Synopsis for the long island waters and new york harbor.. A cold front will stall within the area and weaken today into tonight. Impacts from tropical storm isaias are expected Tuesday into Tuesday night. As isaias rides quickly northeast of the area on Wednesday a cold front will push off to the east, followed by building high pressure later next week. Please refer to national hurricane center forecasts for further details on isaias.

Area Forecast Discussion National Weather Service New York NY 1253 PM EDT Mon Aug 3 2020
SYNOPSIS. Upper level trough axis over the Great Lakes region moves little through mid week. A surface front pushes just east of the Long Island then stalls over the area today. The southwest flow steers Isaias north along the East Coast through the near term.
Impacts from Tropical Storm Isaias are possible Tuesday and Tuesday night. As Isaias rides quickly northeast of the area on Wednesday a cold front will push off to the east, followed by building high pressure later next week and into the start of next weekend. A weak disturbance may pass by the north for late next weekend.
NEAR TERM /THROUGH TONIGHT/. With higher confidence of tropical storm force winds to impact inland areas that previously had watches in effect, upgraded those areas to warnings. The entire forecast area is now under a Tropical Storm Warning.
As the surface low pressure system exits the northeast drier air briefly settles in behind the slow moving trailing surface front. Dew points fall into the mid 60s during the day owing to a combination of the change of airmass and ample diurnal mixing. Clearer skies will help ambient temperatures reach the upper 80s and low 90s through out the area by the afternoon.
Late Monday afternoon into the evening sees a potential predecessor rainfall event. The deep trough over the Great Lakes region pulls tropical moisture north from Isaias with additional lift coming from a shortwave trough embedded within the flow regime. Likely rainfall will be akin to warm frontal showers with amounts ranging between 0.15 to 0.25 inches overnight.
SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/. Isaias will likely impact the area starting Tuesday. There is a tropical storm warning in effect for the entire forecast area.
The upper level trough will steer Isaias north along the east coast early morning Tuesday. The system is expected to reach the southern portions of the forecast area Tuesday into Tuesday evening.
The timing of the heaviest rainfall is late Tuesday morning into Tuesday evening across the entire CWA. The axis of heaviest rainfall will likely be focused on the eastern counties. Particularly for Northeast New Jersey, the Lower Hudson Valley, and the NYC metro. Issues with runoff related flash flooding will be likely throughout urban environments. The current thinking is a wide swath for the potential of a 2 to 4 inch rainfall across the area with locally higher amounts of around 5 inches possible, with the eventually storm track ultimately deciding where the axis of heaviest rainfall sets up.
The highest wind threat with regard to Isaias should correspond to the eastern semicircle of the storm which places central and eastern Long Island, along with eastern CT along the axis of strongest winds. The timing for this looks to be during late in the day on Tuesday and into Tuesday evening. One positive note is the storm is expected to accelerate to the north and northeast into Tuesday and Tuesday night. This may limit the duration of impactful winds to some extent for coastal sections. The preliminary guidance is suggesting the strongest winds may get up to 45 mph sustained along the immediate coast near the center of circulation, with perhaps gusts to around 60 mph or thereabouts across southern coastal sections of New York City, Long Island, and potentially coastal Connecticut into Tuesday evening.
LONG TERM /WEDNESDAY THROUGH SUNDAY/. By Wednesday morning the center of circulation will be pushing into New England and the winds across eastern sections should shut off quickly.
As a cold front pushes east of the area on Wednesday a broad area of high pressure will begin to gradually settle in from the west. The high will settle over the region by Friday into Saturday. During this time frame the weather is expected to remain predominantly dry, with mainly a slight chance of a few late showers / storms. The humidity will become noticeably lower into Thursday as the drier air mass takes hold. The humidity will then begin to creep up closer to Saturday as heights build slightly and the drier air mass undergoes some modification.
A high rip current risk remains for the ocean beaches Tuesday through Tuesday night.
AVIATION /18Z MONDAY THROUGH SATURDAY/. A weak cold front will remain near the region into this evening. Tropical Storm Isaias begins to approach from the southeast coast tonight and will move over the Middle Atlantic and Northeast on Tuesday.
W-SW winds around 10 kt to start will become SW 10-13 kt into the afternoon. A few gusts 15- 20 kt cannot be ruled out in the afternoon. Wind speeds will weaken this evening as the direction gradually becomes SE overnight.
VFR expected through this evening. There is a chance for showers and thunderstorms early evening, but coverage and timing too low/uncertain to include in the TAFs. Showers become likely late tonight into early Tuesday morning with MVFR to IFR conditions developing.

OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY. Tuesday through Tuesday Night. Showers and a chance of thunderstorms with MVFR to IFR conditions. Impacts from Tropical Storm Isaias likely late morning into the evening. Conditions improving Tuesday night. Wednesday. VFR with any lingering showers ending. Thursday and Friday. VFR.
MARINE. Conditions on the ocean remain below SCA conditions for most of Monday with winds 13-15kts and gusts 17-20kts. Conditions worsen Tuesday morning with south winds increasing to 20kts and waves 4-5 ft.
Tropical storm conditions will become increasingly likely 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 45-50kts will be possible with gusts up to 64kts. Conditions will then improve quickly Wednesday morning from west to east. Wave heights will briefly build to around of just over 15 ft out on the ocean waters late Tuesday afternoon, then range from 10-15 ft Tuesday evening, then subside fairly quickly into Wednesday morning.
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. A coastal flood watch has been issued for Lower NY Harbor and the south shore back bays of western Long Island for the evening high tide cycle on Thursday.
A strong SE flow ahead Tropical Cyclone Isaias will potentially result in a 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. Should these values continue to increase as the event nears watches may need to be expanded and eventually elevated to a warning.
This is appears to be once cycle event with westerly flow developing on the backside of the system 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.
