Area Forecast Discussion National Weather Service New York NY 608 PM EDT Sat Apr 4 2020

SYNOPSIS. Weak high pressure briefly builds into the region tonight, moving off shore Sunday. A weak cold front moves through Sunday night. High pressure returns Monday and Tuesday. A series of frontal systems may impact the region Wednesday through Friday. High pressure builds back in for the weekend.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Just minor updates to temperatures/dewpoints and sky coverage to better reflect current conditions and trends. Otherwise, a very weak gradient flow will be across the region through tonight. There is a weak surface trough expected to remain across the lower Hudson Valley into northern New Jersey. Weak warm advection and lift could produce light showers/sprinkles. The NAM and HRRR are indicating the chance of precipitation. At this time will have a mention of sprinkles.

SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/. The surface high remains Sunday, moving east late day and into Sunday night. Aloft weak ridging remains across the area. A weak shortwave and cold frontal boundary move through the ridge Sunday afternoon and Sunday night. There is little forcing ahead of and with the front, along with some low level moisture. Will maintain the slight chance probabilities Sunday afternoon and Sunday night.

LONG TERM /MONDAY THROUGH SATURDAY/. High pressure builds briefly across the region Monday resulting in sunny skies and temperatures in the 60s. Thereafter several weak systems are forecast to track across the region right through the end of the week, bringing scattered showers at times across the area. There is still some uncertainty with the exact timing and track of each system.

High pressure will then gradually build in late in the week and into the start of the following weekend with diminishing winds and dry weather expected. Temperatures on average will remain several degrees above normal through much of the long term, with temperatures trending cooler during the second half of the period.

AVIATION /22Z SATURDAY THROUGH THURSDAY/. A weak flow will develop across the area this afternoon with weak high pressure just off to the east and a trough across the Hudson Valley.

VFR through this early this evening with MVFR conditions returning during the overnight. Amendments are likely due to timing. Chance of brief IFR ceilings toward daybreak. Gradual improvement to VFR by afternoon. A few sprinkles are also possible overnight.

NE winds will gusts up to 20 kt through about 20Z at KGON. Elsewhere, winds will diminish and become S/SE at less than 10 kt. Light southerly winds continue overnight into Sunday.

OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY. Sunday. Mainly VFR. Slight chance of showers afternoon and evening. Monday-Tuesday. Mainly VFR. Slight chance of rain on Tuesday. Wednesday. MVFR or lower and rain possible. Thursday. Chance of MVFR in showers.

MARINE. With low pressure continuing to move into the Atlantic tonight northeast winds were still gusting to near SCA levels east of Moriches Inlet. The gusts are expected to fall below advisory levels early this evening.

Weak high pressure builds into the waters tonight and early Sunday before moving east Sunday afternoon and Sunday night. Winds will remain below SCA levels across the forecast waters through Sunday night. However, ocean seas remain elevated with an easterly swell, and will remain elevated into late Sunday evening as a cold front approaches. The ocean SCA was extended to 06Z Monday.

Below SCA conditions across the area water expected through the end of the week.

HYDROLOGY. No hydrologic impacts are expected through the period.

TIDES/COASTAL FLOODING. Easterly swells will continue to keep water levels high enough across the south shore back bays of LI for localized minor coastal flooding around the time of high tide this evening. This will also be possible again Sunday morning. A coastal flood statement has been issued for this evening.

Breaking waves of 4 to 7 ft will be slow to subside through Sunday morning. Scattered areas of beach erosion and localized washovers are possible during the times of high tide along the Atlantic oceanfront.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory until 2 AM EDT Monday for ANZ350-353-355.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
