Area Forecast Discussion National Weather Service New York NY 1034 AM EST Sat Dec 14 2019

SYNOPSIS. Low pressure moves across the region today, then moves to the north of the area tonight into Sunday. High pressure will briefly build in for Sunday night, then move offshore Monday. A frontal system will impact the region Monday through Tuesday, followed by high pressure to close out the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Low pressure located near the Del-Mar-Va peninsula will track north and pass through with an occluded front later today. Mid levels have dried out somewhat and will remain that way through the day. Areas of drizzle or light rain can be expected across the forecast area as a result. Fog is not dense at the moment, but this could be a concern as the low passes through the region with light to calm winds and saturated low levels.

Adjusted temperatures based on latest obs, with parts of Long Island reaching 60 degrees with a warm/coastal front having moved through.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/. Early this evening the surface low and upper low will be north of the area with the negative trough axis lifting through. Upper levels will be quickly drying this evening so have lowered probabilities to chance, and then slight chance to no probabilities through early this evening. Any rain will be light. Again, may be too slow with the ending of the precipitation as heights will be rising and the atmosphere continues to dry, even at the lower levels this evening. By 05Z precipitation should be finished.

The upper flow becomes nearly zonal late tonight through Sunday, and a progressive pattern develops. The next trough will be digging into the western states Sunday, and track quickly into the area for Monday.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. With near zonal flow a progressive patter develops, and dry conditions will be short lived into early Monday. Surface high briefly builds behind the departing low to the north, and moves offshore Monday. Breezy conditions will be diminishing Sunday night as the high builds.

The next system to impact the forecast area comes Monday as the high pushes offshore and a warm front develops and approaches from the southwest while at the same time, an area of low pressure develops over the Ohio Valley. There is some uncertainty as to how quickly the cold air will be replaced as high pressure tracks off shore Monday. With the progressive low have leaned toward a slightly warmer solutions, unlike the GFS and ECMWF. This low is forecast to track along the frontal boundary, moving in the vicinity of the forecast area Tuesday. Models show that the low will not be particularly strong as it heads over our region, but there could be a period of moderate precipitation Monday night associated with the approaching warm front.

Uncertainty with model solutions Monday night onward will make precipitation type difficult to forecast at this point. However, do think thermal profiles will be cold enough at the start to support all snow at the start for most places, with a quick changeover to rain along the coast by mid Monday morning. However, QPF amounts will be light at this point, so little in the way of accumulation is expected.

Despite warming aloft, there may be enough cold air in the lower levels where there may be an extended period of wintry precipitation inland, with freezing rain among the precipitation types. Again, this is 4 to 5 days out and the forecast is likely to change over the next couple of days.

Associated cold front will move through late Monday night into Tuesday. Canadian high pressure builds in Wednesday through the end of next week, bringing below normal temperatures, but dry conditions.

AVIATION /16Z SATURDAY THROUGH WEDNESDAY/. low pressure over the Del-Mar-Va peninsula lifts north and west of the terminals this afternoon, passing to the north tonight into Sunday. The trailing cold front will move across the area this evening.

A highly complex wind forecast this morning with low to medium confidence. Generally, looking at an E-NE flow for the NYC (except JFK) and Lower Hudson Valley terminals early this morning, becoming light and variable for time before becoming southerly this afternoon. However, the eastern terminals (including JFK) veer from E/SE to S this morning.

Winds speeds increase to 10-15 kt this afternoon. Winds then significantly increase this evening behind the cold front with W-SW winds 15-20 G25-35kt.

Widespread IFR/LIFR through much of today with improvement to VFR in the evening following the cold frontal passage. OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY. Sunday. VFR. West winds around 20kt,G25-35kt. Sunday night-Monday. VFR. W wind gusts diminish to 20 kt Sunday night. Monday night-Tuesday. MVFR to IFR possible. Chance of snow for inland terminals changing to a wintry mix and then to rain. Chance of mainly rain for coastal terminals, with a period of snow or a wintry mix at the start early Monday night. Wednesday. VFR with NW gusts 25-30kt.

MARINE. Updated forecast to add dense fog on all waters through this afternoon. Low pressure center should track over portions of the waters with an extended period of relatively light winds, allowing for areas/widespread visibility of under a mile. Area web cams show most of the waters already at or near this threshold. Gale Warning remains in effect for all waters tonight and Sunday.

Low pressure over the Del-Mar-Va this morning will rapidly deepen while lifting north and west of the waters today, passing north tonight into Sunday. The trailing cold front will work across the waters this evening. SCA conditions will precede the cold front across the ocean waters today with winds becoming southerly by late.

A W-SW gale develops across the waters early this evening as the low continues to deepen to the north. Gusts up to 40 kt will be possible across all waters through the day on Sunday. Seas on the ocean will remain high, 7 to 11 ft today, and 8 to 13 ft tonight into Sunday. Seas tonight will build up to 6 ft on eastern Long Island, possibly higher on Sunday.

Winds begin to diminish late in the day Sunday, but should fall below SCA around daybreak Monday. The ocean waters may see SCA wind conditions once again Tuesday as a developing low move in the vicinity.

HYDROLOGY. Any additional rain accumulation today into this evening will be very light. The only remaining flooding concerns are for the larger stem rivers in CT where levels continue to gradually rise into this evening due to a combination of the recent rainfall and melting snow to the north.

Another significant rainfall event is possible Monday through Tuesday, with liquid equivalent QPF of 0.5 to 1.25 inches possible. There is uncertainty in this amount given uncertainty in the track of the low and frontal positions.

TIDES/COASTAL FLOODING. Minor coastal coastal flooding is expected along the south shore bays of Nassau and Queens with the morning high tide cycle, and along the coast of SW CT and S Westchester early this afternoon. This is due to a storm system that has provided a prolonged period of onshore flow along with relatively high astronomical tides due to a nearly full moon. There is also the potential for waters levels to touch moderate in the back bays of Nassau.

Elsewhere, localized minor flooding is possible along the most vulnerable locales of lower NY Harbor, eastern bays and north shore of LI, and along SE CT.

This is a one high tide cycle event.

Along the Atlantic Ocean beach front breaking surf of 8 to 13 ft (highest eastern LI) will cause significant beach flooding and erosion during the times of high tide today into tonight. Scattered areas of dune erosion and localized washovers are possible during the times of high tide Saturday morning into afternoon.

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

OKX WATCHES/WARNINGS/ADVISORIES. CT . Coastal Flood Advisory until 3 PM EST this afternoon for CTZ009-010. NY . Coastal Flood Advisory until 3 PM EST this afternoon for NYZ071.

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.
