Low pressure and associated frontal boundaries track across the
region Friday. High pressure builds over the area for the
weekend. Another area of low pressure crosses the area Tuesday.
Near term /until 6 am Friday morning/
Latest msas has high pressure off the new jersey coast with a
warm front snaking it way across the mts. Kept the evening dry
except over extreme western zones where a few showers are
possible before midnite. High res data shows that overrunning
moisture pushes across the area after midnight ahead of the
leading warm front. Chc pops east to likely over the piedmont
late. Lows mid 40s north, lwr 50s south.
Short term /6 am Friday morning through Sunday/
Will follow the premise that there will be two main areas of
convection Friday. First one comes during the morning hours as
the warm front lifts north across the fa. Mdt to hvy rainfall
will be the threat here and added locally hvy rainfall to the
grids. Expect to see a few hour "lull" in pcpn coverage in the
afternoon ahead of the triple point low progged to track east
but remain north of the fa late. Thinking is that the second
area of convection will be associated with the trailing cold
front as it crosses the region Friday afternoon and evening.
This is where/when the potential for strong to isltd severe
tstms will be but will be highly dependent on the amount of
heating that occurs in the warm sector. NAM is the more
"bullish" model with respect to a severe threat than the gfs.
Spc keeps the entire fa in a marginal risk with the threat being
large hail and damaging winds. Best instability progged across
the southern half of the fa. Went ahead and beefed up the
wording in the hwo for now. Will carry categorical pops all
areas given the amount of both atlantic and gulf of mexico
moisture entrained into the system. Average QPF around one inch.
Highs from the mid 50s-lwr 60s eastern shore, mid 60s-lwr 70s
west of the bay.
Low moves off the nj coast Friday evening. Dry slot behind it
will likely cut off the moisture after midnight. Thus, likely
pops during the evening tapers off to chc after midnight, ending
all areas prior to 12z sat. Lows Friday night in the upr 40s-lwr
Low pressure moves farther offshore Saturday with high pressure
building into the area from the west. This high tracks over the
area Saturday night then moves east Sunday. Upshot will be a dry
and rather mild weekend. Should see a large range in temps
Saturday with the coolest readings along the coast. Highs there
from the upr 50s- lwr 60s ranging to the upr 60s-mid 70s west of
the ches bay. Cooler Saturday night with lows 40-45. Highs
Sunday in the 60s except remaining in the 50s along the coast.
Long term /Sunday night through Thursday/
High pressure slides offshore Sun night/mon as the next low
pressure system deepens over the ARKLATEX region/lower ms
valley. The low is now expected to track across the southeast
states Mon night and into the mid atlantic region on tue...
exiting well east of the DELMARVA coast Tue evening/overnight.
Increasing cloudiness late Sun night into mon. Lows in the 40s
sun night, and highs in the 60s to around 70f south on mon
(upper 50s to lower 60s atlantic beaches). Sfc pressure gradient
tightens substantially late Mon night into Tue ahead of the
approaching cold front. S-w winds could become gusty but this
potential will be highly dependent on where the warm front
actually tracks. Given the swd track of the low with the most
recent 12z model run, do not want to commit to any particular
model solution yet. Overall, widespread rainfall is anticipated
in the Mon night to Tue timeframe. Timing is not favorable for
thunderstorms at this time, therefore limited precip wording to
showers. Warmer temperatures Mon night/tue as the associated
warm front lifts north through the region. Lows Mon night in the
50s. Highs Tue in the lower 70s (mid-upper 60s NRN neck and
md/va eastern shore). No hints of major cooling behind the
departing low pressure system, therefore expect lows in the
upper 40s north to lower 50s south Tue night. Brief/weak high
pressure for Wed with highs generally around 70f (low-mid 60s
Aviation /20z Thursday through Tuesday/
High pressure just off the mid atlantic coast will drift to the
east as low pressure over the middle mississippi valley moves
east through the ohio valley. A mostly overcast sky with
ceilings of around 5 to 7 k ft will prevail during the balance
of the afternoon with east and southeast winds of 6 to 12 knots.
Overnight... Winds turn more southerly and ceilings lower ahead
of an area of rain that will arrive Friday morning. Visibilities
and ceilings will lower to MVFR early Friday morning and to ifr
at times late in the morning.
Outlook... Low pressure will continue to move east through
northern parts of the mid atlantic states and eventually off the
new jersey coast by early Saturday morning. A trailing cold
front will cross the forecast area late Friday associated with
scattered thunderstorms. Precipitation and low conditions will
move off the coast early Saturday morning with high pressure
rebuilding back over the area for the weekend. There will be a
chance for showers western portions of the area by late Monday
as the next system develops over the mississippi valley.
Widespread precipitation and degraded aviation conditions are
likely Monday night and Tuesday.
High pressure continues to slide ewd off the DELMARVA coast
tonight as an approaching low pressure system tracks over the
great lakes states. E winds AOB 15kt become more SE overnight.
Seas 3-4ft in persistent onshore swell. Waves 2-3ft. The sfc
pressure gradient tightens rapidly Fri morning as a warm front
lifts north across the area ahead of the approaching cold front,
which is expected to cross the waters Fri evening. Se-s wind
speeds are expected to increase to low-end SCA (15-25kt) fri
morning... Becoming sw-w and decreasing AOB 15kt Fri evening with
the cold frontal passage. Seas also build to 5ft Fri morning and
could reach up to 6ft NRN coastal waters Fri aftn... Primarily
due to continued onshore swell. Elevated seas around 5ft are
expected to linger through Fri night for NRN coastal waters
before subsiding below 5ft by sunrise Sat morning. Waves on ches
bay will average 4-5ft in areas south of new point comfort and
3ft north. SCA flags have been hoisted for all waters beginning
at 700am Fri morning except the upper james river where winds
will stay AOB 15kt.
Weak high pressure returns to the region sat/sun with northerly
winds AOB 15kt Sat and AOB 10kt sun. Seas average 2-4ft. However
once the exiting low moves far enough ewd, seas could re-build
to 5ft far NRN coastal waters Sat aftn into Sun as a result of
northerly swell. Waves generally 1-2ft. High pressure slides
offshore Sun night/mon as the next low pressure system deepens
over the ARKLATEX region/lower ms valley. The low is now
expected to track across the southeast states Mon night and into
the mid atlantic region on tue... Exiting well east of the
delmarva coast Tue evening/overnight. Next best chance for sca
conditions will be Mon night into Tue morning. Winds generally
se-s 15-25kt, seas building to 4-6ft, and waves averaging 3ft.
