.SYNOPSIS...
High pressure initially centered over Quebec in the vicinity of
Hudson Bay will continue shifting southeast into the area,
remaining in control through the weekend and into early next
week. A slightly more unsettled pattern may begin to take shape
entering mid-week, with a cold front approaching from the west.
&&
.NEAR TERM /THROUGH TODAY/...
High pressure continues to build into the region, resulting in
a strong pressure gradient as it pushes Hurricanes Humberto and
Imelda out to sea.
Overnight, winds inland will decrease as high pressure shifts
closer from the northwest, keeping skies mostly clear.
Communities along the coast will still see breezy northeast
winds with gusts around 20-25 mph overnight and into early
Thursday morning. The incoming high from the north doesn`t quite
get over us tonight, so the bottom won`t completely fall out
with temperatures overnight. There still will be a crisp chill
in the air though with lows in the mid to upper 40s. In northern
NJ and southern Poconos, it will be even colder, with lows in
the upper 30s/low 40s. Temperatures and winds will both likely
be just a touch too high for frost development.
For Thursday, high pressure will be overspread across the
Northeastern US. Mostly clear skies with cool temperatures once
again with afternoon highs in the mid 60s to around 70.
Northeast winds along the coast will still be gusting to around
20 mph during the afternoon.
&&
.SHORT TERM /TONIGHT THROUGH SATURDAY/...
Mid-level ridging initially centered over portions of the
Tennessee and Ohio Valley regions will shift slowly east into
our area through Saturday. At the surface, high pressure
centered over portions of the Mid-Atlantic and New England will
gradually shift eastward but remain in control.
Skies Thursday night will be partly cloudy across most of the
area, although with onshore flow persisting, skies may be mostly
cloudy in coastal locations. Any clouds should clear out Friday
and skies should remain partly to mostly clear through
Saturday.
It will be a chilly couple of nights with cool days. Lows
Thursday night will range from the low-mid 40s across much of
eastern PA and inland NJ, to near 50 in coastal areas and the
Delmarva. Highs on Friday look to be in the low 70s areawide.
Lows Friday night will be very similar to Thursday night.
Saturday will see a return to above normal temperatures, with
mid-upper 70s prevalent areawide.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Expansive mid-level ridging centered over the area Saturday
night will remain in place through Monday. Monday night and into
Tuesday, the pattern will begin to become more unsettled. A
weak shortwave may pass near or just north of the area on
Tuesday. In addition, a trough centered over portions of Ontario
Tuesday morning will shift eastward through Wednesday. While
the primary trough looks to remain north of the area, height
falls and an enhancement to mid-level flow look likely,
providing at least some synoptic-scale ascent. At the surface,
high pressure initially in control will weaken some and shift
east Tuesday into Wednesday. A cold front may approach from the
west on Wednesday.
It currently appears that at least some chance for rain will
exist across parts of the area both Tuesday and Wednesday. While
the pattern does not appear to support widespread rainfall or
heavy amounts, any chance at some beneficial rainfall is welcome
given the relatively dry pattern that has taken shape across
the region as of late. For now, have low-end chance PoPs (around
30%) areawide both Tuesday night and Wednesday.
Temperatures look to remain above average Saturday night
through Tuesday, with highs generally in the upper 70s to low
80s and lows generally in the mid-upper 50s. Temperatures may be
closer to seasonal norms on Wednesday depending on the extent
of any precipitation or present cloud cover.

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas...
Tonight...VFR. Northeast winds 5-10 kt. High confidence.
Thursday...VFR. East/northeast winds around 10 kt. High
confidence.
Outlook...
Thursday night through Monday...VFR. No significant weather.
&&
.MARINE...
All Gale Warnings along the coastal ocean waters were
downgraded to a Small Craft Advisory. Wind gusts overnight will
remain around 25 kts over the ocean zones, falling to around 20
kts Thursday afternoon. Seas will remain elevated around 7 to 9
feet overnight, only falling to around 5 to 7 feet Thursday
afternoon. For the lower Delaware Bay, the winds have diminished
below Small Craft Advisory levels so the SCA has been
cancelled.
Outlook...
Thursday night through Friday...While winds are expected to
have diminished below SCA criteria by Thursday night, seas will
remain elevated. Seas on Thursday night look to be 5-7 feet.
Seas should diminish at some point Friday to below 5 feet, but
perhaps not until the afternoon or evening hours. Therefore, the
SCA has been extended into Friday afternoon for all ocean
zones.
Friday night through Monday... Winds below 25 kt and seas below
5 feet. No marine headlines anticipated. Fair weather.
Rip Currents...
A high risk of rip currents is likely to continue through the
end of the week. However, the surf program ended on Tuesday,
September 30. No further surf forecasts or rip current
statements will be issued until May 2026.
Always obey posted Beach Flags. If you enter the surf zone,
always have a floatation device with you and swim near a
lifeguard if possible. If caught in a rip current, relax and
float and do not swim against the current. If able, swim
parallel to the shoreline. If unable to escape, face the shore
and call or wave for help.
&&
.TIDES/COASTAL FLOODING...
Minor coastal flooding continues to linger within the back bays
of Sussex County currently, so the Coastal Flood Advisory
remains in effect for minor coastal flooding for Sussex County
until 2 AM.
The tidal gauges at Claiborne and Cambridge have touched minor
flooding with their high tides and have crested, so water levels
will be coming down through the remainder of the night. Impacts
from this minor coastal flooding are expected to be limited
enough to not have an advisory at this time for this high tide
cycle.
&&
.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.
NJ...None.
DE...Coastal Flood Advisory until 2 AM EDT early this morning for
     DEZ003-004.
