What forecasters said that day

The local office's own words before this high surf warning 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 warning went out at Apr 9, 4:04 AM CDT, 1 minute earlier.

.NEAR TERM...
(Now through Wednesday)
Issued at 404 AM CDT Tue Apr 9 2024

Latest water vapor imagery shows the forecast area under weak upper
ridging, with a closed low moving into the TX/OK Panhandles and a
closed low over the Upper Mississippi Valley. Southerly flow
continues to filter in an abundance of moisture, while several
shortwaves were moving through the southwest flow aloft. This has
led to widespread showers across much of the southeast, though most
of this activity has lifted north of the area. As we head into the
predawn hours, not expecting much in the way of more showers, with
dry conditions likely for the area. Temps will be on the mild side,
given extensive cloud cover, with lows in the lower to mid 60s.

The upper ridge will strengthen a bit through the day as the
southern stream low digs into the Southern Plains. With the moisture
continuing to stream into the area, and weak waves ejecting from the
low to our west, isolated to scattered showers are possible over our
northern zones. That said, the influence of the strengthening ridge
should limit the coverage of showers today. The height rises and
southerly flow will help us warm up a bit today, despite the
lingering cloud cover, and highs will warm into the upper 70s for
much of the area. Not expecting much change in the sensible weather
pattern overnight, with clouds persisting and overnight lows falling
into the 60s. /73

&&

.SHORT TERM...
(Wednesday night through Thursday night)
Issued at 404 AM CDT Tue Apr 9 2024

By daybreak on Wednesday, the closed low over the Southern Plains
will have amplified, though will make very little eastward
progression. We'll start the day under mostly cloudy skies and any
shower/storm activity should remain to our west. This will quickly
change heading into the mid to late morning hours, as the closed low
begins to open and moves towards the Mississippi Valley. At the
surface, southerly flow will increase, with a plume of upper 60s to
potentially lower 70 dewpoints spreading northward over the area. A
stronger shortwave is expected to eject around the base of the
trough Wednesday morning, lifting through the area during the
daylight hours. The main cold front associated with this system will
remain to our west for much of the day, though a prefrontal trough
axis will move through the area as the shortwave lifts
northeastward. Showers and thunderstorms will develop Wednesday
morning in response to the shortwave and prefrontal trough and then
move eastward through the day. Forecast guidance is in very good
agreement about the timing of this activity, with showers and storms
coming to an end Wednesday night as the shortwave lifts out of the
area and the cold front swings through.

This does have the markings to be a multi-hazard event, with severe
thunderstorms, isolated flash flooding, breezy non-thunderstorm
winds, and coastal impacts as well. Overall confidence with this
forecast is fairly high given several days of model to model
consistency. There are some limiting factors for the severe and
flooding concerns, but those factors are becoming a bit more clear
as we head into the day 2 timeframe.

For the severe threat, this system has the makings for a very
impactful event with all modes of severe threats on the table. For
starters, the forcing expected tomorrow is going to be fairly
strong. The initial shortwave will coincide with a strengthening
jet, with the forecast area in the left exit region as the initial
activity begins to enter our area. The low level jet will strengthen
to around 40 to 45 kts, while the mid level jet approaches 70 to 80
kts. This will lend ample 0-6 km bulk shear (60+ kts) and 0-1 km
bulk shear (30+ kts). Additionally, the shortwave will become
negatively tilted, with cooling in the mid levels leading to
sufficient mid level lapse rates. So, organized thunderstorms will
have the ability to sustain themselves. The caveat is the low level
lapse rates which every model seems to be in agreement on being
weak. Forecast soundings do not lend any heating during the day,
which may makes sense as thunderstorms move through, but they may be
underdoing the heating. There is a signal for a weak low level ridge
to hold though much of the event, keeping us capped and limiting the
coverage of severe thunderstorms. But my confidence on this is not
very high and given the other parameters in place and the overall
synoptic setup, will lean towards us heating a bit more than
forecast guidance suggests and removing the cap over much of our
area. The main window for the severe thunderstorms will generally be
during the afternoon and early evening hours when the best heating
will overlap the low and mid level jets.

The flooding threat is a bit less certain than yesterday, mainly due
to guidance moving activity through a bit quicker. There's
reasonable confidence that the most of the area will remain dry
before the main showers and storms move through, so our antecedent
conditions are in good shape. The activity will move through in
about a 6 to 12 hour period, with storm total rainfall amounts in
the 2 to 4 inch range. FFG is relatively high, so overall it appears
that the threat for flash flooding will remain limited. This threat
will increase for any areas that see training storms and/or intense
rainfall rates, all of which are too uncertain at this point to
issue a Flood Watch.

That still leaves the wind, marine, and coastal hazards which are
the most certain of the forecast. The pressure gradient will tighten
quite a bit, with Gale conditions expected to begin Wednesday
afternoon and continue through the overnight hours. Winds inland
will be right on the edge of Wind Advisory criteria so will hold off
on issuing one on this shift. Additionally, strong onshore flow will
persist and High Surf conditions (8+ feet) are likely to begin late
Wednesday afternoon and continue into Thursday morning. A High Risk
of Rip Currents is also in effect for this period as rip currents
are likely. And finally, coastal flooding is also anticipated,
though there is less certainty on if Coastal Flood Warning criteria
(3+ feet) will be met.

As mentioned above, showers/storms will exit the area Wednesday
night, with the main trough axis moving through and the cold front
exiting the area by daybreak on Thursday. Northwest flow will take
over, with dry air filtering into the region. Seasonably mild
conditions are expected during the day, with highs warming into the
lower to mid 70s. Overnight lows will fall into the mid 40s to lower
50s Thursday night. /73

.LONG TERM...
(Friday through Monday)
Issued at 404 AM CDT Tue Apr 9 2024

The aforementioned upper-
level trough finally begins to lift away from our area at the start
of the period, entering into the western Atlantic by Saturday. In
its wake, northwesterly flow aloft becomes established across the
area, helping to bring in a much drier airmass from the north. Upper
ridging begins to amplify across the central US on Monday helping to
maintain this northwesterly flow into the start of the week. At the
surface, high pressure builds in over the ArkLaTex region on Friday
and slowly pushes eastward throughout the weekend. With subsidence
in place from this high, and the drier airmass present (PWATs less
than an inch), no rain is forecast through the period. Temperatures
will steadily increase through the period as winds shift from
northwesterly on Friday to southerly by Saturday night (due to the
high pushing overhead and moving off to our east). Highs will
increase from the mid 70s on Friday to the low to mid 80s by Sunday
and Monday. /96

&&

.MARINE...
Issued at 404 AM CDT Tue Apr 9 2024

A tightening of the pressure gradient between a developing
surface low over the Plains and a surface just off the East Coast
will bring Small Craft level winds starting tonight. A
significant portion of area waters will see Gales conditions
beginning late Wednesday afternoon ahead of an approaching front
through Thursday afternoon behind the front's passage. There is
expected to be a lull to below near the front's passage. Winds
will ease Friday into the weekend and become more variable as
surface high pressure moves over the area. /16/73
