Area Forecast Discussion National Weather Service New York NY 146 AM EST Sat Nov 28 2020

SYNOPSIS. High pressure builds in for the remainder of the weekend. Developing low pressure across the southeast Sunday night will deepen on Monday as it tracks into the northeast. The low will meander near the Great Lakes region Monday night into Tuesday, before tracking into southeast Canada on Wednesday and Thursday. High pressure returns for the end of the week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Clouds have managed to dissipate or shift out of some of the forecast area over the past couple of hours. Expecting the sky to vary between mostly cloudy and mostly clear through night. Adjusted hourly temperatures and dewpoints along with the cloud cover as temps have been allowed to drop more quickly than previously forecast due to clearing in some areas. Still thinking lows generally be in the upper 30s to low 40s throughout the CWA, though some spots closer to the NYC metro may remain in the middle 40s.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. A weak cold front moves through the area on Saturday with perhaps some breaks in the clouds. A few hi-res models do show the potential for some light passing showers by Saturday morning mainly for CT and the Lower Hudson Valley, but confidence on these is low and as such, decided to keep out of the forecast.

Either way, clouds should be fairly persistent through much of the day with gradual clearing into the afternoon. Winds will remain out of the NW and may pick up a bit during the afternoon as the pressure gradient tightens between the departing trough to the east and high pressure building in from the west. High temperatures will remain slightly above average, as they have for the last several days, with values in the middle to upper 50s in the NYC metro and Long Island with values in the low to middle 50s in the Lower Hudson Valley and CT.

Skies become mostly clear by Saturday night as high pressure builds in from the west. Though winds may be a bit brisk out of the NW, the potential for rapid radiational cooling exists for anywhere the wind can become calm for any period of time. Areas with the highest potential to cool are areas away from the coastline.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. The 11/27 12z model suite has continue to come into better overall agreement through early next week. The main weather story will be with a deepening low pressure that tracks well to our west on Monday, sending a strong frontal system across the region on Monday night. This system will bring an all rain event, but a widespread soaking rainfall is expected.

Sunday will be dry with slightly above average for this time of year with surface high pressure along the eastern Seaboard. Highs will be in the lower to middle 50s.

A southern stream upper low and vort max currently over the Four Corners region will track eastward this weekend and begin interacting with a progressive and digging northern stream shortwave Sunday night. The southern stream vort max will then phase into the northern stream by Monday night, becoming a larger upper cyclone. The timing of the phasing has slowed down since 24 hours ago. This has led to a bit weaker surface low pressure that deepens on as it tracks up the Appalachians to the northeast on Monday.

The low will send its associated warm front across the region Monday afternoon with widespread rain beginning Monday morning and continuing into the afternoon. The associated triple point will move across the region Monday evening which will effectively bring in drier air aloft and end the widespread rain. The rain may be locally heavy at times, especially Monday afternoon and evening. Due to the large scale synoptic forcing and some very weak instability, a rumble of thunder cannot be ruled out. The low level wind field also strengthens in the afternoon and evening, which could bring wind gusts 35 to 40 mph near the coast. Will have to monitor if portions of the area get fully into the warm sector which could bring a slightly better chance of thunderstorms. The chance for any wind headlines appears low at this time. The slower development of the overall system along appears to keep the strongest winds well to our south and east.

The main frontal system moving east of the area Monday night occurs with the drying aloft, significantly decreasing the coverage of rain. Winds should also weaken Monday night as the pressure gradient relaxes with the main surface low situated well to our northwest.

On Tuesday, an impressive vort max within the deep and anomalous upper low approaches the region. As the vort max and cold pocket aloft associated with the upper low moves overhead, there could be a few showers that develop in the afternoon. Otherwise, temperatures will slowly trend downward into Tuesday night. The upper low and surface low lift up into southeast Canada by Tuesday. Our region will still be within cyclonic flow aloft. Other than some scattered to broken clouds, dry conditions are forecast.

Surface high pressure returns for the end of the week. There may be another strong southern stream system developing across the Plains on Friday, but any impacts from this system would occur next weekend if this feature were to verify as currently modeled.

The warmest temperatures next week occur on Monday as strong southerly flow brings readings into the upper 50s and lower 60s. Temperatures trend downward the rest of the week with highs below normal on Wednesday and Thursday in the 40s.

AVIATION /06Z SATURDAY THROUGH WEDNESDAY/. VFR with high pressure in control. Light NW winds overnight will back WNW after sunrise, then increase this afternoon to around/just over 10 kt with gusts just under 20 kt this afternoon.

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

No unscheduled AMD expected.

OUTLOOK FOR 06Z SUNDAY THROUGH WEDNESDAY. ***HIGH IMPACT EVENT LIKELY MONDAY AFTERNOON/EVENING*** Tonight through Sunday night. VFR. Monday. IFR in rain. SE-S winds 20-30kt G35-50kt afternoon/evening, with LLWS up to 50-65kt, and chance thunder. Worst cond near the coast. Speeds a few kt lower at KSWF. Tuesday. MVFR conds with sct showers. S-SW winds G15-20kt inland and 20-25kt NYC metros/coast. Wednesday. VFR. SW winds G20kt.

MARINE. Winds and seas will remain relatively calm and below SCA criteria under high pressure building into the area for the weekend. Sub SCA conditions are likely Sunday into Sunday night. Gales are possible on all waters Monday into Monday night. However, the highest probability of seeing gales may be on the ocean waters and possibly eastern Long Island Sound and eastern Long Island Bays. Will continue to mention potential in the HWO. Ocean seas will rapidly build on Monday, becoming 8 to 12 ft Monday night. High ocean seas should then continue through Tuesday night. Winds will weaken Monday night into Tuesday with small craft conditions most likely on the ocean. Small craft conditions on the ocean may continue on Wednesday.

HYDROLOGY. A period of moderate to heavy rain is expected Monday into Monday evening. A widespread 1 to 2 inch rainfall is forecast, which could lead to some minor urban flooding.

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