Area Forecast Discussion National Weather Service New York NY 337 PM EST Wed Jan 29 2020

SYNOPSIS. High pressure will build in from the north tonight and push off the New England coast Thursday night. Weakening high pressure Friday will give way to a coastal low pressure that moves well offshore into the weekend. Broad ridging into the beginning of next week will precede another area of low pressure approaching from the west by mid- week.

NEAR TERM /THROUGH TONIGHT/. High pressure will sink south from southern Canada. Subsidence associated with the high will allow for clear skies. With the pressure gradient weakening, winds will diminish, though slightly higher speeds expected along the coast. Regardless, it will be a decent night for radiational cooling. Lows will drop to the teens in the interior and Pine Barrens of Long Island, with 20s expected elsewhere. This is slightly below normal for this time of year.

SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/. High pressure pushes off the New England coast late Thursday into Thursday night. Near normal temperatures continue for Thursday, with highs in the middle to upper 30s. Thursday starts off mostly sunny, but clouds will increase, especially along the coast, making for a partly cloudy day by the afternoon.

Winds will shift from the north to the east, then southeast and south. However, most places will see light and variable winds overnight Thursday with the center of the high still so close to the forecast area. It will be another good night for radiational cooling, but with clouds increasing due to onshore flow, it will not be as cold as Wednesday night. Lows will range from the teens in the interior and Pine Barrens of Long Island, to the 20s to around 30 elsewhere.

LONG TERM /FRIDAY THROUGH TUESDAY/. As high pressure shifts off to the east on Friday, subtle ridging occurs over the Northeast as an area of vorticity deepens a trough over the Central US. Global models continue to be in agreement of a low pressure development off the Mid Atlantic coast early Saturday and into Saturday night.

A deepening trough over the Ohio Valley looks to remain positively tilted as it approaches the East Coast into the weekend. As an upper level jet stream intensifies over the Southeast, surface low development in the left exit region of this jet is likely ahead of the approaching trough. Exact track of the low pressure is still somewhat uncertain, but the GFS and ECMWF have been coming into agreement of a strengthening low that moves just to the south and east of the 40N 70W benchmark. With the forecast area in the NW flank of the system that remains well offshore, the chance precipitation has been trending less likely into the weekend. The best chance for any of the area to see precip would be coastal locations, though it is possible that the entire region remains dry.

With high pressure weakening ahead of the developing low pressure, there will be a lack of cold air over the region. As such, it is increasingly likely that any precip that does fall will be primarily rain with little chance of any accumulating snow with surface temps into the upper 30s and low 40s.

The low pressure rapidly intensifies as it moves to the northeast well offshore into Sunday. Southern ridging spreads eastward into Monday with above average temps into the beginning half of next week. The next system looks to approach the area from the west as an elongated area of low pressure that moves north of the region, but models have disagreement as to the exact timing and placement of the system.

AVIATION /21Z WEDNESDAY THROUGH MONDAY/. A large area of high pressure gradually builds in from the north through Thursday morning, settling across the terminals Thursday afternoon.

VFR.

NW to N winds 10-15 kt prevail through the remainder of the afternoon, with an occasional gust up to 20 kt possible at a few locations. Winds veer to the north and northeast, and diminish below 10 kt, early this evening and tonight. Northeast winds less that 10 kt Thursday morning become east to southeast in the afternoon.

OUTLOOK FOR 18Z THURSDAY THROUGH MONDAY. Thursday afternoon through Friday night. VFR. Saturday. MVFR or lower possible in rain and/or snow. Sunday. Becoming VFR early. NW winds G15-20kt possible. Monday. VFR.

MARINE. With high pressure over the waters and the pressure gradient weakening through Thursday night, winds and waves will remain below SCA criteria.

High pressure gives way to deepening low pressure tracking from the Mid Atlantic coast Saturday morning to south and east of 40N/70W Saturday night. This will keep the area on the NW fringe of the storm, with the potential for marginal SCA conditions. A better chance may come Saturday night into Sunday in post-storm westerly flow as seas build to around 5 ft. Lingering SCA seas on the ocean may linger into Monday, but look to fall below SCA criteria by Monday night.

HYDROLOGY. No hydrologic impacts are expected through Wednesday.

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.
