| Area Forecast Discussion National Weather Service New York NY 935am EST Tuesday Jan 20 2026 .WHAT HAS CHANGED... No significant changes made to forecast. .KEY MESSAGES... 1.) Temperatures remain below normal through at least early next week with the exception of Thursday. 2.) Potential for snow late Saturday into Sunday. .KEY MESSAGE 1... Some of the coldest air of the season builds into the region today with temperatures only reaching the lower and middle 20s. A gusty west wind will make it feel even cold with wind chill values only in the single digits. This is about 15 to 20 degrees below normal. As high pressure builds in tonight, wind diminish and lows will get into the single digits inland and the lower teens at the coast. As the high slides east and a return flow sets up, temperatures warm a bit on Wednesday and then a few degrees further on Thursday. Highs on Wednesday will be in the upper 20s and 30s. Thursday will be the warmest day of the week with highs in the upper 30s and lower 40s. A cold front moves across the region late Thursday, followed by a second on Friday evening. It will be this second cold front that brings a modified Arctic air mass into the area for the weekend. Highs on Friday will be in the middle 20s to lower 30s. The weekend and start of next week will see highs only in the teens and lower 20s. Overnight lows will fall into the single digits. .KEY MESSAGE 2... We will continue to monitor a low pressure system moving out of the middle portion of the country which is expected to move off the Middle Atlantic coast early Sunday morning and pass south of long island during the day Sunday. With plenty of cold air in place, any precipitation will be in the form of snow. The question is how far north the precipitation field from this low reaches. 00z GFS/CMC has the area seeing a period of snow during this period. Will continue to stick close to the NBM guidance. The forecast carries a chance of snow from Sat night into Sunday night, though it is still way too early to get into specifics. Marine A gusty west flow will produce SCA (Small Craft Advisory) conditions across all waters today, persisting on the ocean through the early morning hours Wednesday. Seas on the ocean are expected to build as high as 5 to 9 ft, highest east of Moriches Inlet due to the westerly fetch. Waves on the sound will get up to 3 to 5 ft. Winds and seas will begin to gradually subside tonight. Some freezing spray is possible from through at least the first part of tonight. A brief lull Wednesday morning will be replaced by a strengthening SW flow in the afternoon with the return of SCA (Small Craft Advisory) conditions on the ocean waters. The SCA (Small Craft Advisory) conditions will continue on the ocean through Friday morning ahead of and behind a cold frontal passage, with SW-W flow gusting to 25 kt and seas 5-7 ft. An Arctic cold frontal passage Friday afternoon should then bring SCA (Small Craft Advisory) conditions to all waters Friday afternoon/night, with NW flow gusting to 25-30 kt and occasional gusts to 35 kt on the ocean, and seas 5-6 ft. SCA (Small Craft Advisory) conditions should continue on the ocean Sat into Sat night, with NW-N flow gusting to 25-30 kt. A few gusts to 25 kt may also be possible on the non ocean waters as well Sat night. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None.
