The episode as NWS LWX wrote it up.
A nearly stationary boundary oriented from north to south set up over the area. Showers and thunderstorms developed along the boundary. Storm motion was also north to south, which allowed for storms to train over the same locations, resulting in isolated instances of flooding.

Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
940 PM EDT Wed Jun 22 2022
.SYNOPSIS...
A cold front will push through from the northwest tonight into
Thursday, then stall out south of the region through the end of the
week. High pressure returns briefly for the weekend before another
cold front approaches by early next week. High pressure returns for
the middle of next week.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Low level airmass has stabilized across much of the area with
lessening instability, and the severe weather threat has ended.
However, north to south oriented boundaries are still stalled
across the area and a cold front is approaching from the
northwest. Very high moisture content remains (precipitable
water over 2 inches) along with elevated instability, so
expect convection, some of which could train, to persist over
the next few hours. A Flood Watch for the potential of flash
flooding remains in effect. Do think rates should be gradually
decreasing, but may need to extend the watch for a few hours for
parts of the area. Showers and perhaps a few thunderstorms could
linger near the I-95 corridor well into the night and Thursday
morning as low level convergence will remain across this area.
Low clouds and perhaps some fog will develop as the night wears
on as well thanks to the abundant low level moisture. Overnight
lows will large be in the 60s.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
Some patchy fog is possible early Thursday morning in our
southwestern zones due to trapped moisture and light winds. As
for the remainder of Thursday, the main wind flow will be out of
the north along with lingering shower activity in the wake of the
frontal passage early in the day. A few showers and storms may
linger over the eastern areas during the afternoon, but expect
to be drying out by the evening. High temperatures on Thursday
are expected to be cooler due to a northwesterly flow.
Increasing heights on Friday with high pressure building in to
the region before moving offshore Friday night. This will
result in dry weather and increased temperatures. Dry weather
continues Friday night with winds lightening up. Dew points
remain in the upper 50s to low 60s with lows in the low 60s.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
High pressure is expected to persist over the Mid-Atlantic through
Saturday. Mid-level height falls are expected Sunday through Monday
as an upper-level trough extending from Hudson Bay to the Mid-
Atlantic States swings through. The associated surface frontal zone
is expected to cross the area by Monday evening with a pre-frontal
trough axis shown by guidance as early as Sunday evening. The timing
of the front remains somewhat uncertain; a later frontal timing will
increase the threat for showers and perhaps a few strong to severe
thunderstorms with heavy rain Monday. Otherwise, more isolated
thunderstorms are possible mainly west of the Blue Ridge Mountains
around peak heating over the weekend, especially on Sunday.
Strong high pressure for late June standards builds into the area
during the middle of next week bringing a nice refreshing trend.
&&
.AVIATION /02Z THURSDAY THROUGH MONDAY/...
With multiple slow moving fronts across the area, widespread
showers and embedded thunderstorms will continue, though thunder
coverage should decrease as the night wears on. Heavy rain will
be possible at times. Precipitation should gradually increase
in intensity, although showers may linger near the I-95 corridor
for much of the night. On top of all this, MVFR to IFR ceilings
in a marine layer are overspreading the area and will persist
through a good part of Thursday. Winds will largely be light and
out of the east.
Some lingering showers and perhaps a few afternoon rumbles of
thunder could bring some brief lower VSBYs to the main 3
terminals of BWI, IAD, and DCA, as well as MTN on Thursday.
Coverage of any impactful rain will be pretty low.
VFR conditions and light winds return by Thursday evening and
continue through Friday night.
Mainly VFR this weekend w/ S/SE flow. Tstm chc increases by late
Sun.
&&
.MARINE...
Showers and thunderstorms will continue through much of the
night, but the threat for gusty thunderstorm winds have
diminished. Easterly winds have enhanced behind a coastal front,
however, and therefore have issued a Small Craft Advisory for
all waters except the middle/upper Potomac through 10 AM
Thursday.
The rest of Thursday should be quieter. A few gusts to near 15
kts are possible over the waters. A few showers and perhaps a
rumble of thunder are possible during the afternoon over the
waters, but only a few gusts perhaps up to 25 knots expected at
worst in those.
Winds remain fairly light Thursday evening through Friday with
dry conditions expected. No marine hazards anticipated at this
time.
Gusty S/SE winds are possible this weekend as high pressure moves
offshore and a cold front approaches from the west.
&&
.TIDES/COASTAL FLOODING...
Tide levels likely remain elevated in onshore flow through late in
the week. This may result in near minor flooding at times along
vulnerable shoreline.
