736 PM EDT Tue Jul 8 2025

.SYNOPSIS...
Hot and humid conditions are expected to continue through this
evening, with Heat Advisories in effect for much of the area.

Flooding continues through this afternoon and evening. The
unsettled pattern is expected for the rest of the week, with
scattered to numerous afternoon through late evening
thunderstorms each day. Near average temperatures are expected
later this week.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
As of 355 PM EDT Tuesday...

Key Messages:

-Severe Thunderstorm has been issued till 9PM this evening for most
of the area.

- Flood watch has been issued for the Northern Neck and MD Eastern
Shore for the increased risk of potential Flash Flooding.

- Heat Advisory stays in effect until 8pm this evening.

Afternoon weather analysis shows a strong ridge located off the E
coast, with a weak upper trough stretching from the Great Lakes down
to the central Mississippi Valley. The 500mb flow aloft is weak out
of the WSW ~20-25kt. Latest surface analysis shows a slow moving
cold front located over southern NY stretching down across PA and
down the Appalachians mountains. Ahead of the cold front a hot and
humid airmass is in place. Temperatures as of 3PM are in the
lower to middle 90s with dew points in the middle 70s. This is
causing Heat Index values to climb between 105 to 109 across the
majority of the area. The Heat Advisory will remain in effect
until 8pm this evening for all except except western Louisa,
Fluvanna, and the MD/NE NC beaches. For tonight, low
temperatures will drop into the lower to middle 70s inland and
upper 70s along the SE coast.

Scattered to  numerous strong to severe thunderstorms are expected
to develop along the high terrain and possible warm sector. As of
3pm satellite imagery is already showing thunderstorms developing
along the Appalachians and Blue Ridge mountains and Piedmont. Ahead
of these thunderstorms, a rich moist and unstable airmass is in
place. Latest meso analysis is showing ML cape values ~2000 J/kg
across the north and 2500-3500 J/kg across the south. In addition to
the ML cape, Dcape values are ~1100 J/kg thanks to the strong low
level lapse rates. Despite the strong instability in place shear
still remains weak.  Effective bulk shear remains between 20 to 25
kt across the south and 25 to 30 kt across the north (closer to the
front). However, these values are just high enough to help produce
strong to severe storms. The main threat for this evening is wind
gusts between 60 to 70mph. The hail threat remains low due to the
lack of shear and mid-level lapse rates. The timing of these storms
have not changed much from the last forecast update. storms likely
enter N/NW portions of the area by 4-5 PM. Scattered to perhaps
numerous storms will likely become outflow dominant as they push to
the SE through at least the NW half of the area before gradually
weakening after midnight. The most likely timing for storms is from
4-8 PM from Louisa-Salisbury, and 7-11 PM from the Richmond Metro to
the VA Peninsulas/Eastern Shore.

In addition to the severe threat, these thunderstorms will be
efficient rain producers given deep warm cloud depths and resultant
PWs ~2". While most areas haven't seen a lot of rain in the past 5-6
days and the storms will be moving (albeit slowly)...a quick 2-4" is
likely in a few spots and this could be enough to cause urban/flash
flooding...especially in metro/poor drainage areas. WPC has extended
the Slight Risk for excessive rainfall for all of VA/MD, with a
Marginal Risk for NC. The 12Z HREF continues to target broad 10%
probability of 3" of rain in 3 hrs this evening across the Northern
Neck and MD Eastern Shore. Given these areas saw rain from the
remnants from Chantal and model guidance continues to highlight the
area a Flood Watch has been issued. Will note, there will be a brief
period where the showers and thunderstorms will stop but due to the
high confidence in additional flash flooding tomorrows the Flood
Watch has been extended till 6z Thursday.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
As of 355 PM EDT Tuesday...

Key Messages:

- Numerous thunderstorms are expected during the afternoon  through
late evening on both Wednesday and Thursday, with   coverage
expected to be fairly widespread over much of the   area.

- Although there is a severe threat both days, the main concern with
the storms will be heavy rain/flooding, given that some areas could
see an additional 1-3+" of rain on consecutive days.

Typical July temperatures are expected for Wednesday and Thursday
with highs in the lower 90s and upper 80s. Dew points will be in the
middle 70s but given slightly cooler temperatures than Tuesday we
will be below Heat Advisory criteria with Heat Index values between
100 and 104 Wednesday and middle 90s Thursday. The main concern for
both these days will be strong to severe storms and Flash Flooding.
On Wednesday the upper trough will move over the area. The upper air
flow will continue to be out of the WSW, however, it will be
slightly stronger with winds ~25 kt across the south and 30 to 35 kt
across the north. Instability values will be around the same as
Tuesday with ML cape values ~3000. Dcape values will be between 750-
1000 J/kg. They are slightly weaker due to the weaker low level
lapse rates. Effective Bulk shear will again be ~25 kt just suitable
enough for strong to severe storms. Some of the high-res model
guidance continues to show these storms developing along the
mountains and moving across the Piedmont. The SPC has upgraded to a
slight risk for damaging winds across the north and west of I-95.
While keeping a marginal for the southeast. The risk for severe
storms continue through Thursday as instability values will continue
to be high and another frontal passage approaches from the west.

