.DISCUSSION...

Low pressure will continue to push off the NJ coast later this morning
and into the afternoon resulting in downsloping north to northwest
flow. Meanwhile, weak high pressure will build in at the surface allowing
for clearing skies and drier conditions. The gradient between the departing
low pressure system and incumbent high will result in breezy conditions
across the incident location later this morning and into the afternoon.

Winds will shift from the northwest early this morning to the north
mid-morning and into the afternoon hours. Sustained speeds of 5 to
15 knots can be expected with gusts up to 25 kts during mid
to late afternoon. Small Craft Advisories are in effect from 0800 this
morning until 2200 tonight. Winds will drop off overnight into Friday
as weak high pressure sits south of the incident location. Conditions
will remain dry with increasing clouds Friday morning. Shower chances and
perhaps a thunderstorm return Friday evening and into the overnight hours
as a warm front approaches the region.

VFR ceilings are expected this morning with few to scattered clouds around
3000 feet. Scattered to broken ceilings between 5 to 10 kft are expected
this afternoon and early evening before lowering once again tonight.

Tide levels will decrease today with northerly flow. Water levels will
rise again Friday into Saturday under southeasterly flow. No tidal flooding
is expected through Friday.

The current water temperature is around 65 degrees.
