.SYNOPSIS...
Issued at 310 PM CDT Wed Jun 26 2024

Showers and thunderstorms will continue moving through the Mid-
South this afternoon and evening. Some storms may be strong to
severe with damaging winds, large hail, and flash flooding as the
primary threats. Temperatures will be slightly cooler tomorrow
with highs in the upper 80s to near 90 degrees. A warming trend
will bring the return of hot conditions to the Mid-South on
Saturday, possibly as early as Friday in parts of the MS Delta. A
cold front will bring cooler temperatures and greater
precipitation chances on Sunday and Monday, prior to hot
conditions returning to the region on Tuesday.

.DISCUSSION...
(This evening through next Tuesday)
Issued at 310 PM CDT Wed Jun 26 2024

Surface analysis places a cold front moving toward northern
portions of the Mid-South with an area of showers and
thunderstorms ahead of this feature. A few of these storms may be
strong/severe for the remainder of the afternoon/evening with
scattered damaging wind gusts and isolated instances of large hail
as the primary threats. Flash flooding may also occur in areas
where persistent convective activity trains over the same area.

The cold front will move through the Mid-South overnight bringing
a brief relief from recently hot conditions across the region
tomorrow. Thereafter, warm and mostly dry conditions will prevail
in the later portions of the week, as mid-level ridging builds
across the Mid-South. Heat index values look to stay below heat
advisory criteria on Friday, but a few locations in the MS Delta
may get close with heat index values from the NBM coming in around
105 degrees. Saturday looks to be even hotter, as mid-level
heights continues to rise. Temperatures across the region on
Saturday will increase into the mid 90s with dewpoint values in
the mid to upper 70s, making heat advisories and the possibility
of an excessive heat warning increasingly likely.

The mid-level ridging looks to break down on Sunday as troughing
amplifies over the northeastern U.S., which puts the Mid-South in
a northwest flow regime. As this occurs, a cold front is forecast
to move through the Mid-South, bringing slightly cooler
temperatures and greater precipitation chances to the area on
Sunday and Monday. However, this trend does not look to last long,
as temperatures on Tuesday rebound into the mid to upper 90s.
Heat index values look to reach or exceed 105 degrees around this
time, making the return of heat headlines likely on Tuesday.

.AVIATION...
(00Z TAFS)
Issued at 639 PM CDT Wed Jun 26 2024

Redevelopment looks to continue over areas west of the Mississippi
River through around 04Z as an MCV continues to rotate over NE
AR/MO Bootheel. Pop-up showers out in front of this redevelopment
are possible across all terminals resulting in a VCSH at all TAF
sites. Conditions look to teeter back and forth between VFR and
MVFR as this redevelopment occurs. As showers and thunderstorms
clear the Mid-South, around midnight, MVFR/IFR conditions are
expected to prevail into the early morning across the airspace.
Fog looks to develop MKL/TUP as convection clears the area.
