A trough will remain over the region through tonight. High pressure will then build into the region for Wednesday and Thursday.

Another low develops along the coast Saturday and moves to the north and east of the area through Sunday. High pressure will follow early next week.

&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
An upper level trough will remain over there region today with another shortwave approaching and moving across the region. Like yesterday, while it will remain mostly dry, can not rule out a few light rain showers, mainly during the afternoon/evening hours. Otherwise, we should see more clouds than sun today, with high temperatures in the upper 50s and lower to middle 60s. Tonight, while the upper trough remains over the area, surface high pressure will start to build in from the southwest. Some clearing is expected, especially late tonight. It will remain dry, with lows in the 40s and lower 50s. A few of the far outlying, normally cooler could see a few low readings in the upper 30s.

&& .SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
-- Changed Discussion --
The upper trough finally starts to lift NE early Wednesday with building heights through the short term period. At the surface, high pressure will continue to build into the region, which will remain over the area through Thursday. Overall, looking at sunny conditions both Wednesday and Thursday, with gradual warming both days. Expect highs on Wednesday in the lower to middle 60s. On Thursday, expect m middle to upper 60s. Can not rule out a few 70 degree readings in and around the NJ/NYC metro area for Thursday. Lows Wednesday night will be in the 40s and lower 50s. Once again, can not rule out a few upper 30s at the normally cooler locations.

&& .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
-- Changed Discussion --
An amplifying upper trough over the upper midwest into the mid Mississippi Valley continues moving eastward Thursday night and deepens into a full latitude trough by Friday morning. Global model guidance remains divergent with the evolution of the main low tracking to the east, and then the subsequent development of low pressure along the triple point along the Delmarva coast. Timing, placement, and strength of the developing coastal low are uncertain. However, precipitation is still expected to begin late Thursday night and continue into Saturday night, and possibly early Sunday. n With the uncertainties have stayed with the NBM through the extended period. Behind the low a strong and gusty west to northwest flow develops as the low tracks north and east and high pressure builds to the west. With the area still on track for measurable precipitation into Saturday this would mark the 7th consecutive weekend of rainfall at Central Park.

-- Changed Discussion --
With a weak pressure gradient over the area waters, expect sub-SCA conditions through the middle of the week. A frontal system impacting the waters Friday into Saturday, with an increasing southeasterly flow, will likely produce SCA seas on the ocean waters Saturday. As a low develops off the Delmarva Saturday and strengthens and tracks to the north and east a gusty west to northwest flow develops and may produce SCA conditions across all the waters late Saturday night into Sunday. At this time gusts remain below gale force across the waters for Sunday.
