Area Forecast Discussion National Weather Service New York NY 903 AM EST Fri Feb 21 2020

SYNOPSIS. High pressure drifts slowly to the south of the area through Saturday. The high will slide 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. A stronger area of low pressure system approaches on Wednesday and moves across the area on Thursday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast on track with slight adjustments to temperatures and dew points to reflect latest observations and trends.

The upper trough continues to pass east of the area, which resulted in low pressure development well offshore. High pressure moves slowly toward the East Coast. With the building upper ridge axis, strong subsidence will continue to result in abundant sunshine today. Temperatures will be about 10 degrees below normal, only reaching the low to mid 30s. Northwest winds will gradually back toward the west and diminish through the afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. Surface high pressure builds to the south tonight. With a dry airmass in place, light winds and a clear sky, expecting ideal radiational cooling conditions. Have lowered temperatures from the previous forecast with lows now dropping into the teens and 20s. However, if winds stay elevated it is likely that the temperatures will not drop as low.

Westerly winds around the high will allow temperatures to moderate on Saturday into the mid and upper 40s.

LONG TERM /SUNDAY THROUGH THURSDAY/. The long term period starts off dominated by dry weather as high pressure remains south of the region through Monday. Expect temperatures to remain above normal as highs range from the middle 40s to lower 50s. Skies will be sunny on Sunday and most of Monday, however clouds begin to increase late in the day Monday as the next area of low pressure approaches from the south and west.

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.

There may be a brief break in the precipitation Tuesday night into Wednesday, however a much stronger low is then expected to approach and move across the area as a digging upper level trough approaches from the west. Both the upper level and surface low is now forecast to pass west of the NYC, resulting in another rain event for the local area. As the low lifts north of the region late Thursday, it will drag a cold front across the region. As the precipitation ends Thursday night, there is a chance that some of the precipitation mixes with or changes over to some snow, however no accumulations are expected at this time. Drier but colder conditions return to end the week. Expect a return to below normal temperatures on Friday high will only reach the lower and middle 20s.

AVIATION /14Z FRIDAY THROUGH TUESDAY/. High pressure remains across the terminals through the forecast period with VFR conditions.

Winds generally N-NNW around 10 kt, backing NW early aftn, then W later aftn, diminishing to 5-10 kt. Winds then back farther WSW-SW this evening.

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.
