Synopsis
A cold front over our region will shift off shore later today.

By Wednesday, a large area of high pressure is expected to build
towards our region. This high will remain near our region
through the weekend.

Near term until 6 pm this evening
Flash flood watch has been cancelled with this update. Latest
high res guidance shows that the heaviest rain should be done in
our area. Additionally, with the front now on the coastal
plains, and quickly sinking southeast, it will be difficult to
see much convection, and thus convective heavy rain rates.

Behind the front we are already seeing dry and cold air
advection (most notably with dew points below 70 as far east as
the western suburbs). This front will continue to progress
through the morning, and should be off shore by late this
morning. Forecast highs today are close to what the lows were
just a few days ago! Highs are expected to be in the 70s for the
entire region.

Due to the front lingering near the region, and the mid and
upper level short wave trough still west of our region, we will
continue to see a few rounds of rain through the day. However,
rounds of rain today are not expected to be nearly as impactful
as what we saw last evening. For one thing, instability will be
very limited (so much so, that it appears that only DELMARVA and
the coastal plains of nj will have a chance for thunderstorms -
for the rest of the area, it should be mostly showers).

Additionally, there will be dry air advection, not just at the
surface behind the front, but also in the mid levels.

Consequently, with a decreasing precipitable water value, the
threat for heavy rain will decrease as well.

Short term 6 pm this evening through 6 am Wednesday
One last round of showers is possible overnight, primarily for
coastal locations, as the mid and upper level short wave trough
shifts further southeast. With dry air advection continuing, the
heavy rain threat should be minimal by this evening.

Temperatures will be near normal overnight, but in comparison to
overnight lows the last several days, it may feel a bit cool!
lows should range from the mid 50s to mid 60s across the area.

Long term Wednesday through Monday
Overview...

an extended stretch of mainly dry and seasonable weather is expected
for most of this week and into the weekend. At upper levels, a
lingering trough will remain over the east from Wednesday into
Thursday. This trough will weaken and shift southward through the
week as a ridge moves out of the great lakes and builds into
southern canada and new england. At the surface, a broad region of
high pressure will exist downstream the ridge and upstream the
trough. This high will start the midweek period over the midwest,
and as the upper level features slowly shift, the high will
gradually make its way eastward. It will not crest over our region
until the weekend. Even by early next week, we will probably
continue to feel the influence of this high. The resulting sensible
weather is something we really have not seen much of this year:
several consecutive days (at least) of dry and quiet weather.

Temperatures also look near normal for this period, as we are
between cooler than normal air to the south associated with the
lingering trough, and much warmer than normal air that will
build in with the ridge well to our north.

Dailies...

Wednesday... Our early week frontal system will still be departing
on Wednesday, and it looks like considerable cloud cover and
possibly some light showers may linger towards the coast especially
in the morning. As a wave of low pressure moves offshore, some
guidance is even hinting at an inverted-trough like feature which
could throw some light showers back into coastal nj. However, the
trend for the day will be clearing skies and drier weather,
especially to the west. Temperatures only getting into the low 80s
in most areas with the cooler air behind the front.

Wednesday night-Saturday... Dry and quiet. A very gradual warming
trend in 850mb temperatures should yield a slow warming trend at the
surface, with each day generally a degree or two warmer than the
previous but no warmer than the upper 80s by Saturday. Dew points
should remain comfortable also, with those also showing just a slow
uptrend heading towards the weekend but remaining well away from
the oppressive territory we have seen.

Sunday-Monday... Temperatures should continue coming up slowly
during this period, with some 90s potentially returning to the
picture. Humidity will also continue to creep up, but . A weak
frontal system may approach on Sunday, with possibly some showers up
north. However, high pressure still looks to be the dominant feature
into early next week, and we will likely have to wait until later in
the week to see any more robust frontal systems.

Aviation 10z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today... MostlyVFR conditions are expected (guidance continues
to show some MVFR or even ifr ceilings over the region, but that
has yet to develop, and the window for that is closing). There
may be some brief MVFR conditions as periods of light rain are
possible. Northwesterly winds just behind the cold front,
becoming light and variable late today.

Tuesday night... MostlyVFR conditions are expected, with light
and variable winds.

Outlook...

Wednesday... MainlyVFR, except MVFR possible at least through the
morning at miv and acy. Winds north-northeast at 5 to 10 kt.

Wednesday night-Saturday... An extended period of quiet,VFR
conditions is expected. Winds mainly light and variable, favoring
light easterly flow if anything.

Marine
Small craft advisory conditions on all the waters are expected
to continue through the morning. By this afternoon, expect winds
and seas on all the waters to be below SCA criteria.

Outlook...

Wednesday-Saturday... Winds and seas are expected to remain below
sca criteria. 3 to 4 foot seas Wednesday diminish to mainly 2 to 3
feet for the remainder of the period.

Rip currents...

winds will be shifting to the nw-n as the cold front passes over
the coast this morning. The resulting risk for the development
of dangerous rip currents will be low across the new jersey
shore and delaware beaches.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... Small craft advisory until noon edt today for anz430-431-
