Severe Thunderstorm Warning 52, NWS Shreveport, LA

Area Forecast Discussion...UPDATED

...New AVIATION...

.UPDATE...
Issued at 1146 AM CDT Tue Apr 9 2024

Decided to make some adjustments to POPs based on current and
forecasted radar trends. Also, make some adjustments to temps, as
rain has kept things a little cooler than originally anticipated.
Otherwise, the remainder of the forecast remains unchanged. One
thing of note, short-term progs continue to hint at a MCS
developing across East Texas and moving along and just south of
the I-20 corridor of East TX and North Louisiana this afternoon
into the early evening hours. This will need watching, as more
severe wx could be possible, along with additional heavy rain. All
risk could be in play. /20/

.AVIATION...
(18Z TAFS)
Issued at 159 PM CDT Tue Apr 9 2024

Cigs have mostly lifted/become VFR early this afternoon in wake of
the morning convection/outflow bndry that affected Deep E TX/N
LA, but cigs remain IFR/low MVFR farther WNW over much of E TX/Srn
AR where additional convection has developed. While much of this
convection remains elevated, they may tend to root more towards
the sfc across Deep E TX by mid-afternoon before shifting into
NCntrl LA during the late afternoon/early evening. Thus, locally
gusty winds and IFR cigs may affect LFK, whereas locally heavy
rain will tend to result in vsby reductions at TYR/GGG/TXK/SHV
before eventually affecting MLU by early evening. Additional
convection redevelopment will remain possible through the
evening/overnight across NCntrl LA/adjacent Deep E TX, while
tapering elsewhere for several hours as we await the next MCS that
will develop over the TX Hill Country late this evening, and
quickly shift E into the region after 09-10Z Wednesday. Have
maintained prevailing TSRA with IFR cigs for all terminals
around/after daybreak, with the stronger convection quickly
diminishing from W to E by mid to late morning. Some residual
rains may linger through the remainder of the TAF period. E winds
5 to 10kts will continue this afternoon through tonight. /15/
