AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
724 PM EDT Sat Aug 7 2021
.SYNOPSIS...
Low pressure tracks across the region through tonight, bringing
locally heavy rain to the region. Weak high pressure returns
Sunday into the middle of next week.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
As of 545 PM EDT Saturday...
Cancelled the Flash Flood Watch for all areas except for
immediately adjacent to the bay/coast...as all of the moderate
to heavy rain is confined to the Lower Ern Shore at this hour.
Remainder of forecast remains on track with minor updates to
PoPs to reflect a drying trend for the wrn two-thirds of the
FA.
Previous Discussion as of 310 PM EDT...
Afternoon wx analysis shows low pressure tracking along a sfc
boundary that is currently bisecting the forecast area, with a well-
defined shortwave trough aloft over the Appalachians. The boundary
is roughly positioned from ASJ-AKQ-WAL. Ample deep-layer moisture is
present over the area with SSW flow aloft, with PWs currently aoa 2"
across much of the area. The heaviest rainfall has generally been
along and just to the northwest of that boundary, with widespread
amounts of 1-3" and localized amounts of 4"+. In addition, locally
enhanced low-level directional shear/SRH INVOF the aforementioned
boundary (across SE VA and NE NC) has resulted in a few rotating
storms. An isolated spin-up tornado can't be completely ruled out
through early evening across far SE VA and NE NC. Any severe threat
will diminish towards sunset. Rain will end from SW to NE from this
evening-tonight as the sfc low tracks across the Lower Ern Shore and
then just offshore by Sunday morning. PoPs diminish to slight
chc/chc in all areas except for the VA Nrn Neck and Lower Ern Shore
by 00z/8 PM...and the steady moderate to heavy rain should end on
the Ern Shore by 06-09z tonight. Have cancelled the Flash Flood
Watch west of I-95...and will let the remainder of the watch run
through 02z/10 PM. No northward expansion planned attm...as rain
rates are not expected to be high enough for flash flooding on the
cool side of the low (but will continue the HWO mention of localized
flooding...given the potential for amounts of 3-4" in several hours).
Although drying aloft moves in from the SW from through tonight,
expect low clouds to linger and persist into tonight/early Sunday
morning. Cannot rule out fog by late tonight as well. Forecast lows
generally range from the 60s to around 70F early Sunday morning.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
As of 310 PM EDT Saturday...
Not a whole lot of change to the forecast from Sun-Tue, as upper
heights rise over the local area by Mon as ridging builds from the
Gulf Coast to SE CONUS and the low currently over the area moves
well to our NE. After some early morning low clouds/fog on Sun,
clearing skies are expected as the shortwave trough exits to the
northeast. It will be mainly dry with a very low chc of an aftn
shower/tstm across mainly areas W of I-95. Highs Sun in the mid to
upper 80s. Some of the models show some showers/tstms continuing
across the area Sun evening so have added 15-20% PoPs across the
interior of VA Sun evening. Lows Sunday night/Monday morning range
from the mid- upper 60s to low 70s. A bit warmer on Monday with
highs in the upper 80s to low 90s. There is a slight chc of an aftn
or evening tstm in areas along and west of I-95, but am expecting
dry wx for a majority of the area. A shortwave trough is progged to
track well to our north on Tuesday while ridging remains in place
across the SE. While the better tstm chances will be to our north on
Tue, have maintained chc PoPs across the NW, tapering to below 15%
SE for diurnal convection. Highs Tue will be in the low 90s in most
areas.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 400 AM EDT Saturday...
A fairly typical summertime pattern will prevail through next
week as upper ridging continues to expand from the Gulf coast to
the SE CONUS. As the upper heights rise, so will the
temperature and humidity, though nothing excessive is expected.
Expect high temperatures to mostly be into the lower 90s by the
early to middle part of next week with lows of 70-75 F expected.
Generally dry conditions are expected during the overnight and
morning through early aftn timeframe, with isolated to
scattered late aftn/early tstms Tuesday through Friday (PoPs avg
around 20% near the coast and 30-40% well inland) as the global
models continue to forecast a couple of shortwave troughs to
track across the Great Lakes, resulting in minor height falls
across the Mid- Atlantic along with humid conditions and a lee
trough developing. A cold front is eventually progged to
approach from the NW by Fri into next weekend. PoPs may
increase a bit higher late in the period.
&&
.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
As of 200 PM EDT Saturday...
Variable conditions continue early this aftn with widespread showers
at RIC/SBY, and a line of showers/tstms moving toward PHF/ORF/ECG.
These showers/tstms (potentially w/ gusts to 25-30kt) will impact
PHF/ORF/ECG between 19-23z. Widespread rain should end at all
terminals except SBY by 00z, and should end at SBY by later
tonight. Still think that low clouds will to be difficult to
scour out so RIC (and possibly SBY) are likely to remain IFR-
LIFR through the evening and overnight into Sunday morning.
ORF/PHF/ECG will be more variable, but will tend to see the
flight restrictions redevelop later in the evening/overnight at
the end of the TAF period.
Outlook...Showers will mostly be done early Sunday morning but
flight restrictions may linger through 12-15Z/Sun. After that, the
rest of Sunday will be mainly dry with VFR conditions expected
(isolated late day/evening tstms possible Sun). Similar conditions
for the rest of the week, VFR with isolated/widely scattered
aftn/evening tstms from Tue-Thu.
&&
.MARINE...
As of 725 PM EDT Saturday...
Weak stationary front splits the local waters N-S this evening.
Weak low pressure will continue to track INVOF that boundary
this evening then continue slowly E overnight. SE across the
N and SW winds over the srn waters this evening with most
speeds 10-15 kt aside from occasional gusts to around 20 kt in
the lower Ches Bay. Winds become W overnight, eventually
becoming NW late. Waves 1-2 ft on the bay and seas 2-3 ft on the
ocean. NW winds (5-15 kt) on the back side of the exiting sfc
low pressure early Sun become VRB or ENE remaining mainly AOB 10
kt. Most waves less than 2...seas 2-3 ft. Bermuda high pressure
will become established for the upcoming week...leading to
generally a prolonged period of weak S winds for the upcoming
week.
Low rip current risk Sun-Mon.
