AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
213 PM EDT Mon Jul 3 2023
.SYNOPSIS...
Typical summer weather is expected through midweek. Shower and
thunderstorm chances will be highest this afternoon and evening,
then drop off slightly for Tuesday and Wednesday.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 120 PM EDT Monday...
Latest surface analysis reveals 1020+mb high pressure east of
Bermuda this afternoon. To the west, weak ~1010MB surface low
pressure continues to slide east across the eastern Great
lakes/interior northeast. The low is dragging a rather weak trailing
cold front across the Ohio Valley and mid-south. A subtle
surface/lee trough west of RIC metro into the piedmont. Aloft,
dampening/flattening upper ridge remains offshore of the east
coast, with a positively-tilted upper trough centered over
Atlantic Canada and extending back into the Ohio Valley.
Mid-level clouds continue to spill across (mainly) northern and
central parts of the region, holding temps down slightly. Across the
southeast, mainly clear/sunny sky and high dewpoint values are
combining for very warm heat index values already in the 100-105
range per 17z Obs.
Mesoanalysis showing plenty of instability building in the very
warm, moist airmass over the region. 17z Mesoanalysis showing 1500-
2500 J/Kg of MLCAPE already in place across far SSE portions of the
area, with improved deep layer shear (30-40 KT, highest north,
though co-located with highest CIN thus far today) relative to
the past few days. Starting to see a bit of a CU field pop out
west as sky clears out, and as remnant convective inhibition
gets worked through, expect the same out over the coastal plain
and eventually to the NNW of RIC.
PoPs increase to chc/SCT after 3-4 pm across the area,
maximizing in the 40-50% range for scattered storms across the
area after 5pm through 10 pm. Areal coverage should be higher
today vs yesterday with more of a tangible convective trigger
present with the trough and approaching front. SPC has
introduced an Enhanced Risk over our region today, with damaging
winds as the main threat, though locally heavy rain and
frequent lightning are likely in any thunderstorms. An isolated
tornado cannot be ruled out, though the hodographs and LCLs
above 1000m are not favorable.
Lastly, a Heat Advisory remains in effect for this afternoon
along and southeast of a Lawrenceville to Wakefield and
Gloucester line, including much of south central/southeast
(Hampton Roads) VA and all of our NE NC counties (except the
northern NC outer banks).
Convection slowly wanes tonight, though a few lingering showers and
storms could persist into the late night hours across the eastern
shore and eastern VA. Lows late tonight will be in the low-mid 70s.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
As of 210 PM EDT Monday...
Additional convection is likely on Tuesday the 4th, mainly
across the south and southeast along the stalled boundary. The
severe risk will be lower, as lower shear likely portends a more
disorganized, sub-severe storm mode. However, given plenty of
heating/instability, isolated to widely scattered convection
across the area remains reasonable. Locally heavy rain is the
main threat, but gusty winds are possible with a few of the
more organized storms. Remaining very warm and humid with highs
back into the low 90s. Heat indices slightly lower on average
but still around 100 for much of the region, but a few counties
across the coast of the Albemarle could again approach 105 deg
heat indices tomorrow. Evening activities on Tuesday will be
highly dependent on decaying convection, especially across the
southeast, but northern sections should be slowly drying out
through the night. Lows still in the 70s.
Flow aloft becomes quasi-zonal with time on Wed, with the upper
ridge dampening ahead of next upper trough dropping out of the
Canadian Prairies. Surface heating and the remnants of the
weakening front/coastal trough will should be sufficient for
afternoon/evening thunderstorms. Highest PoPs are south of I-64
(30-50%) and slight chance north. Highs will again be in the low
90s, lows in the 70s.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/...
As of 210 PM EDT Monday...
The amplifying upper trough eventually drops across the upper
midwest Thu-Fri, sending a cold front toward the region going
into next weekend. This will bring renewed chances for showers
and t-storms. However, the increased cloud cover will also bring
a modest cool down into the upcoming weekend. NBM continues to
be a bit too hot with rain chances so have capped at chance
range for now.
Temps slowly step down toward normal through the period. Quite
warm to start out Thu/Fri with highs in the low 90s, with heat
indices around 100 each day. Temperatures behind the front drop
back toward climate normal numbers into the 80s to around 90
over the weekend. Lows will be around 70 each night.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 120 PM EDT Monday...
Mainly VFR conditions across area terminals this morning. Expecting
terminals to remain dry through mid-afternoon, with rain chances
ramping up after 20-21z (4-5pm) through this evening, as a weak
front crosses the area. S/SW winds will average ~10kt, with
gusts to around 20kt especially along the coast. Expect a
somewhat higher coverage of storms (relative to yesterday) late
this aftn and into the evening. Brief reductions to MVFR are
possible for any terminal that encounters these storms, with gusty
winds, heavy rain, and frequent lightning .
Outlook: Generally looks like a lower coverage of aftn/evening
storms for Tue/4th of July), except perhaps across the far SE.
Current pattern favors continued daily afternoon/evening
isolated to scattered thunderstorms each day Wed-Fri, along
with the potential for early morning low stratus and patchy fog
(especially in areas that receive rain).
&&
.MARINE...
As of 145 PM EDT Monday...
A weakening sfc trough approaches the local waters tonight...then
lingers near the coast Tue. WSW winds generally AOB 10 kt becoming
SSW this evening...10-15 kt and occasionally gusty. Seas 2-4
ft...waves mainly 1-2 ft. The trough pushes S of the local
waters Wed...then lingers INVOF the Carolina coast Thu/Fri. The
wind will briefly shift to NNW 5-10kt early Wed...then will
primarily be ESE at 10 kt or less through the remainder of the
week. Seas subside to 2-3 ft Tue...then will generally be ~2 ft
through the end of the week...w/ waves on the Bay ~1 ft.
&&
.TIDES/COASTAL FLOODING...
As of 140 PM EDT Monday...
Tidal anomalies are averaging around 0.6-0.8ft above normal in
the middle Bay early this morning, and including the lower tidal
Potomac, primarily due to a modest and persistent southerly wind.
This combined with a period of higher astronomical high tides
due to the lunar cycle (full moon) pushed water levels near minor
flood thresholds along the Bay- side of the MD Eastern Shore
with the previous high tide. Similar conditions should persist
for the higher astronomical high tide later tonight/early Tue
morning resulting in elevated water levels to near minor flood
thresholds (particularly at Bishops Head).
The forecast for Independence Day in a low risk S and a
moderate risk N. Visit our beach page at www.weather.gov/beach/akq
for the latest rip current and beach forecasts.
