Synopsis
A bermuda high will build off the east coast through the remainder
of the weekend and into the middle of next week. With the mid-
atlantic on its northwest periphery, a warm, humid, and unsettled
pattern will develop. A weak upper level disturbance will pass to
our north on Sunday. A weak frontal boundary will approach late
Monday and stall over the region by Tuesday. A stronger cold front
will approach on Thursday and move offshore by Friday. High pressure
will build in for the end of the week.

Near term until 6 am Sunday morning
Radar and surface observations indicate that the sea breeze
front has advanced to the delaware river, and the combination
sea breeze and delaware bay breeze has encroached into
maryland's eastern shore. These breezes will dissipate as the
sun sets this evening. Shower thunderstorm activity across the
cwa is also waning, but a few widely scattered hit-or-miss
showers are still possible this evening, so have reduced chance
pops to slight chance in the south and have kept chance pops in
the north as remnants from the decaying MCS may still clip this
area overnight. Have also tweaked temperatures to match current
conditions. Otherwise... Previous forecast is on track.

Previous near term discussion below...

stationary front remains south of delmarva, and low pressure will
ride along this boundary and out to sea. Meanwhile, some mid-level
shortwave energy will pass through the region this evening.

With a prolonged period with high temperatures of at least 90
degrees expected into the middle of next week, along with a heat
index of at least 100 degrees on Monday and Tuesday, this meets the
criteria for an excessive heat warning for the urban corridor from
trenton to philly to wilmington. Will issue an excessive heat watch
through Wednesday, and depending on how things develop, future
shifts will either convert to a heat advisory or upgrade to an
excessive heat warning.

Onshore flow continues to usher a warm and humid airmass into the
region with surface dewpoints in the upper 60s to low 70s and highs
in the 80s to near 90. Surface based CAPE values are quite high,
ranging from 2500-3000 j kg north and west of the fall line to 3000-
3500 j kg south towards delmarva. With that weak shortwave energy
passing through this region this evening, showers and thunderstorms
have fired up across portions of eastern pennsylvania and are moving
into far western portions of the forecast area. Most of the high-res
guidance is indicating little in the way of thunderstorm
development, so will carry likely pops early for the western zones,
and otherwise chance slight chance. Pwats are over 1.5 inches, and
close to 1.75 inches in some areas. In addition, effective shear
ranges from 35-40 kt. Some locally heavy rain and gusty winds are
possible in the strongest of the storms.

With loss of diurnal heating, most activity tapers off fairly
quickly after sunset.

Quite warm and humid overnight with fog developing once again. Winds
take on a more southerly component, and dewpoints will rise towards
the mid 70s overnight.

The remnants of a decaying MCS are over the southern great lakes and
moving into the ohio valley. This should take a track north of the
local area, but there is the potential for showers and thunderstorms
from this system during the overnight hours, especially for northern
zones. Will carry chance pops for the northern zones for the late
night hours to cover this potential.

Short term 6 am Sunday morning through 6 pm Sunday
With a bermuda high in place, and winds shifting to more of a south-
southwest flow, the heat and humidity make a return to the region on
Sunday. Any lingering showers and thunderstorms will taper off and
move out of the region in the morning. Dewpoints climb into the mid
70s through the morning, and then there may be some mixing in the
afternoon to knock those dewpoints down a couple of degrees in the
afternoon. With highs in the upper 80s to lo 90s, the heat index
will at least approach 100 for portions of DELMARVA and the urban
corridor.

Another decaying mcs, along with some mid-level shortwave energy,
with pass north of the region in the afternoon. Another round of
showers and thunderstorms are possible, mainly for the northern
zones.

Long term Sunday night through Saturday
Overview...

an unsettled pattern looks to take hold for much of the long term
period as multiple disturbances pass through a hot and humid air
mass along the northwest periphery of the bermuda high and the
subtropical ridge. Not expecting any washouts over the next several
days, but it looks to be a favorable pattern for a steady dose of
opportunities for convection. Hot temperatures will also be a story
for the first half of the coming week as southwesterly flow will
draw warm and humid air into the region. The heat will peak on
Monday and Tuesday but it will remain warm and humid into at least
Wednesday. A strong cold front is likely to move through towards
Thursday, which should usher in a cooler and much drier air mass
towards the end of the week and potentially into next weekend.

Dailies...

