Area Forecast Discussion National Weather Service New York NY 1236 AM EST Fri Dec 6 2019

SYNOPSIS. A surface ridge axis approaches overnight and moves quickly through the area in the morning. A fast moving low will then pass to the north late in the afternoon into the early evening, sending a cold front across the area. High pressure builds in through Saturday, then offshore on Sunday. A complex frontal system will impact the area early next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Wind gusts still hanging across some spots with gusts up to 25 mph. However, surface ridge axis approaching from the west will allow for wind to diminish to less than 10 mph through daybreak.

Scattered to broken stratocumulus will continue to diminish in coverage. High clouds may increase late, so a partly cloudy sky condition remains through the night.

Lows tonight will fall into the 20s and lower 30s.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/. The ridge of high pressure slides eastward early Friday morning, giving way to a weak low pressure system and associated cold front. This low will approach from the Great Lakes and pass north of the region during the afternoon.

This will bring chances of precipitation mainly during the afternoon and evening hours with the higher chances generally over northern and eastern areas. The precipitation, may start as a brief period of light snow, but rain should be the primary p-type. Any potential snow accumulations would be very light if any at all. The low and cold front move east of the area after 00z on Saturday, with drier and colder air working back into the region. Highs on Friday will climb into the upper 30s and 40s with Friday nights lows falling into the 20s. Sided with some of the colder guidance for Friday afternoon for afternoon highs.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Cold and dry weekend expected as a surface high pressure system builds into New York State beginning Saturday. This dense 1030mb airmass advects in quite cold temperatures. Daily highs will struggle to reach the upper 30s Saturday afternoon nearly 10 degrees below normal. Min temps overnight fall into the mid 20s across Long Island and into the upper teens for the Lower Hudson Valley. Temperatures do improve Sunday as the high shifts off the east coast by the afternoon allow south winds to bring in additional heat and moisture for the day. Temperatures rise to the mid 40s along with dew points in the low 40s. We'll have to keep an eye on overnight fog development Sunday night into Monday as Min temps will be hovering around those dew points.

Early next week, a shortwave trough dives south through the Dakotas deepening a low over the Great Lakes Region. As this low shifts east over the Ohio River Valley during the day, model guidance is hinting at south winds bringing scattered showers for the forecast area Monday morning becoming more widespread into the afternoon ahead of the system. There's some discrepancy in whether these are warm advection showers or typical offshore storms. Regardless, precipitable water values increase to around 1.00-1.15 inches well above the daily sounding climatology. Rain within this moist airmass could cause widespread nuisance flooding with isolated areas seeing 1-2 inches of rain through Monday evening. On Tuesday aided by a 140+ kt jet streak over the Lower Mississippi Valley the aforementioned low continues northeast into Quebec Province. Locally rain continues to fall as south winds shift southwest. Could see an additional 1-2 inches of rain Tuesday with increased rain rates as global models indicate a slow moving line of showers works its way west to east ahead of the cold front. Mild temperatures in the mid 50s will be possible both Monday and Tuesday despite the rain. West winds associated with the cold front push through midnight into Wednesday morning making drier and cooler conditions are likely through mid week.

AVIATION /06Z FRIDAY THROUGH TUESDAY/. High pressure settles south early this morning. A cold front passes this afternoon and evening.

WNW winds will continue to diminish early this morning. Any gusts initially will be occasional. Winds should be below 10 kt after 09z. Winds back to the SW in the morning and then increase through the day with gusts 20-25 kt possible in the afternoon. Winds shift to the NW with the cold front passage in the evening, and gusts will likely continue.

VFR through the TAF period. There is a chance for a mix of light snow and light rain across the interior Lower Hudson Valley terminals and across most of Connecticut terminals, mainly late Friday morning into Friday afternoon. For now have gone with a PROB30 at KSWF and KGON to account for this potential.

OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY. Friday night. VFR with NW winds G20kt possible. Saturday-Sunday. VFR. Sunday night and Monday. Rain showers likely with MVFR or lower conditions. Tuesday. MVFR or IFR in rain, with conditions improving at night.

MARINE. SCA continues for the ocean, eastern sound,and Peconic and Gardiners Bays. Overall winds will gradually weaken through the night. A relatively tranquil period follows for Friday morning, but SCA conds could enter the ocean waters by day's end and become more likely at night. There could even be some gusts to 25 kt over the eastern Sound and Bays late Friday night.

Winds will remain below small craft levels over the weekend. South winds increase to 23-28 mph nearing SCA conditions Monday morning through the afternoon. Seas increase 6-9 feet by the afternoon associated with a complex system over the marine zones beginning early next week. As the system leaves the area early Wednesday winds shift westerly but maintain strength through mid week.

HYDROLOGY. No significant liquid equivalent is forecast through Sunday. A significant long duration rainfall event is possible beginning Monday through Tuesday night.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.

The KOKX WSR-88D radar will be out of service until approximately 12/7 due to the refurbishment of the transmitter. This work is part of the NEXRAD Service Life Extension Program.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory until 6 AM EST early this morning for ANZ330-340-350-353-355.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
