Area Forecast Discussion National Weather Service New York NY 419 AM EST Sat Feb 27 2021

SYNOPSIS. A frontal system with a low pressure area moves across the region this afternoon. Weak high pressure quickly follows for tonight before another wave of low pressure moves in for Sunday into Sunday night. The frontal system associated with this low moves across by early Monday. A cold front passes through during the afternoon to evening hours on Monday. High pressure then returns for Tuesday. Low pressure then passes to our south Wednesday into Wednesday night, otherwise high pressure remains in control through Thursday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Wintry precipitation for interior locations will be ongoing until 13-14Z this morning with plain rain for the coastal portions of the region. The primary precipitation type for interior areas is snow but a transition to sleet and freezing rain is forecast going into early this morning. Total snow accumulations near 1 inch or less for interior with ice accumulations of just a glaze.

Coastal areas will be warmer from the surface SE winds and the interior locations will have more low level cold air because of the higher terrain preventing the warmer SE flow from infiltrating into the interior locations. Winds will be relatively lighter for these interior locations.

After 14Z, expecting rain for the entire area and this will last until mid to late afternoon as surface winds become more westerly.

Forecast highs were a combination of blended model data and a consensus of raw model data with values ranging from the low 40s in far interior locations to near 50 for NYC Metro and Long Island.

SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/. High pressure briefly moves overhead tonight with its subsidence leading to initially mostly clear conditions but with a gradual increase in clouds as the night progresses. Dry conditions are forecast.

The next wave of low pressure approaches for Sunday with another round of mainly rain starting mid to late Sunday morning and lasting through the day. If precipitation starts early enough, brief light wintry precipitation is possible for Orange County NY, otherwise this will be an all rain event. The low pressure moves across Sunday night with an associated frontal system also moving through. There will be an associated cold front slowly moving through the region going from Sunday night into Monday morning. Rain chances linger across the region and for the coastal areas on Monday.

Drier conditions eventually settle into place Monday as the cold front pushes farther southeast of Long Island. A steep pressure gradient will be setting up between a strong low pressure area in the Canadian Maritimes and a strong high moving into the Southern parts of the Great Lakes.

Forecast lows tonight were a blend of blended model data and MOS guidance since there will be some radiational cooling before clouds increase overnight into Sunday morning. Forecast lows range from near 30 for interior and Pine Barrens of Long Island to near 40 for NYC Metro.

Forecast highs on Sunday and forecast lows Sunday night use more a consensus of raw model data to minimize the diurnal temperature range.

A warmer day is expected for Monday with forecast highs in the upper 40s to lower 50s with gusty westerly winds.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. The cold front passes through dry either late Monday afternoon or Monday evening. Breezy conditions develop, and NW winds will likely gust through the night as the strongest cold advection sets in. An upper trough axis and shortwave will be passing through as well Monday night. Not much moisture depicted by the models during this time, but will leave in a chance of flurries.

Deep-layered ridging then occurs for Tuesday with dry conditions and below normal temperatures. ECMWF/GFSv16/GDPS show low pressure passing well to our south during the Wednesday to Wednesday night period. Overall, a drier trend from 24 hours ago, but will leave in low chances of rain for the period, focused toward the southern zones. High pressure otherwise dominates through Thursday with dry weather and above normal high temperatures. Low confidence forecast for Friday, but for now will go with slight chance PoPs with the potential of a cold front or wave of low pressure brining PCPN to the area.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/. A frontal system will move across the area on today. High pressure briefly returns tonight.

conditions have begun to lower from VFR to MVFR, and will continue to fall to IFR by mid to late morning. Mainly rain will coincide with these lowering flight categories, however, a brief 2 to 3 hour window of mixed precipitation is expected at KSWF. Also, a brief period so snow or mixed precipitation is expected at KHPN, but this should not last as long. VFR conditions return toward 00Z Sunday.

SE winds less than 10 kt will back to the E/SE, increasing to around 10 kt toward daybreak at the coast. A frontal wave will move across the area in the afternoon with winds briefly going and light and variable before becoming W/SW at 5 to 10 kt from 21Z to 22Z. Winds then veer to the WNW in Saturday evening.

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

Timing of IFR may be off 1-2 hours. Possible southerly LLWS after 12Z, ending from west to east by 21Z.

OUTLOOK FOR 06Z SUNDAY THROUGH WEDNESDAY. Late Saturday Night. VFR. Sunday. Mainly VFR in the morning. MVFR or lower with a chance of rain in the afternoon and at night. Monday. VFR. W wind G20-25kt in aft. NW wind G30-35kt possible eve and night. Tuesday. VFR. NW wind G20-25kt possible. Wednesday. Low chance of MVFR in rain.

Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90

MARINE. An area of low pressure will pass over the waters today. As a result, winds and waves will increase, resulting in small craft conditions (winds and seas) on the ocean waters. The non-ocean waters will remain below SCA levels.

SE swells are expected to keep ocean seas at SCA levels through all of Sunday and into Sunday night, potentially continuing into Monday. Westerly winds increase through the day Monday ahead of a cold front. The strongest cold air advection and gusts occur during Monday night behind the front's passage. Gale force gusts are looking more likely during the night for some, if not all of the waters during the night and may last into a part of Tuesday morning. Thereafter, high pressure then settles in with more tranquil conditions for Tuesday Night. Low pressure is expected to pass well to the south on Wednesday into Wednesday night. While winds might not be much of a concern, there is still a chance that a swell pushes wave heights into advisory criteria on the ocean.

HYDROLOGY. First precipitation event through this afternoon will result in rain amounts around a quarter to half inch with locally higher amounts possible, mainly in the form of rain.

Second precipitation event Sunday through Monday is forecast to produce mainly rain again, amounting up to around half to one inch with locally higher amounts possible once again. For those more interior locations, combination of snow melt and the rain may lead to some minor flooding but otherwise no hydrologic impacts are expected.
