.DISCUSSION...
KEY MESSAGE 1...The nor`easter slowly departs the region through
tonight.

The nor`easter is now centered south of Long Island, with high
pressure centered to the north. The low will continue to weaken
as it tracks slowly northeastward.

Winds have now weakened substantially compared to the past few
days, now only around 10 mph or so during the rest of the day
out of the N to NW. Still some spotty sprinkles out there, but
coverage continues to mostly dwindle. Cloud coverage will
linger through tonight into Tuesday, though gradually waning
through the period, with a few breaks possible this afternoon
and much better chance of some sun on Tuesday. That said, not
expecting a wall-to-wall sunny day just yet.


KEY MESSAGE 2... Coastal flooding threat lowered in many areas but
still a concern along the back bays of New Jersey and Delaware.

Overall, tidal flooding concerns continue to diminish as winds have
shifted offshore. Additional flooding at high tides is expected to
be spotty minor for most locations.

With that being said, the Coastal Flood Advisory for Cape May,
Atlantic, Monmouth, and Middlesex counties in NJ have been allowed
to expire and additional coastal flooding headlines are not
anticipated here.

Moderate flooding of back bays continues to affect Ocean County NJ
and Sussex County DE. Given the offshore flow, water levels should
be receding from here. However, minor flooding is expected to
persist through tonight and into Tuesday. A Coastal Flood Advisory
is in effect until 2 PM Tuesday for these locations.


KEY MESSAGE 3...Unsettled weather possible Friday through
Sunday.

A cold front is forecast to move across the area late Friday into
Friday night. As it moves into the area, there will be a chance of
showers. However, as the vorticity impulse aloft weakens, the
showers may dissipate for many areas as the move eastward. However,
additional rain fall is expected to move back into the area Saturday
night into Sunday. An area of low pressure is forecast to develop
along the front as it stalls to our south Saturday, then move
northward across the area through Sunday. Showers will increase
Saturday night into Sunday as a couple of short wave/vorticity
impulses move into the area, along with the surface low
pressure.
