Area Forecast Discussion National Weather Service New York NY 1128 AM EDT Fri Apr 3 2020

SYNOPSIS. Low pressure well east of Long Island will meander through tonight and then gradually out into the Atlantic on Saturday. Weak high pressure will be over the region this weekend before a weak cold front crosses the area Sunday night. High pressure then briefly returns on Monday, followed by an approaching frontal system for the middle of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Made some adjustments to forecast grids to better match observed trends. Rain will linger across much of the area into the afternoon, especially across Long Island and Southern Connecticut. The rain will be light and will become more occasional in frequency by mid to late afternoon. Temperatures were slightly lowered across parts of Long Island and coastal Connecticut and much of the interior. High temperatures will mainly be in the upper 40s to lower 50s.

Strong offshore low pressure will continues to move southwest farther out into the Atlantic through this afternoon. Rain bands will move southwestward around the large circulation during the day. The highest chance exists across Long Island and Connecticut with lower chances further west across New York City, Lower Hudson Valley, and Northeast New Jersey.

The thermal forcing wanes in the afternoon as the low weakens and drifts south away from the coast. This will lead to rain bands diminishing into the evening hours. Rainfall amounts will be light and generally around a tenth of an inch or less.

Winds will continue gusting 25-30 mph today with some isolated gusts to around 35 mph closer to the Forks of Long Island.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/. The offshore low will slowly move south and east away from the Eastern Seaboard tonight. Thermal forcing looks weak and the chance for any rain diminishes through the night. There will likely be some lingering energy wrapping around the offshore low along with moisture in the low and middle levels. This will keep mostly cloudy to overcast skies through the night. Low temperatures will be in the 40s across the region. Other than gusty winds 25-30 mph across the Forks of Long Island and Southeast Connecticut, winds should be weakening through the night.

The low continues moving offshore on Saturday but the region will likely lie on the outer periphery of the upper low and cyclonic low aloft. Moisture profiles show abundant moisture in the lower levels which indicates at least mostly cloudy skies. There should be enough breaks for partial sunshine allowing temperatures to reach the middle and upper 50s along and west of the Hudson River Corridor. Further east across Long Island and Connecticut, temperatures will generally be in the lower 50s due to influence of NE flow.

Upper and surface ridging builds over the northeast Saturday night. Models are continuing to show a vort max trapped within the ridge. However, due to the ridging aloft and at the surface, do not think any precipitation will occur. Mostly cloudy skies will be the likely result on Saturday night with temperatures falling into the upper 30s out east and lower to middle 40s elsewhere.

LONG TERM /SUNDAY THROUGH THURSDAY/. The ridge slides to the east on Sunday as heights fall a bit with an approaching shortwave. The surface high drifts offshore as a weakening cold front associated with the shortwave approaches. These systems will bring another day of mostly cloudy skies. With the front weakening as it reaches the local area, rain chances continue to look very limited. A slight chance for a few showers will be late Sunday afternoon into Sunday evening across portions of the Lower Hudson Valley and interior southern Connecticut. A few additional showers are possible overnight across eastern Connecticut and Long Island as the front pushes east of the area. High pressure then briefly builds back across the area on Monday before quickly shifting offshore by evening.

Unsettled weather then returns for the middle of the week as a disorganized low pressure system traversing the middle of the country tries to lift a warm front towards the region Tuesday into Wednesday. Models then differ in the strength and position of high pressure over eastern Canada and the role it plays in potentially slowing an approaching low over southern Canada towards the end of the long term. Given the high degree of uncertainty, maintained a slight chance to chance of showers throughout the Tuesday-Thursday period, but suspect at least some portion of this period will end up remaining dry. These features should be better resolved over the coming days.

Temperatures will remain several degrees above normal through much of the long term, with highs generally in the upper 50s to lower 60s from NYC north and west and in the mid 50s across Long Island and coastal Connecticut. Overnight lows will generally fall into the low to mid 40s in typically cooler outlying locations and remain in the mid to upper 40s in the New York City metro area.

AVIATION /16Z FRIDAY THROUGH TUESDAY/. A low pressure system will drift south over the Atlantic today.

Mainly MVFR thru the TAF period.

Gusty NW 20-30kts winds will veer to the N today. Winds relax this evening becoming more northeasterly tonight.

Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90

KJFK TAF Comments: Amendments possible for timing of MVFR.

The afternoon KJFK haze potential forecast is YELLOW . which implies slant range visibility 4-6SM outside of cloud.

KLGA TAF Comments: Amendments possible for timing of MVFR.

The afternoon KLGA haze potential forecast is YELLOW . which implies slant range visibility 4-6SM outside of cloud.

KEWR TAF Comments: Amendments possible for timing of MVFR.

The afternoon KEWR haze potential forecast is YELLOW . which implies slant range visibility 4-6SM outside of cloud.

KTEB TAF Comments: Amendments possible for timing of MVFR.

KHPN TAF Comments: No unscheduled amendments expected.

KISP TAF Comments: Amendments possible for timing of MVFR.

OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY. Saturday. MVFR cigs in the morning, then VFR. Saturday night. VFR, then MVFR cigs late. Sunday. Periods of MVFR. Monday and Tuesday. Mainly VFR.

MARINE. Gusts mainly in a 25 to 30 kt range on the waters with ocean seas of 6 to 8 ft. Gusts and ocean seas will increase going into this afternoon.

Low pressure system over the Atlantic shifts south while over the ocean waters south of Long Island winds gust could reach up to 40kts out of the north. As such a Gale Warning is in effect for the ocean east of Fire Island Inlet through tonight. Winds near NY Harbor and over Long Island Sound should remain out of the north with gusts up to 30kts through this afternoon with a small craft advisory remaining in effect for these waters through this afternoon. A Small Craft Advisory is in effect until at least early Saturday morning for the rest of the non-ocean waters.

Winds are expected to diminish Saturday, but seas over the ocean waters could remain elevated 7 to 9 feet through Saturday night. This means Small Craft Advisory conditions could remain in place over the ocean waters possibly through early Sunday morning. As the low continues to move into the central Atlantic seas subside below SCA criteria late Sunday. Winds will be lightly out of the south 5- 10kts for most of the day Sunday before shifting northwesterly 5- 10kt early Monday following a weak frontal passage.

HYDROLOGY. No hydrologic impacts are expected through next week.

TIDES/COASTAL FLOODING. A persistent gusty northerly wind, building seas/swell/and rising astronomical tide levels will likely result in a bit more widespread minor coastal flooding with the high tide mid afternoon into early evening across the back bays of Long Island and along the Great South Bay in southern Suffolk. A coastal flood advisory remains in effect here. A coastal flood statement remains for isolated minor coastal flooding across the Western Sound and along the Peconic and Gardiners Bays, specifically near Riverhead.

More widespread coastal flooding is likely Saturday morning with localized moderate flooding possible. Coastal flood advisories are likely more of the area. There may also be isolated minor coastal flooding during Saturday evenings high tide as well.

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 . Coastal Flood Advisory from 3 PM this afternoon to 7 PM EDT this evening for NYZ179. Coastal Flood Advisory from 5 PM this afternoon to 9 PM EDT this evening for NYZ080. NJ . None. MARINE . Small Craft Advisory until 6 PM EDT this evening for ANZ335- 338. Small Craft Advisory until 6 AM EDT Saturday for ANZ330-340- 345-355. Gale Warning until 6 AM EDT Saturday for ANZ350-353.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
