area forecast discussion
national weather service wakefield va
143 am edt Wed aug 21 2019

Synopsis
A trough of low pressure will persist across the area through
Thursday. A strong cold front moves across the area Thursday
night, then stalls across north carolina Friday. High pressure
builds into the area for the weekend.

Near term until 6 am this morning
As of 940 pm edt Tuesday...

sct (pulse type) tstms have been the rule since late this
afternoon W a couple of stms containing strong severe downburst
winds. There are lingering shras stms attm... Mainly NE of a
orf-ric-ofp line. Hanging onto pops 30-40% pops for those areas
to parts of the lower md ERN shore through about 04-06z 21
before waning. Locally heavy rain will be the main threat now w
the loss of heating. A weak S W will be approaching from
wrn central nc late tonight which may result in isold shras
across far SRN va interior NE nc. Lows mainly 70-75f.

Short term 6 am this morning through Thursday night
As of 335 pm edt Tuesday...

the above mentioned short wave will slowly move across the
forecast area on Wednesday. This disturbance combined with the
lee trough will allow for another day of widely scattered pop up
thunderstorms. Best activity may be in the east just ahead of
the short wave, but one could not rule out storms closer to the
lee trough in the piedmont either. As such, will go with chance
pops everywhere once again, but focus the highest pops to the
east and to the west during the afternoon.

A cold front approaches the area later Thu and slowly moves
through the area through Friday. Will need to maintain chance
pops Thu aftn through Thu night. Indications that the front
nearly stalls across the area on Friday, which may allow for
some training of storms Friday afternoon especially across the
southern half of the area. As such, will go with likely pops
across the south on Friday.

Temperatures will remain seasonable with low-mid 90s for highs
and upper 60s-mid 70s for lows. Temps do drop back into the mid
80s on Friday with the frontal passage and increased cloudiness.

Long term Friday through Tuesday
As of 335 pm edt Tuesday...

model consensus is slightly slower with the frontal passage than it
was yesterday, as the latest 12z 20 GFS has come into better
agreement with the ECMWF gem. The GFS is forecasting the front to be
invof SRN va NE nc by early Sat am. The latest ECMWF gem both have
the front positioned slightly further n. As a result, expect
showers tstms to continue across the CWA (mainly S of i-64) for much
of Fri night with the front nearby. The cold front very slowly moves
southward next weekend as high pressure over the great lakes slowly
builds toward the region. Shower TSTM chances continue this weekend
over S SW portions of the CWA as ridging aloft sets up off the sc ga
coast and our region GOES under moist wsw-sw flow aloft while sfc
ridging builds into the area. Have a mainly dry weekend forecast for
nrn zones W 30-40% pops for SRN va NE nc. Continued chances for
mainly aftn-evening showers tstms early next week as weak troughing
tries to re-establish itself from the great lakes to the deep south
and deep layer moisture continues to stream into the region from the
sw.

Highs mainly in the low-mid 80s through the weekend with lows in the
60s (except for some low 70s in coastal SE va NE nc). Slightly
warmer by next Tuesday with highs mainly in the mid 80s.&&

Aviation 06z Wednesday through Sunday
As of 140 am edt Wednesday...

sct convection conts to pop up east of i95 erly this morning,
but not affecting any TAF site attm. Latest data shows this
activity dissipates over the next few hrs, so decided to keep
thunder out of any TAF site.

Vfr conditions should prevail through the forecast period.

The exception will be for some ptchy br arnd sunrise in areas
that received rain last nite and for yet anther day of late
aftrn eve convection that fires up along the lee trof. Weak low
pressure across nc may also fire up sct shwrs across sern taf
sites after sunrise. SW winds 10-15 kts this aftrn.

Outlook...

more of the same Thursday as addntl late day eve convection
dvlps along the lee trof. A cold front slowly moves across the
local area thurs nite then stalls across nc fri. Expct sct to
numerous shras and tstms are anticipated W (and lingering
behind into sat) that cold frontal passage.

Marine
As of 300 pm edt Tuesday...

no headlines through at least today and most of Wednesday. Early
this afternoon obs continue to show generally a S SW flow of 5-10
kts. Waves are 1-2 ft and seas 2-3 ft. Wednesday night winds and
seas will increase ahead of an approaching cold front. SW winds gust
15-20 kts, and seas build 3-5 ft. SCA may be needed late Wednesday
into Thursday. Latest model guidance continues to show the front
crossing through the area early on Friday, resulting in a N NW flow
behind the front. Winds will then shift to onshore flow this
weekend.
