Synopsis
Low pressure will track across the great lakes and into canada
tonight and Monday, pulling a cold front across our region Monday
afternoon and evening. High pressure then builds in for Tuesday into
Wednesday. A warm front arrives in our area late Thursday night and
Friday, followed by a cold front during Saturday which may then
stall to our south Sunday.

Near term until 6 am this morning
Showers and thunderstorms have moved across the northwestern
portions of the CWA this past afternoon and evening. The severe
thunderstorm watch has since expired and the severe threat is
coming to a close. A few thunderstorms are lingering in the
lehigh valley and into north jersey, but these storms should
continue to wane and are not expected to be severe. Dangerous
lightning is still accompanying these storms, however. Another
complex of thunderstorms is moving into berks and chester
counties, but these storms will remain sub-severe and continue
to weaken over the next several hours.

Heavy rain has fallen across portions of the lehigh valley and
into the poconos, thus several flash flood warnings remain in
effect for these areas. Turn around, don't drown!
after the showers and thunderstorms lift to the northeast of our
region, we are anticipating a partly cloudy sky for late tonight.

A south wind around 10 to 15 mph this evening should diminish and
become southwest late tonight. Temperatures will remain quite mild
with lows in mid to upper 60s.

Short term 6 am this morning through 6 pm Tuesday
A cold front is forecast to approach from the northwest late on
Monday. The wind is expected to settle into the west southwest with
speeds increasing into the 10 to 20 mph range with gusts of around
25 mph. The gusty wind is anticipated to begin mixing somewhat drier
air down from aloft. Dew point readings should fall from the middle
and upper 60s in the morning to around 60 late in the afternoon at
most locations.

Regardless of the subtle drop in low level moisture and the drying
aloft, there should be enough instability in the afternoon to
trigger the development of scattered showers and thunderstorms.

Mixed layer CAPE vales are forecast to increase around 600 to 1000
j kg.

Another warm day is expected with highs mostly in the 80s.

Long term Tuesday night through Sunday
Summary... Cooler with much lower humidity Tuesday into Wednesday,
then some warming. Some convective chances at times, however no
significant storm systems are anticipated.

Synoptic overview... An upper-level trough in eastern canada into the
great lakes swings across the northeast Monday night, and even
strengthens some across the northeast Tuesday before shifting east.

Another strong upper-level trough lifts across the plains Tuesday
and Wednesday resulting in a building ridge nearing the east. The
ridge builds more Thursday into Friday, although short wave energy
topping it will keep more of a northwesterly flow aloft regime
across the northeast. At the surface, a cold front shifts offshore
Monday evening with lowering dew points and cooler air. The pattern
looks to generally repeat from Thursday onward as a warm front
arrives followed by a cold front during Saturday.

For Monday night... An upper-level trough will slide across the
northeast with the center of it into adjacent canada. A cold front
is forecast to shift offshore early in the evening, ending any
showers and thunderstorms. A few thunderstorms could be on the
strong side early with gusty winds. Much drier and also cooler air
will start to advect into the area under a northwesterly breeze.

For Tuesday and Wednesday... As a robust trough exits the northeast
late Tuesday, ridging builds from the great lakes region southward
ahead of a strong upper-level trough moving into the central plains.

This will allow surface high pressure to build into our area from
the northwest, with a cooler and much drier airmass in place. There
will be a breeze on Tuesday from the northwest given mixing within
some cold air advection. As the ridge builds eastward more
Wednesday, the surface high will shift eastward as well and tend to
move offshore Wednesday night. A warm front advancing northeastward
from the ohio valley will start to approach our area late Wednesday
night. As a result, the dew points should start to creep up some
Wednesday night however it is not expected to be all that humid.

For Thursday and Friday... A strong ridge centered across the
southeastern u.S. Will flex north and eastward some during this time
frame. The axis of this ridge may end up remaining to our west,
keeping our region more into a northwesterly flow regime aloft. As a
result, a warm front sitting to our southwest may take its time
advancing north of our entire area until late Friday. In addition, a
strong short wave diving southeastward may produce weak surface low
pressure near our area later Thursday night and Friday morning
before moving offshore. It is possible this feature could be
convectively enhanced, and the convective risk may be higher during
this time frame. Given uncertainty on the evolution of this, kept
pops on the lower side. Otherwise, dew points will gradually be on
the rise with it turning more humid especially during Friday.

For Saturday and Sunday... As an upper-level trough rounds the
northern side of the large ridge, surface low pressure tracks across
canada however its cold front is forecast to move across our area
later Saturday. The tail end of this front may be weaker as it
encounters the northern side of the ridge, however building warmth
and humidity along with a belt of stronger flow may result in some
stronger convection with the front. The front may then stall to our
south Sunday given the strong ridge across the southern states.

Aviation 06z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Into tonight... MainlyVFR at krdg and kabe with one exception. A
few lingering showers and thunderstorms at these sites, thus
temporary MVFR and ifr conditions are possible. MainlyVFR at
kphl, kilg, kmiv, kpne and kttn with only a chance of a shower
or thunderstorm in the 05z to 08z time frame. Low clouds off
the ocean into this evening at and around kacy at times,
otherwiseVFR through the night. Southwesterly wind 5 to 10
knots. Low level wind shear is anticipated at kphl, kilg, kpne,
kttn, kacy and kmiv between about 02z and 08z due to a
southwesterly low level jet around 40 knots.

Monday... MainlyVFR. A chance of a shower or thunderstorm in the
afternoon with the greatest chances being at all sites except
rdg and abe. West southwest wind 10 to 15 knots with gusts
around 25 knots possible after the 14-16z time frame.

Outlook...

Monday night... A few showers and thunderstorms during the early
evening may result in local but brief MVFR ifr conditions, otherwise
vfr. West winds 10-15 knots, becoming northwest.

Tuesday and Wednesday...VFR. Northwest winds 10-15 knots with gusts
to 20 knots, diminishing some Tuesday night, then becoming light and
variable during Wednesday.

Thursday and Friday... MostlyVFR, however some showers and
thunderstorms are possible especially later Thursday into Friday.

Light and variable winds becoming west-southwest 5-10 knots
Thursday, then becoming northwest later Thursday night into
Friday.

Marine
A south to southwest flow will continue over the coastal waters of
new jersey and delaware for tonight and Monday. With the warm air
riding over the cold water, winds are not forecast to mix
efficiently to the water's surface. It appears as though gusts will
not get much higher than 20 knots. As a result, we have cancelled
the small craft advisory. Wave heights on our ocean waters are
expected to be 2 to 4 feet and waves on delaware bay should be 2
feet or less.

The warm humid air may also result in the development of some fog on
the waters. However, the timing and extent are a low confidence
forecast. We will continue to monitor for any fog development.

Outlook...

Monday night... The conditions are expected to be below small craft
advisory criteria, with winds shifting from southwest to northwest
following the passage of a cold front.

Tuesday... Northwest winds gusting to around 20 knots, however the
conditions are expected to be below small craft advisory criteria.

Wednesday through Friday... The conditions are anticipated to be
below small craft advisory criteria.

Rip currents...

the southerly flow will continue to result in a moderate risk for
the development of dangerous rip currents along the new jersey coast
into tonight. There is a low risk at the delaware beaches. With a
similar weather pattern expected for Monday, the same risk
categories are anticipated.

Equipment
The kdix radar has returned to service, however problems may
still be encountered as all of the issues have not been
completely remedied. Further outages are possible until further
testing has been completed. In case of an outage, surrounding
radars include kdox, kokx, klwx, kccx, kbgm and tphl.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
