.SYNOPSIS...
High pressure will be in control the rest of today before
shifting offshore on Monday. A warm front will pass through the
region on Monday as well, before a cold front gradually tracks
through the area on Wednesday. This front will then stall over
the Mid-Atlantic region through the end of the week into next
weekend, causing a period of unsettled weather.
&&
.NEAR TERM /THROUGH MONDAY/...
Broad and elongated high pressure extends from the Canadian
Maritimes southward into the Mid-Atlantic region. Little change
in position is expected tonight, but by Monday, the axis of the
high will move off the coast.
In the meantime...for the rest of this afternoon, skies have become
mostly sunny across much of the region, however stubborn cloudiness
lingers over the Delmarva and western portions of the area. Clouds
should continue to dissipate through the rest of the day though, so
expect mostly clear skies heading into tonight. Aside for a few low
clouds overnight, skies should remain mostly to partly clear with
light winds. Also, a few instances of patchy fog are possible in
more sheltered areas. Another cool night is expected, with lows in
the mid 40s to mid 50s as another ideal radiational cooling set-up
is on the table.
On Monday, as the high shifts offshore, surface flow will transition
to southerly in the afternoon. This will set-up the beginning of a
warm air advection regime through the middle of the week, where high
temperatures are expected to top out in the upper 70s to around 80
degrees under partly cloudy skies.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
The first part of the upcoming week will feature temperatures mostly
above normal. Weak upper ridging across the Middle Atlantic Mon
night/Tue gradually flattens by early Wednesday. A cold front drops
across the area Tue but then washes out by Wed. This front and the
increasing moisture across the area will lead to scattered showers
Tue afternoon throgh Wed.  Pops will be higher for the NW areas Tue
with chance most areas and likely for the southern Poconos. A couple
of tstms are possible too. Chances will be less on Tue for Delmarva
and south NJ where pops will be below slight chance. For Tue
night/Wed the pops are mostly chance for the entire area, but higher
for the North/West counties (50%) and closer to 30% for S/E regions.
High temps Tue will be the warmest of the period with low/mid 80s
many areas and 70s near the shore. Readings Wed will still be above
normal, but 4 or 5 degrees cooler than Tue. Lows will favor the 60s
both Mon night and Tue night.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
More unsettled weather for the long term too. After Wednesday, the
operational models are showing H5 height falls and a cutoff low
forming across the Midwest. Once this low forms, it`ll move to the
East coast and linger into the weekend. This will keep showery
weather for much of the time, and perhaps provide some needed rain
to our area. Since the details will change numerous times before the
time, we`ll just use the NBM pops/wx for now. Mostly chance pops
thru the period but some likely pops for friday for the western
areas. Temperature thru the period will mostly be near normal for
late September.
&&
.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Rest of Today...Primarily VFR at all terminals although a few patchy
areas of MVFR CIGs cannot be ruled out at times. East-southeast
winds around 5-10 kt. Localized gusts up to 20 kt possible at KACY.
High confidence.
Tonight...VFR with a few low clouds developing around 06Z. Winds
light and variable, favoring an east-northeast direction less than 5
kt. High confidence.
Monday...VFR expected. East winds in the morning, becoming south
winds around 5-10 kt in the afternoon. High confidence.
Outlook...
Mon night... Generally VFR. Can`t rule out some patchy fog overnight.
Tue thru Fri... VFR most of the time. Scattered showers and a few
tstms (Tue) could bring lower CIGs/VSBYs however.
&&
.MARINE...
A Small Craft Advisory is in effect until 2 PM on Monday for the
coastal waters extending from Manasquan Inlet to Fenwick Island
mainly due to seas around 5 feet. Elsewhere, no marine headlines are
in effect.
East-northeast winds around 10-20 kt this afternoon will diminish to
around 5-10 kt tonight. Northeast winds will continue into Monday
morning, before shifting to east-southeast around 5-10 kt in the
afternoon. Seas of 3-5 feet expected through Monday. Fair weather.
Outlook...
Not many changes from the previous forecast. High pressure across
the waters Monday night and early Tuesday weakens. It is then
replaced by a series of weak disturbances/fronts which will affect
the waters late into the upcoming week and next Sat. We`ll have
scattered showers each day and perhaps a few tstms Tue. Conditions
will overall remain below SCA levels, but seas may approach 5ft at
times Tue and Thu.
Rip Currents...
On Monday, east winds turn to the southeast, generally less than
10 mph with breaking waves of 2 to 3 feet. Easterly swells
associated with offshore Hurricane Gabriel will build to 3 to 4
feet with a 10 to 11 second period. As a result, there is a HIGH
risk for the development of dangerous and life threatening rip
currents for the Jersey Shore and Delaware Beaches.
Winds turn more southerly on Tuesday at 10 to 15 mph. Southeast
swells continue with a 11 to 13 second period. There will likely
be a HIGH risk for the development of dangerous and life
threatening rip currents for the Jersey Shore and Delaware
Beaches on Tuesday as well.
