Flash Flood Warning 49, NWS Shreveport, LA

...New AVIATION...

.SHORT TERM...
(This evening through Tuesday Night)
Issued at 253 PM CDT Mon Jun 3 2024

Active weather will continue to impact the Four State Region with
yet another round of severe thunderstorms possible through the
evening. This is due to an ongoing synoptic setup (ridging to our
west, troughing to our northeast) allowing for northwesterly flow
to continue channeling disturbances across the Southern Great
Plains into the Four State Region. Including the latest round
expected to arrive through this evening into the night. Given the
conducive enough atmosphere, the SPC has accordingly issued a new
Severe Thunderstorm Watch until 8PM CDT. Convection associated
with this disturbance will diminish by tomorrow morning and
temperature maximums/minimums will remain in the lower 90s/low-to-
mid 70s, respectively. /16/

&&

.LONG TERM...
(Wednesday through next Sunday)
Issued at 253 PM CDT Mon Jun 3 2024

A fairly active weather pattern will continue through the rest of
the week into the weekend across the Four State Region. The
aforementioned synoptic setup will not change much until ridging
across the Four Corners/West Texas builds eastward into our area
by the weekend. Until then, additional MCSs cannot be ruled out
and are notoriously tricky to catch in their initiation, speed,
and intensity by high-resolution guidance, reducing ideal forecast
certainty. That said, the best windows for more activity will be
on Wednesday and later this weekend as a frontal boundary somewhat
interrupts the best environment for convection between those two
times. Temperature maximums/minimums will remain near-to-above
normal in the lower 90s/mid-70s, respectively. /16/

.AVIATION...
(00Z TAFS)
Issued at 555 PM CDT Mon Jun 3 2024

A large NE to SW convective complex continues to push SSE across
NE TX/Srn AR, and will affect the I-20 terminals in E TX/N LA between
00-04Z, resulting in gusty winds to 50kts, reduced vsbys, low
MVFR cigs, and extreme turbulence. These storms may eventually
reach LFK as well, but have lower confidence in this occurring,
although some tempo thunder was included here as well from mid to
late evening. In wake of the convection, VFR conditions will
return, and should remain VFR with elevated cigs through the
overnight hours over much of the region. Some MVFR cigs may
develop/affect LFK if the convection does not push through this
area later this evening. However, another thunderstorm complex may
develop overnight over Ern/SE OK, and spread SE into NE TX/SW
AR/N LA by/after 12Z Tuesday, affecting the area terminals through
the morning before diminishing by midday/early afternoon. In its
wake, VFR conditions will return, with elevated convective debris
lingering through the afternoon, with a scattered cu field
returning with diurnal heating as well. SSE winds 5-10kts, except
gusty in/near the convection, will become more Srly 9-12kts in
wake of the second round of convection Tuesday morning/afternoon.

Hazardous Weather Outlook

257 PM CDT Mon Jun 3 2024

This Hazardous Weather Outlook is for north central Louisiana,
northwest Louisiana, east Texas and northeast Texas.

.DAY ONE...This afternoon and tonight.

A complex of thunderstorms is developing across Oklahoma and has
approached the Four State area this afternoon and evening, some may
be severe with damaging winds primarily. Overnight, we may see a
second complex of thunderstorms arriving in southeast Oklahoma and
southern Arkansas by daybreak. These thunderstorms have been
progressive, but due to the widespread rains lately, flash flooding
may accompany the lightning and gusty winds with some heavy downpours
on our wet soils.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

Isolated to scattered showers and thunderstorms will persist to some
extent during midweek. However, the coverage and intensity of
thunderstorms should see a decrease each day through Thursday. Then,
we can expect another weak cold front to arrive on Friday with more
widespread thunderstorms affecting our area in this same night and or
day pattern. The weekend now looks to see the front become
stationary west of I-49, acting to focus areas of rainfall.
Additional rivers and bayous will see rises and minor flooding
continue into next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed.
