Area Forecast Discussion National Weather Service New York NY 805 PM EDT Mon Jun 1 2020

SYNOPSIS. High pressure settles along the Southeast coast through Tuesday morning. A warm front approaches late Tuesday and moves across Tuesday night. A surface trough will then linger into Wednesday. A cold front will move through late Wednesday night into early Thursday. Another cold front will move through Saturday, followed by high pressure for the remainder of the weekend into the beginning of next week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Radar shows some sprinkles moving across the forks of Long Island and SE CT early this evening in association with a mid level vorticity max moving across. Otherwise, the region will be sandwiched between an upper trough trough offshore and a building ridge across the center of the CONUS. Stratocu may dissipate this evening some with loss of daytime heating, then weak warm advection and increasing middle level moisture will lead to mostly cloudy skies overnight.

Lows will range from the upper 40s inland, to the lower and mid 50s elsewhere.

There is a moderate risk for the development of rip currents at the ocean beaches into this evening due to a south to southeast long period swell.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. Warm advection continues in the low and middle levels on Tuesday. The main warm front will be setting up well to our west during the day. Model forecast soundings indicate dry air in the lowest 5 to 10 kft that will prevent anything more than isolated sprinkles in the morning. In fact, the daytime hours may end up completely dry as forcing is very weak. The dry air will also be a negating factor to any precipitation. Middle and upper level moisture increases in the afternoon ahead of a shortwave that will begin diving southeast out of Canada. This feature will be responsible for driving the warm front towards the area Tuesday night. High temperatures on Tuesday will continue a few degrees below normal in the lower 70s.

There are still some discrepancies on coverage of showers Tuesday night as the warm front nears. Models agree that a wave of low pressure will traverse across northern New England towards early Wednesday which should help move the warm front into the area. It is possible the warm front does not fully move across until later Wednesday morning. Probability of showers increases Tuesday night with the warm front and positive vorticity advection ahead of the 500 mb shortwave diving within the NW flow. Lows will be in the 50s.

There is a moderate risk for the development of rip currents at the ocean beaches Tuesday due to a continuing southeast long period swell.

LONG TERM /WEDNESDAY THROUGH MONDAY/. A weak upper level trough will move across the Northeast on Wednesday as a cold front approaches from the west. Ahead of the cold front, a pre-frontal surface trough will affect the forecast area during the day. This will provide some focus for lift for some showers. However, better forcing will occur later in the day, as stronger lift and more in the way of instability is expected. The air mass will also become more humid as dew points rise into the 60s. Some strong storms are possible, particularly north and west of New York City, with lifted indices of 0 to -6 noted across northeast New Jersey and the Lower Hudson Valley during the afternoon. Surface CAPE values are not too impressive, but would support at least some thunderstorms for those areas, with values around 1000 J/kg. A few hundreds J/kg of elevated CAPE noted as well in model soundings. SPC has placed a portion of the area in a marginal risk for severe thunderstorms on Wednesday.

The cold front pushes off shore late Wednesday night into Thursday morning, with dry conditions expected through the day Thursday.

Another frontal system approaches from the west Thursday night, with a warm front lifting north of the region Thursday night. Unsettled conditions are then expected from Thursday night through Saturday as the cold front moves through. The area dries out late Saturday night, with Canadian high pressure returning through the beginning of next week. A noticeably cooler, less humid air mass will move in for Sunday into Monday.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. VFR as high pressure passes to the south. NW-N winds 5 to around 10 kt early from NYC metros north/west will shift W and diminish overnight. Coastal sea breezes expected late morning and afternoon on Tue.

OUTLOOK FOR 18Z TUESDAY THROUGH SATURDAY. Tuesday night. VFR to start, then chance of showers with MVFR cigs likely. Wednesday. MVFR conds possible in showers. Chance of afternoon/evening thunderstorms. Thursday. VFR. Friday and Saturday. MVFR possible in showers.

MARINE. High pressure settles to the south of the waters tonight into Tuesday. A warm front approaches late Tuesday and begins to move across the waters Tuesday night. SCA conditions are forecast on the waters through Tuesday night. Winds could approach 20 kt on Tuesday, but ocean seas will be around 3 ft through this period.

Lack of a strong pressure gradient will keep winds below 25 kt from Wednesday onward across all coastal waters.

Ahead of a cold front late Wednesday into Wednesday night seas on the eastern ocean waters will approach marginal small craft criteria. Seas will remain 4 to 5 feet for the eastern 2/3 of the ocean waters through the first half of Thursday night, before subsiding slightly into Friday morning. Otherwise, the remainder of the forecast waters remain below SCA levels Wednesday night through Friday.

Waves build to 4 to 5 ft for the eastern 2/3 of the ocean waters once again Friday night as another frontal system approaches from the west, setting up a southerly flow over the ocean waters.

HYDROLOGY. No hydrologic impacts expected through next Tuesday.

TIDES/COASTAL FLOODING. A southerly swell and rising astronomical tides could aid in some coastal locations approaching minor coastal flood benchmarks for the Wednesday evening high tide cycle.

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

KOKX WSR-88D radar will be down for approximately two weeks for the pedestal refurbishment.

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.
