Synopsis
A cold front will stall south of our area through today while
high pressure weakens to our west. A weak area of low pressure
slides near our region on Monday. High pressure builds across
the northeast Tuesday into Wednesday, then shifts southward
across the mid-atlantic region Thursday. The high is forecast to
shift to our south Friday, then offshore next weekend.

Near term through Monday
Afternoon forecast remains on track, so will make no significant
changes other than to make adjustments based on latest surface
obs.

Northwest flow aloft will become more established through
tonight as an upper-level trough in eastern canada sharpens some
across the northeast. Meanwhile, a weak surface cold front will
stall across the southern portions of our area with weak high
pressure remaining to our southwest. The short waves associated
with the trough remain to our north through tonight.

Some higher level clouds will arrive through the night from the
west within the gradually sharpening upper-level flow. A sea
breeze is resulting in some weak convergence within an area of
lingering deeper boundary layer moisture, therefore cloudiness
associated with it will dwindle late this afternoon as the
moisture mixes out some. There are some hints in the guidance,
mainly the nam, that some low clouds may try to develop offshore
and move into the coast overnight. This is of low confidence.

Low temperatures are mostly a blend of the statistical guidance
and continuity.

Short term Monday night through 6 pm Monday
An upper-level trough remains in place across eastern canada
and the northeast Monday. This will favor northwesterly flow
aloft and embedded within this flow is a weak disturbance with a
weak surface low reflection. This may be the remnant energy
associated with an MCS yesterday in the midwest (ongoing cloud
debris moving into the ohio valley). Some increase in the clouds
are expected, with this the most prevalent across the northern
portions of the area.

The majority of the guidance shows some shower potential with
the rather weak surface low as it tracks east-southeast from the
upper ohio valley to start the day to near DELMARVA by late
afternoon. This weak system should track along the weak stalled
surface front in the vicinity. The combination of all of these
weak systems along with our northern areas being near the right
entrance region of a mid level jet by late afternoon, should
result in some shower activity. The main focus for this is
across the west and northern areas where slight chance to low
chance pops are maintained for the afternoon. The 12z NAM shows
a rapid development in convection from the baltimore area to
southeastern pennsylvania after 21z, however this looks
overdone.

As for the high temperatures, opted for a model blend given some
additional variability. Highs in the mid to upper 80's south of the
lingering weak front. A sea breeze is expected once again.

Long term Monday night through Sunday
Synoptic overview:
an extended period of quiet weather looks likely over our area
for the long term. At the mid-lvls a fairly amplified ridge will
reside upstream of the area for essentially the entire long-
term period (although at times oscillating in orientation and
mean-position). At the surface the upstream ridge positioning
will promote anticyclogenesis with the initial surface high
centered north of the area. By the end of the workweek the high
will re-orient itself south of the area shifting the low-lvl
flow from onshore to offshore with a corresponding increase in
temperatures expected.

Dailies:
Monday night through Tuesday: the only chance of any
precipitation through the extended will be in the overnight
period Monday into Tuesday morning as a shortwave lifts
northeast of the area and an associated weak front moves through
the area. Given the clipping nature of the upper level system
capped pops at slight-chance with nothing significant expected.

The boundary will be largely south of the area by Tuesday
afternoon with highs generally in the 70s areawide.

Wednesday Thursday: should be dry and mild with onshore flow
prevailing. Highs will generally be near climo (low to mid 70s)
with lows in the low to mid 50s. Mostly sunny outside of some
occasional stratus (most prevalent near the coast).

Friday Saturday: the high will relocate south of the area
towards the late week-early weekend with the flow shifting more
westerly as a result. This will usher in a warming trend into
the weekend with maxes increasing into the upper 70s lower 80s
on Friday, and then increasing further into the mid 80s on
Saturday. Precipitation chances remain essentially nil. A
mostly quiet long term period is expected, with only a small
chance of precipitation at the beginning of the period..

Aviation 22z Sunday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Tonight...VFR overall. There is some potential that low clouds
develop overnight near the coast and reach acy, however this is
of low confidence. Light and variable to locally calm winds.

Monday... Some low clouds possible near the coast early,
otherwiseVFR with any ceilings mainly above 8000 feet. Some
showers possible in the afternoon mainly near and north west of
abe and rdg. Light and variable winds becoming west-northwest
4-8 knots in the morning, then turning southwesterly before
becoming northwest toward early evening.

Outlook...

Monday night... GenerallyVFR although some sub-vfr conditions
possible in showers lower clouds. Winds north-northeast 5-10kts.

Tuesday-Wednesday night... MostlyVFR during the day, with a
chance of MVFR conditions overnight in stratus. East to
northeast winds 5-10 knots
Thursday-Thursday night... GenerallyVFR conditions expected with
east-southeast winds 5-10 kts.

Marine
Conditions will remain below small craft advisory criteria
through Monday. A stalled weak front in the vicinity will result
in light enough flow for sea bay breeze influences and
therefore wind shifts to more southerly.

Outlook...

Monday night through Tuesday morning... Conditions are expected
to remain below advisory levels with seas around 3-4 ft. And ne
winds increasing to around 15 kts by Tuesday morning.

Tuesday-Thursday... SCA conditions potentially developing as
early as Tuesday but likely by Wednesday. Seas will increase to
5-7 ft by late Wednesday with northeasterly wind gusts likely
increasing to 25 kts or so as well.S
rip currents...

a moderate risk of dangerous rip currents continues into this
evening for the new jersey and delaware beaches. Southeasterly winds
around 10 mph with waves 3 to 4 feet in the surf zone.

For Monday, a low risk for the development of dangerous rip currents
is anticipated due to light southerly flow and waves of 2-3 feet in
the surf zone.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
