Synopsis
A cold front will continue to slowly push south as high pressure
builds to our north through early next week. The high will try to
spread down the east coast, but not fully make it into the area. The
high will retreat north and east next Tuesday and Wednesday. This
will allow an area of low pressure to lift northward off the eastern
seaboard during the mid week period and a cold front to track
through the area later next week.

Near term until 6 am Saturday morning
As expected most of the early precipitation has cleared our
area, with low-mid lvl cloud cover also retreating
southeastward as considerably drier air (pwats in the 0.6-0.7
inch range) filters in the from the nw. Consequently expect a
dry night over the vast majority of the area with limited cloud
cover apart from cirrus. The lone exception may be southern
delmarva and far southern nj where some low-mid lvl cloud cover
may persist a few more hours. Also can't completely rule out
some weak showers over southern DELMARVA tonight as a frontal
wave pushes out to sea, but expect this activity to largely
stay offshore.

Otherwise should be a fairly cool night with mins in the
50s to lower 60s with the warmest lows in the urban corridor,
delmarva, and coastal nj. Northerly winds may increase a bit
after about midnight which may not allow us to get quite as cool
as this airmass would support (although we will still be below
normal).

Short term 6 am Saturday morning through 6 pm Saturday
High pressure is forecast to be located in eastern ontario and
southern quebec on Saturday. The air mass is anticipated to
expand southward into our region.

We are expecting a mostly sunny sky for eastern pennsylvania and
northern new jersey. Partly sunny conditions are forecast for
northeastern maryland, delaware and southern new jersey. There is a
slight chance of a light shower in the afternoon in those areas due
to the onshore flow, but most locations will remain dry.

A northeast wind at 8 to 14 mph is expected for Saturday. Highs will
likely favor the 75 to 80 degree range with low humidity levels.

Long term Saturday night through Friday
Cooler conditions everywhere with small pops across the coastal
plain will start the long term period. An increase in temperatures
and greater chances of precipitation will return by the middle of
next week and persist through late week.

As we start the weekend, Saturday is expected to be a september-like
day. High pressure will be building to our north across eastern
canada, with our area on the far southern edge. This will keep an
easterly flow across the area, and as a trough low aloft moves
across the area, temperatures will cool to near or below normal.

Dewpoints will be in the comfortable 50s. Dry weather is expected,
with mainly afternoon evening clouds due to the trough low moving
overhead. The exception could be the nj coast and DELMARVA as the
onshore flow helps to produce some light rain.

As we move into Sunday and Monday, the easterly flow will continue
as high pressure builds a little farther southward across new
england. The high will try to nose its way down the east coat toward
the mid atlantic region during this time as well. Guidance continues
to indicate precipitation developing across the area during this
period, so we will have a slight chance chance of showers Sunday
through Monday. However, it may just end up being more cloudy rather
than rainy as some stratocumulus clouds could develop with the
persistent easterly flow. Regardless, if it does rain, it is
expected to be light as pw values are mostly an inch or less.

As we move into Tuesday through Thursday, unsettled weather could
return to the area. An area of low pressure is forecast to be
lifting northward off the east coast Tuesday through Thursday. At
the same time, a cold front is expected to approach from the west
during the day Wednesday into Thursday. There are some timing
differences with these systems. However, there will be an increasing
chance of showers and thunderstorms starting Tuesday and continuing
through Thursday.

With the region expected to be behind the cold front on Friday,
precipitation chances will be on the decline. Little temperature
change is expected at the moment behind the front.

Aviation 01z Saturday through Wednesday
Tonight...VFR with a decrease in cloud cover. Northerly wind 5 to 10
knots.

Saturday...VFR. North to northeast wind around 10 knots.

Outlook...

Saturday night... MainlyVFR conditions expected. MVFR conditions
possible at kacy and kmiv as an onshore flow generates some clouds.

Winds generally NE 5-10 knots.

Sunday... MainlyVFR conditions expected. MVFR conditions possible at
kacy and kmiv as an onshore flow generates some clouds drizzle light
rain. Low confidence. NE winds 5-10 kts with gusts up to 20 knots
possible.

Sunday night-Tuesday... More widespread MVFR conditions developing
with the persistent onshore flow. E to NE winds 5-10 kts with gusts
up to 20 kts possible.

Wednesday... MainlyVFR as the onshore loses its grip across the
region. Winds less than 10 kts.

Marine
A northerly wind around 10 to 15 knots for tonight is expected to
become northeast 15 to 20 knots on Saturday. Wave heights on our
ocean waters should build around 4 feet. Our current forecast is
borderline for a small craft advisory on Saturday. If wind and wave
conditions appear to begin trending higher than anticipated, we may
eventually need to issue a small craft advisory for Saturday on our
ocean waters.

Outlook...

Saturday night... Low end SCA conditions possible due to long fetch e
to NE winds developing.

Sunday-Wednesday... A prolonged low end SCA may be needed through the
period as long fetch E to NE winds persist.

Rip currents...

increasing northeasterly winds and seas building to around 4 ft
by the afternoon will result in a moderate risk of rip
currents on Saturday.

This elevated rip current risk (either moderate or at times
high) is expected to persist beyond Saturday until at least
Tuesday as a prolonged period of onshore flow and elevated seas
looks likely.

Tides coastal flooding
A prolonged northeast to east flow is expected Saturday through at
least Tuesday. This persistent onshore fetch, combined with
increasing astronomical tides due to an approaching new moon on
Thursday will likely lead to increasing coastal water levels.

Guidance is already indicating that minor coastal flooding is
becoming more likely Monday and Tuesday over delaware bay and
portions of the nj shore.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
