281 FXUS61 KOKX 271724 AFDOKX Area Forecast Discussion National Weather Service New York NY 124 PM EDT Thu Jun 27 2024 .SYNOPSIS... High pressure will slowly build across through Friday. A warm front will lift north on Saturday, followed by a cold front on Sunday. High pressure will then return on Monday. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Dry as high pressure builds east. Seeing some sct-bkn Cu development across NYC and much of the interior mainly NW of NYC that should last through the afternoon. Should also see development along the sea breeze across Long Island this afternoon. High temps this afternoon will be in the 80s today. Lows tonight fall to the mid 50s to mid 60s under clear skies, with northerly flow 5-10 mph. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... High pressure remains over the region through much of Friday, before starting to shift east to the New England coast late Friday into Friday night. This will result in abundant sunshine with temperatures in the upper 70s to near 80, and dewpoints in the 40s. Temperatures Friday night will once again fall to the mid 50s to mid 60s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... High pressure will pass off the New England Coast Friday night, allowing a warm front to lift through on Saturday. An unsettled but very warm period will set up for Saturday night and Sunday as a prefrontal trough and cold front move through, bringing showers/tstms. The heat index may approach or surpass 95, mainly in NE NJ and perhaps also in NYC and along the north shore of Long Island, with temps approaching 90 and dewpoints in the lower 70s, but it is possible that limited daytime heating and/or better vertical mixing could lead to cooler temps and/or lower dewpoints so this remains uncertain, and at any rate would last for only one day. With the exception of Sunday, and possibly next Wednesday ahead of another cold front when temps will again be on the rise, temps should be close to normal. && .AVIATION /18Z THURSDAY THROUGH MONDAY/...
