Area Forecast Discussion National Weather Service New York NY 132 PM EST Fri Nov 22 2019

SYNOPSIS. A cold front will move through the area this afternoon. High pressure will then briefly return for Saturday. Next low pressure system brings moderate rain Saturday evening and all day Sunday. Weak high pressure then builds in for Monday through the middle of next week. A cold front will move through late Wednesday into Wednesday night.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Probabilities have been adjusted based on the 12Z HREF. Otherwise, no major changes were made to the forecast. Shortwave trough extending south through the Ohio River Valley pivots across New York State today. This trough brings with it significant PVA and dynamically driven lift through the region which will act as the main lifting mechanism for precipitation this afternoon. Temperatures in the afternoon will be relatively mild reaching the mid 50s before the expected rain. Precipitable water values prior to the cold front are around 0.60-0.90 inches which is slightly more than the 75% moving average according to the SPC sounding climatology. Meaning there is a fair amount of ambient moisture to generate light to moderate rainfall. Rainfall totals range from 0.10-0.25 inches with the larger amounts expected east of the NYC Metro.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. Following the cold front, conditions will be breezy with dewpoints dropping into the low 20s with overnight low temperatures falling into the low 30s and upper 20s. The high pressure system and associated cold airmass shifts overhead as a mid- level ridge builds from the west. A chilly Saturday is still expected despite the clear skies with temperatures only reaching the mid 40s by the afternoon.

Towards the evening and overnight hours on Saturday a shortwave trough and deepening low pressure system near the Appalachian Mountains will have to be monitored for the next batch of impactful weather. Initially, as the system nears the Lower Hudson Valley, precipitation falling through the residual cold airmass may be able to refreeze prior to reaching the surface. This is most likely in the northwest portion of Orange county late Saturday night into early Sunday morning with little to no accumulation of freezing rain or sleet expected. A steady cold rain is expected for the rest of the forecast area through the day. PWAT values around 1 inch will allow for ample rainfall Sunday. QPF totals between 1.00-1.50 inches with isolated higher amounts will be possible. This could lead to nuisance street flooding and ponding of water in poor drainage areas.

The aforementioned low pressure system exits to the northeast by the late evening allowing a stable dry airmass to enter the forecast area overnight.

LONG TERM /MONDAY THROUGH THURSDAY/. Weak surface ridging builds in from high pressure over the Gulf of Mexico Monday, then pushes offshore on Tuesday.

A frontal system approaches for the middle of the week, lifting a warm front north of the area Tuesday night into early Wednesday morning. The associated cold front quickly moves through Wednesday into Wednesday night as the associated low passes well north and east of the area, tracking over the eastern Great Lakes region then into southeastern Canada. Temperatures will be warm enough at this point for all rain everywhere.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/. A strong cold front will move across the area during the next 2 to 3 hours, clearing eastern Long Island and southeast CT around 21Z.

Brief MVFR conditions possible with any showers, otherwise a VFR forecast.

Main forecast impact will be strong W-NW wind gusts up to 30 kt following the cold frontal passage and continuing into the first half of the evening before diminishing. Winds will then back around to the W/SW at 10 kt or less on Saturday. . NY Metro Enhanced Aviation Weather Support .

KJFK TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

KLGA TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

KEWR TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

KTEB TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

KHPN TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

KISP TAF Comments: Gusts may be more occasional until cold frontal passage. Brief IFR/MVFR conditions possible with any showers.

OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY. Saturday. VFR. Saturday night. IFR developing in in rain. Chance of freezing rain at KSWF. Sunday. Rain with MVFR/IFR. NW winds gusting to around 20-30 kt in the afternoon and evening, mainly at the coastal terminals. Sunday night-Tuesday. VFR. Tuesday Night-Wednesday. Chance of MVFR showers, mainly in the morning. W-NW winds gusting to around 20 kt in afternoon and night.

MARINE. SW flow ahead of an approaching cold front continues to increase on the waters this morning. SCA conditions will develop through the morning. The cold front moves across the waters in the afternoon with winds becoming W-NW and should be well east by early evening. Gale force winds are likely in the afternoon and evening on the waters east of Fire Island Inlet, Eastern LI Bays, and Eastern LI Sound. An occasional gale gust cannot be ruled out west of Fire Island Inlet. Gale warnings and Small Craft Advisories are in effect. Ocean seas will also build to 5 to 8 ft, highest east of Moriches Inlet. Winds slowly decrease overnight from west to east as high pressure builds to the south and west. Winds should be below SCA levels early Saturday morning. Seas also subside below SCA levels through tonight.

Sub-SCA conditions will occur on Saturday with high pressure near the waters. These conditions should continue into Saturday night with intensifying low pressure approaching the waters. The low moves across the waters Sunday morning and early afternoon and then quickly north and east away from the New England coast Sunday evening. Winds and seas should remain below SCA levels in the morning, but increasing NW winds on the backside of the low should bring SCA winds on all waters with potential for gale gusts on the ocean. Seas will also build in the afternoon as the low passes east. Elevated seas are then possible due to lingering swell into Monday morning. Otherwise, sub-SCA conditions are likely with high pressure over the waters.

HYDROLOGY. No hydrological concerns are expected through Saturday. Liquid equivalent amounts of 1.00"-1.50" are forecast from late Saturday into late Sunday as an area of low pressure impacts the region. There is some uncertainty with the amounts depending on the track and intensity of the low.

TIDES/COASTAL FLOODING. Astronomical tides will be increasing late this weekend due to a new moon early next week. An intensifying, fast moving low pressure system will also move across the region on Saturday night into Sunday. The quick movement of the system should prevent significant coastal impacts. However, minor coastal flooding is possible with Sunday morning high tide across the south shore back bays and Sunday afternoon high tide across the Western Sound.

Minor flooding benchmarks may be reached early next week due to the new moon.

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

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Small Craft Advisory until 5 AM EST Saturday for ANZ335-338- 345-355. Gale Warning until midnight EST tonight for ANZ330-340-350-353.
