Synopsis
A cold front extended from low pressure in southwestern quebec
to the middle mississippi river valley this afternoon. The
boundary will progress slowly to the southeast. It is forecast
to move into our region on Thursday night before drifting to our
south on Friday. High pressure is expected to follow for the
weekend. The high should gradually lose its influence over our
weather during the early and middle parts of the new week.

Near term until 6 am Thursday morning
Heat indices for the remainder of the afternoon will be in the
mid 90s to low 100s depending on location. The heat advisory
will be allowed to expire this evening.

Mid-level forcing ascent is spreading across the northern mid-
atlantic and southern new england this afternoon. CAPE values
are also jumping up along side of strengthening shear. A severe
thunderstorm watch in effect until 1000 pm for our forecast
area.

Damaging winds will be the main threat across this area,
although there will be a threat for hail with a fair amount of
cape above the freezing level. Another concern this afternoon
will be the potential for heavy rainfall. Pw values remain
1.75-2.00 inches, so any thunderstorm will be efficient rain
producers.

Things will settle down overnight. The second half of the
overnight looks dry. Temperatures will fall back into the mid
60s to mid 70s depending on location. Some patchy fog is
possible, especially across those locales that see any rain into
the evening hours.

Winds will become less than 10 mph and veer to the west.

Short term 6 am Thursday morning through 6 pm Thursday
As a result of the winds veering to the west (at least 1st half
of day), dewpoints are forecast to be a few degrees lower
tomorrow. And with the lower dewpoints, we are seeing lower
apparent temperatures. The i95 corridor and nj coastal plain
will see apparent temperatures in the mid to upper 90s. The
delmarva will see apparent temperatures around 100. While it
will still be quite hot, these values are below heat advisory
criteria. We will not issue an advisory at this time. Actual air
temperatures are forecast to be around 80 across the poconos,
the upper 80s across berks and the lehigh valley, around 90
across the i95 corridor and coastal plain, and in the mid to
upper 80s near the ocean.

A cold front will be knocking on our doorstep tomorrow morning.

By days end, it should be slowly working across east central pa
and northern nj. A weak low could be riding along the front as
we head into the evening hours. With better forcing tomorrow,
more organized precipitation is possible. Per the SPC convective
outlook, at this time, the area remains under a marginal risk.

Per wpc, the area remains under a marginal risk for excessive
rainfall.

Winds should be 10 mph or less for most tomorrow. While they
are expected to turn more westerly tonight, they should back to
southwest again tomorrow afternoon as the cold front approaches.

Of course, winds could be stronger in and in the vicinity of
storms.

Long term Thursday night through Wednesday
The cold front approaching from the northwest is forecast to
move into our region on Thursday evening. Showers and
thunderstorms ahead of and with the front will produce locally
heavy rain on Thursday evening. Also, there remains a chance for
isolated strong wind gusts and hail.

As the cold front settles in our region on Thursday night,
showers and thunderstorms will linger. However, the potential
for heavy rain, strong wind gusts and hail should diminish from
northwest to southeast as conditions stabilize somewhat.

The front is expected to be across the DELMARVA region on
Friday morning, and it should continue to sink slowly to the
south. We will continue to mention a chance of showers and
thunderstorms for Friday, especially from the philadelphia
metropolitan area southward.

High pressure is expected to be centered in ontario on Friday
night. The high should build east and southeastward over the
weekend, bringing dry weather and cooler temperatures to our
region. A northeast to east flow is forecast to develop by
Sunday. While some of the guidance is showing some spotty light
precipitation for Sunday, it may be a case where the effects of
the trajectory off the ocean are overdone. Perhaps the indicated
moisture will only manifest itself in the form of some cloud
cover.

As the high moves farther away from our region, a trailing
surface ridge to the lee of the appalachians is expected to
narrow on Monday before gradually losing its influence over our
weather on Tuesday and Wednesday. Guidance consensus regarding
the timing and coverage of any precipitation during the early
and middle parts of the new week is lacking. As a result, we
have included only a slight chance for showers and
thunderstorms.