Sunday night-Monday night... There may be some lingering showers or
storms early Sunday night, but they should tend to diminish with
time. Otherwise, it should be a warm and muggy overnight,
potentially with some fog and low cloud concerns as well. A
continued southwesterly flow around the periphery of the offshore
high pressure will lead to additional WAA on Monday, and
temperatures will jump a few degrees from Sunday. Widespread low 90s
are likely with some mid 90s possible in the urban corridor. With
humidity also remaining elevated, heat index values will likely
exceed 100, and either a heat advisory or excessive heat warning
will be needed for the urban corridor depending on how exactly the
numbers evolve in comparison with criteria. Agree with previous
forecaster that Monday looks like it might actually be fairly quiet
for precipitation, at least for most of the day and in most of the
area. Low pressure will be tracking far to our northwest over
ontario, but will drag a weak frontal boundary into our vicinity
late in the day. This could lead to a few late afternoon or evening
showers and storms especially in northern and western areas. This
activity could continue into the first half of what should be a warm
and muggy overnight, but again, expecting coverage to be fairly
limited.

Tuesday-Wednesday night... Chances for convection increase during
the midweek period. A shortwave, which may be convectively enhanced,
approaches on Tuesday. The frontal boundary from Monday, while weak
and losing definition, will also likely stall overhead. With the
shortwave approaching, this should help kick off scattered showers
and storms Tuesday afternoon and evening. Shear does not look very
impressive, but instability should be fairly strong so some strong
to severe storms are possible. Locally heavy rain may also be a
concern given the weak wind fields. Guidance also indicates
potential for convection to continue well into the night on Tuesday.

Wednesday, a cold front will be starting to approach but will remain
to our west. However, a pre-frontal trough will likely serve as a
trigger for another round of convection on Wednesday. Wind fields,
while not extreme, are stronger on Wednesday. Thus the severe
weather risk may be greater that day. However, it is possible cloud
cover may be more widespread Wednesday, which could limit
instability, so it is too early to be confident on severe weather.

Hot weather also continues into midweek with Tuesday looking similar
to Monday and with Wednesday perhaps slightly cooler due to the
additional cloud cover but still warm and humid. Similar to Monday,
Tuesday's conditions will necessitate the conversion of the
excessive heat watch to either a warning or a heat advisory. With
humid air remaining in place, the overnights will continue to be
warm and muggy as well with little relief from the daytime heat.

Thursday... A more robust trough will be swinging into the great
lakes by Wednesday night into Thursday. Ahead of it, a strong cold
front will push through our region. Timing of the front is a little
unclear, as the latest GFS is considerably faster than the latest ec
(not uncommon). Naturally the frontal passage will provide an
additional opportunity for convection. The extent of any severe
weather threat will likely depend mainly on frontal timing, with the
slower ec solution more likely to produce stronger storms since
daytime heating would be maximized. In any areas where the front
moves through early enough, a drying westerly flow will develop.

Ahead of it, such as over delmarva, it will remain warm and muggy.

Friday-Saturday... If the current expected timing of features holds
up, we should see cooler and drier air for the end of the week as an
upper level trough and surface high move overhead behind the front.

This should yield a couple of very nice days. Expecting the drier
air to probably be short lived as the upcoming pattern looks like it
may repeat itself heading into the following week.

Aviation 22z Saturday through Thursday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Tonight... Scattered shra tsra, mainly for krdg kabe and the i-95
corridor terminals, possible into this evening. Brief sub-vfr
conditions possible if a storm passes over a given terminal. Will
use vcts and tempo groups for those terminals. Low confidence for
shra tsra at kmiv kacy. Otherwise,VFR through this evening, then
MVFR ifr in fog late tonight. Another round of shra tsra possible
late in the overnight hours, mainly for krdg kabe. SE winds less
than 10 kt, becoming lgt vrb tonight.

Sunday... Morning fog dissipates toVFR conditions. South winds 5-10
kt. Scattered shra tsra possible in the afternoon and evening once
again.

Outlook...

Sunday night... Scattered showers and thunderstorms with associated
restrictions are possible for the first half of Sunday night. Patchy
fog may develop later Sunday night. Light southerly winds expected.

Monday-Monday night... Any lingering fog or low clouds should
dissipate early Monday, with conditions turningVFR towards mid-
morning and southwest winds around 5 kt.

Tuesday-Thursday... Prevailing conditions should beVFR, however,
several opportunities will exist for showers and thunderstorms and
associated restrictions. Low clouds and patchy fog also possible
during the overnight periods. Winds will be generally out of the
south or southwest, though may be light and variable on Tuesday and
could turn more westerly by Thursday.

Marine
