Synopsis
Weak low pressure will remain in our region today before
drifting out over the ocean tonight. Hot humid high pressure is
forecast to build up from the southwest for Friday and the
weekend. A slow moving cold front approaching from the northwest
is expected to arrive on Monday, followed by an area of high
pressure from the west for the middle of the new week.

Near term until 6 pm this evening
This morning:
will continue to see isolated to scattered showers this
morning, due to a combination of the very moist airmass (as
evident by satellite model analysis pwats in the 2.3-2.4 inch
range) and lift ahead of the shortwave trough associated with
barry's remnant mid-lvl circulation. Don't expect these to be
intense due to lack of instability, however can't rule out some
brief locally heavy downpours given the moist airmass. Also will
have to watch out for patchy fog due to the low t TD spreads
but mid- lvl cloud cover may be an inhibiting factor.

This afternoon:
the mid-lvl shortwave will be somewhat slow to clear the area
today with perhaps some weak backside energy behind it. This
feature has helped spawn a weak low-lvl circulation to our nw,
which will drift SE over the area today. This low trough will
both help keep moisture in the area and also potentially act as
a focus for storms (via confluence). Consequently expect fairly
widespread convection to develop this afternoon with the
positioning of the low and moisture gradient perhaps favoring
the central half of our area (although really anywhere could see
storms). The main threat with these storms will be heavy rain
as pwats will remain over 2 inches, and will be combined with
cape values around 1500-2000 j kg, and deep (13-14k ft) warm
cloud layers. Did consider issuing a flash flood watch this
package, particularly over eastern pa where FFG was low, but
lacked sufficient confidence due to both instability concerns
(potential low-lvl cloud cover) and precipitation placement
concerns.

Although the hydro threat remains, feel the organized severe
threat will be lower today due to both lower instability and
fairly weak dynamics and shear (bulk shear generally 20 kts or
less). Obviously can never rule out some isolated strong
microburst storms in these kind of environments but anything
organized looks unlikely.

Due to the aforementioned cloud cover and precipitation,
temperatures will be a bit cooler today than any of the days
surrounding it, with highs generally in the upper 80s to lower
90s. However, still could get heat indices creeping towards 100+
in DELMARVA and the southern urban corridor due to the high
dewpoints.

Short term 6 pm this evening through 6 am Friday
The low-lvl circulation clears the area this evening, with
westerly flow behind it helping to filter in somewhat drier air
over the area. This eventually will result in diminishing
convective coverage, with most activity squashed by 04-06z. The
low-lvls remain relatively moist so patchy fog low stratus will
again be a possibility (particularly in areas that receive
precipitation during the day), and may be more widespread than
this morning due to faster clearing of mid-lvl clouds.

Long term Friday through Wednesday
On Friday, a mid level ridge is forecast to extend from the
south central states all the way out to the western atlantic.

The ridge is expected to remain in place into Saturday. A trough
is anticipated to begin digging over the great lakes and the
northeastern states on Sunday and the ridge should begin to
divide. Part of the ridge is forecast to push farther our over
the atlantic for the new week while part of it retrogrades back
over the western states. The pattern will keep our region in the
oppressive heat and humidity into the weekend with a noticeable
change in conditions by Tuesday and Wednesday.

We will continue the excessive heat warning for the urban
corridor through Sunday evening. Heat index values will likely
approach 100 today and they should get above 105 on Friday,
Saturday and Sunday. Saturday afternoon should be the most
oppressive with heat index values exceeding 110 in many
locations.

The excessive heat watch will remain in effect from noon on
Friday into Sunday evening for the remainder of our region.

Those areas should experience a slight reprieve from the
excessive heat and humidity today before both return for Friday
and the weekend.

We are expecting only a slight chance of a shower or
thunderstorm from the poconos and the lehigh valley into
northern and central new jersey late on Friday. There is little
chance for any precipitation on Saturday.

A cold front will begin to approach from the northwest. A pre-
frontal trough is anticipated to arrive on Sunday and it may
trigger the development of showers and thunderstorms in the
afternoon. The showers and thunderstorms will be the first step
in breaking the excessive heat and humidity.

The slow moving cold front is forecast to arrive in our region
on Monday before it slips to our south on Tuesday. We will
continue to mention a chance of showers and thunderstorms
throughout our region for Monday, confining the chance to
northeastern maryland, delaware and southern new jersey on
Tuesday.

High pressure and dry weather are expected for Wednesday.

High temperatures should settle mainly into the 80s for Tuesday
and Wednesday.

Aviation 08z Thursday through Monday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... A mixture of MVFRVFR conditions this morning will
transition to mostlyVFR after 12-13z. There will also be a
chance for lower flight categories this afternoon due to showers
and thunderstorms. Wind direction will be somewhat erratic
although speeds will generally be 5 kts or less outside of
thunderstorm outflows.

Tonight... Showers and thunderstorms should clear terminals by
about 03z and then a period of MVFR or even ifr conditions will
be possible overnight in fog stratus. Winds remain light and
variable.

Outlook...

Friday... Early morning visibility restrictions, otherwiseVFR.

Variable wind 5 knots or less, becoming southwest 5 to 10 knots.

Friday night... MainlyVFR with late night visibility
restrictions. Variable wind 5 knots or less.

Saturday... Early morning visibility restrictions, otherwise
vfr. Southwest to west wind 5 to 10 knots.

Saturday night... MainlyVFR with late night visibility
restrictions. Variable wind 5 knots or less.

Sunday... Early morning visibility restrictions, otherwiseVFR.

A chance of afternoon showers and thunderstorms. Southwest to
west wind 5 to 10 knots.

Sunday night... A chance of showers and thunderstorms with MVFR
or ifr conditions at times. Variable wind 5 knots or less.

Monday... A chance of showers and thunderstorms with MVFR or ifr
conditions at times. West to northwest wind 5 to 10 knots.

Marine
Sub-sca conditions are expected today and tonight although seas
may build to around 4 ft. Generally expect southerly winds
10-15 kts gusting to 20 kts or so. This afternoon into this
evening showers and thunderstorms will move into the waters and
potentially produce locally strong winds and higher seas.

Outlook...

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

Rip currents...

with a decreasing period, expect that the risk for the
formation of dangerous rip currents will be low today.

A variable wind on Friday morning should become southerly
around 10 to 15 mph in the afternoon. Breaking waves around 2
feet are expected along with a medium period south to southeast
swell. There should be a low risk for the development of
dangerous rip currents on Friday.
