&& .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... High pressure will continue to build in on Friday. Another mid level trough will pass to the south on Friday which could lead to a period of mostly cloudy skies in the afternoon across NYC metro, but expect dry conditions. High temps are a couple of degrees above the warmer MOS guidance numbers, with lower/mid 80s in most places, and upper 70s along south facing shorelines out east. Low temps Friday night should be similar to those forecast for tonight. There is a moderate risk for rip current development today on Atlantic facing beaches on Friday. && .LONG TERM /SATURDAY THROUGH THURSDAY/... High pressure builds in from the north and west on Saturday and slowly moves overhead on Sunday before moving offshore on Monday.

In addition, a light pressure gradient and the combination of warm land temp and relative cooler water temps will likely result in afternoon seabreezes. Highs along the coast may only reach the lower 80s. A cold front approaches on Monday, slowly working its way across the Northeast from Monday night through Tuesday night. Cold front should be clear of the region by Wednesday. Will continue to carry chance POP for showers and thunderstorms for the passage of this front.
