High pressure will build toward the area through Friday, and remain in control through Saturday as it moves off the Mid Atlantic coast. 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/...
-- Changed Discussion --
A mostly sunny start to today with high pressure building in. Some mid level clouds may move across the area, especially inland and across Long Island this afternoon. N flow 10-15 mph with a few gusts to 20 mph should back NW by afternoon, and there may be a SW sea breeze along the immediate south coastlines late this afternoon. High temps today should be on the warm side, near 80 in urban NE NJ and in the mid/upper 70s elsewhere. Skies become mostly clear tonight, with NW winds diminishing to 5-10 mph through this evening in the metro area and becoming light elsewhere. Low temps will range from the lower 60s in NYC, to the upper 40s in the interior valleys and Long Island Pine Barrens.

&& .SHORT TERM /SATURDAY THROUGH SUNDAY/... High pressure sfc and aloft will be in control this weekend, with temps reaching 80-85 in most areas both days. Most south facing coastlines should remain on the cooler 70s, less so on Sat with a prevailing W-NW flow, more so on Sunday as a 10-15 kt S sea breeze develops in the afternoon. An approaching shortwave trough could get close enough to yield a slight chance of showers by late day Sunday west of the Hudson River. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
Upper ridge flattens Sunday night into Monday as a shortwave approaches from the west. Associated weak low center is progged to pass not too far south of us during this period. Chance of showers with this system through Monday morning, with the highest overall chances for southern sections. Heights aloft recover somewhat in the wake of the shortwave Monday night and Tuesday before falling slowly on Wednesday. Mainly dry through this period with subsidence and capping, but cannot rule out a shower north and west of the city Tuesday and Wednesday afternoons where there`s a chance of a little CAPE building. A better chance of showers and thunderstorms arrives on Thursday with the approach of a cold front and pre-frontal trough. NBM was used for temperatures. Each day will feature highs above normal, ranging mostly from the mid 70s to lower 80s.
