Synopsis
Strong low pressure will gradually work its way across the canadian
maritimes today and tonight. Meanwhile, high pressure will build
into the ohio valley today then just to our south tonight and
Sunday. A cold front will settle southeastward across our area late
Sunday night and Monday while a weak area of low pressure tracks
along it. High pressure builds in Tuesday and Wednesday before
slowly shifting eastward later Thursday and Friday.

Near term until 6 pm this evening
Increased wind gusts just a bit in the far north to account for
observations in that area showing a peak gust of 58 mph at high
point nj (1800 feet asl) and certainly not respresentative of
the entire area. Vsbl satellite imagery shows cloud cover moving
out with the departing low, and is represented very well by the
current forecast. Temperatures also look on track, so no major
changes to the current forecast package.

Previous near term discussion below... .

Strong low pressure will drift to the northeast across canada's
maritime provinces and the gulf of saint lawrence today.

Meanwhile, high pressure will build from the western great lakes
and the ohio river valley toward the carolinas. The tight
pressure gradient between the two features will maintain a
strong west northwest wind in our region. Sustained wind speeds
should range from 15 to 25 mph with gusts up to 30 or 40 mph.

Wind speeds are forecast to begin slowly diminishing during the
course of the afternoon.

Clouds are expected to linger through about mid morning, especially
over parts of eastern pennsylvania and new jersey. Very dry air will
build into our region for this afternoon, with a clear sky
anticipated at that time.

Maximum temperatures are expected to range from the lower 40s on the
pocono plateau to the middle 50s in southern delaware.

Short term 6 pm this evening through 6 am Sunday
The strong low will move farther away to our northeast tonight as
high pressure settles in the carolinas and virginia. We are
anticipating a clear sky. The west northwest wind is forecast to
decrease to less than 10 mph early this evening with the wind
becoming light and variable overnight.

The ideal radiating conditions should allow temperatures to fall
into the 20s in much of our region. Readings may not drop below the
lower 30s in urban locations and in areas near the coast and
bays.

Long term Sunday through Friday
Summary... Mainly some rain later Sunday night and Monday with a cold
front and wave of weak low pressure; cooler Tuesday; warming takes
place Wednesday through Friday.

Synoptic overview... A large upper-level trough amplifies across new
england later Sunday and Monday with a cold front pressing
southeastward across our region. A trough remains in the east
through Tuesday, then the flow becomes more zonal for a time. An
upper-level trough amplifies into the plains toward late next week,
building a ridge to the east.

For Sunday and Monday... Surface high pressure is forecast to be
shifting east of the carolinas Sunday. An upper-level trough
amplifies across eastern canada and eventually into the northeast,
with a cold front arriving in our area Sunday night and Monday
morning. There looks to be limited moisture with the cold front,
however some showers should occur as it arrives. A short wave
embedded within the northwesterly flow aloft tracks from the midwest
Sunday to the mid-atlantic coast by late Monday. This eventually
looks to get absorbed with the incoming amplifying trough, however a
weak surface low associated with it tracks along the aforementioned
surface cold front as it settles southeastward.

While the guidance does vary some with how much shower activity
accompanies the front, the bulk of the guidance focuses more
precipitation with the wave of low pressure. The QPF looks to be on
the lighter side as the system should be moving right along. The
majority of this is anticipated to be rain, however if enough
cooling arrives across the north some snow could mix in. Overall
though it looks like the colder air arrives after the majority of
the precipitation ends. In addition, much drier air looks to move in
a bit faster from south to north during Monday and this should also
help to keep the more organized precipitation becoming more focused
across the southern areas with time. Prior to the arrival of the
cold front, a milder flow will occur Sunday allowing temperatures
away from the coast to get well into the 50s to near 60 degrees,
then cooling occurs during Monday and especially Monday night when
it turns colder.

For Tuesday... As an upper-level trough amplifies across the east,
some ridging across the midwest will drive an expansive high
pressure system eastward into our area during Tuesday. This should
drive much drier air southward despite a northeast low-level flow.

As a result, any precipitation lingering across the DELMARVA early
should rapidly end as low pressure moves out to sea. Our sensible
weather is then dominated by the aformentioned surface high building
over and to our north and northeast through Tuesday night, and this
will keep a chilly airmass in place.

For Wednesday through Friday... Looks like a sliver of tranquil
weather for our area as surface high pressure becomes entrenched
across our area and extends to the northeast. This is between an
eventual trough that ejects out into the plains toward the end of
the week, and low pressure east of the southeast coast. The trough
out west eventually will send low pressure northeastward from the
southern plains, however that will probably not approach until later
Friday night. In the meantime, a warming trend is expected to take
place after a chilly to cold start. The warming however may be
slowed closer to the coast given the surface winds may retain an
onshore component longer. For now, kept some rather low pops
especially for the western areas by late Friday.

Aviation 13z Saturday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today...VFR. Decreasing clouds this morning, clear this afternoon.

West northwest wind 16 to 22 knots with gusts of 28 to 36 knots.

knots becoming variable 6 knots or less.

Outlook...

Sunday...VFR as clouds increase and lower, especially at night. Some
showers possible toward daybreak Monday. West-southwest winds 10
knots or less.

Monday...VFR ceilings, which may briefly lower to MVFR with some
rain especially from the phl area southward. West-northwest winds
becoming northerly around 10 knots.

Tuesday and Wednesday...VFR. Northeast winds around 10 knots,
becoming east to southeast less than 10 knots by later
Wednesday.

Marine
A west northwest wind at 20 to 30 knots is forecast to continue for
much of the day. Frequent gusts in the 30 to 40 knot range are
expected. Wind speeds will likely begin to decrease slowly this
afternoon. We will keep the gale warning in place until 6:00 pm for
the coastal waters of new jersey and delaware and for delaware bay.

The west northwest wind will continue to diminish tonight, with
conditions anticipated to fall below small craft advisory levels
shortly after midnight.

Outlook...

Sunday and Monday... The conditions are anticipated to be below small
craft advisory, however northeast winds increase later Monday night
and may gust to around 25 knots.

Tuesday... Small craft advisory conditions probable for a time,
especially for the atlantic coastal waters where seas will be around
5 feet.

Wednesday... The winds are anticipated to be below small craft
advisory criteria, however seas may linger around 5 feet especially
in the southern atlantic coastal waters.

Phi watches warnings advisories
