Synopsis
A strong cold front crosses the area today as low pressure
tracks across north carolina. High pressure builds in from the
north Wednesday through Friday.

Near term through tonight
As of 655 am edt Tuesday...

latest upper air analysis shows a deep upper trough centered
from ontario to the ERN midwest slowly moving eastward. At the
sfc, low pressure was centered from nj to long island, with the
trailing cold front extending SW to fci-fvx-nw nc. A second sfc
low pressure center has started to develop over ERN tn WRN nc.

Closer to our area, there are some pre-frontal showers across
the ERN cwa, with an area of steadier rain behind the front in
the va piedmont mountains. Temperatures have fallen into the
upper 60s across the NW piedmont, but are still in the mid 70s-
around 80f over SE va NE nc. No significant wx expected in the
from now through midday noon with just a steady light-moderate
rain across northern western zones and ongoing (scattered)
showers across the se.

While skies will remain mostly cloudy (even ahead of the front)
through much of the day today, there will be enough Sun for
temperatures to quickly rise into the 80s across SE va NE nc.

Highs will mainly be in the 70s (w temps dropping into the 60s
at times) over the NRN two-thirds of the cwa. As the front moves
into SE va by this aftn, numerous showers tstms will quickly
develop along it, with mainly light-moderate rain continuing
from central va to the nrn CWA border. The front is expected to
slow down as it crosses SE va (and eventually NE nc) later this
aftn-this evening in response to a developing area of sfc low
pressure tracking ene across nc during the day today. With
precipitable water values AOA 2 inches and the flow aloft nearly
parallel to the slow-moving frontal boundary, am still concerned
about the potential for training storms. Storms will initially
be discrete but are expected to quickly evolve into a line be
late aftn. The href continues to forecast 30-50% probs of >3" 3
hours (with the focus across SE va). Given relatively dry
antecedent conditions across far SE va, will hold off on
issuing an flash flood watch, as the ground (especially over
rural swampy areas) should be able to handle a decent amount of
rainfall. However, there is a relatively high chc of at least
some localized flash flooding in urban populated areas from
hampton roads to norfolk va beach. The potential for flash
flooding will need to be monitored and a short fused flash flood
watch may need to be issued. Qpfs through tonight range from
2-3" across the SE to 0.5-1.5" N of i-64.

There is also a marginal-slight risk of severe wx across se
va NE nc this aftn. Wind fields aloft increase as the upper
trough digs across the eastern half of the country, allowing a
40-50kt 500mb jet to move over the area. This wind field
combined with any afternoon heating will be enough for a few
strong to severe storms. However, the big limiting factor will
be the weak mid level lapse rates owing to the very moist
atmosphere. The best chc of severe wx will likely occur when the
cells are discrete initially (mainly from 17-21z). Tstms
eventually move into NE nc by evening as the front slowly moves
se and low pressure moves toward the NE nc coast. The front
finally clears the CWA by 00-03z Wed as the low moves offshore.

Showers end from NW to SE tonight as the low slowly pulls away
from the coast. Lows tonight mainly in the 60s (w upper 50s
possible across the NW piedmont and low 70s in coastal SE va ne
nc).

Short term Wednesday through Thursday night
As of 355 am edt Tuesday...

high pressure slowly builds in from the north on wed, before
becoming centered over the area late thu. One cannot rule out
scattered showers and isolated storms right through Wednesday
across coastal zones as the upper trough axis approaches the
area on wed. Kept pops mainly in the slight chc range, as the
latest guidance shows that any appreciable deep-layer
moisture will remain to our south and east. It will remain dry
across inland zones on Wed (and dry in all areas from Wed night
through Thu night).

Temps will be below average on Wed thu, with highs mainly in the
82-85f range (and lower humidity). Lows Wed Thu night mainly in
the low-mid 60s inland (while remaining around 70f along the
immediate coast of SE va NE nc.

Long term Friday through Monday
As of 345 pm edt Monday...

quiet and quite pleasant weather expected for the extended with
high pressure in control through the week and weekend. Will keep
with a dry forecast thu-Monday. Temps will slowly trend upwards
starting out in the mid 80s Thursday, then gradually rising to
the lower 90s Sun mon. Very seasonable for late july.

Aviation 12z Tuesday through Saturday
As of 700 am edt Tuesday...

scattered shras are ongoing throughout the area this morning and cigs
are starting to fall into the MVFR range. A cold front
(currently just S of ric) continues to cross the CWA from NW to
se through late evening. CIGS likely fall to ifr at ric by
15-16z, while remainingVFR MVFR elsewhere. Expect tstms to
develop along the front during the midday-aftn (likely over
se va at first), with mainly shras and a slight chc of thunder
n of the front. The front slows down later this aftn-this
evening as it approaches NE nc, with tstms expected to continue
along it. Tstms move SE of the terminals by 00-03z wed, but
scattered-numerous shras will continue through 06-09z near the
coast and across the se. Pcpn likely ends at ric by 00-03z wed.

Cigs drop to MVFR at all sites by aftn (w prevailing ifr cigs
likely continuing at ric). Prevailing ifr CIGS are possible at
sby phf orf by early evening, but confidence is too low to
include in the tafs. Vsbys in shras will mainly be 3-6sm, but
ifr lifr vsbys are likely in any tstm. Have added tempo groups
of tsra at phf orf ecg in the 18-00z timeframe due to high
confidence. Conditions improve from nw-se tonight-wed am.VFR
expected from wed-fri.

Marine
As of 220 am edt Tuesday...

a cold front will be slow to push across the local waters
through late today. SW winds 15-25 kt starting out... Gradually
lowering (to 10-20 kt) while becoming wnw then N post cold
front today. Scas to remain in place through early this morning
for all areas except the upper james... York... And rappahannock
rivers. The SCA will ling through the rest of the morning over
the NRN 2 3 of the ocean waters due to seas remaining 4-5 ft.

Sfc hi pres builds in behind the front from late Wed into fri
keeping NE winds 5-15 kt. With NE winds 5-15 knots. An increase
in seas to 2-4 ft, especially near and S of the mouth of the
ches bay... Will accompany the period of NE winds into the late
week period.
