.SYNOPSIS...
-- Changed Discussion --

High pressure will then build across the region Wednesday night into next weekend.

&& .NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
-- Changed Discussion --
Periods of rain will continue through tonight as an area of low pressure approaches the region from the southwest. Rainfall amounts will remain light, generally under one half inch through Monday morning. Temperatures will remain nearly steady or perhaps rise a few degrees overnight as a warm front tries to approach the region. Lows will range from the mid 40s across typically cooler locations across the interior to the mid 50s across the NYC metro and Long Island.

&& .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
-- Changed Discussion --
Rain will continue on Monday morning as the low crosses the region before tapering off Monday afternoon as the low moves off to the northeast and its associated cold front pushes offshore. Highs on Monday will range from the mid 50s inland to around 60 at the coast. In the wake of the front, winds will shift to the NW, ushering in a cooler air mass for Monday night. With a cold air advection regime in place, overnight lows will range from the low to mid 30s across typically colder interior locations to around 40 elsewhere. Can`t rule out some frost formation Monday night across the interior if winds diminish quickly enough.

&& .LONG TERM /TUESDAY THROUGH SUNDAY/...
-- Changed Discussion --
A nearly full latitude longwave trough will be track through the eastern United States Tuesday through Wednesday night. The global guidance is keeping the developing offshore deepening low a little farther east in response to the progressive upper trough. And the surface low associated with a strong vort max rotating into the upper trough will be weakening Tuesday and Tuesday night as the offshore surface low quickly deepens. While the global guidance is mostly dry as the offshore low is farther east, the NBM is keeping probabilities. Have used a blend of the NBM and global guidance. Otherwise high pressure will be dominating Wednesday into the upcoming upcoming weekend.

&& .MARINE...
-- Changed Discussion --
Small Craft Advisories remain in effect for the ocean waters east of Fire Island Inlet through tonight as seas are expected to briefly build to 5-6 feet. Seas then subside during the day on Monday, but marginal SCA conditions could briefly return on the ocean waters Monday night as winds increase in the wake of the departing low. Winds and seas across the forecast waters will be below SCA levels Tuesday and Tuesday night. With a deepening low moving to the south and east of the forecast waters Tuesday night through Wednesday small craft conditions are expected to develop on the ocean waters Wednesday morning, and continue through Wednesday night. The eastern ocean zone is most likely to experience SCA conditions with SCA conditions possible on the Long Island eastern bays, and maybe the far eastern Long Island Sound. Thursday through Friday night winds and seas remain below advisory levels on all the forecast waters.

&& .HYDROLOGY...
-- Changed Discussion --
Light rainfall will continue into the day on Monday, with additional rainfall amounts generally remaining less than one half inch. One tenth to three tenths of an inch of rainfall is possible Tuesday night into Wednesday, with around a tenth of an inch across the lower Hudson Valley, into northeastern New Jersey and the New York City metro area, and the highest amounts expected across southeastern Connecticut and eastern Long Island. Otherwise dry weather is expected Wednesday night into Sunday morning. No hydrologic impacts are expected.

&& .TIDES/COASTAL FLOODING...
-- Changed Discussion --
Astronomical tides will continue to increase into early next week and additional minor coastal flooding appears likely during the morning/early afternoon high tides into at least Tuesday. With water levels expected to be slightly higher on Monday compared to what was observed this morning, a Coastal Flood Advisory is now in effect for Southern Queens/Nassau, Brooklyn, Staten Island, and portions of northeast New Jersey as well as southern Fairfield County in Connecticut. Water levels are expected to exceed minor flood thresholds in these areas with the Monday morning/early afternoon high tide. In addition, Coastal Flood Statements are in effect for Manhattan, northern Queens, the Bronx, and southern Westchester during the same time period as water levels may approach or just touch minor flooding benchmarks.
