Area Forecast Discussion National Weather Service New York NY 622 AM EST Wed Feb 19 2020

SYNOPSIS. High pressure will build in through Thursday. Upper level trough pushes offshore Thursday night as a surface high builds behind into central New York State. Dry conditions persist through the weekend. High shifts east Monday as the next low pressure system enters the region late Monday into Tuesday.

NEAR TERM /THROUGH TONIGHT/. Forecast is on track with only minor changes made to reflect current conditions.

Dry conditions return with clearing skies as high pressure builds into the area today. A surface trough/secondary cold front will move through late this morning into the afternoon, however, this will largely be unnoticed with perhaps a slight a slight lull in wind speeds before its passage and slight veering in the winds after its passage. Regarding winds, it will be rather gusty today as cold advection gets underway. NW winds will gust 25 to 30 mph, diminishing around sunset.

Afternoon highs will be a few degrees above normal, ranging from the upper 30s to middle 40s. Depending on the location, daytime highs may have been reached overnight last night.

SHORT TERM /THURSDAY/. With cold air advection continuing, colder air will finally make its way into the tri-state Wednesday night. Lows will be in the 20s region-wide, which is around normal for this time of year. Lower 20s are expected across the outlying areas. However colder temperatures are possible if winds diminish faster than forecast, allowing for more radiational cooling. If winds are stronger than forecast, then warmer overnight lows can be expected in these areas.

Temperatures will run below normal on Thursday with highs in the lower to middle 30s region-wide. A system will develop over the southeast U.S. on Thursday. With large high pressure continuing to build in, this system will pass well to our south and the northern fringes of any precipitation will be limited to the Delmarva Peninsula and points south. However, an increase in cloud cover can be expected.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. A dry pattern dominates through the majority of the long term period. Upper level trough pushes offshore Thursday night as a surface high builds behind into central New York State. This high brings very dry air into southern New York. Precipitable water falls below 0.10 inches throughout the air column and at the surface dew points are expected to be in the single digits for Friday. Temperatures will hover around freezing for the afternoon highs though breezy north winds will make it feel like the 20s.

Dry conditions persist through the weekend despite the mid level short wave that crosses Quebec Saturday. The trough has enough forcing to lift residual Pacific moisture for possible mid and upper level cloud development during the day. However, any rain will be unlikely. Ridge axis over New England shifts east Sunday allowing an established 1030mb surface high over the Mid- Atlantic to shift south of our forecast area. Meaning locally south to southwest winds return warming temperatures back into the upper 40s.

The high progresses east and offshore Monday as the next low pressure system enters the region late Monday into Tuesday. Global models haven't settling on the timing with this system. The Euro brings the initial warm front north over Long Island around 12 hours faster than the GFS with precipitation beginning Monday evening. This discrepancy in timing will have to be monitored closely as the system does have the potential to produce a wintry mix for the Lower Hudson Valley and southern Connecticut throughout its life cycle Tuesday into midweek next week.

AVIATION /12Z WEDNESDAY THROUGH SUNDAY/. High pressure builds in from the west today.

VFR through the TAF period.

NW winds increase 10-15 kt with gusts developing 20 to 25 kt by mid morning. Occasional higher gusts are possible especially during the afternoon. Wind direction will be frequently around 310 magnetic into late afternoon. Gusts subside after 00z, remaining NW around 10 kts.

OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY. Late Wednesday night through Sunday. VFR.

MARINE. SCA continues on the ocean waters with 5 to 6 ft waves expected. SCA on all waters starting noon today as NW gusts of 25 to 30 kt are forecast. Gusts diminish around sunset. Waves will also diminish late this afternoon, but will remain above 5 ft across the eastern ocean zone through this evening, coming down below 5 ft around midnight or so.

Winds and waves remain below SCA criteria on Thursday as the pressure gradient relaxes with high pressure building in.

Following a weak cold front winds out of the north Thursday night into Friday around 15-20 kts are expected to stay below SCA criteria

High pressure builds to the south through the weekend and winds shift westerly 10-15 kts.

Seas on the ocean waters remain below SCA around 2-3 ft and 1-2 ft within the Sound through Sunday.

Southerly winds develop Monday ahead of the next low pressure system though waves are still forecast to remain below SCA levels.

HYDROLOGY. No hydrologic impacts expected through Tuesday.

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

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
