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
The cold front extended from the waters off the DELMARVA coast,
across far southeastern maryland to central virginia at mid
afternoon. The boundary will continue to sink to the south this
evening and overnight. The band of showers streaming across
northeastern maryland, delaware and southern new jersey will also
drift southward. Conditions continue to stabilize in our region,
even across our far southern counties. However, there will remain
some instability nearby to our south into the early evening so we
have allowed for scattered thunder in parts of talbot county and
caroline county in maryland, as well as in parts of southern
delaware and on the adjacent waters.

The cloud cover is forecast to erode gradually from north to south
over our region. The wind should favor the northwest to northeast
quadrant at 10 mph or less.

Low temperatures are expected to range from around 50 in the
elevated terrain of the poconos an far northern new jersey, to
around 60 on the coastal plain of eastern maryland, delaware and
southern new jersey.

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 20z Friday through Wednesday
Into this evening... MainlyVFR. Scattered showers may bring periods
of MVFR conditions to kmiv and kacy. Northwest to north wind 8 knots
or less.

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...

a north wind around 10 mph is forecast into this evening. Breaking
waves around 3 feet are anticipated along with a medium period
southerly swell. There is a low risk for the development of
dangerous rip currents.

A long duration northeast to east wind is expected for the weekend
and into the early part of the new week. As a result, we are
anticipating a prolonged period with an enhanced risk for the
development of dangerous rip currents from Saturday through at least
Tuesday.

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. Some
delaware bay guidance is already indicating that minor coastal
flooding is becoming more likely Monday and Tuesday.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
