-tropical airmass has precipitable water values between 1.00-1.20 inches which will provide ample moisture for the expected rainfall. Timing has the majority of the rain falling for the NYC metro and surrounding areas in the overnight hours then lingering through the day Saturday. Rainfall totals around 1 to 2 could cause some instances of nuisance flooding in pour drainage areas.

Upper level trough axis pivots across New York state Sunday as a drier and more stable airmass moves into the region. Clouds clear out and temperatures are again the in mid 40s. Though overnight with the northwest winds, lows will fall near freezing around the city with areas north expected to be in the upper 20s prior to sunrise. High pressure builds Monday with more clear skies. This is short lived as an upper level jet stream of 150 kts over New England quickly transits the ridge axis eastward. The next low pressure system of note enters the Ohio River valley Tuesday morning. Global models show the possibility of mixed precip ahead of the system, but regardless could likely see another all day rain event for Tuesday.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/. High pressure builds toward the region tonight, and passes overhead Thursday.

VFR with clearing skies expected for the remainder of the afternoon. Skies will be mostly clear and Thursday morning.

Light N/NW winds will quickly back to the west and will increase in speed as the afternoon progresses. Winds turn toward the NW and increase further this evening. A few gusts 20-25 kt are possible. NW winds lighten later tonight and Thursday morning.

KJFK TAF Comments: Winds are expected to back to the west and increase late this afternoon.

KLGA TAF Comments: Winds are expected to back to the west and increase late this afternoon.

KEWR TAF Comments: Winds are expected to back to the west and increase late this afternoon.

KTEB TAF Comments: Winds will back toward the west and increase late this afternoon.

KHPN TAF Comments: Winds will back toward the west.

KISP TAF Comments: Winds back to the west.

OUTLOOK FOR 18Z THURSDAY THROUGH MONDAY. Thursday afternoon-Thursday night. VFR. Friday and Friday night. VFR on Friday, then MVFR possible in developing rain Friday night. Saturday. IFR in rain. LLWS possible. Sunday. Becoming VFR as rain ends. West winds 10-15 kt gusts 20-25kt. Sunday night-Monday. VFR.

MARINE. A weak wave of low pressure passes offshore this morning. Winds on the waters for much of today will be below SCA levels. NW winds start increasing late in the afternoon and will increase above SCA levels tonight as arctic high pressure builds to the west. Ocean seas will remain elevated through tonight as well. Wind gusts on the ocean could come close to gale force tonight, but should fall short. Have extended the SCA on the ocean through tonight and issued a new SCA for the non-ocean waters tonight. The waters east of Moriches Inlet could see seas remain elevated into the morning, so the SCA has been extended until 15z for now. Winds weaken considerably on Thursday as high pressure settles over the waters.

Low pressure approaches Friday and impacts the waters Friday night into Saturday. Marine zones could be nearing SCA conditions Saturday morning through the afternoon as south winds increase to 20-25 mph. A coastal low enters the ocean waters from the south and seas increase 9-11 feet by the afternoon. Elevated waves remain through Sunday then relax by early next week.

HYDROLOGY. No hydrologic issues are expected with mainly snow this Wednesday morning.

A long duration rainfall event is possible beginning Friday night through late Saturday night. Total rainfall amounts range between 1- 2 inches with isolated higher amounts possible. Minor nuisance flooding will be possible with this event.

TIDES/COASTAL FLOODING. There will be a chance of coastal flooding with the high tide cycle during Saturday morning. This will be due to onshore winds with an approaching storm combined with relatively high astronomical tides due to a nearly full moon. Minor coastal flooding will be possible primarily along the south shore back bays of Long Island, where even moderate coastal flooding is a possibility at least along the Nassau County bays. Minor flooding will also be possible along NY Harbor and parts of Western Long Island Sound. Confidence is not high at this point as the event is still a few days away, and shifts in storm's track and/or timing would change the flooding potential.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
