| Area Forecast Discussion National Weather Service New York NY 930pm EST Thu Dec 4 2025 Synopsis Strong high pressure builds in from the west tonight into Friday. The high will pass east Friday night as weak low pressure passes well to the south Friday night and heads well out to sea on Saturday. A cold front moves through Sunday night. Behind it, high pressure builds in from the west, remaining in control through Tuesday. Low pressure may impact the area mid next week as it passes to the north. Near Term - Until 6am Friday Morning NW winds 15-20 mph with gusts 25-35 mph near the coast will quickly diminish through 1am with winds becoming light early Friday morning as high pressure settles over the area. Temperatures plummet tonight thanks to arctic high pressure building in behind the cold front, reaching the single digits in some spots well inland, teens most elsewhere, and the lower 20s in/just outside NYC and out by Montauk. Some record low temps may be approached or set. Wind chills will be in the teens this evening with the strongest winds. While winds will be lighter towards early morning, wind chills in the single digits are possible. Short Term - 6am Friday Morning Through Saturday Night Key Points: * Cold conditions continue, especially daytime Friday. * Weak low pressure passing well south may brush the area with some light snow/rain Friday night into Saturday. Temps on Fri as the high builds across will only reach the mid/upper 20s inland, lower 30s most elsewhere, and the mid 30s across eastern Long Island. Still maintaining a 30-40 Probability of Precipitation as the precipitation shield with a southern stream low passing off Hatteras and moving nearly due E out to sea skirts the area. Precip type should be mostly light snow with little to no accumulation Fri night, then light rain or a rain/snow mix on Sat as temps warm and mid levels dry out. The best chance for precipitation looks to be after midnight Friday night as an inverted trough extending from the low moves into the region. Low temps Fri night will be in the teens to 20S, with lower 30s expected in NYC. Lows Saturday night into Sunday morning will be a couple of degrees warmer. Highs on Sat will be in the upper 30s/lower 40s. Long Term - Sunday Through Thursday Key Points: * Some of the coldest air of the season so far moves in early next week. High temperatures Monday and Tuesday likely in the upper 20 and 30s region-wide, with morning wind chills in the single digits and teens. * A period of precipitation is possible Sunday night into Monday, and could bring light snow to portions of the area should it occur, mainly north of the I-95 corridor. Troughing aloft across much of the Eastern US to start the period. A cold front moves across the area Sunday night that ushers in a modifying arctic air mass through early next week. While the frontal passage, at this time, appears moisture starved, still have to monitor this period as there are differences amongst guidance handling two separate shortwaves traversing east. The 12Z GFS/GEFS depicts more interaction with these waves, inducing surface low development off the New England coast on Monday, and bringing a period of light rain and snow to the region. Other guidance is much more separated and drier as a result, and this wetter solution is being considered an outlier with this update. Still a period to watch though over the next couple of days as these differences resolve. Regardless thereafter, 1030 mb surface high builds east over the Mid Atlantic into Tuesday, keeping conditions cold and dry locally. Daytime highs both Monday and Tuesday look to remain mostly in the 30s, or even 20s inland, and a gusty NW flow behind the front will add to the cold. Morning wind chills Tuesday could fall into the single digits to near 0 inland, and teens along the coast, which would not warrant any cold headlines. A clipper system may move through the Northeast on Wednesday, bringing the next chance for precipitation. Marine NW gales will continue on the ocean east of Moriches Inlet and on LI Sound east of the Mouth of the CT River through 1am. Elsewhere, SCA (Small Craft Advisory) conditions will continue through 1am. Once the gales end, SCA (Small Craft Advisory) conditions are expected through 6am on the ocean east of Moriches Inlet. Winds and seas quickly subside on Saturday and will remain below SCA (Small Craft Advisory) levels through Sunday. Small Craft Advisory (SCA) conditions likely return to all waters Sunday night into Monday as NW flow increases behind a cold frontal passage. Gusts near or above 25 kt look to persist into Monday evening before subsiding, then sub SCA (Small Craft Advisory) conditions expected on all waters once again into midweek. Hydrology No hydrologic impacts are expected through much of next week. Tides / Coastal Flooding Water levels may touch minor flood thresholds at the Bridgeport and Stamford CT tide gauges with the midday high tide on Sat as low pressure passes well south. Climate Low temps Fri morning may reach daily record lows at KJFK/KBDR, and may also get close at KLGA. High temps Fri may also be close to daily record low maxes at KLGA/KJFK. Record Low Temperatures: KEWR: 15/1935 KBDR: 17/1989 KNYC: 11/1926 KLGA: 21/1942 KJFK: 20/1966 KISP: 13/1966 Record Low Maximum Temperatures: KEWR: 31/2002 KBDR: 28/2002 KNYC: 22/1886 KLGA: 32/2002 KJFK: 33/2007 KISP: 30/2002 NOAA New York NY Office: Watches - Warnings - Advisories CT...None.
