Synopsis
High pressure remains centered just offshore of the southeast
coast today... As a surface cold front approaches the region
from the northwest. The remnants of tropical depression cindy
will cross the region with the cold front on Saturday. The front
then stalls farther south off the carolinas Sunday and Monday.

Near term until 8 pm this evening
Latest analysis reflects surface cold front aligned from the
western great lakes back into the mid-mississippi river valley.

Low pressure... The remnants of TD cindy now noted on early
afternoon vis IR satellite imagery lifting across the mid-south
toward the lower ohio river valley. Regional radar mosaic
indicating some isolated light to moderate showers pushing
across the area at 18z. However, latest mesoanalysis indicating
a capping inversion in place across the area. Question for the
balance of the afternoon is how quickly can we can destabilize
that cap enough to tap into convective potential. Time-lagged
hrrr and conshort blend has done well with convective trends so
far, and have leaned in its direction for the afternoon and
early evening.

Overall, expect mainly dry (albeit very warm and humid)
afternoon across the southern half of the area, with no real
discernible trigger and drier air filtering in from the coastal
carolinas. Therefore, will go no higher than a 20% pop for
isolated shower or t-storm. Farther north, cap should be strong
enough to prevent much more than scattered convection through
00z. Well-advertised low-level jet analyzed over E oh W pa, and
should be far enough north to not have too much of an impact
with convective potential locally. Thus, pops have been tapered
down into 30-40% range over far NW zones (cumberland, va to
tappahannock, va to salisbury, md) for the afternoon. This area
already seeing a nice CU field developing, and cams are at least
a little bit more bullish on convective development up that way.

Otherwise, very warm, breezy and moderately humid this
afternoon with highs in the u80s to low 90s for most inland, low
to mid 80s along the atlantic coastal zones.

Short term 8 pm this evening through Sunday
Rain chances in the short term mainly confined to late tonight
through Saturday night, as the remnants of cindy get absorbed
and essentially merge into a frontal wave, lifting from the
lower ohio valley toward the southern mid-atlantic late tonight
through Saturday afternoon.

Any scattered showers and storms quickly wane this evening with
loss of heating. We then wait until after midnight, as the
surface front which extends from a low in SE canada approaches,
dragging the remnants of TD cindy across the N NW portions of
the local area along with it. The front will supply enough lift
for a narrow area of showers and an isolated thunderstorm late
tonight and early Saturday. Overall trend has been towards a
more progressive solution with the 12z suite of models. After
which, models are in fair agreement with shearing the precip
apart Saturday afternoon. Meanwhile, an upper trough over the
midwest will slowly dig southward and help to slowly, but
steadily, push the front east across the area... Especially as
the bermuda high also retreats to the east. Maintained 40-60%
rain chances over the coastal plain during this period for the
afternoon and evening... And into the overnight hours Sunday
morning, as the front gets hung up across the SE coast into the
carolinas. Warm and muggy yet again with highs generally in the
upper 80s (lower 90s possible far SE va NE nc prior to arrival
of cold front). Dewpoints in the lower 70s.

Cooler, drier air filters in from the northwest behind the
front. Lows Saturday night in the low-mid 60s far nw, upper 60s
inland, lower 70s se. Dewpoints lower 60s NW to lower 70s se.

Overall, a pleasant day anticipated for Sunday. Lingering
spotty convection along the albemarle sound will come to an end
Sunday morning with the rest of the area remaining dry. A much
more comfortable afternoon and evening Sunday, with highs in
the mid 80s (lower 80s beaches), and dewpoints in the upper 50s
nw to mid 60s se. Comfortable sleeping weather Sunday night with
lows in the upper 50s NW to upper 60s se.

Long term Sunday night through Thursday
Cold front pushes offshore Saturday night, stalling along the
coast Sunday. Height falls ahead of a deepening upper level
trough over the great lakes ohio valley Sunday and remnant
moisture along the boundary will result in isolated to scattered
showers and thunderstorms across northeast north carolina Sunday
afternoon. Drying inland. Highs Sunday in the low to mid 80's. A
secondary front pushes into the region Sunday night and Monday.

Have only kept slight chance pops inland Monday given limited
moisture. Highs in the low to mid 80's. Potent shortwave digs
into the ohio valley and central appalachians Monday night into
Tuesday with a stronger cold front pushing through the region
Tuesday. Moisture return along the coast will result in isolated
to scattered showers and thunderstorms across eastern virginia.

Cooler Tuesday with highs in the mid to upper 70's. Dewpoints
mix into the 50's, resulting in pleasant afternoon conditions.

Dry and comfortable conditions forecast again Wednesday as the
trough pushes offshore and heights build over the ohio valley.

Surface high pressure settles over the mid-atlantic. Highs
Wednesday generally in the low 80's. Cool Thursday morning, with
lows in the upper 50's inland to mid 60's near the coast. High
pressure slides offshore Thursday with return flow resulting in
moderating temperatures. Highs in the mid 80's.

Aviation 18z Friday through Wednesday
Generally am anticipatingVFR conditions to prevail this afternoon
and evening. Brief periods of MVFR ceilings may be possible this
afternoon with a sct-bkn 2500 foot cloud deck. High resolution
models continue to hint at a few showers and potentially a rumble of
thunder impacting northern and western portions of the region later
this afternoon. Any showers that do redevelop will be highly
scattered in nature, but may produce periods of MVFR. All
precipitation is expected to taper off after sunset. A cold front
approaches western portions of the region by 08z bringing the next
chance for showers. The highest chance for rain will once again be
confined to northern and western portions of the region. Winds will
continue to be gusty this afternoon, occasionally gusting in excess
of 25 knots. Gusts to around 30 knots will be possible after
midnight as the cold front approaches the region and the gradient
tightens.

Outlook: scattered showers and thunderstorms may redevelop Saturday
afternoon and evening, bringing the potential for sub-vfr
conditions. Any shower activity comes to an end by early Sunday. A
return toVFR conditions is expected Sunday through early next week
as high pressure builds into the region.

Marine
High pressure remains anchored off the southeast coast early
this morning as the remnant low that was formerly cindy is
centered over ar as of 07z. High pressure will prevail off the
southeast coast through Saturday. Meanwhile, the remnant low of
cindy tracks through the tennessee valley today and tonight, and
then across the NRN mid-atlantic Saturday. Additionally, a cold
front will push into the ERN great lakes today into tonight.

This combined with the approach of the remnant low will result
in a tightening pressure gradient and strengthening low-level
jet tonight through midday Saturday. A SW wind will average
10-15kt early today and then increase to 15-25kt across the nrn
bay NRN ocean zones this aftn, followed by a lull early this
evening. Given this, scas north of new point comfort and
parramore island will commence at 17z. A SW wind will then
increase to 15-25kt (gusts up to 30kt possible in the ocean bay)
across the entire marine area later this evening through the
overnight hours and through midday Saturday. Scas for the
remainder of the area begin at 02z Saturday. Seas build to 5-7ft
north of parramore island late tonight into Saturday morning,
with 4-6ft out near 20nm north of CAPE charles, and primarily
3-4ft farther south with an offshore component to the wind.

Waves in the bay build to 3-4ft late tonight into Saturday
morning. SCA conditions end Saturday as the wind diminishes and
seas gradually subside. A cold front pushes across the coast
Saturday night with a wind shift to nw. Sub SCA conditions are
expected due to a lack of caa, another cold front pushes across
the coast Monday night, with high pressure building over the
region through the middle of next week.
