AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
312 PM EDT Mon Jul 8 2024
.SYNOPSIS...
Unsettled weather continues through the week with daily chances for
scattered afternoon and evening showers and storms. More widespread
showers and thunderstorms are likely Thursday through Friday. Very
warm and humid conditions continue through much of the week as well.
The highest heat indices are expected on Tuesday and Wednesday.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
As of 310 PM EDT Monday...
Key Message:
- Scattered showers and storms are possible through this
evening.
Upper level ridging remains to our south this afternoon while an
upper trough lingers across the Midwest. Sfc high pressure
remains anchored well offshore while TC Beryl continues to track
N through Texas. Temps are mainly in the upper 80s-lower 90s
with heat indices in the 90s-around 100F. Scattered showers and
tstms have developed (and as of now they are mainly from FVX
east to around Williamsburg). The uncapped environment will
allow scattered showers/storms to continue through early to mid
evening before diurnal weakening occurs, with the highest
coverage expected to be across central portions of the FA.
Given the very humid (PWATs ~2.00") airmass in place and slow
storm motions, locally heavy rainfall will continue to be
possible (have already seen a couple of the storms drop 2-2.5"
of rain in an hour). The threat for severe wx is quite low,
although localized 40-50 mph gusts are possible with the
strongest storms. Diurnal weakening quickly occurs this evening
with dry wx expected overnight. Humid with forecast lows in the
mid 70s for most.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/...
As of 310 PM EDT Monday...
Key Messages:
- Hot and humid Tuesday and Wednesday with widespread heat
indices of 105-109F.
- Isolated to widely scattered showers and storms are expected
Tuesday and Wednesday afternoon/evening.
Tuesday will be the hottest day of the week as upper heights rise
slightly as the offshore ridge tries to build toward the area a bit.
Widespread mid 90s are expected inland, with low-mid 90s closer to
the coast, and upper 80s at the MD beaches. Not expecting more than
isolated to widely scattered aftn/evening tstms, and this activity
should generally stay west of I-95 (if it makes it into the area).
Given dew points in the mid 70s (locally upper 70s near the coast),
max heat indices will rise to 105-109F, with a few 110F readings
possible. As a result, have issued a Heat Advisory for nearly all
the area from 11 AM-8 PM Tue.
The remnants of TC Beryl get picked up by an upper level trough over
the upper Midwest Tue, and are progged to track into the eastern
Great Lakes on Wed. While the remnants of Beryl remain NW of the
local area, the trailing cold front from the system weakens as it
moves towards the local area Wed, but will very likely still be just
to our west by Wed night. Still hot and humid on Wed, but it looks
to be a degree or two "cooler" as upper heights fall a bit.
Nevertheless, Heat Advisories will likely be needed again for a
decent portion of the area on Wed and lows will only fall to the mid-
upper 70s Tue night. Also, there is once again the potential for
isolated-scattered aftn/evening tstms (highest PoPs west of I-95).
Isolated showers/tstms may linger through Wed night, although
coverage will decrease after midnight. Quite humid with lows once
again in the mid-upper 70s.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/...
As of 310 PM EDT Monday...
Key Messages:
- Widespread showers and a few thunderstorms are expected
Thursday into Friday. Locally heavy rainfall is possible.
- Hot and humid weather returns over the weekend with daily
chances for mainly afternoon and evening showers and storms.
Unsettled wx is expected late this week into the weekend weak S-SW
flow aloft continues across the area in between broader troughing to
the NW and ridging offshore. The remnants of Beryl lift NE into
Canada by Thu with direct rainfall from the system remaining to the
NW of the local area. However, the trailing cold front from the
system will likely stall just to our west on Thursday before slowly
washing out by Friday. At the same time, a shortwave approaches from
the south Thu/Thu night. This feature (along with a weak sfc low) is
then progged to track across the area from Fri-Fri night. It still
looks like PWs will be in the 2.0-2.5" range as this feature slowly
tracks across the area.
As a result, scattered to numerous showers/storms are expected Thu
afternoon (50-60% PoPs) through much of Fri/Fri evening (70% PoPs)
before potentially tapering off by late Friday night as the
shortwave exits the area. Locally heavy rainfall appears likely and
the models/ensembles continue to show the potential for areal
average rainfall amounts of 1-2". Of course, localized totals of 3"+
will be possible. WPC has a Marginal Risk for excessive rainfall on
Thu, with a Slight Risk on Friday. A more typical summertime pattern
returns this weekend into early next week with isolated-scattered
diurnally driven convection possible each day.
Highs in the lower 90s Thu (w/ potentially a few 105F heat index
readings near the coast). With the clouds and rain, highs won't be
higher than the 80s on Fri (and it may stay in the mid-upper 70s in
spots). Highs will be near average on Sat before potentially warming
to above average again by Sun/Mon.
&&
.AVIATION /19Z MONDAY THROUGH SATURDAY/...
As of 145 PM EDT Monday...
VFR conditions prevail early this aftn w/ SCT-BKN cumulus but isolated
to scattered tstms have begun to develop INVOF the terminals.
The convection will remain disorganized but will persist
through early-mid evening before weakening. Have VCTS at all of
the terminals through 00z and will amend as needed based on
radar trends. LIFR VSBYs are possible with any storms. VFR
tonight with mainly high clouds.
Unsettled weather continues through the week with daily chances
for showers/storms (mainly during the afternoon/evening
timeframe). The greatest chance for reduces VSBYs/CIGs is Thu-
Fri.
&&
.MARINE...
As of 315 AM EDT Monday...
Key messages:
- Marine Dense Fog Advisory in effect through 7 AM this morning for
ocean zones from Fenwick to Parramore Island for VSBYs less than 1
NM.
- Generally benign, sub-SCA conditions are expected through Tuesday.
- SCA conditions are possible Wednesday afternoon through Thursday
due to increasing southerly winds.
Early this morning, a weak front is located over the local waters
with winds out of the SW ranging from 5 to 10 knots. Seas are
running around 2 feet and waves in the Chesapeake Bay are running
around 1 foot.
A weak front will remain near the waters through tomorrow as it
gradually dissipates over the area. Winds will generally remain out
of the S to SSE and continue to run around 10 knots. Brief increases
in wind speeds to around 10 to 15 knots will be possible both this
afternoon and Tuesday afternoon due to afternoon sea breezes. Seas
will average 2 to 3 feet and waves in the bay 1 to 2 feet through
this timeframe.
Southerly winds increase Wednesday afternoon into Wednesday evening
ahead of another approaching cold front from the northwest. Local
wind probs are maximized Wednesday evening through Wednesday night,
showing a decent potential for gusts of 20 to 25 knots over the
ocean and Chesapeake Bay. In addition, seas will increase to 4 to 5
feet and waves in the bay increase to 2 to 3 feet Wednesday night.
SCAs will likely be needed for at least the ocean and bay starting
Wednesday afternoon. Southerly winds continue to gust around 20 to
25 knots through the day Thursday, before gradually diminishing
Thursday night. Sub-SCA conditions then likely return late this week
into this weekend.
