What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Baltimore/Washington wrote its last area forecast discussion before this small craft advisory went out at Sep 6, 9:06 PM EDT, 4 hours 12 minutes earlier.

Area forecast discussion, Sep 6, 9:06 PM EDT, 4 hours 12 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Baltimore MD/Washington DC
906 PM EDT Mon Sep 6 2021

.SYNOPSIS...
High pressure will build in and remain over the area into
Tuesday. A cold front will progress through the area during the
middle of the week with high pressure building in by late in the
work week and into the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...

Weak high pressure will build over the area overnight. Clear
skies and cool temperatures in the 50s are expected west of
I-95 and low 60s east. Some patchy fog is possible over interior
valleys west of I-81.

Previous afd...

High pressure continues to build in from the west which will lead
to a cooler night ahead. Decent radiational cooling should take
place as winds lighten and skies remain mostly clear. While low 60s
will be commonplace inside I-95, mid/upper 50s can be expected
elsewhere. Some patchy fog may develop in this environment, mainly
along I-81 and back into the Alleghenies.

With high pressure gradually shifting offshore on Tuesday, return
flow ensues bringing humidity levels back up a bit. Sunshine
will remain plentiful as a shortwave ridge tracks overhead. The
steady warm advection through the day will bolster temperatures
back into the mid 80s which is about 3 to 5 degrees above early
September normals.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
A much milder night will be on tap for the region with the
persistence of south to southwesterly flow. Mid to upper 60s are
likely for most spots east of the Blue Ridge and Catoctin with near
70 degree readings in the warmer DC and Baltimore city centers.

Wednesday ultimately brings the best convective chances to the
region as a strengthening upper trough approaches from the west.
Currently near the Alberta/Saskatchewan border, this system will
dive southeastward during the next couple of days toward the
Mid-Atlantic region. The core of lower heights remains over the
Great Lakes with thhis mentioned feature sweeping through
underneath by late Wednesday. The lack of collocation of the
forcing from the trough and diurnally forced instability leaves
some uncertainty around convective coverage and intensity.
However, the 12Z NAM nest and a couple global solutions show a
lee trough forming during the afternoon hours. Vertical motions
associated with this or any mesoscale boundary may prove
instrumental to some shower/thunderstorm activity. Surface
conditions will be more ripe for instability based on
temperatures in the mid/upper 80s and dew points in the upper
60s. Will continue to monitor the convective threats in the
upcoming forecast cycles.

As the height falls track through late Wednesday into the overnight,
a band of showers are forecast to progress eastward ahead of a cold
front. Much of this activity should wind down before daybreak the
following day. Temperatures cool in the wake of this boundary with
overnight readings in the lows 50s along the Allegheny Front.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
The aforementioned cold front will continue moving through the
eastern part of the CWA Thursday morning. Therefore, have continued
to maintain a slight chance for showers early on Thursday mainly
southeast of I-95. High pressure will then build in through the end
of the week. The next front/disturbance arrives later next weekend,
but confidence is low rain making it this far south at this time.

Temperatures Thursday into Friday will be slightly below average.
Given the dry airmass associated with the region of Canadian high
pressure, temperatures Thursday night could be the coldest across
the region since June. Currently have widespread 50s west of I-95
except for in the mountains where temps could fall into 40s, with
60s expected near the metros/bay. The colder elevated valleys of
Garrett, Grant, Pendleton, and Highland counties could make a run
into the lower 30s, resulting in patchy frost Thursday night.
Similar conditions, though a degree or two milder, are possible
Friday night.

Temperatures moderate a few degrees over the weekend as heights rise
and high pressure moves offshore.

&&

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected through at least the first half of
Wednesday. Dry conditions will occur during that period of time
with west-northwesterly winds shifting to southerly on Tuesday.
Any patchy fog formation should occur well west of the area
terminals. For Wednesday afternoon and into the night, showers
and thunderstorms are possible as a cold front approaches from
the west. This may lead to some restrictions with confidence low
in exact timing and placement.

Aside from a few morning showers that could result in MFVR condtions
at the terminals along I-95 Thursday morning, VFR condtions should
dominate Thursday afternoon into Friday. The winds behind the front
Thursday into Friday will generally be northwest up to 10 knots.

&&

.MARINE...
By Tuesday, winds shift to southerly which leads to some
channeling of the winds by the evening hours and into the
overnight. As such, a Small Craft Advisory has been issued for
much of the Chesapeake Bay as well as lower portions of the
tidal Potomac. On Wednesday afternoon/evening, scattered showers
and thunderstorms may lead to periods of hazardous conditions
over the marine waters.

There could be a period of SCA winds early Thursday behind the cold
front as northerly channeling sets up over the Chesapeake Bay. SCA
conditions are not likely to later Thursday into Friday as high
pressure builds.

&&

.TIDES/COASTAL FLOODING...
Southerly flow will resume Tue with rising anomalies by Tuesday
night. This might result in minor flooding at sensitive sites
by Wednesday morning.
