Area Forecast Discussion National Weather Service New York NY 400 AM EST Sat Jan 16 2021

SYNOPSIS. Low pressure will deepen as it tracks along a frontal system moving across the area this morning. The low continues to strengthen as it tracks across New England this afternoon through tonight, then the Canadian Maritimes on Sunday. Thereafter, a series of cold fronts will then move across the area through the middle of next week, each followed by weak high pressure.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Low pressure is beginning to strengthen rapidly early this morning along a warm front that lies just south of Long Island. ISP just reported a 4 mb drop in pressure in one hour from 2 am to 3 am. The deepening low is expected to track north and east this morning as the main frontal system moves across the region. Deep subtropical moisture is being advected northward with widespread rain occurring across much of the region. Significant height falls aloft ahead of the associated strong upper low along with upper divergence support multiple bands of moderate to locally heavy rain moving across the area this morning. The greatest likelihood of moderate to heavy rain is east of the the NYC metro and Hudson River, where high resolution guidance continues to indicate an elevated convective band. Precipitation type will be plain rain for much of the event, although there could be a wet snowflake mixing in across the far NW interior. Have noted temperatures across the interior running a few degrees colder due to increasing northerly flow. However, with the low tracking northeast this morning, temperatures should respond and rise a bit through day break.

We received a report of hail smaller than peas in Rego Park around 2:30 am within a narrow convective band. Latest radar trends show the highest returns have weakened a bit. This band may reform however as it gets further east as the high res models have indicated.

Total rain amounts will range from one inch or less from NYC metro on west and one to two inches further east, highest across eastern Long Island and southeast Connecticut.

There could be some wind gusts 35 to 40 mph across far eastern Long Island and coastal SE CT as the low deepens.

Rain will diminish from 12-15z as the low lifts northward and the frontal system clears the region.

The upper level low will still be to our west into this afternoon. Energy flowing within the upper low will continue move overhead which will keep at least mostly cloudy skies for much of the day. There is a much lower probability of precipitation with a much drier middle and upper level atmosphere. Winds will be weakest late this morning and early afternoon as the low begins to lift north into New England. The pressure gradient steepens late in the day and westerly flow will follow suit and increase as well. Highs today will be in the middle and upper 40s.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. The upper level low will move over New England tonight, with the deepening surface low lifting towards the Canadian Maritimes. The boundary layer will be well mixed tonight with the pressure gradient in place from the departing low. The highest winds will reside close to the coast. Dry conditions are expected tonight and skies should gradually become partly cloudy, especially the second half of the night. This is due to the middle and upper level flow becoming westerly with the upper low lifting towards the Canadian Maritimes. Lows will range from the upper 20s inland to the lower and middle 30s elsewhere.

Gusty W-SW winds are expected to continue on Sunday as the region will lie within the pressure gradient left behind the departing low and high pressure building across the southern portion of the country. Gusts could reach 30-35 mph, strongest near the coast. There may also be a subsidence inversion with moisture trapped beneath it around 5 kft, which could lead to SCT to BKN stratocu in the afternoon. Highs will be in the lower to middle 40s.

The pressure gradient relaxes Sunday night and winds should weaken. Another shortwave trough approaches with mostly cloudy skies. No precipitation is expected Sunday night. Lows will range from upper 20s inland to the lower 30s most elsewhere.

LONG TERM /MONDAY THROUGH FRIDAY/. The northern branch of the polar jet will remain dominant across the NE quarter of the country through the upcoming week. This will largely result in dry, seasonably cold weather during this period.

A series of strong shortwave troughs are expected through the middle of next week, one early Monday, and another early Wednesday. While there is limited moisture available, a chance of flurries and/or a snow shower can not be ruled out on Monday and then again on Wednesday. The later shortwave will be followed by the coldest shot of air during the period with temperatures struggling to get much above freezing on Wednesday. Global models are at odds with the magnitude of this features and the associated cold air. Taking a middle road approach will still keep high in the 30s. This coupled with another day of gusty winds will keep wind chill values in the 20s.

Another northern branch shortwave will send low pressure pressure tracking north of the Great Lakes on Thursday,sending a warm front through the region. There may be a frontal wave near the near the coast, passing near the benchmark. This scenario raises the potential for some wintry weather, but many of the global models are progressive with this system and don't form a significant coastal low. For the time, chances of precipitation will remain low. A large area of high pressure then builds in for the end of the period.

AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. Low pressure moves over the area through this morning and tracks northeast during the day Saturday.

As the rain moves through, conditions will vary from MVFR to IFR with localized areas of LIFR possible.

Mainly easterly (possibly briefly northeasterly) winds of 10 to 20 kt with gusts up to 30 kt will shift to the SE and S through the morning as low pressure moves over the area. Wind speeds will decrease as the low moves overhead into the early morning and then pick up again during the afternoon as the low shifts to the northeast. Winds shift to the SW late in the TAF period. Chance of some level wind shear at KBDR and KISP, but more likely at KGON toward 10Z as a low level jet 50 to 60 kt develops.

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

Amendments are expected in varying conditions. Chance of TS at any one location is low but possible through morning.

OUTLOOK FOR 06Z SUNDAY THROUGH WEDNESDAY. Sunday. VFR. W wind gusts 25-30 kt. Gusts diminish at night. Monday. VFR. W wind gusts 15-20 kt, mainly during the day. Tuesday. VFR. Wednesday. Mainly VFR, chance of MVFR.

MARINE. Low pressure is developing over the waters early this morning. The strongest winds will be across eastern waters will the gale warning remains in effect through 6 am. Elsewhere, winds are beginning to weaken. Winds will then pick up in the afternoon with SCA winds returning to the ocean late in the day, then occurring on all waters tonight into Sunday. There is a chance at gales on Sunday on the ocean waters east of Fire Island Inlet, but for now have gone with a SCA. Winds on all waters will weaken Sunday night except east of Moriches Inlet where SCA gusts may continue. Ocean seas will remain elevated through Sunday and then slowly subside Sunday night.

A prolonged period of SCA conditions is expected on most waters from early next week as a series of cold fronts move through the waters, followed by gusty west winds.

HYDROLOGY. Storm total rainfall amounts of about 0.75 to 1.75 inches are forecast with the ongoing event. The highest amounts will occur across Long Island and southern Connecticut.Flash flooding is not anticipated due to the relatively fast motion of the storm and antecedent dry conditions. Minor urban street and poor drainage flooding however will still be possible.

No significant precipitation is expected thereafter.

TIDES/COASTAL FLOODING. A few sites will reach their minor coastal flood benchmarks in the South Shore Bays, Lower NY Harbor, and parts of southern Westchester NY and coastal Fairfield CT morning during their respective high tide cycles this morning/early afternoon. Coastal flooding does not look widespread and have gone with a statement.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory from 6 PM this evening to 6 PM EST Sunday for ANZ335-338-345. Gale Warning until 6 AM EST early this morning for ANZ330-340- 350. Small Craft Advisory until 6 PM EST Sunday for ANZ353-355.