The biggest and most concerning threat for tomorrow is the risk for
additional Flash Flooding. Latest model guidance continues to show
PWs climbing upwards of 2-2.2". Recent High-res models continue to
show additional rain totals between 1 to 3" across already saturated
areas. There is also the potential that some of these areas could
see high amounts (4") due to the slow motion and more wide spread
convection. If the same areas that see high rain fall totals on
Tuesday see these higher amounts, this could lead to faster Flash
Flooding. The recent 12z HREF has shown a wide spread  10%
probability of 3" of rain in 3 hrs across the I-95 corridor and
west. It also highlights a 30% probability of 3" of rain in 3 hrs
across the RIC metro area north across the Northern Neck and MD
Eastern Shore. With all of the ingredients, model guidance, and
confidence in the forecast a Flood watch has been issued for I-95
corridor and north. This covers the peninsulas and MD Eastern
Shore. The SE has been left out at this time due to the uncertainty,
but depending on latest trends in the model data maybe added in the
future. The risk for potential flash flooding continues Thursday as
the daily risk of thunderstorms continue in an already saturated and
moisture driven environment.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
As of 355 PM EDT Tuesday...

Key Message:

- Staying seasonably warm and humid through the weekend with mainly
afternoon/evening storm chances persisting.

The seasonable yet unsettled July weather pattern continues through
the end of the week and into the weekend. An upper ridge to the
southeast and decently fast zonal flow aloft will move across the
northern United States and southern Canada. An upper level
disturbance will track over the local area with WSW flow aloft. This
will result in typical diurnal showers and thunderstorms  each day
through the end of the weekend. The good news is the storm coverage
will be less this weekend than it is expected to be on Friday. Exact
details are difficult at this time to pinpoint this far out, the
main concern with any storms will likely be localized flash flooding
given the rain expected from today through Friday and continued weak
flow aloft. Highs each day will be around seasonal averages for this
time of year (upper 80s/around 90F).

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
As of 736 PM EDT Tuesday...

Scattered thunderstorms are developing across the area this evening,
though most of it has steered clear of the terminals so far. This
will likely come to an end of the next few hours as storms become
more widespread. Have included a PROB30 at ORF, as confidence is a
little low to include a TEMPO at this time. TEMPOs are in place at
PHF, RIC, and SBY to account for the convection through later this
evening. There will be a lull overnight in storm activity through
tomorrow afternoon/evening. Though there is high confidence in storm
development tomorrow, the exact timing is a little tougher to nail
down at this time. Have only included a PROB30 at RIC for now, but
degraded flight conditions will likely need to be included at all
terminals as confidence increases in timing. Outside of storms,
winds will range between 5-10 kt from the southwest, though a
few gusts to 15 to 20 kts are not out of the question tomorrow
as daytime heating ramps up and allows for better mixing.
Lastly, guidance is hinting at some patchy fog and MVFR CIGs
potentially developing in the wake of the convection over the
Piedmont late tonight, perhaps inching close to RIC, so have
dropped to 5SM for a few hours.

Outlook: Mainly VFR outside of storms from Wed-Fri. Scattered
to numerous afternoon-late evening tstms are expected each day,
along with some early morning ground fog/stratus.

&&

.MARINE...
As of 355 PM EDT Tuesday...

Key Messages:

- Strong to severe storms possible late this afternoon into this
evening across the northern waters where a Severe Thunderstorm Watch
is in effect.

- Southerly winds will increase late this afternoon into this
evening with a few gusts to 20 kt in the bay and 25 kt over the
ocean.

- Another round of gusty southerly winds expected again on Wed
afternoon/evening, along with possible strong to severe storms.

Showers and thunderstorms will increase in coverage late this
afternoon and into this evening ahead of a cold front well northwest
of the area. Some of the storms could be severe, especially
across the northern waters. Meanwhile, the pressure gradient
will tighten across the area this afternoon into this evening
which will allow for some gusty south winds into this evening.
Guidance is not in great agreement in the winds tonight but the
consensus is around 15 kt over the bay and 15 to 20 kt over the
ocean. Will not issue a SCA but conditions will be a little
choppy especially over the bay. Winds decrease tonight, but
then increase again on Wednesday as another round of showers and
storms impact the waters. Again, some of these could be strong
to severe as they move through. Beyond tomorrow, expect
relatively benign conditions across the waters for the remainder
of the week.

Seas generally 3 to 4 feet late this afternoon into tonight over the
coastal waters, then subsiding to 2 to 3 feet by tomorrow morning.
Seas then building again to 3 to locally 5 feet by Wed evening as
the south winds increase once again. Seas then falling to around 2-3
feet by Thursday and into the weekend. Waves over the bay 2 to 3
feet tonight then falling to 1 to 2 ft Wed AM, before building again
to 2 to 3 ft by tomorrow evening. Waves mostly 2 feet or less Thu
through the end of the week.

The moderate risk of rip currents remain in effect today, with low
rip currents expected Wed and Thu.
