Area Forecast Discussion National Weather Service New York NY 109 AM EST Tue Dec 1 2020

SYNOPSIS. Low pressure over upstate New York will meander into southern Canada Tuesday, then lift farther north into southeastern Canada midweek, with a series of low pressure troughs pivoting through the region. High pressure builds across the Mid Atlantic on Thursday. The next frontal system will swing through the region Friday into Friday night, followed by the potential for a wave of low pressure near the coast or remaining offshore for the second half of the weekend.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Made minor adjustments to hourly temperatures through the remainder of the overnight. Also reduced PoPs as all of the rain has pushed well east of the local area. Can't completely rule out a pop up shower, but the region will be primarily dry.

Overnight lows will range from the mid 40s well north and west of NYC to the low to mid 50s across far eastern Connecticut and Long Island. These temperatures are around 15 degrees above normal for the last day of November.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/. Large and deep closed low will slowly drift north through the eastern Great Lakes into Southern Ontario/Quebec through this time period, with an unsettled cyclonic flow over the region.

An associated cold front moves through the region Tuesday morning bringing a chance of showers, and a caa gusty WSW flow (30-35 mph). Considerable cloudiness and iso-sct diurnal instability showers will persist through the day as a secondary trough rotates through.

Temperatures on Tuesday will remain nearly steady during the day, after morning highs in the upper 40s/lower 50s.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. A fairly stable long wave pattern is expected throughout the extended period. To begin the period a persistent westerly flow will be in control as occluded low pressure continues to drift north across Eastern Canada. A fair amount of cloud cover is expected along with breezy and seasonably cool temperatures Wednesday into Thursday. Late Wednesday night and into Thursday high pressure off to our south and west will build and take more control of our weather with more in the way of sunshine anticipated for Thursday.

A cold front / surface trough is expected to approach from the west on Friday. There is some model disagreement as to how much moisture can move up from the south and southwest as a positively tilted trough attempts to set up for very late in the week and into the start of the weekend. For now chose to go with slight chance to low end chance POPs for late Friday into Friday night as the upper level energy and forcing mechanisms will likely get sheared and shunted to the east as the upper level pattern get somewhat out of phase. The trough however will attempt to reload and deepen later in the weekend. The exact timing of this is in doubt with the various global model camps differing a good deal with their surface progs, and thus sensible weather timing differences. For the time being, hedged with some surface ridging attempting to briefly build for much of Saturday, followed by chance POPs for Saturday night into Sunday as some coastal development attempts to get going. The ECMWF is the slowest with regard to coastal development as it keeps a confluence zone to our north close by for early in the weekend, followed by low pressure development near and offshore for late Sunday into early Monday. Confidence remains well below average for later in the extended period, thus chose to go more with a blended ensemble approach as per WPC. Temperatures should average fairly close to normal overall, with temperatures potentially turning somewhat colder into the first half of next week.

AVIATION /06Z TUESDAY THROUGH SATURDAY/. Low pressure moving through upstate New York will track slowly northward into Canada early Tuesday, then meander during Tuesday and Tuesday evening.

Mainly VFR, with MVFR at times through 09, for ceilings, and isolated fog. Widespread VFR is expected by Tuesday morning. Scattered to isolated showers will be possible during the day, however, no impact to ceiling or visibility is expected.

Southerly winds 10-15kt along the coast, and less than 10kt inland. Winds increase during the day with gusts developing in the morning, and gusts peaking 25 to 30kt during the afternoon. Wind and gusts diminish during Tuesday evening, with gusts ending outside of the New York City terminals.

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

Amendments overnight with improving conditions. No unscheduled amendments expected Tuesday. Gusts may be a few knots higher in the afternoon, especially along the coast.

OUTLOOK FOR 06Z WEDNESDAY THROUGH SATURDAY. Late Tuesday night. VFR. SW winds G20-25kt at the New York City terminals. Wednesday. VFR. W/SW winds G20kt. Thursday. VFR. Friday and Saturday. Mainly VFR. MVFR possible with any scattered showers.

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

MARINE. Allowed the Gale Warning to expire as winds have fallen below 35 kt on all waters. Issued a Small Craft Advisory in its place for the eastern Long Island Sound and ocean, where seas will remain above 5 ft through the overnight. Marginal SCA winds are also possible overnight on the ocean, and gusts 25-35 kt will return after daybreak as gusty southwest winds develop in the wake of a cold frontal passage.

Elsewhere, a Small Craft Advisory goes into effect this morning as winds once again increase to 25 kt. Winds will gradually diminish on the nearshore waters overnight, falling below 25 kt by Wednesday morning.

SCA conditions will likely persist on the eastern near shore waters and the ocean into Wednesday and Wednesday night, with more marginal SCA conditions likely for the western most near shore waters. Late Wednesday night into Thursday as low pressure gradually pulls further north and high pressure attempts to nose in from the southwest the winds will gradually decrease with sub SCA conditions likely returning to the waters from west to east. For Thursday night through Friday marginal SCA conditions may linger at times for the eastern ocean waters on a west to southwest flow regime and 4 to 5 ft seas. Otherwise, Sub-SCA conditions should return for the remaining waters for the end of the week.

HYDROLOGY. No hydrologic impacts are forecast at this time from late tonight through the weekend.

TIDES/COASTAL FLOODING. There may still be some localized minor coastal flooding with the Tuesday morning high tide for the Queens and Nassau south shore back bays. Chose to go with a statement here as the tide will be a touch higher for Tuesday morning, and also due to an over performance of the high tide from earlier this evening in these places. Will also have to watch eastern great South Bay with WSW flow.

After Tuesday morning high tide, no coastal flooding is anticipated through the middle of the week.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory from 10 AM this morning to 6 AM EST Wednesday for ANZ335-338-340-345. Small Craft Advisory until 6 AM EST Wednesday for ANZ330-350- 353-355.
