Area Forecast Discussion National Weather Service New York NY 340 AM EST Thu Feb 20 2020

SYNOPSIS. Weak low moves south of the forecast area today. Then as an upper level trough pushes offshore, high pressure builds into central New York State Friday. High pressure settles south of the area Friday night and Saturday, then slides east and offshore into the Atlantic on Sunday and Monday. Low pressure approaches from the south and west Monday night, with the low passing nearby on Tuesday. Weak high pressure returns for Wednesday before a strong low pressure system impacts the area on Thursday.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Shallow mid level trough axis pivots through the Great Lakes region and into southern New York today. The additional vorticity advection and lift should be enough to increase cloudiness during the day. But with precipitable water less than 0.25 inches, the atmosphere remains very dry with no rain is expected. Temperatures will be on the cool side and should reach the mid to upper 30s during the day or slightly below the daily normals.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/. Trough axis along the eastern coastline continues to shift east and offshore late Thursday night allowing a surface ridge to build into the region. North winds following a weak cold front bring even drier air into southern New York. Dew points overnight fall into the single digits. This coupled with relatively clear skies should permit temperatures to radiate into the mid teens over Long Island and low teens for the Lower Hudson Valley and southern Connecticut.

Mid level ridge axis extending from New England to the Lower Mississippi River Valley promotes subsidence locally keeping southern New York chilly and dry. Temperatures in the afternoon are expected to reach the mid 30s with clear skies persisting through the day time hours.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. Dry weather starts off the long term period as high pressure south of the region dominates. Expect dry weather Saturday, Sunday and most of Monday with temperatures above normal as high range from the middle 40s to lower 50s. Skies will be sunny over the weekend, however clouds begin to increase late in the day Monday as the next area of low pressure approaches from the south and west. Right now, this low is expected to pass west of the region, with temperatures warm enough for the precipitation to fall in the form of rain. There may be a few hours of a rain/snow mix well north and west of NYC, early Tuesday morning, however no accumulations are expected at this time. The low passes north of the region during the day on Tuesday, as it does, it will drag a cold front across the region, with precipitation ending from west to east during the afternoon.

Drier conditions are expected Tuesday night and Wednesday as high pressure briefly builds over the area. Another storm system is expected to impact the region Wednesday night into Thursday, however there remains some uncertainty to exactly the strength and placement of the next low. Right now, it appears that the low will track just south and east of Long Island, but remaining close enough for most of the area to see rain. As with any storm 7 days out, the exact track and strength of storm is expected to change.

AVIATION /09Z THURSDAY THROUGH MONDAY/.

VFR as high pressure builds from the west.

NW winds generally less than 10 kts into early this morning. City terminals will generally be 10-15 kts with possible gusts up to 20 kts. These winds will gradually diminish into the morning as high pressure builds in.

Otherwise, NW winds will back to around 310 magnetic increasing 10- 15 kts during the afternoon eventually shifting N/NW by this evening.

OUTLOOK FOR 06Z FRIDAY THROUGH MONDAY. Friday through Sunday night. VFR. Monday. Chance of rain with MVFR or lower flight cat, mainly afternoon/night.

MARINE. Weak cold front Thursday night into Friday passes offshore with winds over the ocean waters around 25-30 kts. SCA criteria winds should hold through the morning before diminishing in the afternoon. Waves should range 2 to 4 feet offshore through the short term.

Conditions are expected remain below SCA criteria through the weekend and into Monday across all forecast waters. The next chance of SCA conditions will be on Tuesday as a cold front pushes across the waters.

HYDROLOGY.

No hydrologic issues are expected.

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.
