Area Forecast Discussion National Weather Service New York NY 145 AM EDT Tue Aug 4 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 THIS MORNING/. 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. Radar trends indicate rain should begin overspreading northeast New Jersey and the Lower Hudson Valley early this morning.

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

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/. **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 NIGHT 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 /06Z TUESDAY THROUGH SATURDAY/. ***High Impact Aviation Weather Expected Today***

Isaias continues moving quickly towards the NE from the Carolinas and Middle Atlantic today.

Mainly VFR early this morning will become MVFR as showers develop from south to north. E-SE winds will also increase through the morning as Isaias approaches. Showers will continue through the much of the day, with the greatest coverage from NYC metro terminals to the Lower Hudson Valley Terminals. There could be isolated thunderstorms, but have not included in TAF due to low confidence in coverage and duration.

The strongest winds are expected this afternoon with sustained winds 30-40 kt with gusts 45-60 kt. The strongest winds will likely occur across the coastal terminals. Low level wind shear is likely as well as winds at 2 kft could range between 60-70 kt 19-22z.

As Isaias moves away to the northeast in the late afternoon, a quick shift to SW winds is likely and conditions become VFR. Winds will also gradually diminish through the evening.

OUTLOOK FOR 06Z WEDNESDAY THROUGH SATURDAY. Tuesday night. Conditions improving as Isaias lifts to the north east. Wednesday. VFR with any lingering showers ending. Thursday-Saturday. Mainly VFR.Afternoon SHRA possible.

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.
