523 FXUS61 KOKX 010601 AFDOKX Area Forecast Discussion National Weather Service New York NY 201 AM EDT Sat Jun 1 2024 .SYNOPSIS... High pressure will be in control much of the weekend. A weak disturbance will approach late Sunday and move across Sunday night into Monday morning. High pressure will then take control of the weather through Wednesday before a cold front approaches on Thursday. && .NEAR TERM /THROUGH TONIGHT/... Skies remain clear overnight under building high pressure. Temperatures dip into the low-50s to low-60s for most, warmer than last night, under light NW flow. Dry conditions prevail everywhere. && .SHORT TERM /SUNDAY/... Surface high pressure centers itself over the area on Saturday with a ridge aloft. Temperatures continue to warm into the low/mid-80s for most about 5-10 degrees above average. Mostly sunny skies stay in place Saturday. A sea breeze may be more likely on Saturday due to the warmer temperatures, leading to temperatures dropping after its passage in the mid-late afternoon for many locations near the coast. As the ridge gradually weakens aloft and high pressure weakens in response to an approaching shortwave, cloud cover may increase very late into overnight Saturday. Ahead of the approaching shortwave, clouds will be mid-high level. Lows may not be affected much by them on Saturday night with lows in the mid-50s to mid-60s. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... High pressure will be offshore on Sunday, while the upper ridge flattens Sunday night into Monday as a shortwave moves across the area. The surface reflection shows weak low pressure passing just south of the forecast area. There is a chance of showers with this system, but there is also evidence of mid level capping. The 12Z ECMWF is still one of the more aggressive solutions with a convective complex dropping from NW to SE across the forecast area. Not quite buying into that solution at this time. Heights then build with upper ridging reestablishing itself through midweek with surface high pressure just off the Northeast coast. A frontal system then approaches for the end of the week as a northern stream upper vortex carves out a trough across the Great Lakes and into the Northeast. There are some timing differences in the guidance as can be expected this far out in time. Chances for showers and thunderstorms are in the forecast from Wednesday night into Thursday, with Thursday looking like the wetter of the days. While pretty much ran with the NBM for temperatures, noted in the box and whisker plots that the deterministic is generally running at the 25th percentile or even lower, especially through Tuesday. Yet, there are some large spreads between the 25th and 75th, with the median warmer in the 80s for most locations. However, having trouble going closer to the median as there is often ridging aloft with a subsidence inversion and onshore S/SE flow. The warmest day at this time looks to be Sunday, with closer to normal temperatures for the second half of the week. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...

High pressure continues to move into the region during the TAF period, with its center south of the area late Saturday into Saturday night. VFR conditions are expected through the TAF period. Wind speeds are expected to be mainly near or less than 10 kts much of the TAF period. Wind direction will initially be NW, or more variable going into early Saturday with winds becoming more W-SW with some coastal terminals expected to a sea breeze for afternoon into early evening. There is uncertainty with the timing of the sea breeze, making for a lower confidence wind direction forecast Saturday. KJFK, KLGA, KISP and KGON have highest chances of getting sea breezes. KBDR, KHPN, KEWR and KTEB have low chances of getting sea breezes. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Amendments possible for wind direction Saturday afternoon depending on the timing of the sea breeze. Sea breeze arrival time could be off by 1 to 2 hours. OUTLOOK FOR 00Z SUNDAY THROUGH WEDNESDAY... Saturday Night-Sunday Night: VFR through the day Sunday. MVFR or lower possible in showers Sunday night. Monday: VFR. Tuesday: Mainly VFR. Wednesday: Mainly VFR. MVFR or lower possible late in the day into Wednesday night in showers. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90
