.SHORT TERM...
(Today through Sunday night)
Issued at 255 AM CDT Fri Apr 4 2025

A very full shortterm forecast is in store. One look across the US
and the current situation is very clear: quasi-stationary front
stretches from southwest to northeast from southwest Texas to
CenAR into western KY; high pressure dome is standing resolute
over FL; upper trof is nearing the Rockies. The combination of all
these features will make up the busy forecast. Let`s break it
down by hazard...

Severe TL;DR: Brief period of severe storms possible in extreme
inland SE TX / W LA zones this afternoon. Any storms that can
develop will carry all hazards. The chance of severe thunderstorms
is low.

Saturday`s severe risk will begin late morning and will
continue into early morning hours Sunday. Super cells with all
hazards will be possible across SE TX from noon to early evening;
from mid afternoon to midnight in SW and CenLA. Front comes in
from the west in the form of a congealed line of stronger storms
with heavy rain starting mid afternoon. The line will also carry
all storm hazards, including heavy/flooding rain, as it moves very
slowly eastward from early afternoon into Sunday.

Wind... Strong pressure gradient between the series of lows
developing east of the Rockies and high pressure dome is going
nowhere. Winds overnight have remained elevated, particularly
along and south of I-10, thus the Wind Advisory was started early.
Remaining zones north of I-10 will join the Advisory at 1 PM as
strong winds spread inland. This happens when daytime diurnal
action causes the gradient to tighten further and as mixing pulls
down stronger winds from aloft. Expect south winds 20 to 25 MPH
with gusts to 40 MPH; although sustained winds and gusts could be
higher. We`ve been overachieving on winds during daytime hours in
the last several wind events.

Much of the same can be expected Saturday ahead of the approaching
cold front. Another Wind Advisory will likely be issued with the
daytime package.

Coastal Flooding... Strong winds are exacerbating water levels
around high tide time. Expect nuisance coastal flooding today and
Saturday as water levels are forecast to reach 1.0 to 1.5 feet
MHHW around high tide time.

Last but not least... Severe Weather (Today)... Upper trof is set
to amplify as it crosses the Rocky Mountains later today. This
extra forcing will help to goad along the aforementioned
stationary front. The front will slowly sag southward this
afternoon but will remain north of the forecast area. A few
isolated/discrete cells may form in response to its presence in
Deep Southeast Texas during the afternoon and early evening, but
chances are very low of severe weather materializing for the
forecast area. Any storms that can develop can carry all storm
hazards. Again, this chance is low.

Severe Weather (Saturday)... Upper low really starts spinning up
and rolling east on Saturday. Guidance indicates several
perturbations will swing through the upper low as it moves into
central Texas Saturday afternoon. This "troughiness" could result
in an area of localized increased vorticity and shear in the
afternoon and evening. Combined with dewpoints in the 70s and CAPE
above 2300 J/kg, updrafts will have little issue developing and
maintaining themselves overtop the entire forecast area.

Bulk shear falls largely less than 30 knots over the region until
after noon. A larger increase to 30 to 40 knots occurs after noon,
along with increased forcing overall from aloft. This could
denote the start of semi-discrete super cell-type features in SE
TX/SW LA as the front enters east-central Texas. The front should
make quick progress into east Texas through the afternoon hours,
however, aloft, the low gets swiftly pulled to the northeast
around the northern fringe of the high pressure ridge. This
decrease in forcing will cause the front to slow to a crawl as it
moves into LA in the later afternoon/evening. At this point, two
scenarios will likely unfold: 1. discrete cells developing in the
env ahead of the line (central and east LA) which swiftly move
northeast; 2. those storms along the front congeal into a line of
strong storms and heavy-rainers that move slowly eastward. Expect
at least showers and thunderstorms to linger into Sunday until
upper trof fully swings through, clearing our region of rain. Much
cooler and drier weather will move in thereafter.

All hazards will be possible throughout the entirety of Saturday
from mid morning into the early morning hours Sunday. Rotating
cells will have the ability to spin down a tornado, mix down
strong wind gusts and/or carry large hail. Then, along the line,
damaging winds could result in surface damage as well as embedded
tornadoes. Stronger updrafts within the line could produce large
hail.

Remain very weather aware from mid-morning into the overnight
period. Ensure you have the means to receive warnings, and heed
them when/if they come.

.LONG TERM...
(Monday through Friday)
Issued at 255 AM CDT Fri Apr 4 2025

Much much cooler and drier conditions are the talking point of the
longterm forecast. Strong CAA behind this weekend`s cold front
will bring about morning low temps in the mid to upper 40s by
Monday morning, low to mid 40s Tuesday morning. Monday will
largely be the coldest day in the longterm with highs in the 60s.
By Tuesday, high pressure over the CenUS will slide east to the
ern seaboard, allowing the local airmass to moderate. Daytime
highs will return to the 70s Tuesday and Wednesday before hitting
the 80s once again Thursday.

With high pressure in control of the forecast, expect dry
conditions through the period.

.AVIATION...
(12Z TAFS)
Issued at 638 AM CDT Fri Apr 4 2025

Wind gusts have stayed elevated overnight, particularly at coastal
terminals, with some sites reporting occasional gusts 25 to 30
knots. Expect this trend to continue with another day of strong
south winds and gusts on tight pressure gradient. The exception
being AEX where winds off the Gulf don`t quite reach. Central LA
will begin gusting after sunrise, as diurnal effects take over.

Moisture advection off the Gulf persists on these elevated winds,
so expect MVFR CIGs to prevail over the period. CIGs are not
forecast to drop below 1000 feet in this period with winds keeping
surface layers reasonably mixed out.

Quasi-stationary boundary stretching from southwest Texas to
Kentucky will ooze southward slightly today. A few isolated showers
and storms will be possible across inland southeast Texas and
north-central Louisiana, but ultimately convection should remain
well north and pose no issue to AEX. The chance is low enough that
mentions of convection were left out of AEX at this time. Monitor
later TAF issuances / radar for any convective trends.

.MARINE...
Issued at 255 AM CDT Fri Apr 4 2025

Southeast winds of 20 to 30 knots with gusts to 36 knots and seas
of 6-11 feet will continue through Saturday. A cold front will
push through the coastal waters Saturday afternoon/night
accompanied by a squall line capable of producing severe weather
including damaging winds, large hail, waterspouts, frequent
lightning and heavy rainfall. Winds will turn offshore and relax
behind the front Saturday night and remain that way through mid
next week. Seas, particularly in 20 to 60 nm waters, will remain
in the 3 to 7 foot range through at least Monday morning.

&&

.FIRE WEATHER...
Issued at 255 AM CDT Fri Apr 4 2025

Very warm, humid and windy conditions will prevail today and
Saturday as the area remains caught between a ridge of high
pressure to the east and a series of developing lows across Texas
and the southern Plains. An upper trough will guide a cold front
through the area late Saturday accompanied by a squall line
capable of producing severe storms and heavy rain. Significantly
cooler, drier air will filter into the region on northwest winds
behind the front Saturday night through the middle of next week.

Daytime low RH percentages will range from the mid 50s inland to
around 70 percent at the coastline today and Saturday. By Sunday
and into the start of next week, these values will fall to the mid
20s to mid 40s.
