PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents. Rip currents are life-
threatening to anyone entering the surf. Swim near a lifeguard.
If caught in a rip current remain calm. Don't fight the current.
Swim in a direction following the shoreline. If unable to escape,
face the shore and call or wave for help. If tired, float or
tread water until out of the rip current.

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing localized beach erosion and
dangerous swimming conditions.

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 Mobile, AL wrote its last area forecast discussion before this high surf advisory went out at Nov 29, 6:02 PM CST, 1 hour 59 minutes earlier.

Area forecast discussion, Nov 29, 6:02 PM CST, 1 hour 59 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
602 PM CST Thu Nov 29 2018

.DISCUSSION...Updated for latest aviation discussion below.

&&

.AVIATION...
00Z issuance...VFR to MVFR cigs through 30.18z. Expect increasing
mid to low clouds over much of the north central gulf coast region
through 30.18z. Could also see some short periods of light rain
through 30.12z. Winds will be southeast at 10 to 15 kts through
30.18z. 32/ee

&&

.PREV DISCUSSION... /issued 428 PM CST Thu Nov 29 2018/

NEAR TERM /Now Through Saturday night/...Zonal flow aloft tonight
gradually transitions southwesterly across the central Gulf Coast
region Friday ahead of a deepening upper level trough over the Rocky
Mountains. Mostly cloudy to overcast skies will generally prevail
over the region through Friday afternoon with this pattern. Weak
isentropic ascent may result in a few light rain showers, primarily
over southeast Mississippi and interior southwest Alabama late
tonight into Friday. Otherwise, increased southerly surface flow
between high pressure over the western Atlantic and the deepening
area of low pressure over the Rocky Mountains/Plains will result in
increased low level moisture and warmer temperatures across our area
tonight into Friday.

The rest of the near/short term forecast will focus on potential
heavy rain and severe weather impacts across our forecast area late
Friday night into Saturday. A deepening upper level low will lift
northeastward across the central Plains Friday night into Saturday
as a 90-100 kt 500 mb jet lifts northeastward across the Mississippi
and Ohio Valley regions. Another shortwave trough in the mid level
flow will lift northeastward across the northern Gulf of Mexico
Friday evening/night, which may result in an organized area of
convection developing over our Gulf marine zones late Friday night.
Short range guidance has been in relatively good agreement with
bringing this band of organized convection, with an associated heavy
rainfall potential toward the southern Baldwin county AL coast and
much of the western Florida Panhandle along an advancing warm front
late Friday night into Saturday morning. Locally heavy rainfall
amounts of 2-4 inches with localized higher amounts will be possible
especially southeast of a Fort Morgan AL to Florala AL line, where
we will highlight a limited potential of localized flooding Friday
night into Saturday morning. A drier airmass/dry slot in the
southwest flow arrives over our western/northwestern zones, where
decreased rain chances should occur Saturday afternoon into Saturday
evening/night. A good chance of showers/storms may continue across
portions of far southwest and south central Alabama and the western
Florida Panhandle into Saturday night as this part of our area
remains within a moist/unstable airmass underneath minor
shortwave impulses aloft and perhaps also along a weak surface
boundary.

The atmosphere will become increasing unstable across our forecast
area late Friday night into Saturday morning as warm advection
spreads inland. MLCAPE values rising to 500-1000 J/KG in conjunction
with sufficient low level and deep layer shear will bring a threat
of severe storms to our region beginning late Friday night, but
probably more so into early to mid Saturday morning, especially
as warm sector lifts inland. A few organized/rotating storms with
damaging winds and possibly a couple of tornadoes will remain a
threat going into Saturday morning as the warm front lifts inland.
Instability may tend to shift toward eastern/southeastern parts
of the area Saturday afternoon/evening, but decreasing low level
wind profiles may allow for a decreasing severe threat during the
afternoon/evening. /21

LONG TERM /Sunday Through Thursday/...

A powerful mid and upper level jet streak over the Ohio River
Valley on Sunday will lift northeast into the Northeast U.S. by
Monday morning. Lift associated with the right entrance region of
this jet streak will enhance large scale ascent over top of a
surface front that will be stalled out from coastal Alabama
northeast across the Florida Panhandle. The airmass along and
south of the front will remain warm, moist, and modestly unstable.
Deep layer shear should remain strong across the region Sunday
through Monday, but overall mid level lapse rates should remain
weak, which should limit the overall severe weather potential.
Some heavier rainfall will be possible, especially Sunday night
into Monday across coastal portions of the forecast area.

A low amplitude northern stream shortwave will move east across
the area Monday night with the surface front shifting southeast
of the area by next Tuesday. Showers and thunderstorms will come
to an end with strong surface high pressure building in from the
north. Drier and much cooler weather conditions can be expected
for the middle portions of next week. Temperatures should average
several degrees below average. Conditions should favor another
freeze across inland portions of the forecast area by next
Wednesday morning. /JLH

MARINE...

A moderate to occasionally strong southerly flow will prevail
through Friday, before stronger onshore flow develops with
building seas Friday night into Saturday morning ahead of an
approaching low pressure system. Small Craft Advisory criteria
will likely be met over the Gulf waters Friday night and Saturday,
as winds increase to 20-25 knots (and perhaps as high as 25-30
knots well offshore Friday night into Saturday morning). Seas also
build to 7-10 feet during this time. May also have to watch for a
brief period of near gale force gusts well offshore. Showers and
storms return Friday through early next week, with potential for
some severe storms with heavy rain Friday night into Saturday
morning. /21
