area forecast discussion
national weather service wakefield va
657 am edt Sat aug 24 2019

Synopsis
A cold front will stall along the carolina coast over the weekend.

High pressure will build in from the north behind the front
through today. Low pressure is expected to develop along the
front early next week.

Near term through tonight
As of 400 am edt Saturday...

as of this morning, a cold front is located just south of the
forecast area with north to northeast winds in its wake. High
pressure builds in from the north through today, bringing drier
air to portions of the region (particularly north of i-64). Do
expect at least partly sunny skies across the northern half of
the forecast area by this afternoon, higher cloud cover will
persist further south. Northeast flow along with plentiful low
level moisture will allow for the continued chances of showers,
especially across far SE va and NE nc closer to the boundary.

Much cooler today compared to the past couple of days, highs
will generally range from the mid to upper 70s, potentially
cooler in areas where rain showers persist.

Short term Sunday through Monday
As of 400 am edt Saturday...

by Sunday morning, the surface high looks like it will push the
moisture far enough south to limit the chances for any showers
to mainly NE nc and far SE va with drying of the mid and upper
level expected to continue through the day on Sunday suppressing
the pcpn farther south through the day. However, the low level
moisture should remain in place with strong easterly flow
through about 850 mb. That may be enough to hold clouds in place
and could limit the day time heating. For now have gone close
to 80s most areas, but if those lower clouds do hold together
could see readings more in the mid 70s toward the southern va
piedmont.

The forecast for Sunday night into Monday could change rapidly
over the next few days depending on the potential development of
a tropical system of the SE us coast. The models are struggling
with the development and location of the system with the 00z
gfs quicker to develop the system and move it northward off the
carolinas by Monday afternoon while the 00z ECMWF continues to
be slower and farther to the SE off the coast with much less
impact to the region. Very minor changes to pops with this
update, maintained low chance pops with the moisture overrunning
the wedging high. Again will need to monitor the potential
tropical development along the SE us coast this weekend.

Long term Monday night through Friday
As of 300 pm edt Friday...

the early part of the extended forecast will depend much upon any
development and potential track of the tropical disturbance
currently off the fl coast. Latest NHC outlook suggests that
this system will stay well off the local coast. Despite that,
given the proximity to the tropical system and the potential for
some tropical type showers to move across the area, and some
reinforcing moisture lift from weak upper disturbances moving
across the mid atlc and NE states in the w-sw flow aloft, will
maintain low chance pops Mon night through thu. However, if the
tropical system stays further offshore it is conceivable that
much of the middle of next week will be dry other than perhaps
some widely scattered afternoon evening storms. Otherwise, by
Friday the GFS and ECMWF both show drying across the area as a
ridge axis builds in from the west. As such, have kept Friday
dry.

Temps on Tuesday will trend slightly below normal due to the
extensive cloudiness (although it will be muggy), but then rise to
near normal for wed-fri.

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

scattered very light rain showers will be possible through the
morning for the southern two-thirds of the region, little to no
impacts are expected with these. Ceilings have becomeVFR at all
taf sites minus ecg, and are expected to stayVFR through the
afternoon and overnight. Ceilings at ecg are expected to become
vfr by 18z. N to NE winds will range around 10 to 15 knots
along the immediate coast and diminish to less than 10 knots
further inland. Additional showers redevelop across
far southeastern portions of the region this evening and
overnight.

Outlook: low pressure developing along a stalled front and
high pressure building in from the north will keep an easterly
flow across the region through early next week. Easterly flow
will allow for ample moisture, chances for additional showers,
and the potential for sub-vfr ceilings (especially at eastern
taf locations) into early next week.

Marine
As of 630 am edt Saturday...

a NE wind has increased to 15-20kt across the bay and mouth of
the james early this morning. SCA flags have been added through
10 am as high-res guidance has the wind diminishing to 10-15kt
later this morning into the aftn.

Previous discussion...

a cold front is pushing swd through nc early this morning
as high pressure builds across the great lakes. The wind has shifted
to nne behind the front 10-15kt, and this has resulted in 3-4ft seas
in the ocean and 2-3ft waves in the bay. The high will build across
upstate ny and into NRN new england today as the front settles off
the carolina coast. Therefore, the wind will shift to NE and remain
10-15kt. The high strengthens and remains nearly stationary tonight.

Meanwhile, an inverted trough begins to develop along the old
frontal boundary and the pressure gradient will tighten along the
mid-atlantic coast. A NE wind should increase to 15-25kt tonight
into Sunday, with seas building to 4-5ft N and 5-6ft S later tonight
into Sunday. SCA flags remain in effect for the bay and lower james,
and have been added for the ocean (primarily for seas) and the
currituck sound. The wind will remain NE Sunday night into Monday as
tropical low pressure organizes off the carolina coast. Sca
conditions for seas (potentially building to 5-8ft) will likely
linger into early next week as the flow remains onshore and with low
pressure over the ocean. By Tuesday night and Wednesday the wind
should become N and then SW as the low pulls well offshore. This
should allow seas to subside.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
