.SYNOPSIS...
Low pressure over eastern Ontario will progress to the east with its
associated cold front passing through our region tonight into
early tomorrow morning. The low should then move northeastward
towards Canada's Maritime Provinces on Tuesday and Tuesday
night. A secondary cold front will on Wednesday evening with
high pressure arriving in its wake for Thursday and Friday.
Another cold front is expected to approach from the northwest on
Saturday and it should pass through our region on Saturday
night and could stall just to our south into Sunday.

&&

.NEAR TERM /THROUGH TUESDAY/...
Severe Thunderstorm Watch 270 remains in effect this evening
through 9 pm EDT for all of eastern PA except Carbon and
Monroe counties, northern and central NJ. Severe Thunderstorm
Watch 273 is in effect for all of Delaware, the Delaware Bay and
portions of southern NJ. Damaging winds will remain the primary
threat this evening while marginally severe hail cannot be
ruled out.

Showers developed along a line where we were able to see partial
clearing this afternoon ahead of the cold front. This enabled
instability to ramp up quite a bit although I think that area is
starting to stabilize this evening over Carbon/Monroe counties
as we can already see the outflow boundary racing south on TPHL.
Most of the convection this evening for our area is likely
producing 25-35 mph winds. Heading into later this evening as
the front starts to slide south we anticipate another round of
convection as we'll see a strengthening shortwave currently
progressing through central and southern PA as evidenced on W/V.
This shortwave should provide enough lift to see a line
organize and tap into better forcing aloft.

Bulk shear vectors based on the RAP are in the neighborhood of
50 kts across southeastern PA and both storm motion and anvil
relative flow look boundary parallel. This suggests that the
linear convective features being depicted by the latest HRRR and
18z NAMNest are reasonable as approximations for how the rest of
the evening will unfold.

Lapse rates will continue to steepen this evening from north to
south as damaging winds continue to be the primary threat this
evening. With the enhanced lapse rates, slightly better
instability, stronger bulk sheer, and better forcing, the
highest threat for severe weather will generally be from Trenton
and south this evening.

As the earlier shift indicated, the tornado threat will be
limited by the weak low- lvl wind fields (the wind field is very
"mid- lvl heavy" in this event). Heavy rain is certainly a
concern with any stronger convection with some signal for 1-2+
inch an hour rates, however suspect that the quick system motion
will make the hydro threat secondary to the wind threat.

For Tuesday, the axis of a short wave rotating around the
trough is forecast to pass overhead early on Tuesday afternoon.
As a result, we will keep a chance of showers in the forecast.
There will continue to be some weak instability at that time so
we will also mention a slight chance of thunder.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
The period from Tuesday night through Thursday will feature a fairly
sharp mid level trough extending southward from Quebec over the
eastern states. The main axis of this trough looks to pass through
by Tuesday night resulting in mainly dry weather for this time
period.

Tuesday night into Wednesday, the region will be situated between
high pressure over the midwest and low pressure over Atlantic
Canada. This will set up a dry air advection pattern with lowering
dew points and skies that will generally be mainly clear to partly
cloudy. Lows Tuesday night will be mainly in the 50s to around 60
with highs Wednesday mainly in the 70s to near 80.

High pressure builds in for Wednesday night and Thursday bringing
continuing mainly clear skies with temperatures a little on the cool
side for this time of year as lows will be mainly in the 50s with
highs mainly in the 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The mid level trough moves out to sea Thursday night with some
ridging from the southwest and west arriving overhead on Friday.
Another mid level trough is expected to progress from Ontario and
the Great Lakes through the northeastern states over the weekend.

At the surface, high pressure is forecast to slide off the coast
Thursday night into Friday. It should remain dry Friday with
readings likely getting into the lower and middle 80s at most
locations as the return flow on the back side of the high begins to
bring warmer air into our region.

A cold front associated with the weekend's mid level trough is
anticipated to approach from the northwest on Saturday before
passing through our region on Saturday night. As a result, we will
mention a chance of showers and thunderstorms at that time for
Saturday afternoon/evening. The front may stall near or just south
of the region Sunday into Monday but forecast details remain
uncertain at this time. Will keep in at least a slight chance of
showers across most of the region for both days.

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...Thunderstorms are progressing eastward this evening
with the potential for some of the to become strong to severe,
and continuing through the early overnight period. Best timing
is generally through 05Z, before the storms exit to the east of
the terminals. Strong, gusty winds with the potential for small
hail through tonight along with low MVFR to IFR cigs and vis.
Conditions remain low MVFR to IFR (possibly LIFR at times)
behind the storms and continuing through the rest of the night.
Southwest winds ahead of the storms may become slightly more
southerly before becoming light and variable overnight. Winds
will start to trend more to the northwest towards morning.
Moderate confidence in the overall forecast, low confidence in
timing/coverage of storms.

Tuesday...MVFR/IFR conditions expected across the southern half
of the region to continue through 14-15Z before improvement to
VFR starts to occur for all terminals. Northwest winds around 5
to 10 knots in the morning will increase to 10 to 15 knots with
gusts around 20 knots through the afternoon. Slight chance for
some showers or thunderstorms but confidence to low to include
even a VC at this time. Moderate confidence.

Outlook...

Wednesday...VFR. Northwest wind around 10 knots. High
confidence.

Thursday...VFR. Northwest wind 5 to 10 knots. High confidence.

Friday...VFR. Southwest wind around 10 knots. High confidence.

Saturday...Mainly VFR except restrictions possible in late day
showers/storms. SW winds 10 to 15 knots. Moderate confidence.

&&

.MARINE...
Sub-SCA conditions will prevail through Monday night with seas
running 2-3 ft and southerly winds around 10-15kts. There will
be potential for thunderstorms with locally strong winds tonight
over all waters.

Outlook...

Tuesday through Friday...No marine headlines are anticipated.

Saturday...Southwest winds will increase and could get near SCA
levels by late day.

Rip currents...

The risk of dangerous rip currents is expected to remain
borderline Low-Moderate through Tuesday given 2-3 ft breakers,
and medium-period low amplitude shore-perpendicular easterly
swell. We have issued a MODERATE risk for NJ with a LOW risk
for Delaware for Tuesday.
