Area Forecast Discussion National Weather Service New York NY 629 AM EST Mon Mar 8 2021

SYNOPSIS. High pressure will build over the area today will sink to the south late today. A warm front will approach tonight and lift through Tuesday morning, followed by a cold front Tuesday evening. High pressure will again build in later Tuesday night into Wednesday morning, then pass east later Wednesday into Thursday. A cold front will slowly approach on Friday and become stationary to the south by Saturday night. Unsettled weather should continue into the weekend as low pressure approaches from the Ohio valley.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Subsidence beneath the high will yield sunny skies, with high temps a couple of degrees above MOS, with mid 40s in NE NJ, lower 40s most elsewhere, and upper 30s across ern Long Island, SE CT, and the higher elevations elsewhere.

SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/. Clouds should slowly increase with the approach of the warm front tonight, becoming mostly cloudy after midnight. Low level WAA may be sufficient to produce a few sprinkles across eastern Long Island and SE CT late. The cloud cover should moderate low temps as compared to last night, low temps reached at or before midnight, then rising overnight tonight

After warm fropa, sunny skies expected, and with downslope flow and mixing up to 875 mb, temps should be on the mild side, with lower 60s in NE NJ and NYC, mid/upper 50s most elsewhere, and lower 50s near the south shore of eastern Long Island and SE CT. A back door cold front will be entering the area late in the day as a lobe of high pressure moves from the Great Lakes into northern PA and upstate NY, but with downslope NW flow (as opposed to shallow NE flow often seen with marine back door fronts) do not think temps will see much impact Tue night except NW of NYC, with lows there in the mid/upper 20s, 30s most elsewhere, and lower 40s in NYC.

Have forecast lower temps for Tue with a stronger subsidence inversion in place as the high moves across, followed by onshore flow as the high shifts east by afternoon. Highs on Wed should be a fairly uniform lower 50s near the coast and mid 50s inland.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. A SW return flow should develop by Thu, with a warming trend through Friday.

CPC ensemble mean forecasts continue to show convergence on a return to a positive NAO into the week. Guidance had held steady with H8 temps of of 8-10 deg C Thu/Fri, with the high slower to move east on Friday, thus maintaining SW flow for much of the day. As a result, and if increased cloud cover doesn't mitigate temps too much, Friday looks to be another mild day before a cool-down this weekend.

With SSTs in the lower 40s across the ocean waters, coupled with the SW wind component, coastal areas will not get as warm as the interior, and should remain in the mid 50s Thu/Fri. Record high temps do not appear in jeopardy.

By Fri afternoon, the ridge shifts to the east of the area with an upper trough passing over New England, and a sfc cold front passing through Fri night, with precip chances Fri afternoon/evening, albeit light. The front should then stall to the south as zonal flow aloft commences, and a deeper closed low takes shape across the Central Plains and moves east by Sunday. Cold advection behind the front will drop temperatures to more seasonable into Sunday.

The stalled boundary remains just south of the area on Sunday as a surface low develops over the OH Valley, keeping the area in clouds and light precipitation chances Sunday, especially Sunday morning. Temperatures may be marginally cold enough Sunday morning for a rain/snow mix across the interior, with plenty of time, still, to work out those details.

AVIATION /12Z MONDAY THROUGH FRIDAY/. VFR as high pressure builds to the south through this evening. A weak cold front approaches tonight, and passes through Tuesday morning.

NW-NNW winds around 10 kt through the morning push at NYC metro terminals. NW winds increasing to around 10 kt for outlying terminals. Winds back to the W/SW by late afternoon, then SW in the evening. SW winds 5-10 kt potential for south coastal terminals late tonight.

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

Timing of winds backing left of 310 magnetic in the afternoon could be off by 1 to 2 hours.

OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY. Tuesday. VFR. SW winds veering to W/NW Tue afternoon. Wednesday. VFR. Light winds NE/E winds AM, becoming SE PM. Wednesday Night. MVFR or lower in stratus possible for coastal terminals. Thursday. MVFR or lower AM coastal terminals, then VFR. S-SW gusts 15-20 kt. Friday. Mainly VFR. Chance of showers. S-SW gusts 20-25 kt.

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

MARINE. SW flow as a warm front passes late tonight into Tue AM could bring minimal SCA conds (both seas and wind gusts) to the ern ocean waters during that time frame.

By Thu afternoon, strengthening SW flow ahead of an approaching cold front will result in SCA conds on the ocean, with seas building to 5 ft and gusts 25-30 kt. Ocean seas will remain elevated into Saturday afternoon, with seas 5-7 ft and occasional gusts to 30 kt before diminishing late Saturday.

Ocean seas could begin to build again on Sunday evening, with occasional gusts to 25 kt.

HYDROLOGY. No hydrologic concerns are expected.
