What forecasters said that day
The local office's own words before this high surf advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Newport/Morehead City, NC wrote its last area forecast discussion before this high surf advisory went out at Aug 20, 1:43 PM EDT, 2 hours 3 minutes earlier.
Area forecast discussion, Aug 20, 1:43 PM EDT, 2 hours 3 minutes before
Area Forecast Discussion
National Weather Service Newport/Morehead City NC
143 PM EDT Fri Aug 20 2021
.SYNOPSIS...
High pressure will continue offshore with weak troughing nearby
into the weekend. Tropical Cyclone Henri is to pass offshore
tonight through Saturday, shifting the surface trough axis near
the coast Sunday through much of next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 955 AM Fri...Weak boundary evident in temp and instability
fields this morning oriented roughly along Highway 17. On the
east side, SPC mesoanalysis shows SBCAPEs well north of 3000
J/kg and a few cells have already fired over the Albemarle
Peninsula. Main concern this afternoon remains the potential for
locally torrential rainfall with latest RAP soundings pointing
to PWATs reaching up to 2 1/3" this afternoon and CAPES
3500-4000 J/kg. Prior forecast captures this threat well and no
changes were made beyond adjusting to observations.
Prev discussion...As of 415 AM Fri...An upper trough over the
ctrl Appalachians will dig s and e today over the Mid Atlantic.
A few lingering debris clouds from earlier convection in the
Piedmont and Coastal Plains is moving through E NC this AM.
A busy day of convection expected today, as extremely moist atms
with PW's around 2.15" per 06Z KMHX sounding expected to inc
even more this afternoon as moisture advection inc with
approaching trough. This will set the stage for sct to
widespread thundershowers breaking out be late morning just
inland from the coast, expanding inland through the afternoon
hours. With little shear expected, no big severe threat in play,
but the very high PW's/mix ratios aoa 17.5 g/kg will produce
high rainfall rates. Threat for localized flooding is in place
across the region today, and have added heavy rain wording to
grids.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
As of 420 AM Fri...Thundershowers will wane through the early
evening hours, and eventually end by around midnight. Should
debris clouds scour out, a decent fog set up will take hold, esp
in areas that receive copious rainfall today. Have added
mention of fog, but wouldn't be surprised to see some dense fog
develop late. Low temps in the 70-75 range most areas, coolest
interior.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
As of 330 AM Fri...Troughing over the area may bring unsettled
weather Saturday as Henri passes well off the coast. Coastal
areas remain unsettled through much of next week, while inland
areas return to a more seasonal pattern starting Sunday.
Saturday...An Omega Block-esque setup will develop aloft over
the weekend, with ridging over the Mississippi Valley and North
Atlantic, and troughing over the eastern US. As a result, the
center of Tropical Storm Henri, which is currently SW of Bermuda
and expected to become a hurricane later today, will pass
several hundred miles east of the Outer Banks Saturday as
southerly a steering current accelerates it toward New England.
The rainfall and wind associated with the core of Henri will
remain east of the area, and there is increasing confidence
that our area will be in the periphery subsidence region of
Henri to start the day Saturday. This will limit us to a few
storms possible mainly along the sea breeze south of New Bern
early in the afternoon, with showers and storms possibly
spreading toward NE NC as Henri moves off the Mid- Atlantic
coast later in the afternoon. Scattered clouds and weak NW flow
through the day will keep highs around to a couple degrees below
normal.
Visit weather.gov/mhx/tropical for the latest National Hurricane
Center advisory information for Henri.
Sunday through late week...Closed upper low over the Mid-
Atlantic coast as the the surface trough axis in the wake of
Henri slides over ENC, where it will remain into late week. By
mid-week, the upper low is absorbed into the background flow
over New England and a general weakness persists overhead.
A fairly persistent forecast through the period, with the trough
axis linger nearby keeping week flow locally and much stronger
low level moisture advection expected to remain offshore.
Isolated to scattered shower activity could be more persistent
along the coast, while a more seasonable/diurnal precip pattern
is expected inland. Temps generally near to a few degrees above
normal through the period.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
SHORT TERM /through 18Z Saturday/...
As of 140 PM Fri...Quickly evolving situation early this
afternoon with a mixed of VFR and MVFR conditions courtesy of a
2-2.5kft cu deck. Showers and thunderstorms quickly evolving
along a subtle boundary draped from roughly KNBT northeast to
KMQI, and expect coverage to expand further inland through the
afternoon. Environment is favorable for torrential rainfall
which could result in brief but severe visibility restrictions
at impacted terminals.
Coverage wanes after 00-01z although some lingering showers are
possible overnight. With expected rainfall and freshly saturated
soils, low stratus appears to be a high probability. Light winds
suggest stratus could lower through the morning resulting in
lower visibilities by early morning, particularly at inland
terminals.
LONG TERM /Saturday through Tuesday/...
As of 345 AM Fri...Some MVFR ceilings could linger Saturday as
TC Henri passes well off the coast, but VFR generally expected
to prevail during the day and thereafter, with typically light
winds. Isolated to scattered showers and storms are possible
early afternoon into early next week, bringing the potential for
brief, localized flight restrictions. Overnight/early morning
fog and/or low stratus will also be possible.
&&
.MARINE...
SHORT TERM /Through Tonight/...
As of 420 AM Fri...Winds remain light swrly 5-15 kt this
morning, and will remain that way today. Trough axis will move
through the waters tonight, with winds becoming n to ne
overnight, though remaining on the light side.
Long period swell from TC Henri will continue to slowly build,
with 4-6 ft seas this morning for the ctrl waters and 3-5 ft
southern and nrn waters. Seas will cont to build through late
afternoon and into tonight, with 5-8 ft seas all waters by later
this evening and overnight tonight with periodicity around
10-12 seconds.
LONG TERM /Saturday through Tuesday/...
As of 4 AM Fri...Guidance continues to come into better
agreement with current TS Henri strengthening to a hurricane as
it passes several hundred miles east of Cape Hatteras Saturday.
This track is expected to be far enough offshore to limit much
increase in the wind field locally, with swell peaking Saturday
morning. N to NW light to moderate winds Saturday morning trend
SW by Saturday afternoon, where they will remain through much of
next week. Seas peak at 6-9 ft Saturday morning before steadily
falling through Saturday night, especially south of Cape
Hatteras where some sheltering from the increasingly NE swell
direction will occur. SCA end times are based on swell dropping
below 6 ft later Saturday, with the caveat that changes to the
track and wind field forecast of Henri will ultimately determine
how quickly conditions improve.
&&
.TIDES/COASTAL FLOODING...
As of 4 AM Fri...TC Henri is expected pass offshore as a
Hurricane on Saturday. Dangerous surf conditions and elevated
rip current risk will continue into early next week. A high surf
advisory may be needed Saturday, when the swell is expected to
peak. Additionally, elevated astronomical tides and the
increased swell could combine to bring minor beach erosion and
the potential for overwash for portions of beach with very
vulnerable dune structures with the early evening high tide
cycles Sat and Sun.
&&
