| Area Forecast Discussion National Weather Service New York NY 403pm EDT Monday Jun 15 2026 .WHAT HAS CHANGED... No significant changes at this time. .KEY MESSAGES... 1) Dry conditions along with seasonable temperatures are expected overall through Tuesday night. 2) Water levels will be close to minor coastal flood benchmarks through Wednesday for the nighttime high tide cycles. 3) Warm front Wednesday into Wednesday night may give a round of showers, isolated thunderstorm. 4) A strong low pressure system will bring a cold front with an increase of winds and make for potential severe weather Thursday. .KEY MESSAGE 1... High pressure builds in from the west through tonight. The high pressure area moves into Western Atlantic Tuesday into Tuesday night. Dry conditions expected through Tuesday night with high pressure in control. Temperatures near seasonable average for most locations. Exception tonight with rural outlying locations, radiational cooling, more below average temperatures. Tonight, more vast range of lows, upper 40s to near 50 for the rural outlying locations to lower 60s within parts of NYC. .KEY MESSAGE 2... Still have high astronomical tides through midweek but getting relatively farther away from the new moon so these levels will slightly lower. Water levels close to minor coastal flood benchmarks for high tide cycles at night for portions of western shorelines. Coastal flood statement remains for tonight for parts of NY Harbor, Western Long Island Sound and South Shore Bays shorelines. Offshore flow limits the total water levels tonight but more southerly flow Tuesday night brings the total water levels back up. .KEY MESSAGE 3... Warm air advection aloft will help with development of showers associated with warm front moving in. A thunderstorm will be possible. Instability will be quite limited with the southeast flow. Temperatures cooler Wednesday with more S to SE flow and more maritime influence along the coast. .KEY MESSAGE 4... Strong low pressure moving from Ontario to Quebec Thursday. Models showing low dropping to near 990mb. The cold front will be strong and approach the area. Southerly flow in low levels increases, becomes gusty, making for relatively cooler temperatures across Southern CT and Long Island, warmer across NE NJ, into Lower Hudson Valley and NYC. The cold front approaching will make for increasing chances of showers and thunderstorms Thursday and cold front moves across Thursday night into early Friday. Chances of showers and thunderstorms lower by late Thursday night. This will be limited CAPE but high shear environment. Possible severe thunderstorms Thursday into early Thursday evening, with main threat being damaging winds. Storm Prediction Center has the 15 percent severe risk for much of the area. Marine Below SCA (Small Craft Advisory) level conditions are expected through midweek with high pressure influence. SCA (Small Craft Advisory) level conditions become more likely Thursday into Thursday night with the strong cold front approach and crossing through. Maybe even some possible low end gale force wind gusts are possible Thursday into Thursday night. SCA (Small Craft Advisory) conditions should last into Thu night on the ocean and the eastern Sound and bays of Long Island into Thu evening, with ocean seas 6-8 ft and SW winds gusting to 25-30 kt. Thereafter, 5-7 ft seas should linger on the ocean waters E of Fire Island Inlet for the rest of Thu night, with 5-ft seas E of Moriches Inlet still possible daytime Fri. Rip currents: A moderate risk of rip current development is expected today and Tuesday with a lingering 2 to 3 ft light southerly swell.
