Area Forecast Discussion National Weather Service New York NY 136 PM EDT Sat Sep 19 2020

SYNOPSIS. High pressure will remain anchored across the northeast through Sunday. The high will then gradually weaken and shift south and west of the area by mid week, while tropical cyclone Teddy approaches the Canadian Maritimes. A frontal system moves into the area late in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast on track, made only minor adjustments to temperature and dew points to capture current observations and trends.

Strong surface high pressure will remain across the northeast through today with a cool and dry airmass in place. Temperatures will remain as much as 10 degrees below seasonal normals. And with weak cold advection and a moderate pressure gradient force across the area, winds will remain gusty.

There is a high risk of rip currents at Atlantic Ocean beaches today due to rough ocean seas of 5-6 ft, large directional difference between the wind (NE) and a gradually building long period swell (SE).

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/. The strong surface high across the northeast will remain in place, as an upper ridge builds eastward from the upper plains states. With a weakening pressure gradient force and weakening cold advection gusty winds will be diminishing Saturday night and through the day Sunday. With light winds and clear skies conditions will become ideal for radiational cooling. Temperatures across the interior are expected to fall into the mid and upper 30s, and with dew points in the lower to mid 30s, patchy to areas of frost will be more widespread than Friday night, and a frost advisory may be needed for Saturday night.

Temperatures tonight and Sunday will remain as much as 10 degrees below normal.

There will be a continued high risk of rip currents at Atlantic Ocean beaches on Sunday as the seas continue to build as well as the long period swell.

LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/. Strong high pressure over the northeast at the onset of the period will begin to weaken and shift south and west of the area Tuesday into Wednesday. Global models are in very good agreement with sending an upper trough across the Northeast Sunday and offshore Sunday night. The latter of which will interact with Hurricane Teddy, east of New England, steering the system toward the Canadian Maritimes Tuesday into Wednesday. The forecast area would be far enough removed from the system to not see any direct impacts other than gusty NW winds and swells. Refer to the latest official forecasts from The National Hurricane Center.

A late week frontal system will then bring a low chance of showers to the area Thursday night into Friday.

Before then though, the area will reside in NE flow Sunday through Monday which at times will gusts up to 20 mph, especially near the coast. Winds then back to the NW on Tuesday and even more westerly by mid week.

Under mainly clear skies, temperatures will be close to 10 degrees below normal for the last couple of days of summer before rebounding back to near or above normal by mid week.

High surf, beach erosion, and beach flooding are likely Sunday into Tuesday. Refer to Tides/Coastal Flooding section below for additional details. There will be a high rip current risk through at least Tuesday.

AVIATION /17Z SATURDAY THROUGH THURSDAY/.

High pressure will build in from the northwest through the TAF period.

VFR. A NE-N flow will continue through the TAF period.

Sustained winds between 10-15 kt with gusts to 20kt through mid afternoon. Gusts then diminish at all terminals by 00z. Winds will remain from the north between 6-10 kt overnight. Gusts are expected to re-develop Sunday morning, around 12z. Like today, gusts may be occasional at times.

. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

Gusts could be only occasional at times today. Some uncertainty for the end time of wind gusts later today.

OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY. Sunday afternoon and Monday. VFR. NE winds gusts around 20kt, mainly during the daytime, and highest along the coast. Tuesday. VFR. NW winds gusts 20-25 kt. Wednesday and Thursday. VFR.

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

MARINE.

With a persistent north to northeast flow, and swells from Teddy, ocean seas will remain elevated through at least Monday, and a SCA on the ocean waters remains through Monday afternoon. The SCA may need to be extended later as ocean seas may remain elevated into Tuesday.

FIRE WEATHER. Northerly wind gusts of 20 to 25 mph early this afternoon, combined with low relative humidity values of 25 to 30 percent will allow for the enhanced spread of any fire. A special weather statement remains in effect through early this evening.

Sunday winds will be north to northeast with gusts up to 20 mph, and afternoon relative humidity 27 percent to 32 percent.

HYDROLOGY. No hydrological concerns are anticipated through the entire forecast period.

TIDES/COASTAL FLOODING. Widespread dune erosion and scattered overwashes expected for the ocean beachfront Sunday into Monday . Numerous tidal cycles of minor coastal flooding expected for the south shore bays of W LI, Lower NY/NJ harbor, SW CT, and S Westchester through Sunday, and possibly through early next week.

Astronomical tides continue to run high associated with a recent new moon, with a persistent NNE flow through Monday and tidal piling allowing for 1/2 to 1 1/2 ft of surge.

Primary concern is the combination of elevated water levels and incoming energetic swells from Teddy building to our shores tonight into Monday. This is expected to develop high surf of 8-12 ft Sunday into Monday, which combined with elevated water levels during the times of high tide will likely result in significant and widespread erosion and damage to dune structures. In addition, scattered overwashes are likely, resulting in minor to moderate flooding of roadways and vulnerable structures behind protective dunes. This is depicted in the NOAA/USGS Coastal Change Forecast Viewer, which is showing potential for an erosion and overwash event close to what was seen the October 10th 2019 Nor'easter and possibly during Hurricane Jose swell event.

In terms of the coastal flood threat, the widespread minor coastal flooding can be expected across the South Shore Bays of Nassau and Queens as well as lower NY/NJ Harbor and SW CT as well as S Westchester. Isolated minor coastal flooding is expected for shorelines of Northern Long Island this afternoon.

A similar threat likely for Sunday morning high tides. Brief and localized minor flooding likely for the night time high tides tonight and Sun Night.

A similar coastal flood threat is likely to at least continue into the Monday and Tuesday daytime high tidal cycles as Hurricane Teddy makes it closest approach, with potential for moderate coastal flood impacts along vulnerable Great South Bay and areas as energetic swells from Teddy restrict tidal drainage.
