.DISCUSSION...
Issued at 315 PM CDT Sat Jun 1 2024

Through Sunday: An active weather pattern will continue in the
near term as rain and thunderstorms are expected to redevelop
later on in the evening.

Short term guidance continues to show a shortwave disturbance
developing a convective complex in the southwest and pushing the
previously mentioned complex into the ArkLaMiss region during the
evening/overnight hours. With instability still in place (MLCAPE
values near 2000 J/kg, lapse rate between 6-7 C/km) and decent
precipitable water values near 1.5 inches, isolated severe weather
and flash flooding will remain a concern through the evening,
mainly over southern and far eastern portions of the area, and
HWO graphics will continue to reflect the risk areas. Overnight
temperatures are expected to be in the upper 60s and lower 70s.

Rain and thunderstorms are expected to start off Sunday morning as a
shortwave disturbance moves off towards the east. A strong storm or
two could be possible during Sunday morning but severe weather is
not anticipated. As the shortwave progresses through the area, flash
flooding threat should diminish as the afternoon progresses and
rain chances will diminish late afternoon into the evening. /SW/

Sunday night through Friday night: Active westerlies will
continue through the long term forecast bringing the potential for
additional MCS activity and perhaps the threat for severe weather
and localized flash flooding. Convective rainfall should be most
prominent over northern portions of the area Mon-Tue, but it
appears the Wed-Fri time frame will have the greatest concerns
for the area as whole when a significant cold front is expected to
push farther south toward the forecast area. /EC/

.AVIATION...
(18Z TAFS)
Issued at 108 PM CDT Sat Jun 1 2024

VFR flight conditions for majority of TAF sites with the following
exceptions: MEI/GWO/HKS are under MVFR flight conditions and GTR is
under IFR flight conditions to start the TAF period.
Showers/thunderstorms have decreased throughout the morning, however
redevelopment may be possible this afternoon and evening in eastern
MS and southern TAF sites as instability and a moist airmass remains
over the region. Shower/thunderstorm potential and cloud cover will
remain over the area into Sunday, resulting in lower ceilings and
VFR/MVFR flight conditions for Sunday morning. /SW/
