Since the midnight gustiness, the development of some light
streamer showers overnight continues and has consequently 
diminished the surface winds over east Texas, therefore this

Area Forecast Discussion
National Weather Service Shreveport LA
115 PM CDT Sun Mar 24 2024

...New AVIATION...

.UPDATE...
Issued at 1037 AM CDT Sun Mar 24 2024

Bottom line up front, no major changes to the forecast for today
as things seem to be trending fairly well this morning. Satellite
imagery continues to show overcast skies across the region and
radar imagery remains fairly quiet. For now, the previous
discussion listed below remains valid.

&&

.SHORT TERM...
(Sunday through Monday)
Issued at 147 AM CDT Sun Mar 24 2024

Transition day across the Four State Region today as southeast
winds return in advance of our big weather maker late tonight and
especially on Monday. Mid and high level cloud cover already
overspreading the region attm as upper ridging begins to buckle
with a longwave trough continuing to deepen into the southwest
Great Basin. It's a lead shortwave ejecting out of this longwave
trough this aftn/tngt that will allow for increased forcing
necessary for the development of showers and thunderstorms across
the Upper Red River Valley, eventually spreading into the Middle
Red River Valley of far NE TX/SE OK and SW AR late tonight towards
sunrise Mon Morning. At the sfc, lee-side cyclogenesis near the
OK/TX Pnhdl will deepen today...allowing for a increasingly tight
pressure gradient across our region. These increasing southeast
winds will allow for increasing low level warm air advection along
with moisture advection that will be setting the stage for the
possibility of strong to severe thunderstorms on Monday. Did not
deviate much from NBM temps or dewpoints Today through Tonight but
did adjust pops slightly across our northwest half for late
tonight.

On Monday, increasing PVA embedded in 160kt upper level jet max
extending from far SW TX through the Middle Red River Valley and
Tenn Valley will result in the increasing forcing necessary for
the development of widespread convection. The low level moisture
return will be quick with lower and middle 60 deg dewpoints
quickly moving northward into our region late tonight and into
Monday in advance of a prefrontal trough. Its this sfc trough
where this convection will develop and move from west to east
across our region during the day and into the early evening, ahead
of a strong cold front that will eventually move into our region
from the northwest late Monday Night into early Tue. Monday's warm
sector in advance of the pre-frontal trough will be best described
as rather weak to minimal instability with MUCAPE values
generally under 1000 J/KG but very strong Deep Layer Bulk Shear
values and strong low level directional shear, especially across
Deep East Texas, into N LA and SC AR. Confidence in strong that
storms will take on a linear depiction on Monday thus, resulting
in a straight-line damaging wind threat but shear vectors will
support weak, short-lived tornadoes embedded in the line. The
possibility of discrete supercell thunderstorms in advance of the
line is more uncertain but this would be more likely across our
far eastern parishes of NC LA during the afternoon and thus, a
more concerning tornado threat would exist. Because of this
uncertainty, SPC continues to advertise a SLGT risk for Monday
across our eastern half but even a slight tick upwards of
instability and/or the hint of discrete supercell thunderstorms
in future model runs would support and ENH upgrade and that
determination will be made later this afternoon.

Thanks for the coordination this morning SPC, LZK, JAN and LCH.
Prelims to follow...13.

.LONG TERM...
(Monday Night through Sunday)
Issued at 147 AM CDT Sun Mar 24 2024

The severe weather threat will end quickly Monday Evening to our
east with the passage of the pre-frontal trough as we await the
upstream passage of the sfc cold front. That front should be
through our northwest half by 12z Tue and through the remainder of
our region by aftn on Tue. The Southern Plains/Lower Miss Valley
will still be under the influence of the upstream longwave upper
trough and it's not until late Wed/Wed Night that this system will
finally eject out across our region. There will be enough upper
forcing with the trough to support at least slight chance pops
across our southwest half Wed Night if we are able to saturate the
low levels of the atmosphere sufficiently to get the precipitation
to the ground which looks unlikely at this time to support
anything greater than slight chance pops for Wed Night attm.

Upper ridging will dominate across the Southern Plains/Lower Miss
Valley for Thu and through at least Sunday for now. The next
upstream trough appears that it will cutoff across the southwest
Great Basin by the weekend which should delay it's impacts across
our region until beyond this 7-day forecast cycle.

.AVIATION...
(18Z TAFS)
Issued at 109 PM CDT Sun Mar 24 2024

VFR conditions will prevail initially with abundant mid and high
level cloud cover at all terminals. Southerly winds will continue
to gradually strengthen and increase in speed, which will bring
more low-level moisture and lowered ceilings into the area. MVFR
ceilings are anticipated at all TAF sites after 25/06z. A line of
strong, possibly severe, thunderstorms are expected to enter
Southeast Oklahoma and western portions of East Texas near or just
before 25/12z, and possibly advancing eastward to affect KTXK,
KSHV, and KLFK near the end of the period. In addition, windy
conditions are likely across much of Louisiana, Southwest
Arkansas, and portions of East Texas between 25/12z-25/18z.
Expect sustained wind speeds of 15 to 25 kts with occasional gusts
near 35 kts.

630 AM CDT Sun Mar 24 2024

This Hazardous Weather Outlook is for our Four-State area of southern
Arkansas, northern Louisiana, eastern Texas and southeast Oklahoma.

.DAY ONE...Today and tonight.

Increasing clouds today, but no rain until after midnight. However, it
will become Windy today ahead of our next approaching rain-maker. In
fact, the arriving showers and isolated thunderstorms will move
across southeast Oklahoma and into our northeastern Texas counties
well before sunrise. However, no hazardous weather is expected
through tonight.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

A Slight Risk for severe storms will be increasing as the ongoing
line of developing thunderstorms moves across I-30 Monday morning.
The daytime heating on will only boost the potential for severe
thunderstorms in the line during the afternoon and evening, over
deep east Texas, southern Arkansas and northern Louisiana. We can
expect that any strong to severe storms will have the potential to
bring down damaging winds, a few tornadoes and brief locally heavy
rainfall. The rest of the week is looking very nice and warm aside
from a few more showers late on Wednesday for eastern Texas under the
parent upper trough.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected until midday on Monday.
