Area Forecast Discussion
National Weather Service Wakefield VA
350 PM EDT Fri May 25 2018

Dry weather is expected through tonight under the influence of
high pressure off the mid-Atlantic coast. Low pressure over the
Gulf of Mexico will gradually bring a return of moisture through
the upcoming holiday weekend, mainly in the form of afternoon
and evening showers and thunderstorms.


As of 330 PM EDT Friday...

High pressure has shifted a bit further offshore this afternoon
allowing a return of SSW flow over the local area and warmer
temps. Other than scattered CU in parts of the area this
afternoon, the weather is otherwise quiet with all shower
activity relegated to the Carolinas and the mountains of SW VA.
Little change is expected in the weather tonight with the high
offshore and light SSW winds in place. Mainly clear with lows in
the 60s to around 70. Higher dew pts and SW flow should mostly
preclude fog formation early Saturday morning. However, it
cannot be completely ruled out for locations such as


As of 330 PM EDT Friday...

Weak upper ridging aloft and southerly low-level flow will be
our predominate weather pattern through Memorial Day. This will
result in a continued increase in humidity locally through
Sunday, due to sustained southerly flow from the GOMEX, and a
mainly diurnal chance of showers and thunderstorms both Saturday
and Sunday. By Monday there are indications that a little
deeper feed of sub-tropical moisture will make a run at
central/eastern NC and perhaps far southern portions of VA.
While locally heavy rain will be possible with the strongest
tstms Sat/Sun (PWs 1.75-2.00"), the best opportunity for
widespread moderate/heavy downpours and potential flooding
should hold off until Monday for the aforementioned areas as a
more pronounced area of sub-tropical moisture (PWs increasing
to 2.0-2.3") arrives. As far as PoPs go, will carry high chc to
likely (50-60%) along/west of a line from EMV-XSA-CGE Sat aftn,
lowering to slight chc (~20%) for coastal NE NC. Similar PoPs
Sunday but with highest PoPs oriented a bit more N/NE. High
chc/likely PoPs (50-65%) along/north of a line from FVX-FYJ-WAL,
lowering to slight chc (~20%) over the northern OBX. By Monday,
will generally have chc PoPs everywhere (30-50%), but likely
PoPs (55-65%) along/south of VA Hwy 58.

Temps will remain warm Sat/Sun with highs generally in the
mid/upr 80s, except upr 70s to low 80s immediate coast. A bit
cooler Monday with increased cloud cover and pcpn chances. Highs
in the mid 70s to low 80s. Lows remaining in the 60s to low 70s.


As of 330 PM EDT Friday...

This period to be governed by the moisture and remnant low track of
Sub-tropical Storm Alberto. After stalling across the Gulf States
Mon, the system is progged to drift slowly ne into the TN valley
Tue/Wed with the remnant low pushing ne along or just east of the
Applach mts Thu/Fri.

Kept low chc pops (20-40%) across the region Mon nite thru Tues nite
then increased to high chc pops (40-50%) Wed thru Fri. Highs Tues
mid-upr 80s, low-mid 80s Wed/Thu/Fri. Lows mid 60s-lwr 70s.


As of 200 PM EDT Friday...

VFR conditions anticipated through the 18Z TAF period on light
S-SW winds. Patchy fog (MVFR VSBY?) is possible at KPHF/KECG
early Saturday morning, but confidence is not high enough to
include in either TAF just yet.

OUTLOOK...Expect moisture to increase for the upcoming holiday
weekend with scattered showers/t-storms possible each
afternoon/evening from Sat-Mon. Periodic flight restrictions
will be possible in/around tstms.


As of 330 PM EDT Friday...

No flags as SW winds around the Bermuda high dominate through the
holiday weekend. Expect some south channeling at times across
the Ches Bay, otw winds aob 15 kts. Seas 2-3 ft with 1-2 ft

Flow becomes more SE by mid week in advance of Alberto`s remnant
low, the SW behind the lows departure. Speeds below SCA levels.


As of 330 PM EDT Friday...

A flood warning remains in effect for the Nottoway River at
Sebrell. The river level should drop below minor flood stage
this evening or tonight. See FLSAKQ for more details.


As of 330 PM EDT Friday...

South channeling up the Ches Bay will likely have levels
topping out just below minor flooding at Bishops Head. Thus,
went ahead and issued a coastal flood statement for this
evening`s high tide there.


As of 330 PM EDT Friday...
