.UPDATE...
Issued at 1020 PM CDT Mon Jun 9 2025

Much quieter conditions are in place this evening compared to
24hrs ago, with the mid-evening sfc analysis indicating a
stationary front that extends across Cntrl LA/Deep E TX and into
NCntrl TX. Despite NW flow in place atop this bndry this evening,
drier air aloft and the lack of any perturbations in this flow
pattern will yield continued quiet conditions overnight, although
a weak H925-850 trough that will drift S into Deep E TX/Cntrl LA
overnight may result in some cu development over these areas, with
the latest satellite imagery depicting considerable convective
blowoff from ongoing convection over portions of W and WCntrl TX
that should result in elevated cigs spreading into portions of E
TX/Lower Toledo Bend Country late tonight. But the arrival of
these cigs late should not impact min temps tonight, with readings
expected to fall to near seasonal norms across much of the area.

The only changes needed to the current forecast were to drop pops
tonight for the Srn zones near the stationary front, and to reduce
sky cover at least for this evening before additional cu/elevated
cigs develop late near the H925-850 trough. Very minor tweaks to
min temps were also made, but not enough to influence wording.
Otherwise, the remainder of the forecast is on track, as
convection that develops overnight across W TX will build farther
E across NCntrl TX Tuesday morning and eventually into the Srn
half of the region by afternoon along the stationary front, ahead
of a weak perturbation aloft that will translate ESE along the
bndry.

Zone update already out...grids will be available shortly.

.SHORT TERM...
(This evening through Tuesday Night)
Issued at 154 PM CDT Mon Jun 9 2025

Though temperatures have recovered this afternoon, albeit somewhat
cooler when compared to recent days, advertised hi-res showers
and thunderstorms have struggled to materialize as a surface
boundary near I-30 remains stalled. Best opportunity for
convective coverage will be across the southern zones and south of
the FA through the late afternoon and evening, co-located within
the highest diurnally driven instability gradient. The Storm
Prediction Center continues to highlight this region in a Marginal
Risk, with the extreme SE corner of LaSalle Parish in a Slight
Risk, where gusty winds and hail remain the primary hazards at
play.

The overnight period will trend mostly quiet, though there is some
potential for a few weaker showers to briefly prevail across the
southern zones. Hi-res and deterministic solutions depict that
energy embedded within the mid-level flow across West Texas
tonight will kick east, ultimately moving into the southern
counties and parishes tomorrow morning, supporting showers and
thunderstorms Tuesday afternoon. Guidance continues to highlight
a corridor for the highest PoPs along I-20 and south, with highs
in the mid to upper 80`s, and low 90`s. For now, SPC is only
highlighting the extreme southern zones of the FA in a Marginal
Risk, along and south of a line from Lufkin, TX to Jena, LA.

Heading into Wednesday, southwest flow will begin to influence the
region, and with it the pesky perturbations within the mid-level
regime. Given the location of the upper ascent, highest confidence
in PoPs through Wednesday/Wed PM will be across the western and
southwestern zones, before more equal coverage for all into Thursday
AM.

.LONG TERM...
(Wednesday through next Sunday)
Issued at 154 PM CDT Mon Jun 9 2025

With an extended period showcasing the return of a prolonged
southwest flow regime, daily showers and thunderstorms will be in
the forecast. For now, closely eyeing 7 day QPF totals across the
western and northwest zones of the FA where totals between 3-5" may
be possible. Along with this, the threat for excessive rainfall will
be in the vicinity or partially covering the Four State Region
through days 4 and 5 in the extended. General theme across these
outlooks is a concentration on the western zones of the local FA,
given the synoptic setup, and potential for heavy rainfall over
the same locations. This will be worth monitoring as we move
through this week.

Aside from the convective prospects, with warm gulf air advecting
into the region, temperatures will be near seasonal, trending in the
upper 80`s and low 90`s for many through next weekend. While the
heat will be noticeable, humidity will be a factor given the
airmass in play. Higher dew point temperatures through the period
can easily support heat indices nearing the triple digit mark.
That being said, this will depend heavily on the influence of
afternoon convection and coverage, but something to keep in mind
as we head deeper into summer.

.AVIATION...
(06Z TAFS)
Issued at 1230 AM CDT Tue Jun 10 2025

For the 10/06Z TAFs, VFR conditions look to prevail across area
airspace, particularly north of I-20, where near SKC conditions
will continue. Elsewhere, SCT high clouds will be the primary sky
cover of note. The only exception will be KLFK, which will see
lowering to MVFR and possibly IFR CIGs overnight towards
daybreak, and which stands the best chance of seeing scattered
showers and storms returning during the daytime hours. Light and
variable winds overnight will adopt a more easterly orientation
through the day, while remaining fairly light at speeds of not
much more than 5 kts and little to speak of in the way of gusts,
up to 10 kts, if any occur.
