Area Forecast Discussion National Weather Service New York NY 950 PM EDT Mon Aug 3 2020

SYNOPSIS. A surface front will stall near the forecast area tonight. Tropical Storm Isaias will track along this boundary, directly impacting the area Tuesday afternoon and evening. A weak low pressure trough will linger in the wake of Isaias on Wednesday, then stall to the south from Thursday into Saturday as weak waves of low pressure move along it. Weak high pressure should return on Sunday and may last into Monday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/.

Showers and some strong to isolated severe thunderstorms continue to move across the area this update, through NYC, LI and the lower Hudson Valley. These should reach parts of southern CT within the next hour, as they move northeast out of the area over the next few hours. Grids updated to reflect current observational trends.

A frontal boundary will stall near the area overnight as Isaias makes its way toward the area. Most models bring in a plume of moisture well ahead of the system suggesting some sort of predecessor rain event. Per current radar trend, this precip should hold off til late evening and the overnight, with best chances across northeast New Jersey and the Lower Hudson Valley.

Otherwise, warm and humid conditions expected overnight, with lows in the upper 60s to mid 70s.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. **TROPICAL STORM WARNINGS IN EFFECT FOR THE ENTIRE FORECAST AREA**

The frontal boundary will remain stalled near the area. Meanwhile, an upper level low north of the Great Lakes region will pivot a trough through New England. This will steer Isaias over the area Tuesday afternoon.

A Flash Flood Watch continues for much of the forecast area. Please see the Hydrology section for more information regarding rainfall.

The highest wind threat with regard to Isaias should correspond to the eastern semicircle of the storm which places central and western Long Island, New York City, portions of northeast New Jersey, and portions of southern Westchester and southwest Connecticut along the axis of strongest winds. The timing for this looks to be from late in the day Tuesday into Tuesday evening. Two positive notes are that the storm is expected to accelerate to the north and northeast and it is expected to weaken as it does so. This may limit the duration of impactful winds to some extent for coastal sections. Sustained winds of around 50 mph are possible along coastal areas with gusts up to 70 mph. Generally speaking however, sustained winds of 40 to 50 are more likely across the forecast area, with gusts 55 to 70 mph.

Additionally, a strengthening low level jet will increase shear across the area. This may lead to the development of some tornadoes as Isaias moves approaches and moves through. The Storm Prediction Center has placed nearly the entire area in a slight risk for severe storms, with the primary threats being tornadoes and damaging winds (locally higher wind gusts outside of the tropical storm force winds expected to occur).

A high rip current risk remains for the ocean beaches Tuesday through Tuesday night.

LONG TERM /WEDNESDAY THROUGH MONDAY/. After Isaias passes, will still have to contend with an anomalously deep closed over southern Canada, maintaining deep layer SW flow and associated moisture/energy transfer aloft, as well as a shortwave trough diving in from the Pac NW on the back side of this low, which does not look to pass east of the area til Sunday morning. Showers/tstms may fire on Wed invof a lingering sfc trough, which then sinks to the south Wed night and stalls as weak disturbances ripple along it. Timing and placement of best rain chances appears to be Thu night and Fri night, and more so for Long Island and the NYC metro area and as compared to S CT.

Shortwave ridging aloft should finally move in for Sunday. Uncertain how long it will persist as model guidance shows the ridge passing east by Monday, followed by NW flow aloft and passing shortwave disturbances, a progression which may be a little too quick.

Temps during the period should be just a little above average, mostly in the 80s, with lower 90s possible in urban NE NJ on Wed and perhaps again by next Monday. Heat index values High temps combined with dewpoints in the 60s thru the period should yield heat index values close to actual temps.

A high rip current risk remains for the ocean beaches Tuesday through Tuesday night.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. Tropical Storm Isaias will approach from the southeast coast tonight, and will move over the Mid Atlantic and Northeast on Tuesday.

Mainly VFR through this evening outside of any showers and thunderstorms especially from NYC terminals and west. Any storms will be capable of producing strong wind gusts and heavy downpours which could result in lower visibility. Showers become more likely late tonight into early Tuesday morning with MVFR to IFR conditions developing.

Winds will gradually turn SE/E overnight into tomorrow morning. SE winds increase in speed after 12z tomorrow morning, with gusts in the afternoon 40-60 kt. The strongest winds will across the coastal terminals. As Isaias moves away to the northeast in the late afternoon, a quick shift to SW winds is likely.

OUTLOOK FOR 18Z TUESDAY THROUGH SATURDAY. Tuesday afternoon-Tuesday night. Showers and a chance of thunderstorms with MVFR to IFR conditions. Impacts from Tropical Storm Isaias likely into the evening. Conditions improving late Tuesday night. Wednesday. VFR with any lingering showers ending. Thursday and Friday. VFR. Saturday. MVFR possible in SHRA.

MARINE. Conditions remain below SCA criteria through tonight. Conditions deteriorate Tuesday morning, with increasing tropical storm conditions from late Tuesday afternoon into Tuesday evening across all of the coastal waters based on the latest forecast track of Isaias. A Tropical Storm Warning is in effect for all forecast waters. Winds of 45-50 kt will be possible with gusts up to 60 kt. Isolated gusts of just over 60 kts are possible. Conditions will then improve quickly Tuesday night from west to east. Wave heights will briefly build to around or just over 15 ft out on the ocean waters late Tuesday afternoon into the early evening, then subside fairly quickly into Tuesday night. Waves of 6 to 10 ft are possible on the sound waters and 3 to 5 ft across the back bays and Peconic and Gardiner's Bays.

Small craft conditions will then ensue on the ocean during the day on Wednesday due to elevated seas. As early as Wednesday night even the ocean waters should settle down to below SCA conditions for Wednesday night into Thursday with some 3-4 ft seas lingering out on the ocean.

HYDROLOGY. There is the potential for more widespread heavy rainfall, especially Tuesday into at least into the first half of Tuesday night as Isaias approaches the region. Additionally, the track of Isaias will need to be monitored to narrow down potential impacts for minor to moderate river flooding. Confidence in any moderate river flooding remains low due to rainfall forecast uncertainty.

A flash flood watch remains for Tuesday through Tuesday night for NYC, Northeast NJ, and the Lower Hudson Valley where guidance is lower with rain amounts for flash flood criteria. This is also closer to the heavier rain axis forecast.

TIDES/COASTAL FLOODING. Coastal flood warnings are now in effect for south facing shorelines of Long Island Sound, and western Long Island, and in/around NY Harbor, with advisories for the remaining waters.

A strong SE flow ahead of Tropical Storm Isaias could produce surge of 2 1/2 to 3 1/2 ft across the watch area and 1 to 2 ft elsewhere. This would result in widespread inundation of 1 to 2 ft with localized values up to 3 ft in the watch area. There is still uncertainty in the guidance at this time with preference toward the higher end of the PETSS and NYHOPS guidance.

This is appears to be a one-cycle event, as winds shift W on the back side of the storm late Tuesday evening.

EQUIPMENT. NYC NOAA Weather Radio Station KWO-35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.
