AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
409 PM EDT Thu Aug 4 2022
.SYNOPSIS...
Hot and humid conditions prevail today, with isolated to
scattered showers and thunderstorms into this evening. A
somewhat unsettled pattern with higher precip chances is
expected Friday into the weekend. A cold front may bring cooler
conditions by the middle of next week.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 350 PM EDT Thursday...
The latest WX analysis indicates sfc high pressure centered
(well) offshore of the SE US coast with a weak sfc trough
in place to the lee of the Appalachians. Aloft, a strong upper
low is centered over Hudson Bay, with a trough extending S to
the OH/mid-MS Valley. Shortwave energy moving through the SW
flow aloft in combination with steep low level lapse rates has
led to scattered tstms over much of the piedmont and into the
coastal plain of VA this aftn. Deep layer shear is quite weak,
but some isolated to widely scattered strong to severe storms
are expected through sunset (for wet microbursts/locally
damaging winds). PoPs will be 30-50% through sunset (highest
inland), diminishing to 20-30% later this evening, then mainly
dry overnight (will keep a 15% PoP over the ern shore after
midnight).
The Heat Advisory remains in effect through 6-8pm for much of
the ern 1/2 of the area for heat indices of 105F+ though
locally cooler temperatures will develop over the next few hrs
where showers/tstms move in. Remaining warm and muggy with lows
in the mid to upper 70s SE to 70-75F elsewhere (coolest NW).
For Fri, generally dry and partly-mostly sunny in the morning,
with PoPs increasing by aftn. Highest PWATs reside across the NW
portion of the CWA and forcing will be best in this area as
well. Will have PoPs 50-60% across the NW, tapered to 20-30% far
SE. WPC has the far NW portion of the CWA in a slight risk
day2,ERO with a marginal risk into much of metro RIC. The storms
will be fairly slow moving given rather weak flow aloft so at
least localized flooding can be expected Fri aftn/evening.
Continued very humid Fri, but highs will avg a few degrees
cooler than today so will hold off on any Heat Advisories,
though it may be close to 105F over the SE.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 400 PM EDT Thursday...
Models are in agreement keeping the cold front N of the region
for the weekend. However, with the parent trough still well off
to the northwest in the Ohio Valley, there's little appreciable
forcing to kick the front into the area. As such, the front
will slowly weaken as it approaches the area, and will wash out
north of the mid- Atlantic over the upcoming weekend. With that
said, general weak troughiness aloft does look to remain through
at least Sat, which should at least be conducive for
maintaining at least isolated to scattered showers and storms
Saturday, with PoPs lowering a bit on Sunday.
More scattered to isolated coverage on Saturday. Best chances
remain over the NW CWA, though aforementioned instability and
moist airmass should allow for convection to fire just about
anywhere across the area along remnant outflows and last
vestiges of the piedmont trough out west. Remaining seasonably
very warm and humid with highs in the upper 80s to low 90s.
Generally dry along the coast with 20-30% PoPs inland Sun aftn.
Highs mainly in the lower 90s and continued humid.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 350 PM EDT Thursday...
Bermuda ridge dominates through Tues. A pattern changing cold front
moves through Wed into Thurs with a possible reinforcing cold front
Fri into Sat. This will result in a trough centered over the
Northeast to strengthen from Wed into early next week with cooler
temps expected over the region. Diurnal afternoon/evening showers
and storms will be possible Mon and Tues with the best chance for
showers/storms Wed (continuing into Thurs for SE portions of the FA)
with the cold front. Highs in the lower to mid 90s Mon and Tues,
lower to mid 80s NW to the lower 90s SE Wed, and 80s everywhere
Thurs. Lows in the lower 70s W to mid 70s E Sun through Tues nights
and mid 60s NW to lower 70s SE Wed and Thurs nights.
&&
.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
As of 200 PM EDT Thursday...
Scattered tstms into this evening (highest chc at RIC), with
brief flight restrictions mainly in VSBYs in heavy rain along
with gusty winds. Mainly VFR overnight.
Outlook...There is a decent chance (30-60%) of aftn/evening
showers/tstms Friday, with a gradual lowering w/ respect to
coverage Sat. More typical late day showers and storm chances
for the latter half of the weekend into early next week.
Primarily VFR outside of showers/tstms Friday through Monday and
potentially some brief early morning stratus over the weekend.
ASOS observations remain missing at ORF. A trouble ticket has
been opened but timeframe for a resolution to the problem is
not yet known.
&&
.MARINE...
As of 215 PM EDT Thursday...
Winds have remained rather light today generally south to
southwest at 5 to 10 kt. Winds may still increase few knots late
afternoon and evening, but trend has been lower. Main weather
maker is the bermuda high offshore which will remain in control
for the next several days resulting in very little change in the
overall conditions.
Southwest winds increase some off the surface overnight and with
the warm Bay this could keep winds around 10 kt (maybe even 15
kt) overnight. Tomorrow appears to be repeat of today with
persistent southerly flow with the offshore high dominating.
Isolated showers and storms are possible Friday with a little
more coverage later in the afternoon and evening over the
middle and upper Bay. A weak southerly surge of wind on the Bay
is again possible late Friday night, but still no more than 15
kt or so. This pattern remains in place through the weekend both
Sat and Sun. The pres gradient does appear to tighten some late
Sunday which could result in slightly stronger southwest winds,
but still sub SCA.
